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.
Weddell seal pups

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.

Phytoclass: A pigment-based chemotaxonomic method to determine the biomass of phytoplankton classes

Authors: A.Hayward, M.Pinkerton, A. Gutierrez-Rodriguez
Year Published: 2023
Document Type: Papers
Ownership: Limnology and Oceanography: Methods
Summary: An alternative chemotaxonomic method that utilizes simulated annealing with a steepest descent algorithm to derive class abundances and pigment-to-Chl a ratios.
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.
Antarctic Sea Ice 02 Biological Importance

Antarctic Sea Ice #2: Biological Importance

Authors: Kyle Clem, Rob Massom, Sharon Stammerjohn and Phillip Reid
Year Published: 2022
Document Type: Reports
Ownership: Scientific Committee on Antarctic Research
Summary: Antarctic sea ice, in the form of immobile coastal “fast ice” and the more extensive moving pack ice supports one of the most extensive and productive ecosystems on Earth and is crucial to the structure and function of Southern Ocean marine ecosystems that are highly attuned to its presence and seasonal rhythms. This summary on SCAR's Antarctic Environments Portal is based on the best available science.
Sampling soils for microbiological analyses in Victoria Valley.

Case Study: Machine learning-assisted meta-analysis of biological research in Antarctica

Authors: Antarctic Science Platform
Year Published: 2022
Document Type: Case Studies, Science
Summary: To understand what Antarctic ecosystems may look like in a warming world, it’s critical to first comprehensively understand the current-day biodiversity and biogeography.
Fish below the platelet layer

Case Study: Bespoke technology is advancing Antarctic research

Authors: Antarctic Science Platform
Year Published: 2022
Document Type: Case Studies
Summary: The long-term perspective of the Antarctic Science Platform has afforded research partners the certainty to invest in new equipment.
