New data will update nautical charts around the country.
U.S. waters cover 3.4 million square nautical miles, including a sea floor that is constantly changing due to storms, erosion, and development. To keep the nation's suite of over a thousand nautical charts up to date, the Office of Coast Survey annually plans hydrographic survey projects to measure water depths and identify new navigational hazards. Survey planners consider requests by marine pilots, port authorities, the U.S. Coast Guard, the boating community, and others when setting the year's schedule.
Planned 2016 Survey Projects
Maine: Penobscot Bay, most of which hasn't been surveyed since the 1950s, will get its first modern NOAA multibeam echo sounder survey, to acquire data for needed chart updates.
Massachussetts: Buzzards Bay is the subject of a multiyear project for updating charts. 2016 is the third year, and the survey ship will validate U.S. Geological Survey interferometric survey data for charting, and will align with National Geodetic Survey LIDAR data.
Maryland, Virginia: Chesapeake Bay is also the subject of a multiyear survey project for updating charts. NOAA Ship Ferdinand Hassler will work offshore, while launches from NOAA Ship Thomas Jefferson will survey in the vicinity of Hampton Roads concurrent to the ship's maintenance period in drydock.
North CarolinaWilmington survey project will support the U.S. Coast Guard Atlantic Coast Port Access Route Study.
Georgia: Savannah needs hydrographic survey data for the port deepening project in preparation for post-Panamax ships.
Louisiana: Sabine will have a continuation of last year's project to survey part of the approaches to Port Arthur and Calcasieu. Atchafalaya will have a continuation of last year's project to survey part of the approaches to Morgan City. Approaches to SW Pass will be surveyed at the request of the U.S. Coast Guard and Bureau of Ocean Energy Management, to provide new chart data for consideration of a proposed anchorage area near Port Fourchon.
Mississippi: Chandeleur Sound will have surveys to acquire critical updates since Hurricane Katrina.
Alaska: Yukon River will be partially surveyed to validate a new charting approach using satellite-derived bathymetry. Etolin Strait will also validate satellite-derived bathymetry data, as well as establish a survey corridor behind the island. This project will provide data for some of the new charts identified in the U.S. Arctic Charting Plan. Dutch Harbor will benefit from a shore-based survey operation simultaneous with a NOAA Fishpac project, as the ship's smaller launches will acquire more data at the site of the 2015 M/V Fennica grounding. Kodiak Island will have another year of a multiyear surveying campaign in this critical area for increasing fishing and tourism. Prince of Wales Island needs updated survey data to improve charts to Tlevak Strait, expanding to Sukkwan Strait and Howkan Narrows. Behm Canal will get its third (and final) year of survey work to circumnavigate Revillagigedo Island as well as George and Carol Inlet, Alaska.

2016 hydrographic surveys will be conducted by NOAA's four dedicated survey ships—Thomas Jefferson, Ferdinand Hassler, Rainier, and Fairweather—and private companies that survey on a contract basis with NOAA. The NOAA ships are operated and maintained by the Office of Marine and Aviation Operations, with hydrographic survey projects managed by the Office of Coast Survey.
