Deep-water Deployment

WHOI engineers Jim Ryder (center) and Mark Anderson (right) assist the U.S. Antarctic Program’s Ross Hein (left) to deploy a scientific mooring at the Ocean Observatories Initiative (OOI) Global Array in the Argentine Basin. Because the four OOI Global Arrays are located in the deep ocean, their mooring lines can be several miles long. This bright orange float contains an acoustic release, a device that can be triggered from the ship to divide the mooring into two parts while it’s still in the water, allowing the mooring to be safely recovered.(Photo by Mitch Elend, University of Washington)
