NOAA hydrographic survey ships and contractors are preparing for the 2022 hydrographic survey season in U.S. coastal waters and beyond. 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 considers other hydrographic and NOAA science priorities in determining where to survey and when. Visit our “living” story map to find out more about our mapping projects and if a hydrographic vessel will be in your area this year!Continue reading “NOAA releases 2022 hydrographic survey season plans”

For the first portion of the 2020 field season, NOAA Ship Thomas Jefferson surveyed approaches to Chesapeake Bay. Thomas Jefferson’s 2020 field season consisted of two 45-day “bubble” periods. A “bubble period” is the time a ship closes to personnel transfer while they shelter in place for seven days and undergo COVID-19 testing per NOAA’s Office of Marine and Aviation Operation’s COVID-19 protocol to mitigate exposure. The ship spent the entire first bubble working off the coast of North Carolina and Virginia for this project. These surveys served as a continuation of the ship’s work in the area in the 2019 season. (To learn more about Thomas Jefferson’s work in this area last year, read the 2019 post titled, “NOAA Ship Thomas Jefferson tests innovative DriX unmanned surface vehicle.”Continue reading “NOAA Ship Thomas Jefferson returns to survey approaches to Chesapeake Bay during the 2020 field season”
This week, NOAA’s Office of Coast Survey released the Mapping U.S. Marine and Great Lakes Waters: Office of Coast Survey Contributions to a National Ocean Mapping Strategy. This report is part of NOAA’s ongoing commitment to meet core surveying and nautical charting mandates while supporting broader needs to fill gaps in seafloor mapping and environmental sciences.Continue reading “NOAA Coast Survey’s new strategy supports charting mandates and broader seafloor mapping”

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.
