Case study: Detecting polynya from space

Year Published: 2023
Document Type: Case Studies
Ownership: Antarctic Science Platform
Summary: Antarctic Science Platform researchers are using satellite data to determine the spatial extent of polynya with better accuracy, which unlocks the ability to quantify their role in large-scale processes, such as sea-ice formation, ocean circulation and their impact on marine ecosystems.

Conservation of heat and mass in P-SKRIPS version 1: the coupled atmosphere–ice–ocean model of the Ross Sea

Authors: A.Malyarenko, A.Gossart, R.Sun, M.Krapp
Year Published: 2023
Document Type: Papers
Ownership: Geoscientific Model Development
Summary: A coupled model for the Ross Sea, P-SKRIPS, that conserves heat and mass between the ocean and sea ice model (MITgcm) and the atmosphere model (PWRF).
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.

Delineating Polynya Area Using Active and Passive Microwave Sensors for the Western Ross Sea Sector of Antarctica

Authors: G.Burada, A.McDonald, J.Renwick, B.Jolly
Year Published: 2023
Document Type: Papers
Ownership: Remote Sensing
Summary: 40m scale polynya information over the western Ross Sea from high-resolution Synthetic Aperture Radar (SAR) Sentinel-1 C-band data.
Emperors and their chicks

Survival of emperor penguins depends on emissions reductions

Authors: Rowan Howard-Williams and Michelle LaRue
Year Published: 2022
Document Type: Cold Call Articles
Ownership: Antarctic Science Platform
Summary: Emperor penguins are an iconic Antarctic species, but their dependence on sea ice means they are expected to be impacted substantially by climate change.
