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

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!

Possible Ancient River System Discovered off Wilmington, North Carolina

During the 2023 field season, NOAA Ship Ferdinand R. Hassler was tasked with surveying an area offshore of Wilmington, North Carolina, in the vicinity of Frying Pan Shoals—a dynamic area of dangerously shallow waters. While scientists and crew conducted mapping surveys of the seafloor, they discovered what is believed to be well-preserved ancient remnants of a paleochannel system that could give us a glimpse as to what our North Carolina coastline looked like approximately 20,000 years ago. The location of these newly discovered paleochannels indicates that they may have once been part of North Carolina’s historic Cape Fear River and likely were above sea level during the Last Glacial Maximum.

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.

NOAA Ship Fairweather surveys the remote Pribilof Islands

The Pribilof Islands are remote and isolated, located in the Bering Sea roughly 280 nautical miles north of Dutch Harbor Alaska. The economy and community are reliant on the surrounding ocean, while the islands themselves provide shelter for vessels working in the Bering Sea. Accurate nautical charts are not only integral to safe navigation and delivery of goods and services for the community, but also to commercial fishing and crabbing. The last major survey of the area was conducted from 1951 to 1954 by the U.S. Coast and Geodetic Survey vessel Pathfinder. However, much of the shoreline around St. George remained uncharted. The Fairweather’s surveys of the islands will provide modern bathymetric data for updating NOAA’s charting products in support of navigation safety.
