About Gabriela

Gabi Collao-Barrios is a postdoc at NSIDC. Her research focuses on two different aspects of the cryosphere. One is investigating the main processes involved in the snowpack spatial and temporal evolution in the Rocky Mountains, using field data (NASA SnowEX data) and modeling (SnowModel). The other is analyzing ice flow changes in the western Antarctic ice shelves, using satellite data (GO_LIVE project and collaboration with TARSAN Thwaites Glacier Project).

Specialties

Ice dynamics and mass balance, snow processes, surface mass balance and climate modeling

Current Research

Snowpack evolution in the Rocky Mountains: Spatial and temporal evolution of snow accumulation and melt exert dominant control on hydrological resources and biogeochemical flows in temperate mountain catchments. Collao-Barrios investigates the main processes involved in evolution in the snowpack of the East River basin in the Rocky Mountains, combining modeling, field measurements, and spatially distributed data from NASA's SnowEX campaigns. She is particularly interested in the effect of wind redistribution, dust in albedo, and land cover.

Ice dynamics changes in the Amundsen Sea Embayment ice shelves in Antarctica: Ice shelves are key components of glacier outlet systems, providing a resisting stress on glacier flow and keeping an important control on ice sheet discharge and mass loss, thereby affecting sea level rise rates. Collao-Barrios studies dynamic changes on ice shelves located on the western side of the Amundsen Sea Embayment, the region with the largest ongoing ice mass loss. Her research focuses on the changes in flow direction and the relation with tides, using satellite data (GO_LIVE and ITS_LIVE data), with the objective of identifying links with the weakening and destabilization of ice shelves.
