There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Summary Sentence: The Spring 2022 OSE Seminar Series -- Dr. Alex Robel Professor, School of Earth & Atmospheric Sciences, Georgia Tech
Full Summary: The seminar is offered both virtually and in person on the 3rd floor of ES&T in the new Ocean Room.
SP2022 ImageGlaciers in the Arctic and Antarctic have been losing ice at an increasing rate over the last several decades, leading to an acceleration in global sea level rise. Much of this increase has occurred in concert with warming of the ocean water in contact with glaciers at ice sheet margins. However, our understanding and ability to predict these changes is limited by the complex range of processes occurring at glacier-ocean interfaces. In this talk, I will discuss our recent and ongoing efforts to understand and model three of these problems: intrusion of seawater beneath glaciers, turbulent heat entrainment in the ice-water boundary layer, and the mechanical interaction of icebergs with the glacier front. I will conclude by explaining the implications of these small-scale problems for the highly consequential problem of predicting future sea level rise.
