Towards an integrated understanding of boundary current systems

New South Wales - IMOS

To learn more about our Integrated Marine Observing System or IMOS you can visit imos.org.au or watch this video.


The broad geographical reach of the East Australian Current (EAC) influences the climate and marine economies of nearly half the Australian population, from Brisbane to Sydney, Melbourne, and Hobart. The poleward flowing EAC brings warm water down the New South Wales (NSW) coast modulating the region's climate as well as the composition, organisation and function of marine ecosystems.

The EAC and the eddy field it produces dominate the marine environment on the narrow, NSW continental shelf. The main focus of the NSW node of the Integrated Marine Observing System (IMOS) is on the processes north and south of the separation zone off Coffs Harbour (30ºS) and Sydney (34ºS), with observations at Maria Island (South East Australia IMOS), and at the full depth EAC monitoring mooring off Stradbroke Island (Queensland's IMOS) and Bluewater and Climate IMOS observations also contributing to the understanding of these processes.

The key research aims pertinent to NSW-IMOS are:

In partnership with the Sydney Institute of Marine Science, Australian National Facility for Ocean Gliders and Australian Coastal Ocean Radar Network, the Coastal and Regional Oceanography Group help to maintain and manage NSW-IMOS via our technical team and scientific input.
