Ice sheets research, explained
11 open-access ice sheets studies, each with a flashcard deck and a quiz.
- Greenland’s hidden fjord floors in BedMachine v3
A 150 m Greenland bed and fjord map raises sea-level potential by 7 cm and shows 30–100% more glaciers can meet warm Atlantic Water.
- SH circulation patterns shape Antarctic snowfall
BAM, SAM, and PSA polarities rearrange Antarctic precipitation, with PSA1 explaining ~40% of daily variability in West Antarctica.
- How Bølling warming and ice saddles fed MWP1a
North American ice-sheet ensembles show saddle collapse and Bølling warming can supply several meters of Meltwater Pulse 1a in 340 years.
- Atmospheric rivers supply ~13% of Antarctic snow
Rare atmospheric rivers deliver about 13% of Antarctic precipitation and explain more than a third of its year-to-year swings.
- A buried Antarctic lake drained through hydrofracture
Ground-penetrating radar caught a buried meltwater lake draining through vertical fractures at an East Antarctic ice-shelf grounding zone.
- Small icebergs add a lot of Greenland fjord freshwater
High-resolution UNet mapping finds far more small icebergs than Sentinel-2 thresholding, raising Sermilik meltwater estimates toward ~2000 m³ s−1.
- Neural nets map CMIP6 weather into Greenland melt
ANNs trained on CESM2 translate CMIP6 atmospheres into Greenland surface-melt increases of about 79–264% by 2100 depending on SSP.
- Why two giant icebergs fertilize the ocean differently
A recently calved iceberg dumped meltwater and triggered a bloom, while a decades-grounded berg barely changed nearby waters.
- Less Arctic sea ice both snows and melts Greenland
Losing Arctic sea ice in a +2 °C world adds winter snow to Greenland but more than offsets it with extra summer melt.
- Soft-bed glaciers show a hydrology continuum
Seasonal ice-speed patterns on Icelandic and Norwegian glaciers reveal mixed, not purely channelized or distributed, soft-bed drainage.
- Proglacial lakes speed Greenland outlet glaciers
Lake-terminating Greenland outlet glaciers flow much faster near their fronts than otherwise similar land-terminating glaciers.
