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.

Office of Coast Survey 2024 Year in Review

A group of images showing various activities undertaken by the Office of Coast Survey throughout the course of 2024.

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.
