Ocean layering controls basal melting beneath Ross Ice Shelf
—
in OceanographyWhat the study found The study found a consistently stratified water column beneath the Kamb Ice Stream grounding zone of the Ross Ice Shelf. Warmer inflowing seawater was separated from a colder outflowing mixture of seawater and glacial meltwater, and this layering persisted over the observation period. Why the authors say this matters The authors…
Baranof Island glaciers persisted into the Holocene and then retreated rapidly
Cosmogenic dating and sediment cores reveal glacial history of Baranof Island and document tenfold acceleration in glacier retreat since 1986, with implications for sea-level rise.
Sea ice reference data prepared for satellite altimetry comparison
A standardized collection of sea ice measurements from 1993–2024 enables validation of satellite altimetry thickness products across both polar regions at matching spatial and temporal scales.
Global glacial lakes store more water but vary widely in longevity
Study quantifies 71,000 glacial lakes globally, estimating 2,048 km³ of freshwater storage in 2020 and tracking changes since 1990 across high-mountain regions.
Bias-corrected Greenland accumulation maps align more closely with observations
A statistical method corrects biases in Greenland ice sheet snow accumulation estimates from climate models, reducing uncertainties in sea-level rise projections.
Warming scenario increases rain-on-snow events in Gallatin watershed
SnowModel simulations project increased rain-on-snow events in the upper Gallatin River watershed, with significant hydrologic implications for streamflow and aquatic ecosystems under future.
