The Subglacial Antarctic Lakes Scientific Access (SALSA) project will use a clean access hot water drill to penetrate into Subglacial Lake Mercer (SLM), one of the largest and most dynamic subglacial lakes on the Whillans Ice Plain. The lake is hydraulically active with water replacement times on the order of a decade. The team will collect samples of basal ice, sediments, and lake water to explain how relict organic matter deposited during marine incursions influences contemporary biodiversity and carbon cycling and to provide new information on past climatic conditions.
Field Season Overview
Five team members will deploy during the 2017-18 field season. The sediment laboratory will be cleaned to 14C-dating clean specifications, and a sea ice test of the Deep SCINI ROV will be conducted. Time will also be dedicated to education and outreach including filming of the drill preparation and the Deep SCINI ROV sea ice test. One of the deploying grantees shall participate for up to 3 weeks filming the traverse from Camp20 to SLM as the traverse field team stages containers at SLM for use during the 2018-19 season.
