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.
New Southern Ocean transfer function for subsurface temperature prediction using radiolarian assemblages
Authors: M.Civel-Mazens, G.Cortese, X.Crosta, K.Lawler, V.Lowe, M.Ikehara, T.Itaki
Year Published: 2023
Document Type:
Papers
Ownership: Marine Micropaleontology
Summary: A Southern Ocean-wide transfer function (TF) for subsurface temperature reconstructions (subST) using the Southern Ocean RAdiolarian Dataset (SORAD).
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.
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 #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.
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.
