Greenland Ice Sheet Beats All-Time 1-Day Melt Record
More ice melted from the ice sheet on 1 August 2019 than any other day on record.
Tracking Earth’s Shape Reveals Greater Polar Ice Loss
Researchers offer a solution to better track mass changes in ocean water and polar ice.
Spy Satellite Reveals Accelerated Pace of Himalayan Glacier Melt
Images taken covertly in the 1970s have taken on a new purpose in a recent glaciology study.
Arctic Glacial Retreat Alters Downstream Fjord Currents
High-resolution mapping efforts could improve predictions of coastal changes as glaciers shrink around the world.
Modeling the Subsurface Hydrology of the Greenland Ice Sheet
Firn aquifers—pockets of meltwater beneath the surface of an ice sheet—could have far-reaching impacts on subglacial hydrology, a new study finds.
Creating Icebergs in Ocean Models Coupled to Ice Shelves
Modeling icebergs as Lagrangian elements held together by numerical bonds provides insights into coupled exchanges of heat, freshwater, and momentum between large icebergs and the ocean.
Missing Lakes Under Antarctic Ice Sheets
New radio sounding study finds little evidence of lakes under Antarctica’s Recovery Glacier.
Mapping Subglacial Meltwater Channels
Researchers find that past studies underestimate the friction meltwater channels exert on glaciers by orders of magnitude.
Seismic Clues to Surging Glaciers
Measuring seismic waves passing through a glacier suggests that not only is liquid water playing a role in periodic surging but the water is channeled into cracks from across the ice.
