Mesosphere and lower thermosphere winds and tidal variations during the 2019 Antarctic Sudden Stratospheric Warming
Read more of: Mesosphere and lower thermosphere winds and tidal variations during the 2019 Antarctic Sudden Stratospheric WarmingRealistic modeling of the winds and dynamical variations in the mesosphere and lower thermosphere (MLT) at Southern Hemisphere (SH) mid-to-high latitudes near 60oS where dramatic motions occur has been a […]

Using metabarcoding to assess Viridiplantae sequence diversity present in Antarctic glacial ice
Read more of: Using metabarcoding to assess Viridiplantae sequence diversity present in Antarctic glacial iceAntarctica contains most of the glacial ice on the planet, a habitat that is largely unexplored by biologists. Recent warming in parts of Antarctica, particularly the Antarctic Peninsula region, is […]

Modelling the exposure of satellites in medium Earth orbit to proton belt radiation
Read more of: Modelling the exposure of satellites in medium Earth orbit to proton belt radiationGeomagnetically trapped protons forming Earth’s proton radiation belt pose a hazard to orbiting spacecraft. In particular, solar cells are prone to degradation caused by non-ionising collisions with protons in the […]

The vertical structure and entrainment of subglacial melt water plumes
Read more of: The vertical structure and entrainment of subglacial melt water plumesBasal melting of marine-terminating glaciers, through its impact on the forces that control the flow of the glaciers, is one of the major factors determining sea level rise in a […]

Sea ice concentration impacts dissolved organic gases in the Canadian Arctic
Read more of: Sea ice concentration impacts dissolved organic gases in the Canadian ArcticThe marginal sea ice zone has been identified as a source of different climate-active gases to the atmosphere due to its unique biogeochemistry. However, it remains highly undersampled, and the […]

Sensitivity of the West Antarctic Ice Sheet to +2 °C (SWAIS 2C)
Read more of: Sensitivity of the West Antarctic Ice Sheet to +2 °C (SWAIS 2C)The West Antarctic Ice Sheet (WAIS) presently holds enough ice to raise global sea level by 4.3 m if completely melted. The unknown response of the WAIS to future warming remains […]

Ducted chorus waves cause sub‐relativistic and relativistic electron microbursts
Read more of: Ducted chorus waves cause sub‐relativistic and relativistic electron microburstsDuring magnetospheric storms, radiation belt electrons are produced and then removed by collisions with the lower atmosphere on varying timescales. An efficient loss process is microbursts, strong, transient precipitation of […]

Simulated twentieth-century ocean warming in the Amundsen Sea, West Antarctica
Read more of: Simulated twentieth-century ocean warming in the Amundsen Sea, West AntarcticaRapid ice loss is occurring in the Amundsen Sea sector of the West Antarctic Ice Sheet. This ice loss is assumed to be a long-term response to oceanographic forcing, but […]

Physiological and metabolic characteristics of polar diatoms: insights into cold adaptation and potential biotechnology
Read more of: Physiological and metabolic characteristics of polar diatoms: insights into cold adaptation and potential biotechnologyThe polar regions represent two of the most extreme environments on Earth, with sub-zero temperatures, sustained light in the summer and complete darkness in the winter. Marine diatoms are prevalent […]

Double diffusion as a driver of turbulence in the stratified boundary layer beneath George VI Ice Shelf
Read more of: Double diffusion as a driver of turbulence in the stratified boundary layer beneath George VI Ice ShelfWarmer and more persistent intrusions of Circumpolar Deep Water (CDW) onto the West Antarctic Peninsula are a key driver of the recent increase in ice shelf mass loss. The relatively […]
