NOAA Expedition Marks Twelve Years of Discovery in the Caribbean

From March 28-April 7, NOAA scientists will lead the 12th year of an expedition to map the sea floor habitats and identify fish populations in portions of the U.S. Virgin Islands, putting NOAA one step closer to developing comprehensive habitat maps for the territory.

The team will deploy state-of-the-art technology including acoustic sonars, gliders and remotely operated vehicles complete with high-definition cameras from the NOAA Ship Nancy Foster to reach their goals. Much of the work will take place along the southern coast of St. Croix and off the northwest coast of St. Thomas, U.S. Virgin Islands. Efforts will also focus on two coastal areas important to commercial snapper fishing.

Along the way, the scientists will connect with local school groups, lawmakers, and marine resource managers to share their findings. They'll also highlight the strong partnerships NOAA has in the territory to support marine resource management and ocean planning in the U.S. Caribbean where so many communities and economies are tied to the ocean.
