Grand Bay National Estuarine Research Reserve is one of the most biologically diverse ecosystems in the northern Gulf of Mexico. Habitats for sea turtles, bottlenose dolphin, and manatees can be found in the deeper waters of this reserve. Oyster reefs and seagrass beds serve as nursery areas for important marine species such as shrimp, blue crab, speckled trout, and red fish. Credit: Gretchen L. Grammer.

Pendleton Point in Islesboro, Maine. Did you know that Maine has more coastline than California? NOAA's official value for the total length of the U.S. shoreline is 95,471 miles. The NOAA shoreline length calculation was determined by hand in 1939-40 with a recording instrument on the largest-scale charts and maps available at that time. Shorelines of outer coast, offshore islands, sounds, bays, rivers, and creeks were included to the head of the tidewater or to a point where tidal waters narrow to a width of 100 feet. For the Great Lakes, the shoreline lengths were measured in 1970 by the International Coordinating Committee on Great Lakes Basic Hydraulic and Hydrologic Data.
Wells Beach, Maine. The economic benefits of tourism and coastal living contribute billions of dollars to the U.S. Economy. In 2011, the tourism and recreation industry in coastal shoreline counties employed almost three million people and contributed over $282 billion to the U.S. Gross Domestic Product (GDP).
Each year, the Center for the Study of Active Volcanoes at the University of Hawaii at Hilo holds an international training program to assist developing nations in monitoring technologies for potentially active volcanoes. This year, National Geodetic Survey's Francine Coloma shared her expertise in deploying and managing GPS equipment, networks, and related surveying techniques in this humanitarian outreach effort. The program is an international training course in volcano hazards monitoring sponsored by the U.S. Geological Survey's Volcano Disaster Assistance Program. This photo was shot at Holei Pali on the flank of Kilauea volcano on the Big Island of Hawaii.
This stunning panorama of Gambell, located on Alaska's St. Lawrence Island in the Bering Sea, was captured in August, 2014, by NOS's Coast Survey navigation manager in Alaska. NOAA focuses a significant portion of our ocean mapping effort in Alaskan waters because dated nautical charts are inadequate for the increasing vessel traffic in this region. NOAA surveys are essential for providing reliable charts to the area’s commercial shippers, passenger vessels, and fishing fleets.
