Impacts of local oceanographic processes on Adélie penguin foraging ecology over Palmer Deep

Program Manager:

Event Number: B-005-P

Supporting Stations:  Palmer Station
Research Locations:  Palmer Deep

Project Description:
The application of innovative ocean-observing and animal-telemetry technology over Palmer Deep (Western Antarctic Peninsula; WAP) is leading to new understanding and also to many new questions related to polar ecosystem processes and their control by bio-physical interactions in the polar environment. This multi-platform field study will investigate the impact of coastal physical processes, e.g., tides, currents, upwelling events, and sea ice, on Adélie penguin foraging ecology in the vicinity of Palmer Deep off Anvers Island, WAP. Research efforts will be guided by real-time surface convergences and divergences based on remotely sensed surface-current maps derived from a coastal network of high-frequency radars. The multidisciplinary research team will adaptively sample the distribution of phytoplankton and zooplankton, which influence Adélie penguin foraging ecology, to understand how local oceanographic processes structure the ecosystem.

Field Season Overview:
Field team members will sail to Palmer Station on the ARSV Laurence M. Gould. During the transit to station they will deploy a mooring that will remain in place and collect data for 12 months. Once on station, they will deploy a single High Frequency Radar (HFR) site, scout for specific HFR sites for next year on Joubin and Wauwermans Islands, conduct Zodiac-based acoustic surveys and net sampling over fixed grid to determine Antarctic krill distribution patterns and densities.

Deploying Team Members:

  • Kim Bernard (Co-PI)
  • Josh Kohut (PI)
