With over 3.4 million square nautical miles of U.S. waters to chart, NOAA’s Office of Coast Survey is constantly evaluating long-term hydrographic survey priorities. Now, for the first time, Coast Survey is posting its three-year survey plans and making them publicly available at the Planned NOAA Hydrographic Survey Areas (2015-2017) in ArcGIS Online. In addition to seeing the outlines of planned survey areas for the next three years, users can obtain additional metadata (project name, calendar year, and area in square nautical miles) for each survey by simply clicking on the outlines. Other features display the survey area information in a tabular format, and can filter the information using metadata fields.
The Hydrographic Survey Division is Coast Survey’s primary data acquisition arm. They plan and manage the large survey ships’ hydrographic operations. (The Navigation Services Division manages the smaller survey boats used by the navigation response teams. Their survey plans will soon be added to this webmap.)
Because of the enormousness of our area of responsibility and limited resources, Coast Survey develops long-term survey priorities using a number of parameters, including navigational significance, survey vintage (when the area was last surveyed), vessel usage, and potential for unknown dangers to navigation. Coast Survey then culls the long-term priorities for annual survey plans using other factors such as urgent needs (recent grounding, accidents, etc.), compelling requests from the maritime industry and U.S. Coast Guard, traffic volume, and identified chart discrepancies.
While Coast Survey tries to consider operational constraints, ice coverage, and weather patterns while making plans, sometimes the unexpected does occur. We have to emphasize that these are plans, subject to reevaluations, operational constraints, weather, and resource allocation. Because plans often change, people should bookmark the site and check back often. This is an operational site, and we will update plans as they change.
For more information about specific survey areas or to request a survey, please submit an inquiry through NOAA’s Nautical Inquiry & Comment System or contact the regional navigation manager for your area.

Coast Survey Brig Washington
Lt. Thomas R. Gedney, a U.S. Navy officer commanding the U.S. Coast Survey Brig Washington on August 20, 1839, was surveying the area between New York’s Montauk Point and Gardiner’s Island. He “discovered a strange and suspicious looking vessel off Culloden Point, near said Montauk Point,” according to his statement to Connecticut District Court Judge Andrew T. Judson. Gedney and his officers took possession of the vessel. The ship captured by the Washington proved to be the Spanish schooner called L’Amistad – the ship carrying Africans who revolted against their captors and tried to sail back to Africa… Thus began a little known piece of U.S. Coast Survey history. (It is so little known, in fact, that the 1997 movie Amistad did not mention Coast Survey.)
The National Museum of African American History and Culture is presenting a new exhibit of six murals at the Smithsonian’s National Museum of American History. Rising Up: Hale Woodruff’s Murals at Talladega College, portrays the heroic resistance to slavery. Three of the six historic murals on exhibition refer to the slave ship Amistad.
Gedney’s capture of the Amistad was very early in Coast Survey’s history, when naval officers were assigned to command Coast Survey vessels. Gedney was one of the two first senior naval officers attached to the Coast Survey. (The other was George S. Blake.) In 1834, Gedney commanded the Coast Survey’s first hydrographic vessel, the Jersey, and in 1835 discovered the Gedney Channel into New York Harbor. Gedney is also known for tackling the would-be assassin of President Andrew Jackson on January 31, 1835, after the gunman’s pistol(s) had misfired ‒ twice. He reportedly protected the gunman, Richard Lawrence, from the wrath of the crowd so Lawrence could be brought to justice. Gedney joined the Navy in 1815, and died in 1857.
There were two trials on the Amistad: one criminal, for the mutiny; the other was a civil trial, where Gedney et.al. libeled (claimed) as “salvage” the cargo, provisions, cash, and “fifty-four slaves, to wit, fifty-one male slaves, and three young female slaves, who were worth twenty-five thousand dollars.” (See the copies of original documents at the National Archives.)
There were several competing claims for the Africans, involving Queen Isabella of Spain and the two men who said they owned the slaves. If you’ve seen the movie, you know that the case pivoted on the status of the men and women captured on the Amistad. The District Court ruled that the Africans were free individuals; kidnapped and transported illegally, they had never been slaves. Therefore, the court allowed salvage to Lieutenant Gedney and others, on the vessel and cargo, of one-third of the value thereof, “but not on the negroes…”
The Amistad Murals consists of three panels: The Revolt, The Court Scene (pictured here), and Back to Africa. They are normally housed in Talladega College’s Savery Library and are some of artist Hale Aspacio Woodruff’s best known works.
The court ordered President Martin Van Buren to have them transported back to Africa. After going through the appeal process, President Van Buren ordered government lawyers to appeal the case to the Supreme Court. The Supreme Court heard the case, with former president John Quincy Adams arguing against the government and on behalf of the Africans. On March 9, 1841, the Supreme Court ruled in favor of the Africans. They also provided a note on Gedney:
“As to the claim of Lieutenant Gedney for the salvage service, it is understood that the United States do not now desire to interpose any obstacle to the allowance of it, if it is deemed reasonable by the Court. It was a highly meritorious and useful service to the proprietors of the ship and cargo; and such as, by the general principles of maritime law, is always deemed a just foundation for salvage. The rate allowed by the Court, does not seem to us to have been beyond the exercise of a sound discretion, under the very peculiar and embarrassing circumstances of the case.”
In other words, Gedney got his share of the cargo, but not the “slaves” he had also claimed as prizes.

The Amistad murals will be on view at the National Museum of Natural History until March 2015.
A NOAA ship plying the waters off the coast often inspires public curiosity. This is especially true when boaters and others see the ship or her launches just go back and forth, back and forth, all day. It’s not a surprise, then, that NOAA Ship Rainier’s latest project is generating questions from the areas around Protection Island and Lopez Island, Washington.
Don’t worry, there is no problem! NOAA’s Office of Coast Survey is collecting bathymetric data to update nautical charts that are currently displaying depth measurements acquired from surveys conducted from 1940 to 1969. Survey vessels go back and forth, in a maneuver that is similar to mowing the lawn, as they use multibeam echo sounders to measure the depths and to “see” the ocean floor. If any of the vessels discover a danger to navigation – an uncharted wreck or other obstruction, for instance – Coast Survey will immediately inform the U.S. Coast Guard and the information will be relayed to ships and boaters through a Local Notice to Mariners.
NOAA Ship Rainer with her launches aboard
Rainier is one of the NOAA ships dedicated to hydrographic surveys for updating the nation’s nautical charts and other uses. During this project, the ship is using her survey launches to conduct the majority of the survey. Rainier has four 29-foot aluminum boats – each equipped with a high-resolution multibeam echo sounder – that they carry aboard ship. Rainier deploys the launches in the morning to survey, and retrieves them in the evening.
Data acquired by Rainier and her launches will be used to update charts 18465, 18434, 18471, and others, as well as the corresponding electronic navigational charts. (See the full array of charts covering this and other areas, here.) This particular hydrographic survey project, which covers approximately 22 square nautical miles in the Strait of Juan de Fuca, is part of a multi-year project to conduct modern hydrographic surveys and completely update the nautical charts of the waters from Port Angeles to Port Townsend and north to Bellingham, including the San Juan Islands.
This survey project area is a critical priority for updating the charts, since it is near three high-density traffic lanes separated by shoal areas and is frequently transited by large commercial vessels traveling both north to Cherry Point and Vancouver, British Columbia and south to Tacoma and Seattle. The waterways of Puget Sound and the Strait of Juan de Fuca, which have pristine environments, are important for marine transportation, recreation, and national security and defense.
Rainier, with her 50-person crew, commanded by NOAA Commander Edward J. Van Den Ameele, is expected to wrap up the project by late November.
Under beautiful blue skies yesterday in Gulfport, Mississippi, David Evans and Associates, Inc. commissioned its new 82-foot hydrographic survey and scientific vessel Blake. Rear Admiral Gerd Glang, Coast Survey’s director, welcomed the addition to the nation’s hydrographic surveying assets. DEA is under contract to NOAA to provide critical hydrographic data for updating the nation’s nautical charts.

Glang pointed out that, for the past 15 years, NOAA has fulfilled its charting mission through a successful partnership with private sector surveying firms.
“David Evans and Associates, who owns and will operate the Blake, has been an important partner in that effort,” Glang said. “They conducted their first survey for Coast Survey in 1999. In the last 15 years, they have completed 72 hydrographic surveys – nearly 1200 square nautical miles – in the coastal waters and bays of seven different states.”
“David Evans and Associates consistently produces outstanding hydrographic surveys for NOAA. And, they are pioneers in applying new surveying technologies and methods.”
U.S. Senator Thad Cochran, who did the honor of breaking a Champagne bottle across the Blake‘s bow, spoke of the vessel’s value to the nation.
“The survey vessel Blake is an example of the skilled workmanship of our Gulf Coast shipbuilding industry. This vessel will provide an important national seagoing capability to perform valuable research for our state and nation,” Cochran said. “I commend David Evans and Associates, Inc. for its hard work in constructing a world-class research vessel that can serve our nation for decades to come.”
The custom-built Blake is an aluminum catamaran. The vessel is designed to be a stable, efficient and cost-effective survey platform with wave-piercing bows, tier-3 diesel engines, twin 50-kilowatt generators, and a full suite of state-of-the-art survey instrumentation. Built by Geo Shipyard, Inc. in New Iberia, Louisiana, the new vessel will complement the firm’s national operations and expand DEA’s hydrographic and geophysical survey and marine science capabilities in the Gulf of Mexico and beyond.
The new vessel is named after the 19th century U.S. Coast and Geodetic Survey steamer George S. Blake, an oceanographic and hydrographic vessel renowned for testing innovative technologies such as the Pillsbury current meter, which was the first deep-sea current meter, and the Sigbee deep-sea sounding machine. The federal Blake was commissioned in 1874, operated in the Gulf of Maine, the Gulf of Mexico, and the Caribbean Sea. The Blake’s accomplishments are documented in Three Cruises of the BLAKE, by Alexander Agassiz. The vessel had numerous seafloor features named after her, including the Blake Abyssal Plain, Blake Plateau, Blake Canyon and Blake Ridge, all of which are off the southeastern coast of the U.S.
Noting the advanced technologies onboard the S/V Blake, that were not even imagined 140 years ago when the USC&GS steamer Blake did it’s innovative work, Glang congratulated the firm on its significant contribution to the survey mission.
“I look forward to the legacy of accomplishment and innovation that the S/V Blake begins today,” Glang said, “and to a sustained partnership between David Evans and Associates and NOAA.”

From 2005 through today, NOAA Ship Thomas Jefferson has been surveying Long Island Sound, one project area at a time. Some of the area was last surveyed between the late 1800s and 1939. For the 2014 field season, Thomas Jefferson was assigned her final Long Island Sound project, 89 square nautical miles of Eastern Long Island Sound, Fisher Island Sound, and Western Block Island Sound. When this project is complete, we will have resurveyed over 95% of Long Island Sound and all of Block Island Sound with modern survey technology that allows for a complete picture of the seafloor and highly accurate soundings.
This image depicts Thomas Jefferson‘s bathymetry from eastern Long Island Sound to Gardiner’s Bay.
Data acquired by the Thomas Jefferson will update the region’s nautical charts and will serve other users within NOAA, the U.S. Geological Survey, and a New York and Connecticut Long Island Sound Seafloor mapping initiative. The mapping initiative creates products for habitat mapping and geological interpretation, and supports state planning and management of this vital resource.
Bringing the hydrography of this area into modern times has been a huge task, and we appreciate being welcomed as a part of the area’s maritime community! When Thomas Jefferson was asked to participate in the Connecticut Maritime Heritage Festival in New London this summer, the crew was excited for the opportunity to showcase the results of nearly a decade of surveying effort.
On September 12, Thomas Jefferson docked at City Pier, dressed in semaphore flags to welcome crowds lining the pier eager for guided tours. As the sun set, Thomas Jefferson hosted judges and the announcer during the festival’s lighted boat parade. The ship continued to provide tours the next day, and was the highlight of the event for many visitors. More than 500 visitors toured from fantail to bridge, learning about the ship’s mission and hydrographic survey operations, life at sea, and maritime heritage of NOAA and the Office of Coast Survey.
As the festival ended, Thomas Jefferson’s crew cast off from City Pier to return to their Long Island Sound working grounds and continue survey operations. We are excited to return to the survey area and complete the 2014 Long Island Sound mapping project.
