The role of Eastern Antarctic polynyas in global ocean circulation. This project aims to study Antarctic polynyas, an important, but poorly observed marine habitat, which profoundly influence the global climate. The major water masses of the world's oceans are formed there, making a large contribution to the ocean heat and carbon dioxide uptake. This study will collect data on ocean properties to 2000m from polynyas in eastern Antarctica throughout the Antarctic winter. The outcomes will be the ....The role of Eastern Antarctic polynyas in global ocean circulation. This project aims to study Antarctic polynyas, an important, but poorly observed marine habitat, which profoundly influence the global climate. The major water masses of the world's oceans are formed there, making a large contribution to the ocean heat and carbon dioxide uptake. This study will collect data on ocean properties to 2000m from polynyas in eastern Antarctica throughout the Antarctic winter. The outcomes will be the provision of data of critical importance to oceanographic and climate studies.Read moreRead less
Resolving the warming East Australian Current's impact on a marine food web. 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 unk ....Resolving the warming East Australian Current's impact on a marine food web. 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.Read moreRead less
