New South Wales IMOS (NSW-IMOS)
The oceans off south eastern Australia have a complex circulation structure, especially downstream (south) of the East Australian Current separation zone (~31oS). The separation zone and subsequent eddy field drives the water temperature variability along the coast and influences nutrient upwelling and subsequent algal blooms for over 40% of Australia’s population. The EAC and its eddies are strongly implicated in heat transport along the NSW coast. Both warm core and cold core eddies are strongly linked to fisheries recruitment, local biodiversity and marine park location. The EAC’s eddy field is strongly connected with other regional seas and currents, including dynamics to the south off eastern Tasmania, to the east around Lord Howe Island via the Tasman Front, and the East Auckland Current. The Tasman Sea has the world’s fastest increase in water temperature of any regional sea. Off Port Hacking, south of Sydney is one of Australia’s longest hydrographic monitoring stations (~60 years) and off Bondi Beach we have the longest current records (the ORS, since 1990). It is our goal to investigate the key EAC features while building on historical observations.
