Research vessel Bay Hydro II makes history on Mayland’s Elk River

Situated on the east side of the Chesapeake Bay, 162 nautical miles above the Virginia Capes, Elk River is the western approach to the Chesapeake and Delaware Canal. The canal is one of the busiest waterways in the country. It connects the Chesapeake and Delaware Bays, servicing the ports of Baltimore, Wilmington, and Philadelphia. The U.S. Army Corps of Engineers regularly surveys the dredged channels in the approaches and in the canal, but they are not responsible for the remaining waters of the Elk River. The Elk River was last surveyed in the early 1900s, making depths on the nautical chart close to 100 years old! As a result, NOAA R/V Bay Hydro II was tasked to conduct a modern hydrographic survey of Elk River in Spring 2023.

The Interagency Working Group on Ocean and Coastal Mapping announces progress report on mapping U.S. ocean, coastal, and Great Lakes waters

The federal Interagency Working Group on Ocean and Coastal Mapping (IWG-OCM) has released the fourth annual report on progress made in mapping U.S. ocean, coastal, and Great Lakes waters. Knowledge of the depth, shape, and composition of the seafloor has far-reaching benefits, including safer navigation, hazard mitigation for coastal resilience, preservation of marine habitats and heritage, and a deeper understanding of natural resources for sustainable ocean economies. The 2020 National Strategy for Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone (NOMEC) and the Nippon Foundation-GEBCO Seabed 2030 Project make comprehensive ocean mapping a priority for the coming decade. The Unmapped U.S. Waters report tracks progress toward these important goals.

NOAA releases 2023 hydrographic survey season plans

An image showing all NOAA hydrographic survey vessels.

NOAA hydrographic survey ships, navigation response teams, and contractors are preparing for the 2023 hydrographic survey season. 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. 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!

3D Nation Study report, website, and StoryMap now available

The 3D Nation Elevation Requirements and Benefits Study focuses on 3D elevation data on land and under water.

A new StoryMap on the 3D Nation Elevation Requirements and Benefits Study, which was published in September 2022, is now available. Sponsored by the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS), and conducted by Dewberry, the 3D Nation Study documents nationwide requirements and benefits of 3D elevation data both on land and under water. The study also estimates the costs associated with meeting these requirements and evaluates multiple scenarios for enhancing national elevation mapping programs.

NOAA’s Office of Coast Survey Deputy Hydrographer Dr. John Nyberg participated in a State Department Science Fellowship through the U.S. Embassy in Suva, Fiji this past summer. The fellowship’s main goal for the region is to assist in accelerating the use of coastal and marine spatial planning for marine conservation and to deliver a curriculum to support it. Dr. Nyberg was asked to pay particular attention to engaging Kiribati (pronounced Kiribas), home to the Phoenix Islands Protected Area, one of the world’s largest and most important protected areas. The government of Kiribati is in the process of re-evaluating their approach toward managing the area, and one of the primary goals is to encourage the use of marine spatial planning in that process.

NOAA Ship Thomas Jefferson completes productive field season in the Great Lakes

A graphic showing the route NOAA Ship Thomas Jefferson took returning back to Norfolk, Virginia after the 2022 field season.

Although NOAA has a significant presence in the Great Lakes, this is the first time a white-hulled NOAA hydrographic ship has deployed there since the early 1990s. As a result of survey work in the Great Lakes, NOAA Ship Thomas Jefferson surveyed 450 square nautical miles of lake bottom in Lake Erie – an economically important and ecologically sensitive region. The ship also surveyed 274 square nautical miles in Lake Ontario in October. In both lakes, there were 42 confirmed and new shipwrecks identified along with 22 additional features!

NOAA contributes to Empowering Women in Hydrography through at-sea experience, part 3

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 four year lifespan of the project. After a global call for nominations, three women were selected to join NOAA ships for the 2022 survey season. Firosa Tomohamat from Suriname’s Maritime Authority, joined NOAA Ship Thomas Jefferson from August 8 to 26, 2022 while surveying the Great Lakes.

By Hydrographic Assistant Survey Technician Sarah Thompson

April 10, 2022 marked the beginning of NOAA Ship Thomas Jefferson and her crew’s field season and transit up through the St. Lawrence River, Lake Ontario, and into Lake Erie. This field season, Thomas Jefferson’s base of operations will be in Cleveland, Ohio and has the distinction of being the first NOAA ship to survey the Great Lakes in over 30 years. On the way, Thomas Jefferson had the opportunity to respond to a U.S. Coast Guard request to survey and obtain modern bathymetry on Pollock Rip Channel off the Massachusetts coast.

Ocean and coastal mapping matching fund opportunity

The Office of Coast Survey invites non-federal entities to partner with NOAA National Ocean Service’s ocean and coastal mapping programs on jointly funded projects of mutual interest using NOAA’s geospatial contracting vehicles. Known as the Brennan Matching Fund, the opportunity relies on NOAA’s mapping, charting, and geodesy expertise, appropriated funds, and its authority to receive and expend matching funds contributed by partners to conduct surveying and mapping activities. Partners benefit from this opportunity by leveraging NOAA’s contracting expertise, including its pool of pre-qualified technical experts in surveying and mapping as well as data management to ensure that the mapping data are fit for purpose and are usable for a broad set of purposes, including, for example, safe navigation, integrated ocean and coastal mapping, coastal zone management, renewable energy development, coastal and ocean science, climate preparedness, infrastructure investments, and other activities.
