Matthew R. Siegfried
Matt, a postdoctoral scholar in the Scripps Glaciology Group, studied arsenic circulation in an Italian hydrothermal groundwater system as an undergraduate at Dartmouth College (2008). He subsequently decided to stay in Hanover as Dr. Bob Hawley's first graduate student, moving his focus from geochemistry to geophysics. In Dr. Hawley's glaciology lab, Matt used repeat high-precision GPS transects near Summit, Greenland to assess the precision and accuracy of the Geosciences Laser Altimeter System (GLAS) onboard the Ice, Cloud, and land Elevation Satellite (ICESat). For his PhD with Dr. Helen Fricker, Matt continued his GPS and remote sensing work as part of the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project on the Siple Coast of the West Antarctic Ice Sheet, taking part in the 2011-2012, 2012-2013, 2013-2014, and 2014-2015 WISSARD field seasons in Antarctica. As a postdoctoral scholar, he joined the Ross Ocean and ice Shelf Environment and Tectonic setting Through Aerogeophysical surveys and modelling (ROSETTA-Ice) project to map the Ross Ice Shelf cavity, deploying to Antarctica with the ROSETTA team for the 2015-2016 field campaign. During his time in Antarctica with ROSETTA, he kept an online diary for Nature News, which can be read here. His final Antarctic field season as part of Scripps Glaciology will be as scientific lead for the 2016-2017 season of the Subglacial Antarctic Lakes Scientific Access (SALSA) Project, a new project to study to quantify the role of subglacial lakes in the carbon cycle. His field experience can be followed on twitter, on our field blog, and on instagram.
