An instrument-laden submersible reveals where—and how rapidly—the Antarctic glacier is melting.

An Innovative Approach to Model Complex Hurricane Flood Hazards
A new study shows that it is possible to produce regional assessments of how hurricane flood hazards change due to both evolving storm tides and precipitation rates in a warming climate.
Surface Temperature Sets the Pace of Sea Level Rise
Reining in global mean sea level rise from land-ice wastage and ocean thermal expansion requires reducing global mean surface temperatures to near-preindustrial values.
A Close Look at Melting Below Antarctica’s Largest Ice Shelf
Radar data reveal where, when, and how fast the base of the Filchner-Ronne Ice Shelf has been losing mass in recent years.
Seafloor Reveals a Period of Rapid Retreat for Thwaites Glacier
New high-resolution seafloor imagery shows a series of delicate ridges produced by the glacier’s front as it bobbed daily with the tides, revealing a recent period of rapid retreat.New high-resolution seafloor imagery shows a series of delicate ridges produced by the glacier’s front as it bobbed daily with the tides, revealing a recent period of rapid retreat.
When Projecting Coastal Resilience, Sediment Compaction Is Key
The addition of new sediment helps build up lowland environments like deltas and marshes, but it also compacts materials beneath it—a vital, but often overlooked, factor in landscape evolution studies.
Tracking Subsidence on Deltas With Fiber-Optics
Fiberoptic strain meters capable of measuring micron-scale subsidence reveal a Holocene sediment package on the Mississippi Delta that is mostly stable.
Models Oversimplify How Melting Glaciers Deform Land
When glaciers melt, the land below deforms. Sea level data show that widely used models oversimplify the process.
Modeling the Ice Flow and Evolution of Glaciers
Glaciers are crucial water resources and important sea level contributors. To accurately model glacier evolution, their mass balance and ice flow processes must be accounted for.
Seashells and Penguin Bones Reveal Thwaites Glacier’s Quiet Past
Antarctica’s Thwaites and Pine Island Glaciers are melting faster than they have in the past 5,500 years, new evidence shows. Against expectations, their pasts have been remarkably stable.
