Monitoring the Gulf through ROV Technology

The "Jewels of the Gulf: Deepwater Expedition" led by chief scientist Iliana Baums, associate professor of biology, used the Global Explorer ROV outfitted by Oceaneering to capture hundreds of still images of corals that have been monitored yearly since the Deepwater Horizon oil spill in 2010.

Global Explorer ROV
The "Jewels of the Gulf" deep-sea expedition used the Global Explorer, a remotely operated vehicle outfitted by Oceaneering, to take images of deep sea corals and their surrounding areas for monitoring purposes. Remotely operated means that the vehicle is tethered to the ship with a long fiber-optic cable, and operations are controlled by skilled pilots on shipboard while the ROV is deep in the ocean. About the size of a mini-van, the Global Explorer has a seven-function manipulator arm, which can be used to gently collect organisms for further analysis.
