Mike MacFerrin

Mike MacFerrin is a research associate in the Cooperative Institute for Research in Environmental Sciences (CIRES) and in our group at the University of Colorado in Boulder. Dr. MacFerrin's specialties focus on the interactions of increased meltwater on snow and firn properties on the Greenland ice sheet, with a secondary specialty in using Computer Vision and Machine Learning technologies to extract information from satellite and airborne remote sensing observations. MacFerrin's PhD work resulted in the discovery of a new meltwater runoff mechanism occurring in Greenland that is beginning to rapidly accelerate runoff from the upper-elevation interior of Greenland, further enhancing its contributions to sea-level rise. The work was published in the journal Nature, "Rapid expansion of Greenland's low-permeability ice slabs".

In addition to his research, MacFerrin works as a part-time faculty at the University of Colorado, teaching Remote Sensing and Introduction to Climate Change for the Geography and Atmospherice & Oceanic Sciences departments, respectively. Dr. MacFerrin is also engaged in science outreach and, time allowing, available for speaking events and other engagements about ice sheet science and glaciology. His talks and commentaries have been featured in several podcasts, TV productions, and public talks in recent years.

Rajashree Tri Datta (Faculty at TU Delft)

Tri Datta was a research associate in the Department of Atmospheric and Ocean Sciences at the University of Colorado Boulder.  Dr. Datta's research focuses on how atmospheric drivers affect the surface mass balance of the surface of ice sheets and ice shelves. Dr. Datta is particularly interested in how extreme events can affect surface mass balance non-linearly. The main tool Dr. Datta uses is a variable-resolution version of the global climate model CESM2 (VR-CESM). Dr. Datta has also designed and run a new grid with a higher-resolution domain over Antarctica to examine the effect of large-scale drivers (e.g. circulation and sea ice conditions) on precipitation. Dr. Datta is especially interested in extreme precipitation events which can produce large quantities of snow over Antarctica in very short periods of time.
