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.
Antarctic sea ice

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.
McMurdo Sound pack ice

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.

Basal mass balance and prevalence of ice tongues in the Western ross sea

Authors: R.Gomez-Fell, O.Marsh, W.Rack, C.Wild, H.Purdie
Year Published: 2023
Document Type: Papers
Ownership: Frontiers in Earth Science
Summary: Calculating the basal mass change of twelve Antarctic ice tongues using a flux gate approach, deriving thickness from ICESat-2 height measurements and ice surface velocities from Sentinel-1 feature-tracking over the same period.

Ocean turbulent boundary-layer influence on ice crystal behaviour beneath fast ice in an Antarctic ice shelf water plume: The “dirty ice”

Authors: C.Stevens, N.Robinson, G.O'Connor, B.Grant
Year Published: 2023
Document Type: Papers
Ownership: Frontiers in Marine Science
Summary: Observations of ocean boundary-layer processes and ice crystal behaviour in an Ice Shelf Water outflow region from the Ross/McMurdo Ice Shelves.

Crevasse refreezing and signatures of retreat observed at Kamb Ice Stream grounding zone

Authors: J.Lawrence, P.Washam, C.Stevens, C.Hulbe, H.Horgan, G.Dunbar et al.
Year Published: 2023
Document Type: Papers
Ownership: Nature Geoscience
Summary: In situ observations from an underwater vehicle deployed at Kamb that show how fine-scale variability in ice and ocean structure combine to influence a diversity of ice–ocean interactions.
Antarctic Sea Ice 01 Physical Role

Antarctic Sea Ice #1: Physical role and function

Authors: Kyle Clem, Rob Massom, Sharon Stammerjohn and Phillip Reid
Year Published: 2022
Document Type: Reports
Ownership: Scientific Committee on Antarctic Research
Summary: Sea ice – comprising frozen seawater in the form of both moving pack ice and stationary coastal landfast ice (fast ice) – is of major climatic, ecological and societal importance. This summary on SCAR's Environments Portal is based on the best available science.
