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, sea-ice) on Adélie penguin foraging ecology in the vicinity of Palmer Deep, off Anvers Island, WAP. Guided by real-time surface convergence and divergences based on remotely sensed surface current maps derived from a coastal network of High Frequency Radars (HFRs), a 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)
