Investigating the controls on the extent of tidewater glaciers. This project aims to improve our ability to model tidewater glaciers. The project will conduct studies of two iconic glacial systems in Alaska: Glacier Bay and Columbia Glacier. These glaciers have recently experienced rapid retreat and contributed to sea level rise. In particular, the Grand Pacific Glacier has retreated 100 kilometres up Glacier Bay, the greatest recorded glacier retreat in the last 200 years. The project will use ....Investigating the controls on the extent of tidewater glaciers. This project aims to improve our ability to model tidewater glaciers. The project will conduct studies of two iconic glacial systems in Alaska: Glacier Bay and Columbia Glacier. These glaciers have recently experienced rapid retreat and contributed to sea level rise. In particular, the Grand Pacific Glacier has retreated 100 kilometres up Glacier Bay, the greatest recorded glacier retreat in the last 200 years. The project will use geomorphic mapping, dating and climate reanalysis to better understand the long term behaviour of these glaciers and the drivers of recent retreat. An expected outcome from the project is a better understanding of the long term behaviour of tidewater glaciers and an improvement in our ability to predict sea level rise from them.Read moreRead less
Empowering next-generation sea-ice models with wave–ice mathematics. Sea ice is a crucial part of the Australian and global climate systems, and the most sensitive indicator of the alarming climate changes in motion. This project aims to deliver a vital component in next-generation sea-ice models, by modelling ocean waves in the ice-covered ocean, and implementing it in the leading large-scale sea-ice model. The waves-in-ice model will be accurate for the range of possible wave–ice conditions, u ....Empowering next-generation sea-ice models with wave–ice mathematics. Sea ice is a crucial part of the Australian and global climate systems, and the most sensitive indicator of the alarming climate changes in motion. This project aims to deliver a vital component in next-generation sea-ice models, by modelling ocean waves in the ice-covered ocean, and implementing it in the leading large-scale sea-ice model. The waves-in-ice model will be accurate for the range of possible wave–ice conditions, using understanding derived from state-of-the-art experimental measurements. Powerful mathematical approximation methods will be developed to generate model efficiency. The outcomes will create a new standard in sea-ice modelling, with significant benefits for sea-ice forecasting and climate studies.Read moreRead less
