Gallery: Launching the Remotely Operated Vehicle

Researchers onboard the NOAA Ship Nancy Foster launch a remotely operated vehicle (ROV) into the waters off St. Croix several times a day during the eight day mission. The ROV provides the scientists with "eyeballs" beneath the water to see the health of the ecosystem and to better understand what the ship sonar is capturing with multibeam data.

Once the ROV is safely away from the ship, ROV technician Lance Horn drives the ROV to the seafloor.

Once the ROV is safely away from the ship, ROV technician Lance Horn drives the ROV to the seafloor. Then, he carefully steers the vehicle to within feet from the bottom of the ocean. At the same time, he operates several cameras attached to the ROV. The cameras allow the scientists to take photos and shoot video of the coral reefs and fish on the seafloor.

This short video provides a brief snapshot of operations during a ROV launch. Launching the vehicle typically takes about 30-45 minutes, depending on the depth of the seafloor. Once the ROV is on the seafloor, it may spend several hours exploring.
