Biodiversity in the Baltic Sea

In the spring of 2011, a research crew from Oceana spent two months in the brackish Baltic Sea. The Baltic faces challenges from pollution, algae blooms, over fishing, and invasive species. Oceana researchers gathered data, samples, photographs, and videos with the goal of proposing an expanded set of marine protected areas.

Using divers and an underwater robot, the crew documented the biodiversity in the waters off every country bordering the Baltic. The team covered more than 7,000 nautical miles and completed more than 130 dives. Oceana is planning a follow-up expedition in the spring of 2012.
