As the 2020 Atlantic hurricane season came to a close on November 30, NOAA’s Office of Coast Survey tallied a few numbers to see what the combined response effort of the navigation response teams, NOAA Ship Thomas Jefferson, and hydrographic survey contractor David Evans & Associates, Inc., looked like.Continue reading “By the Numbers: Coast Survey’s 2020 Atlantic Hurricane Season”
This week NOAA’s Office of Coast Survey concluded its hydrographic survey response following Hurricane Delta. At the immediate request of the U.S. Army Corps of Engineers (USACE), NOAA’s navigation response teams (NRTs) and NOAA Ship Thomas Jefferson surveyed areas within the Gulf Intracoastal Waterway (GIWW), Calcasieu Ship Channel, and the entrance to the channel. With lessons learned from the response to Hurricane Laura — the first major hurricane of the 2020 season and the first hurricane response during a pandemic — the teams and Thomas Jefferson successfully collected, processed, and delivered data to the USACE, identifying significant hazards to navigation and helping to ensure the timely reopening of waterways.Continue reading “NOAA concludes hydrographic survey response following Hurricane Delta”
Hurricane Laura, the first major hurricane of the 2020 Atlantic Hurricane Season, made landfall over Louisiana in the early morning hours of Thursday, August 27. As a Category 4 storm and with maximum sustained winds reaching 150 miles per hour, it caused significant damage along the Gulf coasts of Louisiana and southeastern Texas. For NOAA’s Office of Coast Survey – whose job it is to identify dangers to navigation and help speed the reopening of ports and waterways following severe storms – this marked the first hydrographic survey response effort of the hurricane season.Continue reading “NOAA navigation response teams complete hydrographic surveys following Hurricane Laura”
In anticipation of the temporary closure of the Gulf Intracoastal Waterway (GIWW)’s Inner Harbor Canal Lock, the Office of Coast Survey released three updated NOAA electronic navigational charts (NOAA ENC®) reflecting the Chandeleur Sound Alternate Route and the addition of 97 Aids to Navigation (ATON). The updated charts include US5LA24M, US4LA34M, and US4MS12M and can be viewed in NOAA’s ENC Viewer or downloaded from NOAA’s Chart Locator.Continue reading “Nautical charts reflect alternate route along Gulf Intracoastal Waterway”
NOAA’s Office of Coast Survey, United States Coast Guard (USCG) Sector Honolulu, State of Hawaii Department of Transportation and United States Army Corps of Engineers (USACE) Honolulu Division established a memorandum of understanding (MOU) outlining each signatory’s area of responsibility in the event of a disaster in the Hawaii region. The intent of the MOU is to improve the efficiency and effectiveness of response efforts and speed the reopening of the ports and waterways following an emergency.Continue reading “NOAA joins federal and state partners in signing MOU on emergency maritime response in Hawaii”
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.
