Seabirds are Indicator Species for Climate Change

It has been said that seabirds are key indicators of the impact of climate change on the world’s oceans. How exactly? In Antarctica, for example, seabirds depend on ice: Seabirds eat fish, which eat krill. The krill eat algae, and the algae grow underneath sea ice. With warming oceans, and less ice, there will major consequences for this food chain. In an effort to quantify and model how seabirds will fare in the face of climate change, Stephanie Jenouvrier, a biologist at Woods Hole Oceanographic Institution (WHOI), investigates the topic.
