<P> The EAC has nutrient poor water, however it does cause upwelling in places along the coast line . The Eddies produced cause an increase in vertical mixing within the Tasman Sea . The process of producing, moving, and destroying eddies causes the thermocline layer to mix with the surface layer, bringing some nutrients up to the surface . The EAC and its eddies frequently flow onto the continental shelf and inshore, influencing circulation patterns and increasing mixing . Eddies aren't the only way the EAC brings nutrients to the surface . Features along the coast push the current further off shore and if there is a strong northerly wind, it will push the current even further off shore, allowing deep water to rise up the coast, bringing nutrients up to the surface . </P> <P> The EAC experiences seasonally variations . It tends to be strongest in the summer, with an amplitude flow around 36.3 Sv . It is its weakest during the winter months flowing at a rate around 27.4 Sv . Over the past 50--60 years the EAC has shifted . The south Tasman Sea has become warmer and saltier from 1944 - 2002 . This has resulted in the current strengthening and extending southward . This shift in the EAC flow past Tasmania is controlled the Southern Hemisphere subtropical ocean circulation . This trend is thought to be caused by changes in wind patterns due to ozone depletion over Australia . There is a strong consensus with climate models that this trend will continue to intensify and accelerate over the next 100 years . The current is predicted to increase greater than 20%, thanks to the increase in South Pacific winds . </P> <P> In the 2003 Disney / Pixar animated film Finding Nemo, the EAC is portrayed as a superhighway that fish and sea turtles use to travel down the east coast of Australia . The characters Marlin and Dory join a group of sea turtles in using the EAC to help them travel to Sydney Harbour . The basic premise of this storyline is correct . Every summer, thousands of fish are swept from the Great Barrier Reef to Sydney Harbour and further south, however, the Current is not nearly as rapid as depicted in the film . </P>
