NOAA contributes to Empowering Women in Hydrography through at-sea experience, part 5

A series of images showing Victoria Obura acquiring data on a survey launch, standing on the bridge of NOAA Ship Thomas Jefferson, and preparing to board the survey launch.

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. Victoria Obura, a Hydrographer from Survey of Kenya Hydrographic Office, joined NOAA Ship Thomas Jefferson from 12 June to 23 June 2023, while surveying offshore Galveston, Texas.

By Rebecca Formanek

Staring off into the seemingly infinite blue horizon something inside me asks, what secrets lie beneath the last frontier of this planet? Three weeks aboard NOAA Ship Thomas Jefferson showed me I am not the only one to think this. The talented individuals that comprise the crew of Thomas Jefferson demonstrated the range and dedication to discovering these secrets, and I thank them for sharing their time, knowledge, and experiences. If there is anything that can unite a diverse group of people, it is the sea.

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.

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!

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.

NOAA focuses on the Great Lakes for the 2022 field season

In 2022, NOAA and NOAA contractors will survey U.S. coastal waters and beyond, including multiple missions in the Great Lakes. As the volume, value and size of marine vessels in U.S. waters continues to grow, it is essential that NOAA increase the accuracy and frequency of surveys. A great amount of data on nautical charts of the Great Lakes is more than 50 years old, and only about 5 to 15 percent of the Great Lakes are mapped to modern standards using remote sensing methods such as light detection and ranging and sound navigation and ranging.
