NOAA hydrographic survey ships and contractors are preparing for the 2020 hydrographic survey season. The ships collect bathymetric data (i.e. map the seafloor) to support nautical charting, modeling, and research, but also collect other environmental data to support a variety of ecosystem sciences. NOAA considers hydrographic survey requests from stakeholders such as marine pilots, local port authorities, the Coast Guard, and the boating community, and also consider other hydrographic and NOAA science priorities in determining where to survey and when.

NOAA’s Office of Coast Survey is the nation’s nautical chartmaker, and maintains a suite of more than a thousand nautical charts. Coast Survey is responsible for charting U.S. waters and Great Lakes covering 3.4 million square nautical miles (SNM) of water and 95,000 miles of coastline.
NOAA’s hydrographic survey ships along with hydrographic contractor vessels, recently kicked off the 2019 hydrographic survey season. These surveys not only update the suite of nautical charts, but also help to maintain the safety of maritime commerce, recreational boaters, natural ecosystems, and much more. Operations are scheduled for maritime priority areas around the country and are outlined in Coast Survey’s “living” story map. Here is a list of where they are headed this year:Continue reading “NOAA releases 2019 hydrographic survey plans”
NOAA’s Office of Coast Survey maintains the nautical charts and publications for U.S. coasts and the Great Lakes. This is over a thousand charts covering 95,000 miles of shoreline and 3.4 million square nautical miles of waters. Measuring depths and determining new dangers to navigation in this large area is a monumental job given the seafloor is constantly changing.
One of NOAA Coast Survey’s biggest tasks during the winter months is to plan hydrographic survey projects for the coming field season. Survey planners consider requests from stakeholders such as marine pilots, local port authorities, the Coast Guard, and the boating community, and also consider other hydrographic priorities in determining where to survey and when.

Matthew became a hurricane on Thursday, September 29, and it was soon clear that NOAA’s navigation services would be called into action. Coast Survey knew they would be needed for the maritime transportation system’s rapid recovery operations, to search for underwater debris and shoaling. That Saturday, while Hurricane Matthew was still three days away from hitting Haiti, Coast Survey was already ramping up preparations for assisting with reopening U.S. shipping lanes and ports after Matthew’s destruction. By Monday, as NOAA’s National Hurricane Center zeroed in on a major hit to the southeast coast, Coast Survey’s navigation service personnel began moving personnel and survey vessels for rapid deployment. Calling in survey professionals from as far away as Seattle, teams were mobilized to locations outside of the hurricane’s impact zones, so they would be ready to move in and hit the water as soon as weather and ocean conditions allowed.
On July 21, U.S. Secretary of Commerce Penny Pritzker attended the change-of-command ceremony for NOAA Ship Ferdinand R. Hassler, one of NOAA’s hydrographic survey vessels that collect data for creating the nation’s nautical charts.
At the ceremony, Lt. Cmdr. Matthew Jaskoski assumed command from Lt. Cmdr. Briana Welton, who served as Hassler’s third commanding officer and will become the chief of Coast Survey’s Atlantic Hydrographic Branch. Jaskoski previously served as executive officer for NOAA Ship Fairweather.
Sec. Pritzker’s remarks highlighted Hassler’s contributions since its commissioning just over four years ago, including its completion of 46 hydrographic surveys and the ship’s contribution to re-opening East Coast sea traffic after Hurricane Sandy. She also reminded the officers and crew of the legacy they honor in their contributions to our nation’s coastal intelligence.
Coast Survey has been discovering and marking the locations of underwater dangers since our surveyors took the nation’s first official ocean soundings in 1834. We’ve used or developed all the technological advancements – lead lines, drag lines, single beam echo sounders, towed side scan sonars, and post-1990 multibeam echo sounders – and now we can point to a new major advancement for fast deployment and quick recovery. In February, Coast Survey’s Mobile Integrated Survey Team (MIST) used an autonomous underwater vehicle (AUV) to locate a submerged buoy that was interfering with anchorages in the Chesapeake Bay.
“You and the crew of the HASSLER put us right where we needed to be!” said a confirmation email from the U.S. Coast Guard to NOAA Lt. Ryan Wartick, one of Coast Survey’s navigation managers. “Thanks for the great work!”
The crew of the NOAA Ship Ferdinand R. Hassler (S-250) hosted a change of command on November 5, while moored at its homeport in New Castle, New Hampshire.
In front of the crew and guests – including Rear Adm. Gerd Glang, director of the Office of Coast Survey, and Capt. Anne Lynch, commanding officer of the Atlantic Marine Operations Center – Lt. Cmdr. Briana Welton accepted command of Hassler, replacing Cmdr. Marc Moser.
Welton is the new survey ship’s third commanding officer.
The 2014 hydrographic survey season is underway, with the NOAA fleet beginning its projects for this year.
Have you ever wondered how Coast Survey goes about determining where to survey and when? Several considerations go into prioritizing survey plans, which are laid out several years in advance. Coast Survey asks specific questions about each potential survey area.
- Is it considered a critical area? If so, how old are the most current survey data?
- Have local pilots or port authorities submitted reports of shoaling, obstructions or other concerns?
- Does the U.S. Coast Guard or other stakeholders from the maritime community (e.g., fisheries, energy, pipelines) need surveys for economic development or ecological protection?
Coast Survey’s 2014 projects reflect these priorities.
In a step towards greater efficiency in NOAA’s hydrographic surveying, experts onboard the NOAA Ship Ferdinand R. Hassler just wrapped up the first extended testing of Coast Survey’s new bathymetric mapping autonomous underwater vehicle (AUV). From Sept 3 to 13, the vehicle completed ten missions lasting up to 16 hours during day and night, while the ship continued with its assigned hydrographic surveys in the approaches to Portsmouth, New Hampshire.
This AUV is equipped with high resolution seabed mapping equipment similar to the ship’s, including a high accuracy positioning system and multibeam echosounder capable of producing seamless maps of the seafloor.
NOAA’s newest survey ship, the Ferdinand R. Hassler, arrived at her new homeport of New Castle, New Hampshire, earlier this month, and began her first New Hampshire survey project today. Hassler was commissioned in Norfolk, Va., in June 2012. She has been undergoing sea trials, training, and certification, and responded to Hampton Roads’ request for rapid survey assistance after Hurricane Sandy last year.
