After 10 days of weather delays at the end of March and beginning of April, a team from the University of Utah and NASA were able to investigate the physical properties of a firn aquifer in southeast Greenland. Following up on their first expedition to the region in 2013, U geography doctoral student, Clément Miège, and research associate for University Space Research Association at NASA Goddard Space Flight, Ludovic Brucker, under the direction of U geography professor Rick Forster, the team was able to install an intelligent weather station and collected more than 17 miles of high-frequency radar data.
The Greenland firn aquifer was discovered accidentally in the spring of 2011 while a team of glaciologists led by Forster were sampling regions of high snow accumulation. A firn aquifer is a reservoir of perennial water (doesn’t freeze in the winter) that is trapped within the compacted snow layer.
