About Coast Survey

    President Thomas Jefferson created the U.S. Coast Survey in 1807 to provide nautical charts that would help the young nation with safe shipping, national defense, and maritime boundaries. Two centuries later, Coast Survey – now an office within NOAA – continues to provide navigation products and services that ensure safe and efficient maritime commerce on America’s oceans and coastal waters, and in the Great Lakes.

    Innovative applications beyond navigation emerge as researchers harness evolving technologies. These advancements give Coast Survey tremendous opportunities to help the nation meet the challenges of the changing environment. Applying the newest advancements for survey and detection, data adds to our scientific knowledge of the coastal seafloor. With this knowledge, we can simulate sea level effects on coasts and ecosystems, identify sensitive marine habitats, select alternative energy sites, identify geological hazards, and predict the impact of environmental conditions on species and habitats.

Coast Survey has four divisions

The Hydrographic Surveys Division manages hydrographic, bathymetric, and oceanographic survey activities, including data acquisition and processing in support of the suite of NOAA’s nautical charts.

The Marine Chart Division updates and maintains over 1000 nautical charts, covering 3.4 million square nautical miles of U.S. coastal waters, the Great Lakes, and some U.S. territories. These charts are available in both paper and electronic format.

The Navigation Services Division works directly with marine transportation stakeholders to support commercial and recreational navigation. They deploy mobile response team to survey ports and near-shore waterways, searching for dangers to navigation.

The Coast Survey Development Laboratory develops and improves cartographic, hydrographic, and oceanographic systems. This division helps to provide products and services for the coastal marine community, to support navigation and protect the coast.
