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.
Warm Water Is Rapidly Eroding Antarctica’s Ross Ice Shelf
The underside of the world’s largest ice shelf is melting—by meters per year in some places—because of the seasonal inflow of water heated by the Sun, observations of the White Continent reveal.
Plastic Fragments Found for the First Time on a Glacier
The discovery, made in the Italian Alps, confirms the ubiquity of plastic pollution worldwide.
Fast-Melting Mountain Glaciers Speed Up Sea Level Rise
Satellites spy on remote alpine glaciers, producing more accurate—and higher—estimates of ice loss over time.
How Do Intergranular Particles Affect the Flow of Ice?
Laboratory experiments that indicate rock particles can impede sliding along grain boundaries in ice may help researchers more accurately determine the composition of planetary ice masses.
Decadal Changes in Glacial Discharge in the High Alps
A new statistical analysis of daily, glacial runoff cycles offers a unique way of examining how Alpine glaciers have responded since the onset of rapid regional warming in the 1980s.
Very Warm Water Observed Along West Antarctic Ice Shelf
Two years of mooring observations at the edge of the continental shelf show that wind stress and upwelling control the inflow of some of the warmest water observed at an ice shelf front in Antarctica.
