Laura Glastra is a Ph.D. student in Physical Oceanography at the University of Rhode Island's Graduate School of Oceanography. Her research focuses on gas exchange processes in polar regions, specifically how noble gases are partitioned between sea ice and seawater during freezing. She is currently carrying out laboratory experiments to provide further insight to this process. On the 2022 TARSAN cruise she will be collecting samples of seawater for isotopic analysis of noble gases, which can be used as physical tracers to help identify water masses such as glacial meltwater.
