NOAA responds to bridge damage near Houston following Tropical Depression Imelda

Overview of multibeam and side scan sonar data overlaid on chart 11329.

While many are aware that hurricanes can inflict costly damage when they make landfall, tropical storms and depressions are not to be underestimated. Tropical Depression Imelda moved over the Texas coast in mid-September producing heavy rain and causing extensive flooding. Nine barges broke free from their mooring on the San Jacinto River and two of these barges hit the Interstate 10 bridge in Lynchburg, Texas. At the request of the U.S. Coast Guard Captain of the Port Houston-Galveston, NOAA’s Navigation Response Team (NRT)- Stennis was called in for rapid hydrographic survey response.

NOAA Ship Nancy Foster performs full-coverage mapping survey of Northern Blake Plateau

ST Barbee and NOAA Affiliate Veronica Martinez deploy Nancy Foster’s Underway CTD.

By Julia Wallace and Lt. j.g. Michelle Levano

NOAA Ship Nancy Foster conducted survey operations offshore of coastal South Carolina from August 12-30, 2019, as a joint effort between NOAA’s Office of Coast Survey and Office of Ocean Exploration and Research. This survey encompassed portions of the Blake Plateau, and was particularly special because this region has never been mapped using contemporary sonar systems. The project served Coast Survey’s mission of providing contemporary data to update nautical charting products and supported the U.S. contribution to Seabed 2030, a multi-national initiative to map the world ocean by 2030. NOAA’s contribution to this project includes providing continuous multibeam survey coverage within the U.S. Exclusive Economic Zone.

UPDATE: The Nav-cast scheduled for 9/26 at 1 p.m. (EDT) is cancelled and will be rescheduled at a later date. We apologize for the inconvenience.

Join us for our next NOAA Nav-cast, a quarterly webinar series that highlights the tools and trends of NOAA navigation services.

NOAA’s nowCOAST: A one-stop-shop for coastal conditions before you head out on the water

NOAA’s nowCOAST (nowcoast.noaa.gov) — a free online interactive map viewer —provides situational awareness on present and future weather and oceanographic conditions for mariners and other coastal users by integrating data from across NOAA and regional observing systems. Users can assess present conditions by creating maps of the latest in-situ weather/marine weather observations, weather radar mosaics, cloud images from GOES weather satellites, and surface wind and sea-surface temperature analyses for the last few hours. Users can also obtain maps of critical weather/marine weather advisories, watches, and warnings, weather forecasts, tropical cyclone track and intensity forecasts, and forecast guidance of water levels, water temperature, salinity, and currents from NOAA oceanographic forecast models.  Users can display these maps using the nowCOAST map viewer or by connecting to its map services. nowCOAST operates in a high-availability hosting facility and is monitored 24 x 7.

S-100 sea trials: working toward harmonized navigation products

International team participating in the S-100 sea trial.

By Julia Powell, deputy division chief of the Coast Survey Development Lab

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.

Hawaiian island surveys will update nautical charts and support habitat mapping efforts

Three of Rainier’s hydrographic survey launches moored in Kahului Harbor, Maui.

By Ens. Lyle I. Robbins

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 successfully field tests autonomous hydrographic survey launch

Autonomous survey launch.

By Lt. j.g. Airlie Picket

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.

Saildrone launched with seafloor mapping capabilities in the Gulf of Mexico shows promise for remote Arctic mapping

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.

NOAA hosts 2019 Nautical Cartography Open House and Chart Adequacy Workshop

Sean Legeer shows a digital cartography display to visiting students.

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.

NOAA completes hydrographic surveys following Hurricane Barry

By Lt. j.g. Michelle Levano

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
