First-ever layered lake-sediment sample extracted from subglacial Antarctica

Payne Institute Faculty Fellow Matthew Siegfried is part of a NSF-funded project Subglacial Antarctic Lakes Scientific Access (SALSA), that have extracted a layered lake-sediment sample that gives important details into past dynamics of the Antarctic ice sheet and its cold, dark ecosystems. Their findings from analysis of the sediment sample, give important insight into the larger dynamics of the Antarctic ice sheet and its history, including when the ice sheet was smaller than its current size.
