Supporting Stations: Palmer Station
Research Locations: Palmer Lab
Field team members will conduct prolonged exposure experiments with Antarctic krill (Euphausia superba) to pinpoint the underlying physiological mechanisms of carbon dioxide- and temperature-induced responses, determine potential costs of increased energetic demand at elevated CO2 levels, determine potential acclimation of krill to high CO2 and temperature, and understand the associated feedbacks on the ecosystem and biogeochemical cycles. The goals of the study are: (1) To examine the independent and synergistic effects of CO2 and temperature on acid-base regulation and metabolic physiology of adult Antarctic krill; and (2) Determine potential costs in growth and reproduction of Antarctic krill due to the increased energetic demand of acid-base regulation to compensate for elevated carbon dioxide.
Field Season Overview:
Researchers will conduct CO2 perturbation experiments at Palmer Station using on-site aquarium tanks, a large walk-in incubator, and laboratory space for running real-time carbonate chemistry samples. This year their work will focus on the independent and synergistic effects of CO2 and temperature on metabolism of adult krill. Krill will be collected in the Palmer region by Dr. Deborah Steinberg's group aboard the ARSV Laurence M. Gould at the beginning and end of the annual Long Term Ecological Research (LTER) cruise.
