Initially funded in 1980, the U.S. Long-Term Ecological Research (LTER) network is a collaborative effort of more than 1,800 scientists and students. The McMurdo LTER program is a multi-disciplinary aquatic and terrestrial ecosystems study in the McMurdo Dry Valleys. It is one of 26 LTER sites where researchers study ecological processes over long temporal and broad spatial scales. Geochemistry researchers monitor the inorganic geochemistry of water and solid samples collected from Dry Valleys' glaciers, streams, ponds, lakes, and landscape. They also study upland seeps and ponds to gain a better understanding of their hydrologic and geochemical controls. This six-year award cycle comprises seven collaborative projects: C-504-M (Gooseff), C-505-M (Priscu), C-506-M (Gooseff), C-507-M (Adams), C-508-M (Takacs-Vesbach), C-509-M (Gooseff), and C-511-M (Doran).
Algal Ops
Researchers will work out of the F6 and Lake Hoare camps in the Dry Valleys and will access sites by helicopter and on foot. They will survey and sample established algal transects in the Taylor, Wright, Garwood, and Miers Valleys and will use laboratory space at field camps to filter and process samples for transport to Crary Laboratory. Field activities may include: (1) surveying and sampling all 16 established algal transects; (2) continuing work on the Stream Mat Transplant Experiment (SMTE); (3) conducting terrestrial LiDAR surveys of the algal transects with assistance from UNAVCO; and (4) deploying sediment traps on lake surfaces to capture Aeolian deposits with C-505-M (Priscu).
