Initially funded in 1980, the U.S. Long-Term Ecological Research (LTER) network is a collaborative effort of more than 1,800 scientists and students. The McMurdo LTER program is a multi-disciplinary aquatic and terrestrial ecosystems study in the McMurdo Dry Valleys. It is one of 26 LTER sites where researchers study ecological processes over long temporal and broad spatial scales. Glacier researchers will continue measurements of physical properties of Dry Valley glaciers and their response to meteorological conditions, 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 (Adams), C-508-M (Takacs-Vesbach), C-509-M (Gooseff), and C-511-M (Doran).
Researchers will divide time between Lake Hoare and F6 camps, with short returns to McMurdo Station to process samples. From camp, they will make day trips to glaciers in the Taylor and Miers valleys. Over the season, they hope to: (1) maintain established active-layer monitoring stations (ALMS); (2) perform mass-balance measurements; (3) collect shallow ice cores and meltwater from glaciers; (4) collect landscape albedo measurements from a helicopter-slinged albedo box over the Taylor Valley; (5) measure dissolved oxygen in supraglacial and valley streams: deploy temperature sensors and a data logger into borehole #11; (6) conduct nutrient uptake experiments in two streams on top Canada Glacier; (7) maintain glacier ice temperature logging stations; (8) collect water samples from glacier cliff faces; and (9) collect stream water and sediment samples.
