The federal Interagency Working Group on Ocean and Coastal Mapping recently released the sixth annual report on progress made in mapping U.S. ocean, coastal, and Great Lakes waters. To safeguard our national security and economic prosperity, ocean mapping, exploration, and characterization is foundational to maritime commerce, domestic energy and seafood production, tourism and recreation, and understanding of our natural resources, among other interests. The 2020 National Strategy for Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone (NOMEC) makes comprehensive ocean mapping a priority for the coming decade. The Unmapped U.S. Waters report tracks progress toward these important goals.

On January 29, 2025, a commercial jetliner and a U.S. Army helicopter collided in midair over the Potomac River, near Washington’s Ronald Reagan National Airport. On February 2, the U.S. Coast Guard and District of Columbia Fire Department requested NOAA Coast Survey’s expertise in hydrographic surveying in order to locate wreckage from the incident using multibeam and side scan sonar technology. Once Coast Survey arrived, the incident command team turned over virtually all survey operations, particularly in the shallow water debris field, to our field units.

As we look ahead to continued progress in 2025, NOAA’s Office of Coast Survey is proud to share some highlights of the past year with you. We mounted successful emergency responses to reopen ports quickly and safely after hurricanes and a bridge collapse; completed a five-year process to transition to fully electronic navigational chart production; provided hands-on learning experiences for students aboard NOAA Ship Nancy Foster; and much more, all in service of delivering authoritative ocean and lakebed mapping information as the nation’s chartmaker.

The Hydrographic Survey Specifications and Deliverables document contains the technical specifications for hydrographic survey data submitted to the Office of Coast Survey. It represents NOAA’s implementation of the International Hydrographic Organization standards for hydrographic survey and product specifications. Coast Survey is proud to announce the launch of the new Hydrographic Survey Specifications and Deliverables for 2024, the largest overhaul of the document in more than 20 years.

By Riley O’Connor
In November 1633, the Ark and the Dove set sail from the Isle of Wight—an island off the south coast of England—carrying English and Irish settlers bound for the new colony of Maryland. By January 1634, both vessels arrived at the Island of Barbados and began heading for the colony of Maryland. These settlers sailed into the Chesapeake Bay, the Potomac River, and eventually, the St. Mary’s River. They stopped roughly 12 miles (19 km) northwest from Point Lookout, where the Potomac River enters the Chesapeake Bay. This group of settlers would go on to found Maryland’s first European settlement and future provincial capital, St. Mary’s City.

The federal Interagency Working Group on Ocean and Coastal Mapping (IWG-OCM) has released the fourth annual report on progress made in mapping U.S. ocean, coastal, and Great Lakes waters. Knowledge of the depth, shape, and composition of the seafloor has far-reaching benefits, including safer navigation, hazard mitigation for coastal resilience, preservation of marine habitats and heritage, and a deeper understanding of natural resources for sustainable ocean economies. The 2020 National Strategy for Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone (NOMEC) and the Nippon Foundation-GEBCO Seabed 2030 Project make comprehensive ocean mapping a priority for the coming decade. The Unmapped U.S. Waters report tracks progress toward these important goals.

NOAA hydrographic survey ships, navigation response teams, and contractors are preparing for the 2023 hydrographic survey season. 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. Visit our “living” ArcGIS StoryMap to find out more about our mapping projects and if a hydrographic vessel will be in your area this year!

In 2022, NOAA and NOAA contractors will survey U.S. coastal waters and beyond, including multiple missions in the Great Lakes. As the volume, value and size of marine vessels in U.S. waters continues to grow, it is essential that NOAA increase the accuracy and frequency of surveys. A great amount of data on nautical charts of the Great Lakes is more than 50 years old, and only about 5 to 15 percent of the Great Lakes are mapped to modern standards using remote sensing methods such as light detection and ranging and sound navigation and ranging.

On March 26, NOAA Ship Rainier set sail from Honolulu, Hawaii on a 3,307-nautical mile expedition to the Western Pacific. Originally planned for 2020, this will be the ship’s first multidisciplinary expedition to Guam and the Commonwealth of the Northern Mariana Islands. This collaborative mission between NOAA’s National Ocean Service and National Marine Fisheries Service will deliver high‐quality data, data products, and tools to the region including a seamless map linking hilltops to underwater depths and integrated data on the surrounding coral reef ecosystems. These data can provide information for countless users to make critical management decisions within disciplines such as habitat management and restoration, tsunami modeling, monitoring, and marine resource management.
