The Subglacial Antarctic Lakes Scientific Access (SALSA) project aims to uncover new knowledge about this newly explored biome through an integrative study of subglacial geobiology, water column and sedimentary organic carbon, and geobiological processes in one of the largest subglacial lakes in West Antarctica.

The Subglacial Antarctic Lakes Scientific Access (SALSA) project is an integrative study of subglacial geobiology, water column and sedimentary organic carbon, and geological processes in Lake Mercer, one of the largest subglacial lakes in West Antarctica.
