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).
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.
Scientists chart 45 million years of Antarctic temperature change
Authors: Te Herenga Waka—Victoria University of Wellington, GNS Science, and Birmingham University (UK)
Year Published: 2022
Document Type:
Papers
Summary: New study shows 'very clear and direct response' of Antarctic temperatures to changing carbon dioxide levels. Molecular fossils and computer modelling have enabled scientists to build the first catalogue of Antarctic ocean temperatures over the past 45 million years, offering new insights into future sea level changes.
On the Precipice
Authors: GNS Science—Te Pū Ao, Te Herenga Waka—Victoria University of Wellington and Antarctic Science Platform
Year Published: 2021
Document Type:
Reports, Papers
Ownership: GNS Science—Te Pū Ao
Summary: The numbers are sharp and the repercussions alarming — but it’s not too late. We still have a chance to curb CO2 emissions before we reach a climate tipping point.
Choosing the future of Antarctica
Authors: S. R. Rintoul, S.L. Chown, R.M. DeCento, et all
Year Published: 2021
Document Type:
Papers
Summary: We present two narratives on the future of Antarctica and the Southern Ocean, from the perspective of an observer looking back from 2070. In the first scenario, greenhouse gas emissions remained unchecked, the climate continued to warm, and the policy response was ineffective; this had large ramifications in Antarctica and the Southern Ocean, with worldwide impacts. In the second scenario, ambitious action was taken to limit greenhouse gas emissions and to establish policies that reduced anthropogenic pressure on the environment, slowing the rate of change in Antarctica.
Ocean mixing and heat transport processes observed under the Ross Ice Shelf control its basal melting
Authors: Stevens, C., Hulbe, C., Brewer, M., et al.
Year Published: 2020
Document Type:
Papers
Ownership: ASP
Summary: This published PNAS research article describes measurements of the ocean beneath the centre of the Ross Ice Shelf, to better understanding the complex processes that drive melting.
