Nancy Foster Mission Cruise Update #1

The Nancy Foster and her crew completed mobilization of the multibeam and ROV equipment while the ship was tied up to the Gordon A. Finch Molasses Pier on the south shore of St. Croix. Mobilization included mounting of the transducer head, which emits and receives the acoustic signal, to the newly fabricated pole.

The Nancy Foster also hosted two groups of local students and teachers. Ten high schools students from various public schools of St. Croix, several elementary students, and 15 teachers/chaperones were given a tour of the ship. The scientific team and ship officers also gave an introduction to the seafloor characterization using multibeam technology, ground truthing the benthic habitats with the Remotely Operated Vehicle (ROV), and history/ecology of the Buck Island Reef National Monument, and a tour of the ship.
