Summary: The world’s ice sheets are sensitive to environmental change and, as the largest reservoir of freshwater on Earth, melting of the Antarctic Ice Sheet has significant potential to raise sea levels and disrupt global ocean circulation. To determine ice sheet response to warming, our team of researchers in the Antarctic Ice Dynamics project are looking at environmental records of how the Antarctic ice sheets and surrounding ocean have changed in the past, and comparing those records to signals of change that we can detect today.

Summary: A changing Antarctica will impact oceanic transport of heat and other associated materials, such as salt, carbon dioxide, oxygen and nutrients. Researchers in the Antarctic Ocean Mechanics project are investigating past and present ocean conditions - currents, polynya formation, sea ice and dispersion of meltwater - and how this may change as the world warms.

Summary: In case you missed it, here are some of the media and outreach opportunities our team was involved in during the past year. There were also public talks, school visits and publications in subscription-based magazines.

Type: Cold Call Article

Authors: Antarctic Science Platform

Summary: This Cold Call contains four articles that explore how sea ice interacts with the climate, ocean and ecosystem functions across regional and global scales, and highlights where Antarctic Science Platform research is investigating these issues.

Summary: Climate models struggle to reproduce observed Antarctic sea-ice behaviour, due to the many processes affecting its formation and melt. Models must get these processes right in order to inform us what might happen next.

Summary: Sea ice plays a crucial role in the life cycles of many Antarctic organisms, from the algae at the base of food chains, to seals and penguins at the top.

Summary: Antarctic sea ice has an annual seasonal cycle of formation and melting, plus it’s exposed to the winds and storms of the Southern Ocean and to a range of climate influences from near and far.
