In 1980, the 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 2” component of the McMurdo LTER. Its primary focus is the physical limnology of the McMurdo Dry Valley lakes. This year’s goals are: (1) to upgrade and maintain long-term automated lake monitoring equipment; (2) carry out manual lake hydrologic balance measurements (lake level and ablation); (3) measure the movement of surface ice using high-precision GPS; (4) characterize signatures and patterns of benthic productivity (using SCUBA); and (5) collect sediment and water samples for a suite of geochemical experiments.
Field Season Overview:
Three participants will be based at the established field camps—Fryxell, Bonney, Hoare—and make day trips by helicopter to Wright and Victoria Valleys. With UNAVCO’s assistance, they will also survey established ablation stakes in the Taylor Valley. Team members will SCUBA diving at Lake Fryxell in order to continue benthic studies in collaboration with the New Zealand Antarctic program.
