Subglacial landscape formation and sediment discharge: relating basal conditions to bedform dimensions and properties at Rutford Ice Stream, West Antarctica
Read more of: Subglacial landscape formation and sediment discharge: relating basal conditions to bedform dimensions and properties at Rutford Ice Stream, West AntarcticaBasal conditions that facilitate fast ice flow are still poorly understood and their parameterization in ice‐flow models results in high uncertainties in ice‐flow and consequent sea‐level rise projections. Direct observations […]

Arctic sea ice hits record winter low for a second year
Read more of: Arctic sea ice hits record winter low for a second year1.3 million km² of ice is missing from the frozen surface of the Arctic Ocean in winter 2026. It’s also much thinner, following a worrying long-term downward trend.

The effect of landfast sea ice buttressing on ice dynamic speedup in the Larsen B embayment, Antarctica
Read more of: The effect of landfast sea ice buttressing on ice dynamic speedup in the Larsen B embayment, AntarcticaWe observe the evacuation of 11-year-old landfast sea ice in the Larsen B embayment on the East Antarctic Peninsula in January 2022, which was in part triggered by warm atmospheric […]

Processed airborne radio-echo sounding data from the FISS 2016 surveys covering the Filchner and Halley Ice Shelves, and the English Coast (western Palmer Land), West Antarctica (2016/2017) – V2
Read more of: Processed airborne radio-echo sounding data from the FISS 2016 surveys covering the Filchner and Halley Ice Shelves, and the English Coast (western Palmer Land), West Antarctica (2016/2017) – V2Three separate airborne radar surveys were flown during the austral summer of 2016/17 over the Filchner Ice Shelf and Halley Ice Shelf (West Antarctica), and over the outlet glacier flows […]

Decadal variability of ice-shelf melting in the Amundsen Sea driven by sea-ice freshwater fluxes
Read more of: Decadal variability of ice-shelf melting in the Amundsen Sea driven by sea-ice freshwater fluxesThe ice streams flowing into the Amundsen Sea, West Antarctica, are losing mass due to changes in oceanic basal melting of their floating ice shelves. Rapid ice-shelf melting is sustained […]

Subglacial bedform and moat initiation beneath Rutford Ice Stream, West Antarctica
Read more of: Subglacial bedform and moat initiation beneath Rutford Ice Stream, West AntarcticaThe accuracy of sea-level rise predictions is highly dependent on reliably understanding the subglacial environment beneath ice streams. Bedforms result from the interaction between ice and its substrate, and therefore […]

Locating subglacial sediments across West Antarctica with isostatic gravity anomalies
Read more of: Locating subglacial sediments across West Antarctica with isostatic gravity anomaliesSubglacial sediments are an important control on fast flowing ice in West Antarctica but their spatial distribution over catchment-wide areas is still largely unknown. Previously, airborne gravity anomalies could not […]

Coupled ice–ocean interactions during future retreat of West Antarctic ice streams in the Amundsen Sea sector
Read more of: Coupled ice–ocean interactions during future retreat of West Antarctic ice streams in the Amundsen Sea sectorThe Amundsen Sea sector has some of the fastest-thinning ice shelves in Antarctica, caused by high, ocean-driven basal melt rates, which can lead to increased ice streamflow, causing increased sea […]
