Climate mitigation through biological conservation: Extensive and valuable blue carbon natural capital in Tristan da Cunha’s giant Marine Protected Zone
Read more of: Climate mitigation through biological conservation: Extensive and valuable blue carbon natural capital in Tristan da Cunha’s giant Marine Protected ZoneCarbon-rich habitats can provide powerful climate mitigation if meaningful protection is put in place. We attempted to quantify this around the Tristan da Cunha archipelago Marine Protected Area. Its shallows […]

Richness, growth, and persistence of life under an Antarctic ice shelf
Read more of: Richness, growth, and persistence of life under an Antarctic ice shelfWhere polar ice sheets meet the coast, they can flow into the sea as floating ice shelves. The seabed underneath is in complete darkness, and may be Earth’s least known […]

Stepping stones towards Antarctica: Switch to southern spawning grounds explains an abrupt range shift in krill
Read more of: Stepping stones towards Antarctica: Switch to southern spawning grounds explains an abrupt range shift in krillPoleward range shifts are a global-scale response to warming, but these vary greatly among taxa and are hard to predict for individual species, localized regions or over shorter (years to […]

Examination of radiation belt dynamics during substorm clusters: Activity drivers and dependencies of trapped flux enhancements
Read more of: Examination of radiation belt dynamics during substorm clusters: Activity drivers and dependencies of trapped flux enhancementsDynamical variations of radiation belt trapped electron fluxes are examined to better understand the variability of enhancements linked to substorm clusters. Analysis is undertaken using the Substorm Onsets and Phases […]

Parker Ice Tongue collapse, Antarctica, triggered by loss of stabilizing land-fast sea ice
Read more of: Parker Ice Tongue collapse, Antarctica, triggered by loss of stabilizing land-fast sea iceAfter a likely multi-century period of intermittent calving, the full length of Parker Ice Tongue (18 km or 41 km2), calved in March 2020 co-incident with repeated summer break-outs of […]

Commercial fishery disturbance of the global ocean biological carbon sink
Read more of: Commercial fishery disturbance of the global ocean biological carbon sinkPlankton drive a major sink of carbon across the global oceans. Dead plankton, their faeces and the faeces of plankton feeders, form a huge rain of carbon sinking to the […]

Vision transformers and techniques for improving solar wind speed forecasts using solar EUV images
Read more of: Vision transformers and techniques for improving solar wind speed forecasts using solar EUV imagesExtreme-ultraviolet images taken by the Atmospheric Imaging Assembly make it possible to use deep vision techniques in the prediction of solar wind speed – a difficult, high-impact, and unsolved problem. […]

Supervised classification of slush and ponded water on Antarctic ice shelves using Landsat 8 imagery
Read more of: Supervised classification of slush and ponded water on Antarctic ice shelves using Landsat 8 imagerySurface meltwater is becoming increasingly widespread on Antarctic ice shelves. It is stored within surface ponds and streams, or within firn pore spaces, which may saturate to form slush. Slush […]

Summer variability of the atmospheric NO2 : NO ratio at Dome C on the East Antarctic Plateau
Read more of: Summer variability of the atmospheric NO2 : NO ratio at Dome C on the East Antarctic PlateauPrevious Antarctic summer campaigns have shown unexpectedly high levels of oxidants in the lower atmosphere of the continental plateau and at coastal regions, with atmospheric hydroxyl radical (OH) concentrations up […]
