NOAA’s nowCOAST improves BlueTopo access

A screen capture of the BlueTopo data layer displayed in NOAA's nowCOAST showing the entrance to Long Island Sound.

NOAA’s Office of Coast Survey produces and maintains several types of data models and products, from operational forecast systems to nautical charts. One of these models comes from the office’s National Bathymetric Source, or NBS, program which creates and maintains high-resolution bathymetry composed of the best available data. Bathymetry is a term that refers to the depths and shapes of underwater terrain and is a visualization of the “beds” or “floors” of water bodies, including the ocean, rivers, streams, and lakes. This data model is available to the public in a product called BlueTopo.

The National Oceanic and Atmospheric Administration is pleased to announce a partnership with the City of Valdez for a hydrographic surveying project in Port Valdez. This project was selected for the Brennan Matching Fund from last year’s round of applicants and is slated to occur in 2025. The project will provide high resolution bathymetry and backscatter data over approximately 32.5 square nautical miles, and supply a contemporary baseline to help city emergency managers understand and prepare for potential impacts of submarine landslides.

The Office of Coast Survey’s ongoing response to the Francis Scott Key Bridge disaster

An image of the largest outbound vessel in the Fort McHenry Channel since the Francis Scott Key Bridge collapse.

On Tuesday, March 26, 2024, the 984-foot M/V DALI allided with the Francis Scott Key Bridge near Baltimore, Maryland, sending the bridge tumbling into the Patapsco River, resulting in the tragic loss of six construction workers, and triggering a local, state, and federal response. Large sections of the bridge’s structure lay across the main shipping channel into the Port of Baltimore closing the deepest shipping lane into and out of the port, and resulting in an estimated loss of $15 million in daily economic activity for the area. All shipping traffic was diverted from the area, enabling first responders to conduct high-priority rescue and recovery operations and allowing highly trained salvage crews to begin the arduous task of removing bridge wreckage. Due to the amount of debris in the water, it was evident that salvage operations would take some time, and the priority at the time was to open the port for at least some vessel traffic.

The members of the federal Interagency Working Group on Ocean and Coastal Mapping (IWG-OCM) are thrilled to announce the release of the first Standard Ocean Mapping Protocol (SOMP)! The SOMP is a standardized technical protocol for acquisition, processing, and archiving of ocean and coastal mapping data. It was developed in support of National Strategy for Ocean Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone (NOMEC) goals and is built from existing standards and best practices developed by the ocean and coastal mapping community.

Technical specifications for submitting hydrographic survey data get an overhaul

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.

NOAA’s 2024 hydrographic survey season is underway

An image of survey vessel operating near Pago Pago Harbor, American Samoa.

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. 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!

Surveying the Canadian Arctic aboard the icebreaker Henry Larsen

Annie Raymond, a member of one of NOAA’s navigation response teams, spent time in late summer aboard Canadian Coast Guard (CCG) icebreaker Henry Larsen in the Canadian Arctic with the Canadian Hydrographic Service (CHS). Her time aboard the ship was part of an exchange program designed as an opportunity for the Office of Coast Survey and CHS to gain exposure to each other’s field operations, particularly highlighting challenges for Arctic operations. Throughout the experience, she observed similarities and differences between Coast Survey and CHS data acquisitions and operations.

NOAA contributes to Empowering Women in Hydrography through at-sea experience, part 6

An image of NOAA Ship Nancy Foster.

The Empowering Women in Hydrography project is a global effort led by the International Hydrographic Organization and Canada that seeks to initiate, organize and track a series of activities and initiatives which will enable more women to participate equitably in the field of hydrography and to assume leadership roles within the hydrographic community. NOAA is contributing to the project via an ‘at-sea experience’ on NOAA hydrographic ships for three women each year over the lifespan of the project. After a global call for nominations, three women were selected to join NOAA ships for the 2023 survey season. Lt. Lucía Cattana, from the Argentine Naval Hydrography Service, joined NOAA Ship Nancy Foster from 5 to 10 July 2023, while conducting surveys off the coast of South Carolina.

Surveying the Pribilof Islands, from Pathfinder to Fairweather

Two images of Pathfinder and Fairweather lined up side by side.

By Lt. Taylor Krabiel

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.
