Brave high seas and freezing temperatures with four science leaders on a research mission to a melting glacier in Antarctica.

Earlier this year, Australia’s icebreaker RSV Nuyina completed its first marine science voyage, taking 60 scientists to one of the most unexplored remote parts of our planet.

Unprecedentedly low sea ice allowed the team to approach East Antarctica’s Denman Glacier more closely than ever before. What they found was sobering: warm ocean water flowing beneath the glacier’s ice shelf, hastening its retreat.

Over two months at sea, researchers from a range of disciplines from oceanography, biology, geology, and atmospheric science, worked to uncover how vulnerable this glacier is to warming waters, and how quickly that vulnerability could translate into rising seas.

If the Denman Glacier were to melt entirely, it could raise global sea levels by around 1.5 metres. What does this unfolding drama at the planet’s icy edge tell us about the road ahead? Join this talk to hear from the scientists who went there. Tickets are free, but essential.

The experts
- Professor Delphine Lannuzel is a chemical oceanographer at the Institute for Marine and Antarctic Studies at the University of Tasmania in Hobart, She studies the chemistry of sea ice and how it affects the surrounding ocean environment.
- Professor Jan Strugnell is an evolutionary molecular biologist at James Cook University in Townsville, investigating how Antarctic and deep-sea creatures have adapted and evolved over time, especially in response to changes in Earth’s climate and geography.
- Dr Leonie Suter is a geneticist and environment DNA analyst with the Australian Antarctic Division in Hobart, who uses DNA found in water samples, from the ocean surface to the seafloor, to identify and monitor the biodiversity of marine life in Antarctica.
- Dr Laura Herraiz-Borreguero is a physical oceanographer with CSIRO Environment in Hobart, studying the interaction of the warming ocean with Antarctic ice shelves.
