San Francisco State University
Romberg Tiburon Center
Supporting Stations: McMurdo Station
Research Locations: Taylor Valley
Researchers will study the microbial ecology of soils under and alongside stream beds (the hyporheic zone) and associated arid soils in various McMurdo Dry Valleys systems. They plan to study the biogeochemistry of these sites and the activity, composition, and distribution of the nitrogen-fixing communities. Ultimately, researchers would like to map the distribution of these communities throughout the valley ecosystem, via a landscape model, and extrapolate their influence on total nitrogen budgets.
Field Season Overview:
Five team members will camp for three weeks in the Taylor Valley in a shared camp with the New Zealand Terrestrial Antarctic Biocomplexity Survey (nzTABS) program. They will sample wet regions in the valley by foot and by helicopter. They will also set up a small overnight camp in the Victoria Valley, which will be accessed by helicopter.
