Chinstrap penguins rest on an iceberg off the coast of Elephant Island, Antarctica.

Greenpeace has partnered with penguin researchers from Stony Brook University and Northeastern University to study the impact of climate change on fragile chinstrap penguin colonies in Antarctica. The voyage to Antarctica is the last stop of the Protect the Oceans Expedition aimed at highlighting the threats facing our oceans and the urgent need for their protection under a new Global Ocean Treaty.
