The McMurdo Long Term Ecological Research (LTER) projects will continue to investigate the McMurdo Dry Valleys as an end-member ecosystem and focus on the relative roles of legacy and extant processes on current biodiversity and ecosystem structure and function. This project measures Dry Valley meteorological parameters and the physical properties of Dry Valley glaciers, with special emphasis on LTER core research areas. The field team will travel via helicopter to the established field camp at Lake Hoare, which team members will use as their base of operations for the season. The researchers will make day trips via helicopter to the Commonwealth, Howard, Canada, and Taylor glaciers to make mass balance measurements. Ice, water, and sediment samples will be collected on the Commonwealth, Canada, and Taylor glaciers. Team members will also make day trips to various meteorological stations in the Taylor, Beacon, Wright, and Victoria Valleys, where they will replace sensors and dataloggers. A new AWS meteorological station will be installed in McKelvey Valley. LiDar measurements will continue at Canada Glacier, Don Juan Pond, and Rock Glacier to capture winter ablation and movement.
