Project Total: $493,750; The project will host a ACCESS-NRI software engineer at UTAS/IMAS to enhance Australia's capabilities in coupled ice sheet and Earth system modelling. The key objective is to develop and integrate a new coupled ice sheet-ocean model using the Ice Sheet System Model (ISSM) and the Australian Community Climate and Earth System Simulator Ocean Model version 3 (ACCESS-OM3). This advanced model will facilitate a thorough analysis of the interactions between ice sheets, sea ice, and the ocean, thus advancing predictive climate modelling. The project will contribute to global understanding of cryosphere dynamics and improve the accuracy of projections related to sea-level rise and climate change. Additionally, this initiative will bolster collaboration within the Australian research community and position IMAS/UTAS as a prominent contributor to both national and international climate science efforts. Funded by: ACCESS-NRI - Grant ($493,751); University of Tasmania.

Project Total: $460,183; This project aims to understand what controls the transport of heat polewards to the Antarctic margin. This heat transport determines the rate at which ice shelves melt, and thereby controls the Antarctic contribution to sea level rise. Expected outcomes of this research include a tool for near-real-time estimation of the Antarctic overturning circulation and accurate projections of future ocean heat transport in a changing climate. The project will provide a step-change in our understanding of the Southern Ocean. The results will provide vital information for policy makers and the general public on the future of this crucial region and its impact on Australian and global climate, sea level rise, and Antarctic sea ice.

Project Total: $25,000; This project will deliver an Antarctic climate change overview report that covers the current and projected broad risk to Antarctica from climate change, capturing classes of risk in a descriptive way. Funded by: Bureau of Meteorology - Tender ($25,000); University of Tasmania.

Project Total: $404,000; This project will adress our lack of confidence in future projections of sea ice around Antarctica by elucidating the mechanisms controlling sea ice in the Southern Ocean. There is low confidence is current sea ice projections, limiting our ability to predict ice shelf melt and sea level rise. This project will lead to a detailed understanding of the future of sea ice in the Southern Ocean, improving our understanding of ocean dynamics, ice shelf melt, and sea level rise. The results from this project will enhance projections of sea ice, and therefore also ice shelf melt and sea level rise. Improved sea level projections will aid policy decisions for coastal communities. Funded by: Australian Research Council - Grant-Discovery Projects ($404,000); University of Tasmania ($115,424).
