Sea Ice New edition of the leading resource on the Arctic and Southern Oceans with contributions from the world’s experts on sea ice Sea Ice delivers insights into the very latest understanding of sea ice dynamics, how we measure (and model) its extent, the ecosystems that depend on sea ice, and the effect of climate change on its distribution. The book also discusses how sea ice influences the oceanography of underlying waters and the influence that sea ice has on the world’s climate. This newly revised and updated Fourth Edition looks at ice-based food webs and the impact on global geopolitics as well as changes in human activity in the Arctic. Written by a team of more than 80 of the world’s leading experts from 13 countries, Sea Ice includes information on: Sea ice thickness distribution and snow and surface processes on sea iceThe short-term and long-term dynamics of Arctic versus Antarctic Sea iceCurrent methods of satellite remote sensing of sea iceThe ecology of sea ice, from microbes to mammals to marine birdsThe cycling of contaminants across the ocean-sea ice-atmosphere interface In its new edition, Sea Ice remains the leading multidisciplinary resource on the subject for all policy makers, researchers, and students with an interest in the polar regions and their role in the world’s oceanic systems.

Delighted to announce a new 📖 just out - well at least the online version (print version still a few weeks off)

New #DEACoastlines annual shoreline data for 2024 is now live! 🌊🛰️🎉

2024 was a relatively stable year for coastal change across Australia, with mostly moderate and balanced rates of growth and retreat across our coastline.

Support the Polar Geospatial Survey and their amazing Polar DEM production by taking their survey.

Looking forward to seeing what the sediment team uncover about past changes in the Denman Glacier system.

Offshore to the west of the Denman Glacier, the Kasten core sediment tubes keep on coming - and this one, retrieved from the seafloor this week, is a keeper #DMV

Taryn Noble (@utas.edu.au) leads the research team to examine its many interesting layers ⬇️

Moorings: Sentinels to monitor ocean heat when we’re not there - AAPP Like weather stations for the sea, the Denman Marine Voyage has installed three moorings off the ice shelf to monitor ocean heat

🌊 Like weather stations for the sea, the Denman Marine Voyage #DMV has installed three moorings off the ice shelf in East #Antarctica, to monitor ocean heat for the next few years before we come back to get them.

Great to be able to track Australia’s icebreaker Nuyina from space while it’shard at work off the Shackleton Ice Shelf!

Linda has made such amazing contributions in the field of ancient DNA from Antarctic sediments. Very well-deserved award!
