Resolving the warming East Australian Current's impact on a marine food web. This project aims to understand the effects of climate change on marine food webs, from plankton production to predation by iconic marine fauna, by integrating data on oceanographic conditions and fish distribution with the foraging patterns and breeding success of seabirds. Warming waters due to strengthening western boundary currents have unknown consequences for coastal marine food webs. Innovative prey capture signatures from accelerometers, and advanced movement models from satellite locations will show how predators locate and prey upon fish schools. Anticipated outcomes are insight into how changing resource availability in the oceans affects ecosystem resilience; improved viability for coastal industries; and ecosystem-based conservation management strategies.

解决东澳大利亚海流变暖对海洋食物链的影响。该项目旨在通过将海洋条件和鱼类分布的数据与海鸟的觅食模式和繁殖成功相结合，了解气候变化对海洋食物网的影响，从浮游生物的生产到标志性海洋动物的捕食。由于西部边界流加强而导致的海水变暖对沿海海洋食物网造成了未知的后果。来自加速计的创新猎物捕获信号，以及来自卫星位置的先进运动模型将显示捕食者如何定位和捕食鱼群。预期的成果是洞察海洋中不断变化的资源供应如何影响生态系统的复原力；提高沿海工业的生存能力；以及基于生态系统的养护管理战略。
