Initially funded in 1980, the U.S. Long-Term Ecological Research (LTER) network is a collaborative effort involving more than 1,800 scientists and students. The McMurdo LTER program is an inter-disciplinary and multi-disciplinary study of the aquatic and terrestrial ecosystems in the ice-free McMurdo Dry Valleys. It is one of 26 LTER sites where researchers are studying ecological processes over long temporal and broad spatial scales. Researchers focusing on lakes will continue their long-term measurements of biological, chemical, and physical limnological properties of Dry Valley lakes and lake ice, with special emphasis on LTER core research areas. This six-year award cycle comprises seven collaborative projects: C-504-M (Gooseff), C-505-M (Priscu), C-506-M (Gooseff), C-507-M (Wall), C-508-M (Barrett), C-509-M (Lyons), and C-511-M (Doran).
Field Season Overview
Participants will make routine lake measurements, periodically occupying field camps at Lakes Bonney, Hoare, and Fryxell from early November to early January in two rounds of site visits. The team will retrieve and re-deploy sediment traps in East and West Lake Bonney and will camp for at least five nights at Lake Miers to measure biological, chemical, and physical limnological properties. They will also collect samples from Lake Chad at the end of the first round of site visits. Team members will work with C-511-M (Doran) on the Autonomous Lake Profiling and Sampling (ALPS) project, retrieving and deploying the automated samplers in Lake Bonney. The project also aims to collect ice cores from the lake ice covers on Lakes Fryxell and Hoare, East and West Lake Bonney, the Canada and Commonwealth Glaciers, and the New Harbor sea ice.
