Highlights from sea ice and carbon cycle feedback research 2022/23
Date: 2023
Type: Update
Authors: Project 4
Summary: Sea ice extent, and the exchange of carbon dioxide (CO2) and other gases between the atmosphere and ocean, varies from year to year, influenced by changes in atmospheric and open-ocean conditions. Understanding the difference between seasonal variability and long-term change is key to predicting Antarctica’s influence on the future global climate system. Researchers in the Sea Ice and Carbon Cycle Feedbacks project are analysing variability in sea ice and the carbon cycles in the Ross Sea region and on larger scales, including connections to atmospheric circulation and climate processes across the Southern Ocean and much of the Southern Hemisphere.

Sea ice scientists call for urgent emissions reductions to keep our climate liveable
Date: 2023
Type: Update
Summary: Antarctic scientists concerned about dramatic sea ice retreat have today issued the following statement from the emergency summit in Wellington. They have called for urgent reduction in carbon dioxide emissions to keep the climate within liveable conditions.

SWAIS2C: A search for answers about ice sheet collapse
Date: 2023
Type: Update
Authors: Prof Richard Levy and Ceridwyn Roberts
Summary: The drilling project will be the first-ever attempt to obtain a long sedimentary record from well-below the seafloor in West Antarctica. This is ‘discovery science’ - there remains great uncertainty around the age and nature of what will be recovered.

Steering Group Deputy Chair
Expressions of Interest
Date: 2023
Type: Update
Authors: Antarctic Science Platform
Summary: The Antarctic Science Platform is seeking expressions of interest for a Deputy Chair for the Platform Steering Group. The Deputy Chair will take a governance leadership role in transitioning the Platform to a second tranche of funding which begins on 1 July 2025.

Future sea level rise in Aotearoa and Antarctica
Date: 2023
Type: Update
Authors: Tim Naish
Summary: Among the most visible effects of human-induced global warming are rising seas around the world. What does this mean for Antarctica, and for Aotearoa New Zealand? Here, we provide an overview of recent global and local trends, and the importance of understanding the contribution of the Antarctic Ice Sheet to future sea level rise. Research within the Antarctic Science Platform is improving the accuracy of ice sheet models, reducing uncertainty in future projections, and contributing to sea-level projection tools here, and overseas.
