Studying and Conserving Antarctic Ecosystems

Antarctica is one of the most remote regions on the planet, but it contains rich natural resources of scientific and economic value. Twenty-five nations, including the United States, work together through an international agreement called the Convention for the Conservation of Antarctic Marine Living Resources to study and manage Antarctica's living marine resources using an ecosystem-based approach. Scientists studying the Antarctic look at the whole ecosystem, from tiny krill to penguins and seals, to monitor and predict the effects of human harvest. Fisheries for finfish and krill are managed under a precautionary approach to ensure sustainable harvest levels.
