On August 27, an international contingent from the United States (NOAA), the United Kingdom Hydrographic Office, and the Canadian Hydrographic Service participated in the S-100 sea trial in Busan, Republic of Korea.
S-100 is the International Hydrographic Organization’s (IHO) Universal Hydrographic Data Model’s framework standard from which a variety of product specifications can be developed for use within navigation systems and marine spatial data infrastructure. For many years, NOAA and the Ministry of Fisheries of the Republic of Korea have had a Joint Project Agreement and one of the projects is to develop and promote and S-100 test bed. This test bed is designed to help further the development of S-100 infrastructure used to develop S-100 related products and further the testing of S-100 interoperability within navigation systems.

Storms, particularly hurricanes, can be unpredictable. Therefore, NOAA’s hydrographic survey response teams that aid in the reopening of ports following storms, are designed to be flexible, proactive, and are on call 24/7 should the need arise to identify dangers to navigation.

For more than 50 years, NOAA Ship Rainier and its hydrographic survey launches have surveyed the Pacific seafloor. During this time, Rainier sailed thousands of miles, including the entire U.S. west coast, Alaska, and Hawaii. This year, Rainier expands on its traditional role of hydrographic survey and is supporting dive operations in the Northwest Hawaiian Islands and in the Papahānaumokuākea Marine National Monument. While Rainier is sailing these remote coral atolls, the survey launches — that are usually in its davits and deployed directly from the ship — are tasked to their own surveys around the islands of Maui, Moloka’i, and O’ahu.

NOAA Ship Rainier field tested a new hydrographic survey platform this season. Last winter, one of the ship’s hydrographic survey launches was converted into a semi-autonomous vessel, allowing it to be operated remotely. Hydrographic surveying is, by nature, dangerous. Autonomous systems have the potential to augment traditional surveying methods, improving efficiency and decreasing (or eliminating) risk to the surveyors themselves. As such, this technology is an exciting step toward fully-autonomous hydrographic survey systems.

NOAA’s Office of Coast Survey, the University of Southern Mississippi (USM), and Saildrone accomplished a key milestone in the research and testing of unmanned technology that can lead to enhanced seafloor mapping capabilities with the launch of the first Saildrone — a wind-driven and solar-powered unmanned surface vehicle (USV) — equipped with multibeam echo sounder technology in the Gulf of Mexico. NOAA anticipates the success of this mission and technical achievement will lead to mapping projects in the Arctic.

Last week, NOAA’s Office of Coast Survey held its third annual Nautical Cartography Open House welcoming over 250 attendees from the U.S. and abroad. Government agencies, industry and academic partners, and members of the public attended. The open house featured posters, presentations, tours, and exhibits centered around four themes: Bathymetric Databases, Custom Charting, Innovative Cartography, and Precision Navigation. Dr. Shachak Pe’eri, organizer of the event and chief of the Cartographic Support Branch in the Marine Chart Division, welcomed attendees in the morning and John Nyberg, chief of the Marine Chart Division, gave the keynote speech.

Seven tropical cyclones in the Atlantic Ocean have been named Barry, with the first storm making landfall in 1983. In 2019, Hurricane Barry reached Category 1 status on July 13, becoming the first hurricane of the 2019 season.
On July 11, Office of Coast Survey’s Gulf Coast Navigation Manager, Tim Osborn, received requests from U.S. Coast Guard, U.S. Army Corps of Engineers, and local ports for resources to confirm navigational depths in Louisiana waters. Once a navigation manager receives requests for hydrographic surveys, Coast Survey formulates logistics to complete these requests. In the case of Hurricane Barry, Coast Survey’s navigation response team (NRT)- Stennis mobilized to respond to Port Fourchon, Louisiana’s southernmost port. Port Fourchon supports significant petroleum industry traffic coming in from the Gulf of Mexico, furnishing about 18% of the U.S. oil supply.

On July 20, 2019, NOAA’s Office of Coast Survey unveiled two new GIS viewers — NOAA ENC® viewer and NOAA RNC® viewer — allowing users to seamlessly interact with NOAA’s various chart products.

Hydrographic surveying continually evolves to improve safety, efficiency, and accuracy in data collection. From using side scan sonar equipment during hydrographic survey response efforts following air disasters in the late 1990s, to recent hurricane response efforts to re-open ports to maritime commerce, our science always strives to be cutting edge.

Navigation response team (NRT)-Seattle continued hydrographic survey work on one of the West’s most relentless rivers, the Columbia. The Columbia River is the lifeblood of the regional economy, expanding far beyond the natural divide it provides between the states of Oregon and Washington.
