Project Description:
Initially funded in 1980, the US 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 that investigates ecological processes over long temporal and broad spatial scales. Project researchers will continue measurements of physical properties of Dry Valley glaciers and meteorology, with special emphasis on LTER core research areas. 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.

Field Season Overview:
Our support requirements are similar to previous seasons. We will occupy the Lake Hoare camp from Nov 4 to Jan 30. We will make day trips to the Commonwealth, Howard, Canada, and Taylor glaciers to conduct mass balance measurements and biological studies. Day trips will also be made to various meteorological stations in Taylor, Wright, Victoria, Garwood and Miers valleys. Several sensors and dataloggers on the meteorological stations will be swapped out and sent back to the manufacture for recalibration as in previous seasons. The replacement meteorological sensors and dataloggers will remain in the field for 2 to 5 years. Day trips will also be made to Budda Lake in Garwood Valley to monitor the hydrologic conditions. Day trips will be made to upper Taylor, Wright, and Victoria Valleys to acquire glacier repeat photographs at established locations.
