Lab member Dr. Michael Hemming attended the AODN Hackathon last week (7-9th May) in Hobart. The hackathon was a great opportunity to learn how to access IMOS data in various ways using Python, how to load and plot cloud-optimised data sets, how to efficiently code using AI as a tool, and how to find, load, and visualise IMOS data sets using R. After the tutorials, attendees separated into groups to work together on various projects.
Michael presented a tutorial on how to load, plot, slice, and save extreme ocean temperatures contained in the Australian Multi Decadal Ocean Timeseries EXTreme (AMDOT-EXT) data products using Python and R. The tutorials and project code are available on the AODN IMOS-hackathon (Github repository).

The Moana project is wrapping up after 5 years of research, and a film has been made to reflect on the highlights of this nation-wide research project.
In the film (available here), Prof. Moninya Roughan shares her thoughts on what the Moana Project means to her.
NSW experienced the heaviest rainfall in 4 years during the first weekend of April. In parts of Sydney, more than 160 mm of rain fell. This excess rainwater made its way to the ocean, turning the normally turquoise blue coastal waters brown. The contrasting colours where the brown water from the river met the beautiful blue ocean water could be seen off the New South Wales south coast.
Prof. Moninya Roughan commented on this rare phenomenon for an ABC news article, and was interviewed on ABC South East NSW Breakfast.

Dr. Amandine Schaeffer spoke on ABC radio Illawarra this morning (20 March) to discuss the BluebottleWatch project. Dr. Schaeffer is leading the BlueBottleWatch project, along with Surf Life Saving Australia researcher Dr. Jaz Lawes.
The project aims to develop an online tool that will warn beachgoers about the likelihood of bluebottles invading the beach. This will hopefully reduce the number of stings treated by surf lifesavers, which presently is more than 40,000 around Australia every year.
The start of autumn has delivered extreme heat to NSW land and ocean. There has been a spell of abnormal heat lasting 10 days, with many inland regions exceeding 5C above average. Sydney's average maximum this month was 3.5C above the long-term average.
The waters off NSW are also extremely warm, with temperatures exceeding the 90th percentile: a threshold that is used to define marine heatwaves. Prof. Moninya Roughan was asked to comment on the abnormal ocean conditions for an ABC News and Guardian article, and was interviewed live on air by ABC news (see video below). Prof. Roughan also spoke live on ABC illawarra and ABC Darwin radio.

BluebottleWatch French collaborators joined the Sydney team in January 2024 to test 3D-printed Bluebottle models that they designed in real ocean conditions. The fieldwork off Botany Bay was a great success, with the bluebottle models equipped with GPS and satellite communication systems being deployed and received over multiple days under varied weather and sea states.
The observations will now be analysed, with an aim to create a lagrangian model depicting Bluebottle movement (speed and direction) resulting from winds and currents. This model will then be integrated into ocean circulation models to understand the origin and variability of Bluebottles.

New research led by Dr. Neil Malan and including contributions from lab members Prof. Moninya Roughan and Dr. Michael Hemming show that extreme rainfall in 2022 (the wettest year on record) led to freshwater plumes that extended further out from the coast than was previously thought possible. These plumes were 50 m deep, and remained offshore for months. A new 'double-stacking' dynamic was also observed resulting from the multiple rainfall events in 2022.
This research used data from 36 autonomous ocean glider missions over 13 years, and salinity observations at the Port Hacking 100 m depth mooring site. Such events may become more common as extreme rainfall events are projected to become more frequent as a consequence of climate change, hence continued observations are vital.
Dr Neil Malan and Prof. Moninya Roughan co-wrote a Conversation article on this work, and Neil also appeared on National ABC Breakfast.

This week, a lab trip took place to visit the Water Research Lab - UNSW, located at the foot of Manly Dam. Professor Mitchell Harley kindly conducted a tour around the facilities of the oldest lab of its kind in Australia, with a history spanning more than 60 years.
For more details about what WRL does, you can visit the Water Research Laboratory website.
Different types of experiments are currently being conducted at WRL, with some of them in partnership with BEES.
Lab leader Prof. Moninya Roughan presented the lab's research at the UNSW DVC Research & Enterprise strategy day last week (30th November). Moninya explained how ocean eddies drive extreme "ocean weather" off New South Wales, bringing in masses of warm water which sometimes persist for months.
Moninya also presented how data collected during the recent RV Investigator cruise will help in understanding how these eddies behave, and how the fishing industry is contributing data through citizen science approaches (FishSOOP).

A video summarising the RV Investigator voyage last month is now publicly available on the UNSW Community Youtube Channel. This video, created by Bella Charlesworth (communications officer onboard), explains the importance of this cruise and provides a glimpse of what life was like onboard.
Lab members onboard the RV Investigator returned home today (November 2nd) after 24 days at Sea. During this time essential data was collected for understanding eddies and currents off southeastern Australia. And to the lab's suprise the ship was welcomed back to Sydney by a Humpback whale!
As the lab members returned, a monster warm-core eddy was forming 50 km offshore threatening to raise ocean temperatures close to Sydney over the next days to weeks. Using ship data, and deployed drifters and Argo floats, they estimated that the 400 km wide eddy holds 30% more heat than normal for this part of the ocean, and determined that its currents are moving at 8km an hour and temperatures deep underwater are up to 3 degrees celsius above normal.
For more details you can read the conversation article written by Prof. Moninya Roughan, Dr. Amandine Schaeffer, Dr. Junde Li, and Associate Prof. Shane Keating, which was also picked up by the Guardian, Swellnet, Timeout, UNSW News Room, and Mirage News.

Lab members onboard the RV Investigator have so far sampled two distinct eddies and crossed multiple fronts with an aim to understand how oceanic eddies are structured, how they interact with one another, how they interact with the shelf, and what happens in eddy fronts. They have been busy using the ship's Triaxus towed system and have undertaken multiple CTD profiles. Additionally, they have deployed drifters, radiosondes and Argo floats (including a biogeochemical one).
The voyage is a large interdisciplinary effort supported by several IMOS data streams. Read more here.

This month lab members will board the RV Investigator to investigate the dynamics of eddies, their associated air-sea fluxes and impact on biological productivity, and to collect data useful for prediction.
Chief Scientist Prof. Moninya Roughan has been interviewed by the ABC, Sydney Morning Herald, and appeared on 7 News to speak on the importance of this cruise, while cruise investigator Prof. Shane Keating and Moninya have also written an article for The conversation.
The RV Investigator docked at White Bay Cruise Terminal a week ahead of departure. During this time members of the public were given the opportunity to take a peek inside the ship. UNSW science and other media groups also took part in a tour.
And the UNSW Coastal and Regional Oceanography Lab is expanding! A brief introducion of our new members:
Cuong is a post-doc, with expertise on coastal ocean dynamics, using observations and modeling output to explain key processes driving changes in the ocean. Cuong earned his Ph.D. at the University of Littoral Cote d'Opale, where he investigated the dynamics of the Gulf of Tonkin and evaluated the effects of fine-scale processes on particulate material and phytoplankton distribution.
Post-doc Marina, is delving into the complexities of eddies and their interactions within the East Australian Current system. In the past, Marina's research included post-doctoral work at the University of East Anglia (UEA), where she studied air-sea interaction and extreme precipitation events in the eastern Indian Ocean, as well as completing her Ph.D. on the dynamics of Antarctic coastal currents.
The physical oceanographer Gaby, now with a post-doc position focusing on coastal ocean dynamics and bio-physical interactions, applies Lagrangian particle tracking models to study marine connectivity. In her previous role at the National Oceanography Centre (NOC) in Liverpool, UK, Gaby conducted research on various environmental issues, including plastics pollution and marine ecosystems resilience. She holds a Ph.D. in biological oceanography and an MSc in physical oceanography.
Xiaowen, currently pursuing her Ph.D. at the Coastal and Regional Oceanography program at UNSW, focuses on ocean data processing and the large-scale effects of ocean waves. Her work involves high-resolution processing of ocean wave model data and the utilization of non-stationary sea surface temperature data to predict wave patterns. Xiaowen's academic journey began at the Ocean University of China.
A warm welcome to our new lab members!

Amandine Schaeffer, Alex Sen Gupta, and Prof. Moninya Roughan's Article on MHWs in The Conversation received wide coverage, following publication of scientific research in the Nature Journal; Communications Earth & Environment.
Marine Heat Waves are prolonged periods of unusually high marine temperatures, and can occur in surface or sub-surface waters. They are a relatively recently studied phenomenom which look to be increasing in frequency and intensity as a result of climate change. The commonly used definition is that of Hobday et al 2015: A hierarchical approach to defining marine heatwaves "Specifically, we consider an anomalously warm event to be a MHW if it lasts for five or more days, with temperatures warmer than the 90th percentile based on a 30-year historical baseline period".

New FRDC project FishSOOP was featured in IMOS news this month. This collaborative pilot project, led by Dr. Véronique Lago and Prof. Moninya Roughan, is working with fishers to collect real-time ocean observations where they matter most. IMOS is a partner of this Fisheries Research and Development Corporation (FRDC) funded pilot project (2022-007) with Fishwell Consulting and the University of New South Wales.
You can read this news article here.
Early career researcher, Maxime Arnoud, who visited the lab in 2023, has featured in a Boiling Point Science podcast episode to talk about Bluebottles.
You can find this episode on Spotify here.
New biological oceanographer Daniel Hewitt started his position this month. Dan is working to predict the occurrence of bluebottles (Physalia physalis) on Australian beaches for the BlueBottleWatch project. His focus is using a combination of observations (e.g., sightings), ocean observations and hydrodynamic model outputs to develop statistical models that can forecast 'sting risk' for beachgoers.
He recently completed his PhD at UNSW in collaboration with NSW DPI Fisheries, where he used a combination of acoustic telemetry and biophysical modelling to investigate aspects of the fisheries ecology of Giant Mud Crab (Scylla serrata) in southeast Australia.
Welcome to the lab, Dan!
Field technicians Tim Austin, Stuart Milburn and Zac Anderson successfully serviced the Sydney moorings (SYD100, SYD140, PH100) this month via the DPI Fisheries boat Solitary Ranger. This was their first servicing of the moorings without Clive Holden (Oceanographic Field Services) who has been servicing these moorings for 10+ years, and the NSW-IMOS technicians will continue to service these moorings into the foreseeable future.
This was also a great opportunity to compare temperature measured by the MOANA sensors (used for the FishSOOP project) with the other deployed sensors.

Prof. Moninya Roughan and past/present team members Michael Hemming, Fernando Sobral, Neil Malan, Colette Kerry and David Gwyther presented their work this month at the Australian Marine Society Association (AMSA) 2023 conference in the Gold Coast, Australia.
The following Posters and talks were presented at the conference:
Photographs taken during the conference.
Dr Amandine Schaeffer commented on a new marine heatwave study showcased in AGU's science news magazine Eos this month. This new study, led by Dr. Dillon Amaya (Physical Sciences Laboratory, NOAA, USA), discovered that more intense, longer-lasting marine heat waves can effect bottom depths independently from the surface.
Amandine pointed out that this new study is not the first to measure marine heat waves below the surface, as there are previous smaller-scale studies near Australia and in the tropical western Pacific. This new study "shows the need for subsurface understanding and subsurface observations to really see what's happening in terms of extremes below the surface", Amandine said.
Oceanographic field technicians Tim Austin and Zac Anderson visited the Coastal Ocean Dynamics Applications Radar (CODAR) sites close to Newcastle last week for calibration of the systems. During the calibration process, a transponder and portable aerial were used to triangulate the transmission (TX) and reception (RX) aerials of the CODAR systems, which enabled the truthing and refinement of their measurements. This involved navigating a vessel offshore to various locations along the perimeter of the aerials' range.
Thank you Tim and Zac!

Luke Matisons started his PhD this month. He is studying the dispersal characteristics of eddies in the EAC using drifters and Lagrangian particle tracking to better understand the impacts mesoscale and submesoscale dynamics have on the populations of marine organisms.
Before starting his PhD, Luke completed his Bsc (Honours) at Murdoch University in Western Australia where he studied the relationship between neuston assemblages (e.g., fish and lobster larvae) and regional and mesoscale oceanography. He also has experience working in the Indian Ocean as part of the second International Indian Ocean Expedition (IIOE-2).
Welcome to the lab Luke!
Professor Moninya Roughan has published an article in the Conversation on the unusually warm global oceans this month. She explains how the triple La Nina is over, meaning we are likely to see El Nino develop enabling warmer temperatures. This El Nino-Southern Oscillation cycle is occuring amid the constant rise in temperature associated with anthropogenic climate change, and is the reason why the Pacific Ocean is abnormally warm.
You can read the Conversation article here.
Professor Roughan has also given four interviews on the recent warm waters off New South Wales. She has spoken to 2GB, ABC National Drive, ABC NSW North East, and ABC NSW South East, and introduced the Integrated Marine Observing System (IMOS) and its role in understanding ocean temperatures.
New technician, Zac Anderson, started his position this month. Zac will be involved with maintenance of the NSW-IMOS moored scientific arrays, including setup, deployment and recovery of oceanographic instrumentation (ADCP, Seabird CTDs, Aquatech PTs, acoustic releases etc.), as well as data processing, data quality control and data management.
He previously worked for five years as a Physical Oceanography Research Technician for the Bermuda Atlantic Time-series Study (BATS), where he was often chief scientist on research cruises and was responsible for processing and releasing quality-controlled CTD data.
The IMOS Quality Assurance and Quality Control summit was held for the first time in person since 2019 at the Sydney Institute of Marine Science between March 27-29. Technicians, researchers, and leaders from multiple IMOS mooring nodes met to discuss topics such as mooring data products, mooring configurations, quality control procedures, and the IMOS toolbox.
Moninya, Stuart, Tim and Michael attended the summit. Moninya and Michael gave an update on mooring data collection, data products, and a new automatically-generated report, while Tim provided training of the MATLAB toolbox.
Summit attendees on day 1 (left), and on day 2 (right).
IMOS colleagues were acknowledged for 10+ years of service at the summit, including lab members Tim and Stuart. On March 29th, Moninya, Tim and Stuart also attended a UNSW-organised event to celebrate 10+ years of service at UNSW. Over the years Moninya has led the NSW-IMOS node and the Coastal and Regional Oceanography Lab, playing an integral part in areas such as research, management, and teaching (to name a few). Tim and Stuart have been key in collecting ocean data off NSW through active participation in glider/mooring planning, recoveries and deployments. Thank you for your contributions over the years!

Lab members met at Coogee for a BBQ to bid Taku and his family farewell after 6 months at UNSW. Taku has been collaborating with lab members to investigate EAC characteristics and dynamics using glider and mooring observations. Taku has now returned back to the Japan Sea National Research Institute where he Will continue to collaborate with the lab remotely.
A typical Australian BBQ was ideal for celebrating his contribution over the last 6 months!
BluebottleWatch, led by Amandine Schaeffer, was on display during the Ocean Lovers Festival at Bondi beach.
Primary and high-school students, as well as the general public, were able to learn more about the bluebottle's handedness (see BluebottleWatch webpage for more details), observe how 3D-printed bluebottle models in a tank move in response to wind forcing, and discover how they can use the citizen science project to record their encounter with bluebottles. We hope to see your bluebottles photos there soon!

Neil was asked to join ABC South East NSW Breakfast again a few weeks later to speak about the ongoing high temperatures off the south coast and the recent glider deployment between Sydney and Batemans Bay.
The interview is available here at around the 38 min mark.
New postdoctoral researcher, Dr. Véronique Lago, started her research position this month. Véronique is working on the Fish-SOOP program in collaboration with the fishing industry to put Moana temperature sensors on fishing equipments. Prior to this position, Véronique worked as a post-doctoral scientist at the Climate Change Research Centre at the UNSW looking at the effect of the newest estimates in Antarctic ice sheet melting on the Antarctic Bottom Water formation.
Welcome to the lab!
Lab leader Prof. Moninya Roughan attended the AGU Fall Meeting 2022 in Chicago last week. She presented one oral presentation on the drivers of ocean warming in southern hemisphere western boundary currents (work led by lab member Junde Li), and two posters: one on marine heat waves and their drivers in the Tasman Sea (work led by lab member Yustina Elzahaby), and one on the dynamics of eddies and their role in ocean warming in the East Australia Current.

Lab member Dr. Amandine Schaeffer, who is leading the BluebottleWatch project, along with Surf Life Saving Australia researcher Dr. Jaz Lawes, are developing an online tool that will warn beachgoers about the likelihood of bluebottles invading the beach. This will hopefully reduce the number of stings treated by surf lifesavers, which presently is more than 40,000 around Australia every year.
A 'bloom' of bluebottles swept onshore NSW beaches in 2021 associated with north-easterly winds, and large numbers of beachgoers were stung as a result. 'North-east is the most favourable wind condition for bluebottle beachings at Coogee and Maroubra, while it is dominantly south and south-east for Clovelly,' Dr. Lawes said when speaking to the Sydney Morning Herald.
Dr. Schaeffer and Dr. Lawes encourage citizen scientists to document future beachings at the iNaturalist website.
More details are available in the Sydney Morning Herald article.

Prof. Moninya Roughan, Dr. Amandine Schaeffer, Dr. Shane Keating, and Dr. Colette Kerry were successful in receiving $693,000 in the latest round of ARC Discovery grants for 'Understanding multi-scale dynamics of eddies in the East Australian Current'. This project aims to provide the first rigorous quantification of the dynamics of rotating eddies (the weather systems of the ocean) and fronts on scales ranging from metres to hundreds of kilometres and hours to weeks in the East Australian Current System. This project will improve ocean forecasting and the sustainable management of Australian marine industries and the seafood sector.

Planned 2023 cruise track underneath the SWOT swath.
Group leader professor Moninya Roughan was interviewed by The Sydney Morning Herald to give some thoughts on ocean temperature change, particularly why the ocean was colder at this time of the year.
Long term sea temperatures have been increasing over the last 80 years and the oceans off south-east Australia are warming at the fastest rate on the planet, Moninya stated.
But this month the ocean is one degree colder than average as response of a cold core eddy from Forster to Jervis Bay, controlling the ocean circulation and temperature.
Figure: SST anomaly showing a cold core cyclone pushing cold water to the north.
Dr. Colette Kerry, a postdoctoral research associate member of the Coastal and Regional Oceanography Lab gave an interview for The 60 minutes program to draw on her knowledge and expertise in physical oceanography, to analyse the currents at the moment of the missing of the Belgian backpacker Theo Hayez.
You can watch the full video on The 60 Minutes website. And you can find her interview in part five, minute 1:41, explaining that there was a notorious rip current next to the headland and the East Australian Current (EAC) was unusually close to the shore on the night Theo disappeared.
The Coastal and Regional Oceanography Lab were joined by CSIRO colleagues Dr. Peter Oke, Dr. Tatiana Rykova, and Dr. David Griffin, and visiting colleague Dr. Taku Wagawa from the Japan Sea National Research Institute in Lennox Head to discuss research into the EAC and its eddies.
Presentations were given, literature were discussed, writing was commenced, and even a few card games were played. This was also a great opportunity for lab members to meet in person at a beautiful location on the NSW coast.
Research published in Nature Climate Change led by Junde Li and including team members Moninya Roughan and Colette Kerry has revealed the link between poleward shifting southern hemisphere WBCs and changes in mid-latitude easterly winds. They show that the WBCs have penetrated poleward but have not strengthened, and are now transporting more heat into their extensions.
A writeup of this study was published in The Conversation and was featured in another Nature article.
The team have a research cruise planned for September next year aboard RV Investigator, Australia's research vessel, to explore eddies further. This will shed new light on eddy processes in the warming ocean.

Prof. Moninya Roughan, and team members Michael Hemming and Daniel Lee presented their work this month at the Australian Marine Society Association (AMSA) 2022 conference in Cairns, Australia.
Moninya gave an oral presentation on the spatial and temporal variability of marine heatwaves in key fishing grounds around New Zealand, and presented a poster on the impacts of marine stingers on the Australian community. Daniel Lee presented the drifting dynamics of Bluebottles, as well as introducing a new Bluebottle python module. Michael presented glider data collected during a marine heatwave, and the development and usage of FAIR temperature data products at the national reference stations.
Principle Investigator Dr Amandine Schaeffer has completed another successful voyage on the RV Investigator. The main aim of the voyage was to retrieve the deep East Australian Current mooring array, but time was also spent chasing frontal processes and investigating an unobserved submerged canyon.
Two new PhD students start their EAC research journeys at the lab this month.
Connor Henderson will be investigating the mechanisms behind eddy tilting and how they interact with the EAC and the shelf, while Fernando Sobral will be investigating the heat transport driven by eddies along the EAC system from observational data and modelling outputs.
Welcome to the lab!
Surfing and sailing legend Tim Austin this year celebrates 10 years working at the Coastal and Regional Oceanography lab. Tim joined the lab in March 2012 and has been a valuable part of the Moorings team.
His continued dedication to the team and sustained data collection over the years has enabled a vast range of studies on the EAC and its impact on coastal waters off NSW. Thank you Tim!
PhD student Youstina Elzahaby's work, and professional journey from actuary to marine heatwave expert was recently profiled by the Moana project. Her latest work on the effect of surface mixed layer depth on marine heatwave classification has just been published in Frontiers of Marine Science, and can be found here.
Anomalous rainfall over NSW and QLD coastal areas has caused severe flooding and led to increased river plume discharge as seen by satellite. This increased rainfall coincides with a La Nina, and warmer than average western Pacific ocean surface temperatures.
Team members Dr Junde Li, Prof Moninya Roughan, and Dr Colette Kerry have recently published a study on how mesoscale circulation impacts the structure of river plumes during intense rainfall events.

A Marine Heatwave (MHW) off Sydney has generated media interest in Oceanography with Professor Roughan being interviewed by several mastheads including SMH and The Guardian.
The Guardian - Extreme marine heatwave: waters off Sydney set to break January temperature records
SMH - Sea temperatures inch towards record high but marine ecosystems could suffer
The Independent - Sydney faces extreme marine heatwave
9 News - Marine heatwave sends NSW ocean temperatures soaring to levels not seen in decades
ABC - Extreme marine heatwave sees east coast water temperatures rise
UNSW Oceanography deployed a Slocum research glider to observe the MHW and a picture of the data is shown below. Note the extremely warm pool of surface water shown after 02/02. A CTD cast taken on 3/2/22 shows how the Temperature and Salinity change with depth and the ranges are remarkable.This deployment was carried out in cooperation with Australian National Facility for Ocean Gliders (ANFOG) and supported by Australia's Integrated Marine Observing System (IMOS).

Dr Shane Keating was interviewed as part of a BBC News Item on a surfboard which had travelled over 2500km before being reunited with its owner nearly 2 years later.
Dr Neil Malan's research published in GRL was featured on a number of news sites. This study looked at ocean warming throughout the EAC based on 10 years of Australia's Integrated Marine Observing System (IMOS) Mooring Data. IMOS is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent.

As part of it's commitment to open research and data, three new datasets of model and reanalysis output of the EAC region off the coast of Eastern Australia have been published by UNSW Oceanography. These include a 22-year, free-running, hydrodynamic simulation of the East Australia Current System using the Regional Ocean Modelling System with a horizontal resolution of 2.5-6 km in the cross-shore direction and 5 km in the alongshore direction, and 30 vertical s-levels. The second dataset is a high-resolution reanalysis of the East Australian Current System assimilating an unprecedented observational data set using 4D-Var data assimilation over a 2012-2013. Finally, a high-resolution (750m) free-running hydrodynamic simulation of the Hawkesbury Shelf region off Southeastern Australia using the Regional Ocean Modeling System over 2012-2013 is also available. Further information about all three datasets including download links, license and how-to-cite can be found via the links below.
The recurrent dipole eddies seen associated with the EAC separation is something that's been on our mind for some time, and in Autumn 2017 members of our lab on a research cruise aboard the RV/Investigator made a quick dash across one of these eddy dipole structures, taking measurements between the two eddy centres. In a paper led by Neil Malan, and recently published in JGR Oceans, we combined these detailed shipboard measurements with data from satellite altimetry, drifting buoys, and our 10 years of sustained glider observations.
What did we find?
Well, these dipoles occur a lot more often than we thought (like 50% of time), and they squirt a lot (like an amount half of the average transport of the EAC) of offshore water at high speed onto the shelf, with this water being detected near the coast by our gliders in water as shallow as 50m. Itseems that this jet of water, dubbed the 'larval superhighway', provides a good explanation for why lobster larvae settle along the coast where they do (work by Paulina). We believe it may be important for other species too, watch this space!

The HF RADAR system installed off Newcastle late last year is now working well, as demonstrated by this map for 3 March 2018, in which the radar currents are overlain on a Sea Surface Temperature image as well as geostrophic currents from altimetry. All three ocean observing systems reveal the main flow of the East Australian Current separating from the shelf and heading off towards New Zealand. Only the radar and the SST imagery, however, can resolve the details of the submesoscale eddies between the EAC and the continental shelf. The radar system was installed by SIMS and IMOS and supported by the NSW Government.

Members of the Coastal and Regional Oceanography Lab recently participated in the research voyage �The whole enchilada: from production to predation in Tasman Sea ecosystems,� which focused on the relationship between open ocean production and coastal fisheries off the eastern coast of Australia. They lead the Blue Team onboard the R/V Investigator, identifying different water masses to sample in, and tracking ocean circulation features, from fronts to eddies. During the cruise, several interesting physical features were observed, including: a frontal convergence of two water masses, a train of frontal eddies along the inshore edge of the EAC, and internal waves hundreds of meters below the surface, with waveheights over 50 m!
Figures show Voyage Schematic and a Langrangian Drifter Experiment (Click to enlarge).

Over 8 Million Tons of plastic enter the ocean every year. Plastic bags and packaging strangle and suffocate turtles, seals and seabirds such as the Australian Albatross who become entangled or mistake them for food.
Plastics break down over time into smaller pieces which are eaten by fish and other marine organisms.
Very small plastic pieces (microplastics) may not be visible to the naked eye but are still ingested by zooplankton and small fish harming the entire marine food web through bioaccumalation of toxic substances which are passed onto larger predators (including humans).
How can you help?
REDUCE.. REUSE.. RECYCLE.. RECOVER.. REDESIGN
It is critical we reduce the amount of plastics entering our oceans through dumping or entering waterways.
This starts with reducing your own individual usage and spreading the word to help friends and others reduce theirs too. Dont think your contribution is not important!

World Oceans Day - Free public lecture @ Sydney Institute of Marine Science - 7pm, Thursday 8 June 2017
This months Journal of the Geophysical Research: Oceans edition featured the Coffs Harbour HF Coastal Radar Array front cover along with UNSW Oceanographys latest paper on frontal eddies:
Characterizing frontal eddies along the East Australian Current from HF radar observations by Amandine Schaeffer, A. Gramoulle, M. Roughan and A. Mantovanelli.
Key Points:
Cyclonic eddies occur frequently along the East Australian Current (30�S) on average every 7 days over a 12 month period
Frontal eddies with high Rossby number (0.6�1.9) and inshore radius ~10 km propagate downstream all year round at 0.3�0.4 m/s
Cyclonic frontal eddies influence biology through vertical uplift favoring local production or entrainment of productive water over 100s of km
Amandine and Moninya's recently published GRL paper "Sub-surface intensification of marine heatwaves off southeastern Australia: the role of stratification and local winds" made front page news in the The Sun Herald today.
The Herald Article "Endless Summer" highlighted the threat of marine heatwaves to marine organisms and the importance of long term sub-surface temperature records.
The Port Hacking National Reference Station will turn 75 this year (data pictured) making it one of the longest sub-surface temperature records anywhere. The introduction of the Port Hacking 100m IMOS Mooring in 2009 has significantly enhanced the data resolution.

The 5th UNSW/CSIRO East Australian Current Workshop was hosted by MetOcean solutions in New Zealand. It was an opportunity for students and scientists from UNSW to share their research and foster new collaborations. Themes of the conference included meso-scale ocean circulation and oceanic eddies, as well as operational oceanography.
An Acoustic Doppler Current Profiler (ADCP) which is normally moored in 100m of water off Bondi Beach broke its mooring in January this year and went missing. Luckily it washed up in New Zealand last week and was found by a Foxton fisherman, Rusty Kuiti, while out fishing on Waitarere Beach, NZ.
Rusty contacted us here in Sydney via Clive at OFS and Stuart's father in New Zealand was able to collect it on the weekend. It will be shipped back to Sydney in the next week. Oceanographers here at UNSW are keen to download the data onboard to see what details we can find about its interesting voyage. We are very grateful to Rusty for finding and returning it and relieved to get our research instrument back safely. Rusty was happy with a case of beer as a small reward and said he was heading back down the beach to look for another one.
ADCP's work by sending out 4 sonar 'pings' of sound waves at a set frequency. From the return echo the speed of the water can be calculated throughout the water column. This is similar to how a police radar gun works but instead of tracking one car, an ADCP can track many water parcels in any direction. In addition, this instrument array collects temperature and pressure data and is usually paired with a thermistor string for temperature profiling and water quality or flourescence, salinity, turbidity meters at some sites. These scientific moored arrays are deployed as part of Australia�s Integrated Marine Observing System (IMOS).

Record sea surface temperatures have been observed during the 2015-16 El Nino. This has lead to widespread coral bleaching across Northern Australia and the Great Barrier Reef as coral cells lose their symbiotic algae to heatstress. Initial surveys suggest 93% of the Great Barrier Reef has been affected.

With El Nino declining, it is likely that most Corals in Sydney Harbour will recover from this bleaching episode once temperatures return to normal. However, this disquieting event should reinforce calls for a marine park to be established in Sydney Harbour to protect her unique diversity as combinations of stressors such as heatstress, pollution and overfishing can cause sudden and irreversible change to an ecosystem.

A national marine science plan covering the next 10 years was released yesterday by the Australian Government. This plan calls for increased seatime for RV Investigator, systematic mapping of Australias marine environment and co-ordination of existing marine scence efforts in particular a "national oceanographic modelling system". According to National Marine Science Committee Chairman, Mr John Gunn only 25% of Australias marine environment is comprehensively mapped. The plan also calls for more spending on Marine Science, currently less than 1% of marine revenue and for graduate training to become more multidisciplinary. Marine scientists need to be across social sciences, economics, maths, statistics, physics, chemistry and information technology — along with emerging fields such as bioinformatics and new “omics” disciplines including metagenomics, proteomics and metabolomics.

Groundbreaking oceanograpic insights into fish larvae and small eddies as reported in the Coffs Coast Advocate today by the team from our UNSW Coastal and Regional Oceanographic Laboratory. Some more information on fish larvae and audio of an interview with Professor Iain Suthers here at ABC Rural.
Oceanographers: Moninya Roughan, Paulina Cetina-Herida, Shane Keating, Amandine Schaeffer, Carlos Rocha.
Australia's new ocean-going research vessel Investigator has discovered extinct volcanoes likely to be 50 million years old about 250 kilometres off the coast of Sydney. The chief scientist for the voyage, UNSW Australia marine biologist Professor Iain Suthers, said that while searching for the nursery grounds for larval lobsters the ship was also routinely mapping the seafloor when the volcanoes were discovered in 4,900 metres of water. "The voyage was enormously successful. Not only did we discover a cluster of volcanoes on Sydney's doorstep, we were amazed to find that an eddy off Sydney was a hotspot for lobster larvae at a time of the year when we were not expecting them," Professor Suthers said.
The four extinct volcanoes in the cluster are calderas, which form after a volcano erupts and the land around them collapses, forming a crater. The largest is 1.5 kilometres across the rim and it rises 700 metres from the sea floor. Professor Richard Arculus from the Australian National University, an igneous petrologist and a world-leading expert on volcanoes, said these particular types of volcanoes are really important to geoscientists because they are like windows into the seafloor. "They tell us part of the story of how New Zealand and Australia separated around 40-80 million years ago and they'll now help scientists target future exploration of the sea floor to unlock the secrets of the Earth's crust," Professor Arculus said. "They haven't been found before now because the sonar on the previous Marine National Facility (MNF) research vessel, Southern Surveyor, could only map the sea floor to 3,000 metres, which left half of Australia's ocean territory out of reach." "On board the new MNF vessel, Investigator, we have sonar that can map the sea floor to any depth, so all of Australia's vast ocean territory is now within reach, and that is enormously exciting," Professor Arculus said.
Professor Suthers said the 94-metre Investigator has other capabilities that marine scientists in Australia have never had before, and the vessel will be key to unlocking the secrets of the oceans around our continent and beyond. "Investigator is able to send and receive data while we're at sea, which meant the team back on base at UNSW in Sydney could analyse the information we were collecting at sea and send back their analysis, along with satellite imagery, so we could chase the eddies as they formed," Professor Suthers said. "This is the first time we�ve been able to respond directly to the changing dynamics of the ocean and, for a biological oceanographer like me, it doesn't get more thrilling," Professor Suthers said. "It was astounding to find juvenile commercial fish species like bream and tailor 150 kilometres offshore, as we had thought that once they were swept out to sea that was end of them. But in fact these eddies are nursery grounds along the east coast of Australia." The research voyage led by Professor Iain Suthers departed Brisbane on 3 June and concluded on 18 June in Sydney, with 28 scientists from UNSW, La Trobe University, the University of British Columbia, the University of Sydney, the University of Auckland, the University of Technology Sydney, and Southern Cross University.
The centre of the volcanic cluster is shown on the map below, 248 kilometres from Sydney Heads. The cluster is 20 kilometres long and six kilometres wide and the seafloor is 4890 metres deep, with the highest point in the cluster rising up to 3,998 metres.

A/Prof Moninya Roughan and 4 other researchers from UNSW Oceanography are aboard RV Investigator to study eddy evolution and the physical oceanography of the East Australian Current Coastal Ocean Region. They are part of a expedition led by Prof. Iain Suthers investigating the biology, chemistry and dynamics of submesoscale frontal eddies (aka Freddies).
There is a nice write-up of this Expedition to study offshore eddies on UNSW Newsroom
The shiptrack and near realtime data (example below) can now be viewed on the IMOS Oceancurrent website as described here.
5 members of UNSW Oceanography headed out to sea today aboard RV Investigator to assist in a scientific expedition to deploy a deepwater mooring array which will monitor the East Australian Current at approximately the latitude of Brisbane. 6 moorings are to be deployed in depths of almost 5000m. These moorings house scientific instruments which will measure water properties such as temperature and salinity and also water velocity from the ocean floor to the surface. This will allow unprecedented unserstanding of the temporal variability of the East Australian Current critical to accurate modelling of the Australian coastal ocean region and also to inform global ocean and climate models. Very little is known about the long term variability of the East Australian Current although recent recearch has suggested an increase in both strength and southward penetration.
In addition to the mooring deployment there will be a number of other concurrent research activities during this voyage. These include water sampling and hydrochemical analysis, acoustic current profiling, biological surveying and a XBT (expendable bathythermograph) calibration study.

Following a successful trial deployment, the Sydney Harbour Marine Observatory (SHMO) Realtime Buoy has been serviced and redeployed. The buoy is located approximately 0.4nm south of the Sow and Pigs Reef in the middle of Sydney Harbour. It is between the western and eastern channels in approximately 17m of water and in the proximity of Chowder Bay. Data from the buoy is streaming live to UNSW servers and will be available to view on the web in near realtime. Surface (1m) Temperature and Salinity can now be viewed here.
Subsea capabilities are in advanced development and will include Dissolved Oxygen, FLNTU, Seafloor Salinity, Temperature and Current profiling sensors. Data will be streamed back via underwater modem and broadcast in near realtime. The strength of this system is that adaptive and remote adjustable sampling will now be possible. For example, during anomolous conditions, sampling frequency and burst rate can automatically adapt to maintain a required standard deviation, or an instuments sampling regime can be remotely tasked.

Applied Mathematics in HF Radar Oceanography : Some Recent Developments Abstract:
It is a common feature among remote sensing technologies that very considerable progress can be made with relatively simple physical and mathematical models. This is often fortuitous, as without getting �runs on the board� at an early stage, support for further development may evaporate and consign a technology to the graveyard of good-in-principle ideas. But, having survived to puberty, it is equally common for progress to slow or even stall because the detail and fidelity of measurements fail to meet the rising expectations of the users. At this point there is no option but to identify the factors that are limiting performance and to develop techniques to mitigate them. Typically the research problems which arise at this point demand a marriage, or even a m�nage-a-trois, between the disciplines of physics, engineering and mathematics. In the case of HF radar in its oceanographic roles, several topics within the realm of applied mathematics are of special interest at present, and it so happens that these are strongly represented in the research activities of the Department of Applied Mathematics at UNSW, specifically in the areas of (i) fluid dynamics, oceanic and atmospheric sciences, (ii) nonlinear phenomena, (iii) inverse problems, (iv) optimisation, and (v) computational mathematics. In this talk I shall illustrate the application of these branches of mathematics to the problems currently of concern to the HF radar community.

Congratulations to Moninya on receiving the great honour of being selected by the Chinese 'Recruitment Program of High-end Foreign Experts of the State Administration of Foreign Experts Affairs' to receive a fellowship to spend time in Shanghai, China as a 'High-end Foreign Expert'. The generous fellowship will allow Moninya to spend up to 6 months in Shanghai over the next 3 years, based at the 'State Key Lab' in Estuarine and Coastal Science at Eastern China Normal University.
State Key labs are recognised as the leading institutes in a discipline, somewhat similar to Australia's Centre's of Excellence, and receive continuing funding.
Moninya will also be spending time at SunYat-sen University in Guangzhou (top 10 in China), and possibly the Ocean University of China, Qingdao during this time. ECNU and OUC are partner Institutes in one of the flagship programs at Sydney Institute of Marine Science (SIMS), the World Harbour Project, led by Peter Steinberg. We wish Moninya all the best in this fellowship and look forward to hearing of new collaborations between China and Australia.
Neil Oliver and the Coast Australia documentary filming team came along on a Slocum glider deployment offshore from Yamba. They were filming for episode 3 of the second series entitled Northern NSW. The team filmed the glider deployment and were lucky enough to see some Humpback whales cruising up the coast. The show will be aired tonight on the History Channel and should appear on SBS sometime later this year.

Amandine recently took part in the oceanographic campaign aboard the L�Astrolabe to Antartica. She took temperature profiles using XBTs (Expendable BathyThermograph) during the voyage from Hobart to Terre Adelie and back. The program SURVOSTRAL (SURVeillance of the Ocean auSTRAL) has been collecting temperature and subsurface salinity measurements (from a thermosalinograph) in the Southern Ocean since 1992. Research investigations include water mass fronts, seasonal and interannual variability of the heat budget, transport of the Antarctic Circumpolar Current and long term trends of the Southern Ocean warming. The data is available on the IMOS portal and plots can be found here with thanks to the Scripps High Resolution XBT Program.

A symposium will be held next week, Tuesday, 18 June 2013 9am-4pm, at UNSW hosted by Sci. Prof, Trevor McDougall and Dr Moninya Roughan. Current research will be showcased by Ocean scientists and students of the School of Mathematics, Faculty of Science, UNSW.
A Slocum Glider codenamed 'Nemo' was recovered off Narooma a week ago by Dr Robin Robertson and her team. An article in the Narooma News (link below) discusses the recovery and the two Batesman Marine Park moorings operated by the Coastal and Regional Oceanography Lab at UNSW.
See the original article in the Narooma News.
Near real time glider data can be accessed through Australian National Facility for Ocean Gliders site.
As part of a television item regarding the voyage of 'Papa Mau' Dr Moninya Roughan was interviewed about the scientific capabilities of the Liquid Robotics Wave Glider and its potential for applications here.
See the footage on SBS website here or here.
Representatives from the University of New South Wales (UNSW) Oceanographic Department will take part in celebrations to mark the arrival of 'Papa Mau' to Australia following a historic and record breaking 9000 nautical mile (16668 km) voyage across the Pacific. During its voyage the Wave Glider collected a large amount of data which Liquid Robotics are providing as open access. Congratulations to Liquid Robtics and 'Papa Mau'!
See the Press Release from Liquid Robotics here
The first Wave Glider (and indeed Vessel) ever to cross the Pacific unassisted arrived in Australia today and was recovered off Bundaberg in 2-3m seas. This marks the end of a historic voyage and the longest ever conducted by a robotic vehicle anywhere. The Wave Glider built by Liquid Robotics based in California has travelled solo across the Pacific using Wave Power for Propulsion and Solar Power for its Scientific Instruments. Liquid Robotics were assisted by Underwater Video Systems based in Newcastle in the retrieval off the Glider near Hervey Bay. It is truly a great achievement and perhaps the beginning of a new era for Ocean Observing Systems and Oceanography.
This is expected to be the first in a series of national workshops that, over time, will contribute to the co-evolution of an integrated national marine observing and modelling capability for Australia that is appropriate to our status as a ‘marine nation’.
This meeting will primarily be focused on ocean to coastal modeling; but we will introduce issues around biogeochemical and near shore modeling.
The Australian Coastal and Oceans Modelling and Observations Workshop (ACOMO) 2012 is organised by IMOS (Integrated Marine Observing System). The School of Mathematics and Statistics, UNSW is one of the sponsors of the workshop, and Dr Moninya Roughan is a member of the Organising Committee.
