A new study from lead author Susheel Adusumilli has identified atmospheric rivers, the phenomenon of high-altitude concentrations of water in the atmosphere, as a main source of snowfall on the West Antarctic ice sheet. The project makes use of data from the ICESat-2 satellite which provides measurements of snowpack by observing precise changes in elevation along the surface of the ice sheet.

Comparing climate models with sea ice observations exposes an interesting dilemma: despite model predictions that Antarctic sea ice should be shrinking, it has steadily expanded from 1979 to 2015. Scripps oceanographer Ian Eisenman has collaborated with California Institute of Technology researcher Shantong Sun to address this problem, identifying disparities between sea ice drift between models and real life.

On the latest episode of the San Diego Union Tribune’s Name Drop podcast, Helen Fricker discusses her experiences in Antarctica, the importance of ice sheets to the globe, and what it’s like to study the polar regions using advanced satellite observational instruments.

Continental ice sheets in the Antarctic often produce large, tabular icebergs that release significant volumes of meltwater into the Southern Ocean as they drift away from shore. A new paper authored by Mark England (Scripps, UNCW) addresses how this meltwater flux can be used for better climate predictions in the future.

The British Antarctic Territory has named an ice feature in honor of Scripps glaciologist Helen Fricker’s contributions to Antarctic ice sheet laser-altimetry research. The newly-established Fricker Ice Piedmont is one of many locations named after 28 different Antarctic explorers and researchers.

Scripps Institution of Oceanography is one of five research institutions to assist in the creation of the new Global Ocean Biogeochemistry Array, an NSF-funded expansion of biogeochemical ocean monitoring with autonomous floats. “It’s an evolution of how we’re observing the ocean,” says Lynne Talley, Scripps professor and co-principal investigator on the project. Scripps scientists will be building new floats and coordinating their deployments, producing readily-available data for researchers across the globe.

Using 25 years of satellite data, a new paper by lead author Susheel Adusumilli provides “convincing evidence” that changes in the Southern Ocean are driving Antarctic ice loss. The authors also constructed the longest and most comprehensive record of ice sheet melting in Antarctica, describing the unique changing environment across both Antarctic ice sheets.
