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 […]

Deep water inflow slowed offshore expansion of the West Antarctic Ice Sheet at the Eocene-Oligocene transition
Read more of: Deep water inflow slowed offshore expansion of the West Antarctic Ice Sheet at the Eocene-Oligocene transitionThe stability of the West Antarctic Ice Sheet is threatened by the incursion of warm Circumpolar Deepwater which flows southwards via cross-shelf troughs towards the coast there melting ice shelves.

Persistent Ross Sea freshening from imbalance West Antarctic Ice Shelf melting
Read more of: Persistent Ross Sea freshening from imbalance West Antarctic Ice Shelf meltingA 63-year observational record in the southwest Ross Sea shows a continuing, near-linear salinity decrease of 0.170 and slight warming of 0.013°C through 2020. That freshening exceeded any increase in […]

Seasonal and interannual variability of feeding in Antarctic benthos
Read more of: Seasonal and interannual variability of feeding in Antarctic benthosThe seasonal and interannual variability of feeding in 15 species of benthic marine suspension feeder was studied over 8 yr at Ryder Bay, Antarctica. Feeding was strongly seasonal in bryozoans, gorgonians, […]

Under-ice light field analysis in the western Arctic Ocean during late summer
Read more of: Under-ice light field analysis in the western Arctic Ocean during late summerThe Arctic is no longer a region dominated by thick multi-year ice (MYI), but by thinner, more dynamic, first-year-ice (FYI). This shift towards a seasonal ice cover has consequences for […]

Rapid basal melting of the Greenland Ice Sheet from surface meltwater drainage
Read more of: Rapid basal melting of the Greenland Ice Sheet from surface meltwater drainageSubglacial hydrologic systems regulate ice sheet flow, causing acceleration or deceleration, depending on hydraulic efficiency and the rate at which surface meltwater is delivered to the bed. Because these systems […]
