Active Ice-Shelf Rift Systems on the Amery Ice Shelf, East Antarctica. Our work will inform the public on how the Antarctic might contribute to global sea level rise, e.g., are current iceberg production rates accelerating and causing inland ice to flow into the sea more rapidly? Furthermore, a greater understanding of the important Earth systems, including the ocean-ice-atmosphere system, is important to a society contemplating the responsibilities of stewardship of the planet as we move into t ....Active Ice-Shelf Rift Systems on the Amery Ice Shelf, East Antarctica.

Iron in the Antarctic sea ice zone and its role in the past and future climate. The Antarctic sea ice environment has remained poorly investigated for decades as it is difficult to access. Recent scientific advances have revealed that melting sea ice may provide a significant amount of the plant micro-nutrient iron to the Southern Ocean. Given that polar waters are iron-deficient and seasonal sea ice affects ~14 million square kilometres of ocean, the importance of iron fertilisation from deca ....Iron in the Antarctic sea ice zone and its role in the past and future climate. The Antarctic sea ice environment has remained poorly investigated for decades as it is difficult to access. Recent scientific advances have revealed that melting sea ice may provide a significant amount of the plant micro-nutrient iron to the Southern Ocean. Given that polar waters are iron-deficient and seasonal sea ice affects ~14 million square kilometres of ocean, the importance of iron fertilisation from decaying sea ice and its effect on global climate urgently need to be evaluated. This proposal aims at improving our understanding of Earth's complex system, and will inform future climate change policy in Australia.

Summary
Antarctic and Southern Ocean Research. This multidisciplinary proposal has four integrated research themes which enhance existing Antarctic research. The proposal will build new polar research capability in Tasmania to secure and reinforce its recognition as a global leader in Antarctic and Southern Ocean science; develop a marine technology hub; leverage co-investment with national and overseas agencies; and further establish Tasmania as a gateway for Antarctic research, education, innovation a ....Antarctic and Southern Ocean Research. This multidisciplinary proposal has four integrated research themes which enhance existing Antarctic research. The proposal will build new polar research capability in Tasmania to secure and reinforce its recognition as a global leader in Antarctic and Southern Ocean science; develop a marine technology hub; leverage co-investment with national and overseas agencies; and further establish Tasmania as a gateway for Antarctic research, education, innovation and logistics. The initiative will bolster Australia's Antarctic program via integration of novel understanding of ice-shelf and ice sheet contributions to present-day sea level change, and new perspectives on polar marine ecosystems and biogeochemical cycles, and sea-ice forecasting.Read moreRead less
