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.Continue reading “NOAA searches for dangers to navigation following Hurricane Dorian”

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.Continue reading “NOAA completes hydrographic surveys following Hurricane Barry”

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.Continue reading “From historic air disasters to hurricane response, NOAA uses cutting edge science to survey the seafloor”
Ever wonder what it’s like to be a member of the NOAA Coast Survey team? We use the Coast Survey spotlight blog series as a way to periodically share the experiences of Coast Survey employees as they discuss their work, background, and advice.

“Once I saw the mission I was hooked. It was the best job a recent graduate who loved being in the field could ask for, especially when you get to travel all around the country. Where else could I practice my love for science, utilize my education, solve real world problems that serve a purpose, and directly impact people in a positive way?”
After quickly gaining the strength of a Category 4 storm, Hurricane Michael reached the panhandle of Florida on Wednesday, October 10. With maximum sustained winds of 155 mph and storm surge reaching 15 feet, this storm wiped out coastal communities and closed ports to all traffic in the area. Dangerous winds and storm surge can shift sands and pull large objects beneath the waves, creating hazards to navigation. Before ports can reopen and safely resume vessel traffic, the U.S. Coast Guard must be aware of any underwater dangers so they can either be properly charted or removed.

Almost one year following the passage and destruction of Hurricane Maria, NOAA Ship Thomas Jefferson has returned to Puerto Rico. Following the storm, Thomas Jefferson deployed in September 2017 for hydrographic hurricane response work in Puerto Rico and the U.S. Virgin Islands (PR/USVI). The ship and crew surveyed 18 individual port facilities to ensure safety of navigation and help re-open the region for maritime commerce. Thomas Jefferson’s second major project of 2018 has brought the ship back to Puerto Rico from August to November, conducting follow-up survey work along the north and south coasts.

“But, sir, what does the country want in the coast survey? They want a very useful work done, a very important work done, and they want it done in the best manner.” – U.S. Senator John Davis (MA), 1849, explaining the importance of the coast survey to safety and the U.S. economy during the 30th Congress, 2nd Session
As the nation’s nautical chartmaker, NOAA Coast Survey provides critical emergency response information to coastal communities and waterways. Each year, Coast Survey prepares for hurricane season in order to perform the work in—as the late Senator Davis put it—“the best manner.” Last year’s string of powerful hurricanes underscored the importance of coordinated efforts for storm preparation, response, and recovery. With the official start of the 2018 hurricane season just around the corner, Coast Survey’s regional navigation managers spent the large part of April and May meeting with U.S. Coast Guard (USCG), port authorities, NOAA National Weather Service, and communities to prepare emergency response capabilities.

NOAA’s Office of Coast Survey is the federal leader in emergency hydrographic response. Consecutive strong storms during the 2017 hurricane season made response efforts challenging, and emphasized the importance of having a well-trained and versatile staff. Coast Survey’s regional navigation managers, navigation response teams (NRTs), and mobile integrated survey team (MIST) worked with partners before and after the storms to quickly and safely reopen ports and waterways.
The MIST equipment is a mobile, quick-install side scan and single beam sonar kit that can be quickly set up on a vessel of opportunity. Recently, Coast Survey sent the MIST team to Astoria, Oregon to conduct a hydrographic survey of the Mott Basin area, which the U.S. Coast Guard (USCG) requested to confirm charted depth and obstruction data. Continue reading “NOAA mobile integrated survey team prepares for hurricane season”
The 2017 Atlantic hurricane season was powerful, with the strongest storms occurring consecutively from late August to early October. The sequential magnitude of four hurricanes in particular—Harvey, Irma, Maria, and Nate—made response efforts challenging for NOAA’s Office of Coast Survey. Coast Survey summarized this season’s response efforts along with the efforts of NOAA Ship Thomas Jefferson (operated by NOAA’s Office of Marine and Aviation Operations) in the following story map.

Hurricane Maria struck the U.S. Virgin Islands (USVI) and Puerto Rico on Wednesday, September 21, as a strong Category 4 hurricane. The storm brought sustained winds of 150 mph and dropped over 18 inches of rain in some areas. Although these islands have seen their fair share of hurricanes and tropical storms, the last storm of this intensity to hit Puerto Rico was the San Felipe Segundo hurricane in 1928. The widespread flooding, winds, and storm surge from Hurricane Maria devastated the islands leaving them without power and their critical ports paralyzed as debris, shoaling, and damaged infrastructure prevents large vessels from entering safely.
