Fresh off a landmark 2025 season in which NOAA Ship Fairweather pushed further north than ever before, the ship launched the 2026 field season just 10 nautical miles from her home port of Ketchikan in southeast Alaska, surveying the approaches to the Revillagigedo Channel.

In celebration of the 250th anniversary of the United States, Sail250 gathered an international fleet of over 60 tall ships and over 40 allied and U.S. naval vessels along the U.S. coast, from May to July. Millions of spectators in New Orleans, Norfolk, Baltimore, New York City, and Boston witnessed this historic maritime celebration. The International Naval Review 250 in the Ports of New York and New Jersey showcased international navies and coast guards in conjunction with the Sail250 event.
While tall ships and naval fleets took center stage, NOAA’s Office of Coast Survey (OCS) worked behind the scenes in the years leading up to the event to ensure safe navigation. Through multi-agency coordination, OCS directly supported this event with hydrographic surveying and accurate charting updates across participating ports.

The winter months represent an end to NOAA’s active survey season. During this period, hydrographic survey ships, navigation response team survey vessels, and contractor teams and vessels undergo maintenance and repair in anticipation of the upcoming survey season. NOAA’s 2025 survey season will begin soon as planned survey projects go through the planning and development process and begin to filter to the forefront of each field party’s focus. The ships and survey vessels 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.

The construction of the Erie Canal was one of 19th Century America’s most significant feats of engineering. Built between 1817 and 1825, the canal provided a water route from Albany to Buffalo, New York, nearly 363 miles to the west. The Canal connected the Hudson River with the Great Lakes via parts of the Mohawk River, through various land cuts and natural lakes. The New York State Public Works Department and the US War Department’s Corps of Engineers began geographically documenting the canal’s route with maps and nautical charts beginning in 1917. The Department of Commerce’s National Oceanic and Atmospheric Administration took ownership of the charts in the early 1970’s and has maintained and updated them for over 50 years. Currently, these charts are undergoing changes to usher them into the digital era of electronic navigational charts.

In the 1950s, U.S. Coast and Geodetic Survey (USC&GS) Pathfinder surveyed the Pribilof Islands with the latest technologies to chart previously unsurveyed waters and bring the islands into a common datum with the mainland. Fast forward 71 years and NOAA Ship Fairweather continues this work. Despite the decades and technologies that separate the two ships, they share many commonalities in their mission and their surveying techniques.

NOAA’s Precision Marine Navigation (PMN) program aims to seamlessly integrate high-resolution bathymetry and high accuracy positioning and shoreline data with the forecast data of water levels, currents, waves, and weather forecasts. This information can be easily accessed and integrated into maritime electronic charting systems and other decision support tools so mariners can plan their transits and make decisions while at sea and coming to and from port. A key component of this program is providing vessel pilots with detailed depth information to ensure safety of vessel transits and that critical under keel clearance safety margins are maintained. Electronic navigational charts, although accurate, typically do not provide the detail that pilots prefer.

Situated on the east side of the Chesapeake Bay, 162 nautical miles above the Virginia Capes, Elk River is the western approach to the Chesapeake and Delaware Canal. The canal is one of the busiest waterways in the country. It connects the Chesapeake and Delaware Bays, servicing the ports of Baltimore, Wilmington, and Philadelphia. The U.S. Army Corps of Engineers regularly surveys the dredged channels in the approaches and in the canal, but they are not responsible for the remaining waters of the Elk River. The Elk River was last surveyed in the early 1900s, making depths on the nautical chart close to 100 years old! As a result, NOAA R/V Bay Hydro II was tasked to conduct a modern hydrographic survey of Elk River in Spring 2023.

On February 14, 2023, NOAA’s Office of Coast Survey released NOAA Custom Chart version 2.0, a dynamic map application, which enables users to create their own paper and PDF nautical charts derived from the official NOAA electronic navigational chart (NOAA ENC®), NOAA’s premier nautical chart product.

NOAA maintains a suite of nearly 2000 electronic navigational charts (NOAA ENC®), as well as the ten volume United States Coast Pilot®. The seafloor and coastline are dynamic environments, which means that our products are constantly scrutinized for possible changes. Each year we make thousands of updates to ENCs, ensuring we are providing the most accurate products possible. The source data for most of these updates comes from NOAA or contractor surveys or from our federal partners, such as the U.S. Army Corps of Engineers and the U.S. Coast Guard. However, we also rely on many other data sources to help keep our ENCs up-to-date.

April 10, 2022 marked the beginning of NOAA Ship Thomas Jefferson and her crew’s field season and transit up through the St. Lawrence River, Lake Ontario, and into Lake Erie. This field season, Thomas Jefferson’s base of operations will be in Cleveland, Ohio and has the distinction of being the first NOAA ship to survey the Great Lakes in over 30 years. On the way, Thomas Jefferson had the opportunity to respond to a U.S. Coast Guard request to survey and obtain modern bathymetry on Pollock Rip Channel off the Massachusetts coast.
