Supporting Stations: McMurdo Station
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. Streams component researchers will continue to operate a network of 16 stream-flow gauges, collect water quality samples from 30 streams, and make hydrologic measurements. 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
The operational support needed for this season will be similar to past seasons with the addition of establishing a new stream gage in Garwood Valley. Our primary activities will be long term stream monitoring and biological surveying conducted in the Dry Valleys. Our work from November to February will involve collaboration with other events in the MCMLTER project, especially the soils and biogeochemistry teams, and with several ASC units providing logistical support from Environmental, BFC, MACOPS, as well as helicopter support. We will spend the majority of the season at the Dry Valley field camps. We will be the primary occupants of the F6 field camp.
Additionally, Christa Torrens will be doing nutrient uptake experiments on six streams within Taylor Valley.
