Seven tropical cyclones in the Atlantic Ocean have been named Barry, with the first storm making landfall in 1983<\/a>. In 2019, Hurricane Barry reached Category 1 status on July 13, becoming the first hurricane of the 2019 season. <\/p>\n\n\n\n

On July 11, Office of Coast Survey\u2019s 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<\/a> receives requests for hydrographic surveys<\/a>, Coast Survey formulates logistics to complete these requests. In the case of Hurricane Barry, Coast Survey\u2019s navigation response team<\/a> (NRT)- Stennis mobilized to respond to Port Fourchon, Louisiana\u2019s 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<\/a>. <\/strong><\/p>\n\n\n\n\n\n\n\n

Located at the Stennis Space Center, Miss., NRT-Stennis\u2019 Joshua Bergeron and Lt. j.g. Collin Walker prepared the boat, survey equipment, and vehicles as soon as Barry reached the Gulf of Mexico on July 10. Conveniently located in coastal areas around  the United States, NRT\u2019s are able to quickly respond to navigation threats. <\/p>\n\n\n\n

By the time the system developed from a tropical storm to a hurricane, members of Coast Survey’s Navigation Response Branch traveled to Gulfport, Miss., to support survey operations. The team included Michael Bloom from NRT-New London, Lt. j.g. Patrick Lawler from Bay Hydro II<\/em>, and Lt. j.g. Michelle Levano from NRT-Seattle. From there, the team deployed along with NRT-Stennis\u2019 34-foot survey boat to Port Fourchon. Managing storm surge and localized flooding, the team began surveying on July 15. <\/p>\n\n\n\n

As potential dangers to navigation were identified, investigated, and dismissed, the team then shifted their efforts to data collection to charting specifications, utilizing NRT-Stennis\u2019 side scan and multibeam systems onboard. Due to freshwater inflow, tidal storm surge, and tides, the team collected a great deal of sound speed casts. Sound speed casts measure the speed of sound through the water, enabling the equipment and team to know the depth of water to verify their system measurements. <\/p>\n\n\n\n

On July 19, after 100 linear nautical miles of survey, the team packed up and headed to Gulfport to fly back to their respective homeports. NRT-Stennis will process and submit the data to update Port Fourchon nautical charts. <\/p>\n\n\n\n
