Satellites detect undiscovered penguin populations

Penguin populations are a key environmental indicator of overall ecosystem health that help guide Antarctic conservation policy. When researchers using Landsat imagery detected a previously unknown colony of Adélie penguins off the coast of Antarctica, the robustness of the colony helped inform new species abundance and distribution models in the region, and led to the revision of the boundaries of a regional protected area.
