Offshore eddies shed by the East Australian Current can draw in coastal water from the Stockton Bight on the NSW central coast. This area is anecdotally recognized as a fisheries nursery area. It is often enriched by upwelling of cold, nutrient-rich waters which can seed these eddies with larval fish and their food. We will test if such eddies nurture plankton communities and then transport them back to the coast, giving rise to a useful index for predicting future fisheries, as well as explaining biodiversity changes to marine park planners. We will provide a census of these eddies during El Nino-Southern Oscillation events and climate change of the past 15 years in unprecedented detail.

东澳大利亚洋流带来的近海涡流可以从新南威尔士州中部海岸的斯托克顿湾吸引沿岸水。这一地区被公认为渔业苗圃。冰冷、富含营养的海水涌出，可以为这些漩涡提供幼鱼和它们的食物，从而使它变得更加富饶。我们将测试这种漩涡是否会滋养浮游生物群落，然后将它们运回海岸，从而产生一个有用的指数，用于预测未来的渔业，以及向海洋公园规划者解释生物多样性的变化。我们将提供过去15年厄尔尼诺-南方涛动事件和气候变化期间这些涡旋的前所未有的详细统计。
