In 1980, the National Science Foundation (NSF) funded the US Long Term Ecological Research (LTER) Network, a collaborative effort involving more than 1,800 scientists and students. The McMurdo LTER is one of 26 sites that investigates ecological processes over long temporal and broad spatial scales. 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. This six-year award cycle comprises seven collaborative projects: Andrew Fountain B-504, John Priscu B-505, Diane McKnight B-506, Diana Wall B-507, Jeb Barrett, B-508, Berry Lyons B-509, and Peter Doran B-511. This project is the “Lakes 1” component of the McMurdo LTER. Researchers 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.
Field Season Overview:
Five participants will make routine lake measurements, peridocally occupying field camps at Lakes Bonney, Hoare and Fryxell from early November to early January. Sediment traps will be retrieved and re-deployed in East and West Bonney between mid-November and mid-December. They will camp for at least five nights at Lake Miers to measure biological, chemical, and physical limnological properties. Team members will visit the ice edge or an ice hole in McMurdo Sound to calibrate the Seabird CTD (conductivity/temperature/depth) instrument. Other work sites may include, depending on logistics and weather, Blood Falls, the Canada Glacier, and Don Juan Pond.
