Cold Call: Edition Six

Date: 2023
Type: Cold Call Article
Authors: Antarctic Science Platform
Summary: This Cold Call contains four articles that explore how sea ice interacts with the climate, ocean and ecosystem functions across regional and global scales, and highlights where Antarctic Science Platform research is investigating these issues.

Why is Antarctic sea ice so hard to model?

Date: 2023
Type: Cold Call Article
Authors: Andrew Pauling, Inga Smith, Max Thomas
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

Date: 2023
Type: Cold Call Article
Authors: Rowan Howard-Williams, Ian Hawes
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

Date: 2023
Type: Cold Call Article
Authors: James Renwick
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

Date: 2023
Type: Cold Call Article
Authors: Rowan Howard-Williams, Denise Fernandez, Craig Stevens
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.
Sea Ice Edge

Changes in the Ross Sea and the future of carbon storage

Date: 2022
Type: Cold Call Article
Authors: Miles Lamare, Vonda Cummings, Ian Hawes and Rowan Howard-Williams
Summary: The Southern Ocean mops up anthropogenic CO2 emissions. But acting as a ‘sink’ for this excess heat and carbon dioxide is having an effect on the ocean and the ecosystems it supports.
