What is it about?

First, we developed an accurate mapping of the East Australian Current using satellite imagery. Next, using the mapping products, we directly measure and investigate the time‐varying spatial closeness between the EAC and the coast. Our results show that the EAC is a highly dynamic and unstable eddy‐current system which intrudes landward all year round with multiple periods and scales.

Why is it important?

The East Australian Current (EAC) frequently intrudes landward, drives coastal water uplift, and consequently brings nearshore nutrient blooms. Such current intrusions therefore exert significant impacts on the coastal marine ecosystem. In this paper, for the first time a quantitative mapping of a highly dynamic Western Boundary Current system (the EAC) is created using imagery technique on satellite SST data. Direct evidences confirm that the EAC is an unstable eddy‐current system which encroaches onshore with multiple frequencies and amplitudes.


The semiautomatic mapping presented in this paper has many practical applications in measuring, monitoring and tracking of ocean currents and eddies.
