Many Antarctic marine organisms have evolved in stable, cold-ocean conditions and possess limited capacities to respond to environmental fluctuations. Researchers aim to understand the effects of ocean acidification and the projected rise in mean sea-surface temperature on the physiological performance, growth, and development of early life stages (egg, larval, and juvenile) of Antarctic notothenioid fishes, the dominant fish of the Antarctic marine ecosystem. They will examine the specific mechanisms notothenioids use to respond to changes in ocean conditions at the molecular, cellular, and physiological levels during development.
Field Season Overview:
The field team will be making daily to twice daily trips on the sea ice where they will erect fish huts and use a Reed Drill to drill 8 to 10 holes through which they will fish with traps. In addition, ASC divers will collect fish and fish eggs for further study in the Crary Lab. Some samples will be returned to the home institution.
