Project Title

Adélie penguin response to climate change in the Ross Sea region – a full life-cycle approach

Outreach for this group has involved several aspects, including calls to school groups from the penguin colony. Pictured here, Jean Pennycook.

Sea-ice on the Ross Sea is expanding. How that affects Antarctic marine biota is unknown. This study aims to better understand the biotic effects of these changes using a widely recognized indicator species, the Adélie penguin. Researchers will outfit penguins with time-depth recorders to monitor foraging efforts and record breeding activities of marked individuals. These data will lead to a better understanding of how changing sea-ice conditions affect penguins through their annual cycles and through individuals’ lifetimes, and will infer how climate change may influence their populations.

Field Season Overview

Participants will deploy this season to continue their long-term study of Adelie Penguin demographics and response to environmental change in the Ross Sea. Deployments will be staggered throughout the field season. Team members will travel by helicopter and occupy camps at two field sites, Cape Royds and Cape Crozier, starting in late October. They will identify marked penguins at each location, collect breeding behavior data, deploy various instrumentation to obtain foraging and location data, and band new penguins near the end of the season.
