Drilling Sea ice 2025 IMG 8596 INGA Smith

Why is Antarctic sea ice so hard to model?

Authors: Andrew Pauling, Inga Smith, Max Thomas
Year Published: 2023
Document Type: Cold Call Articles
Ownership: Antarctic Science Platform
Summary: Climate models struggle to reproduce observed Antarctic sea-ice behaviour, due to the many processes affecting its formation and melt. Models must get these processes right in order to inform us what might happen next.

Sea ice and ecosystems

Authors: Rowan Howard-Williams, Ian Hawes
Year Published: 2023
Document Type: Cold Call Articles
Ownership: Antarctic Science Platform
Summary: Sea ice plays a crucial role in the life cycles of many Antarctic organisms, from the algae at the base of food chains, to seals and penguins at the top.

The connections between sea ice and climate

Authors: James Renwick
Year Published: 2023
Document Type: Cold Call Articles
Ownership: Antarctic Science Platform
Summary: Antarctic sea ice has an annual seasonal cycle of formation and melting, plus it’s exposed to the winds and storms of the Southern Ocean and to a range of climate influences from near and far.

Sea ice and ocean circulation

Authors: Rowan Howard-Williams, Denise Fernandez, Craig Stevens
Year Published: 2023
Document Type: Cold Call Articles
Ownership: Antarctic Science Platform
Summary: Formation of Antarctic sea ice affects ocean circulation across the globe. Understanding the mechanisms linking these phenomena is crucially important to understand the impacts of future change in Antarctica.

Climate change and international diplomacy in Antarctica

Authors: Rowan Howard-Williams
Year Published: 2022
Document Type: Cold Call Articles
Ownership: Antarctic Science Platform
Summary: How climate change affects Antarctica is going to influence the speed and severity of changes in New Zealand and the rest of the planet. Climate change is a priority topic in Antarctic governance. Next year the Antarctic Treaty Consultative Meeting has dedicated a day to consider the implementation of recommendations in a landmark climate change report. Those discussions will take place in a unique policy setting, almost as unusual as Antarctica itself, because the continent is ‘governed’ by an international treaty system.

Authors: Antarctic Science Platform
Year Published: 2022
Document Type: Case Studies, Science
Summary: New Zealand is one of 12 original signatories to the Antarctic Treaty (signed in 1959), and these annual international meetings are a key target for the Platform’s research data, findings and new understandings.

Authors: Natasha Gardiner, Neil Gilbert, Daniela Liggett
Year Published: 2022
Document Type: Reports
Ownership: Antarctic Science Platform
Summary: Report of an Antarctic Science Platform Workshop held 3 December 2021 to bring together New Zealand’s Antarctic policy and decision-making community to explore the current state of Antarctic science-policy interactions and identify any potential new or improved ways of working.
