Description

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

Five participants will make routine lake measurements, periodically 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 Lake 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.
