Deploying Team Members: Brent C Christner . Christine M Foreman . Jill Mikucki . Nicholas Stevens
Research Objectives: Lake pelagic and benthic productivity and microbial food webs component of McMurdo LTER. The group will continue measurements of biological, chemical, and physical limnological properties of Dry Valley lakes, with special emphasis on LTER core research areas. They will also measure other parameters relevant to modeling the Taylor Valley Lake Ecosystems.

Field Season Overview:
The researchers plan to measure the biological, chemical, and physical properties of Dry Valley lakes, including parameters relevant to modeling the Taylor Valley Lake ecosystems. Team members will use ice augers and other coring devices to penetrate lake ice caps for collecting water samples and retrieving and deploying sediment traps and quantum sensors.

Support contractor personnel will provide helicopter support between McMurdo and the Dry Valleys. They will also facilitate camp put-ins, moves, close out, and transportation of scientific samples back to McMurdo.
