Current marine protected areas in the Southern Ocean need to be at least doubled to adequately safeguard the biodiversity of the Antarctic, according to a new CU Boulder study published today, Earth Day, in the journal PLOS ONE.
Proposals under consideration by an international council this year would significantly improve the variety of habitats protected, sustain fish populations and enhance the region’s resilience to the effects of climate change, the authors say.
“Compared to the rest of the world's oceans, we have some of the healthiest marine systems left in the world in Antarctica,” said Cassandra Brooks, author of the new paper and assistant professor in the Environmental Studies Program. “But there are vast areas of the Southern Ocean that are left completely unprotected.”
Many international targets suggest that 10 to 30 percent of the world’s combined oceans should be protected. The Southern Ocean, which surrounds Antarctica, comprises about 10 percent of the world's oceans, and its protection can play a large role in accomplishing this goal.
