NSW-IMOS Oceanography Web Application

The East Australian Current (EAC) influences the climate and marine economies of nearly half the Australian population, from Brisbane to Sydney, Melbourne, and Hobart.


Since 2009, the 2000 km long coastline of New South Wales has been instrumented with a network of moored, remote sensing, and in-situ observing platforms to monitor the EAC and its impact on waters of the highly populated east coast of Australia. This network forms part of the larger national-level Integrated Marine Observing System (IMOS). In particular, more than 40 autonomous gliders have been deployed along the east coast from 29°S to 34°S and two high frequency coastal radar arrays measure surface current velocities.  These complementary observations improve our understanding of the regional ocean dynamics, detecting the core of the EAC, its separation from the coast and the downstream eddy field.

This web application was designed to display characteristics of the East Australian current and local ocean conditions in near real time, by leveraging the vast plethora of data collected by NSW-IMOS. The homepage displays near real time ocean conditions useful for both laymen such as beachgoers and technical audiences who would like a quick visualisation without having to download, clean and plot data. Moreover, additional pages allow the curious audiences to delve further into temperature extremes and climatology, historically.


Such an application will be pivotal to marine biologists and fisheries who would like to investigate physical ocean conditions to explain certain anomalies or features, but lack the tools and/or the skill set to quickly do so.
