"Kirsty Tinto and other Lamont colleagues are mapping the rocks and sediments beneath the Amundsen Sea Embayment, one of the fastest-changing parts of Antarctica, to understand how the hidden landscape affects ice flow and stability. They've combined airborne, marine and land-based data to develop a new set of "bedclasses" that group areas with similar geological traits, such as hardness or heat flow."
"Andrew Robertson (Center for Climate Systems Research) and colleagues are testing new ways to predict rainfall up to a month ahead of time, using NASA's GEOS subseasonal-to-seasonal (S2S) model and a statistical approach that uses observed relationships in the atmosphere to emulate how rainfall patterns develop. More reliable forecasts on a 2-4 week timescale could lead to more accurate early warning systems that help communities prepare for flood, droughts or crop stress."
Researchers at Lamont-Doherty are mapping rocks and sediments beneath the Amundsen Sea Embayment to determine how the hidden landscape influences ice flow and stability. Airborne, marine, and land-based data were combined to create "bedclasses" that group areas by geological traits like hardness and heat flow, with the goal of making ice-sheet models more realistic and improving estimates of Antarctica's contribution to sea-level rise. Separate work tests rainfall prediction up to a month ahead using NASA's GEOS S2S model paired with a statistical emulator of atmospheric relationships. Improved two-to-four-week forecasts aim to strengthen early-warning systems for floods, droughts, and crop stress.
