NOAA’s 2025 hydrographic survey season is gearing up and will be underway soon

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.

The National Oceanic and Atmospheric Administration’s 2024 hydrographic survey season is ramping up and will be in full swing before too long. For the past few months, NOAA hydrographic survey ships, navigation response teams, and contractors have been diligently preparing for the upcoming field season. The ships and survey vessels collect bathymetric data 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.

NOAA ocean mapping and reef surveys in the Mariana Islands

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.

NOAA releases 2022 hydrographic survey season plans

NOAA Ship Fairweather in College Fiord, Alaska

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.

Deep fiords and hydrographic history in Glacier Bay National Park

By Ensign Alice Beittel and Ensign Karl Wagner

Throughout the spring and summer of 2021, NOAA Ship Rainier surveyed numerous bays and inlets of Alaska’s Glacier Bay National Park and Preserve. As one of the largest national wilderness systems and a United Nations designated World Heritage Site, Glacier Bay National Park includes over 2.7 million acres of marine, terrestrial, and freshwater ecosystems. This dynamic landscape is a living example of a never-ending cycle of geological and ecological change and adaptation. With up to 20-foot tide ranges, seasonal migrations of humpback whales and salmon, and glaciers in flux, the resilient ecosystem attracts millions of visitors each year. This year, Rainier surveyed the Beardslee Islands, Geikie Inlet, Berg Bay, Muir Inlet, Bartlett Cove, Pleasant Island, Taylor Bay, and Dundas Bay. Each survey area revealing several changes in seafloor bathymetry and bottom type. High-resolution seafloor bathymetry will be used to update nautical charts for safe navigation and serve as baseline data to support further research of this culturally and ecologically significant marine environment.

New hydrographic surveying matching fund announced

Update (2/19/21) – Notes and slides from the January 28, 2021, webinar on the NOAA Coast Survey Matching Fund Opportunity are now available.

NOAA’s Office of Coast Survey recently announced a new pilot program for a Hydrographic Surveying Matching Fund opportunity through a Federal Register Notice. The purpose of this notice is to encourage non-federal entities to partner with NOAA on jointly-funded hydrographic surveying, mapping, and related activities of mutual interest. The pilot program relates directly to Coast Survey’s Ocean Mapping Plan and a goal to expand U.S. EEZ mapping by also expanding use of Coast Survey’s hydrographic services contract vehicle.

NOAA Coast Survey’s new strategy supports charting mandates and broader seafloor mapping

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.
