Monitoring melting of the Ross Ice Shelf using radar
Date: 2024
Type: Science
Summary: Researchers are using custom-built instruments to monitor ice shelf melting in a rapidly melting region of the Ross Ice Shelf, surrounding Ross Island. After a successful 2023/24 Antarctic field season, all instruments are now operational.

SWAIS2C core workshop offers first glimpse of sediment from below Ross Ice Shelf
Date: 2024
Type: Update
Summary: Sediment cores retrieved from Antarctica’s Siple Coast last summer were carefully opened and examined at a recent workshop at the Otago Repository for Core Analysis (ORCA), an important step in the hunt for clues about the past behaviour of the West Antarctic Ice Sheet.

West Antarctica’s ice sheet was smaller thousands of years ago – here’s why this matters today
Date: 2024
Type: Science
Authors: Dan Lowry
Summary: A key uncertainty in how much and how fast the seas will rise lies in whether currently “stable” parts of the West Antarctic Ice Sheet can become “unstable”. It retreated hundreds of kilometres some 7,000 years ago, and then advanced again to its present position within the last 2,000 years. But why? New research published in Nature tests two main hypotheses.
Sea ice

Antarctica's sea ice hit another low this year – understanding how ocean warming is driving the loss is key
Date: 2024
Type: Field Work
Authors: Craig Stevens
Summary: At the end of the southern summer, Antarctica’s sea ice hit its annual minimum. By at least one measure, which tracks the area of ocean that contains at least 15% of sea ice, it was a little above the record low of 2023.

Platelet ice sampling system: the first deployment
Date: 2024
Type: Science
Summary: The 22/23 Antarctic field season was the first scientific deployment of the new platelet sampling system. This custom-designed and bespoke-engineered system successfully sampled the biota associated with sea ice and platelet ice habitats.

Podcast: The sea ice factories of Antarctica
Date: 2024
Type: In the media
Authors: Radio New Zealand: The Detail
Summary: If you want to study the health of the world's oceans, you need to get to their heartbeat. That's deep in the Ross Sea, where the sea ice factories of Antarctica - or polynyas - live.
