Supporting Stations: McMurdo Station
Research Locations: Lakes Bonney, Fryxell, Hoare
Researchers will deploy autonomous instrumentation in selected Taylor Valley lakes to collect the first below-ice suite of physical, chemical, and biological data during the polar night. Their proposed research will test the overarching hypothesis that the winter darkness induces a cascade of physiological changes that alters the biodiversity and functional roles of autotrophic and heterotrophic microplankton within the lakes.
Field Season Overview:
LTER camp staff will deploy Autonomous Lake Profiling and Sampling (ALPS) stations in both the east and west lobes of Lake Bonney. These stations will add to existing Long-Term Ecological Research (LTER) monitoring equipment and will consist of ice-tethered profilers, phytoplankton samplers, and remote-access samplers, along with requisite power and communication. The stations will operate year-round.
