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.
Summary: New Zealand’s Antarctic community is invited to participate in the design and development of a second phase of the Antarctic Science Platform.
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.
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.
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.
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.
Summary: Researchers have examined domestic stakeholder perspectives regarding Antarctic knowledge exchange, using Aotearoa New Zealand as a case study
