Mission: Underwater

Two Remote Environmental Monitoring Units (REMUS) vehicles were stowed on R/V Neil Armstrong before the ship departed on the final leg of a three-leg expedition to service parts of the National Science Foundation’s Ocean Observatories Initiative (OOI) at the Coastal Pioneer Array. The array is located at a frontal boundary in the ocean where coastal and offshore waters meet and mix. During the cruise, WHOI engineer Amy Kukulya sent these vehicles on a trial mission, during which they traveled autonomously 45 kilometers along the edge of the shelf and dove hundreds of meters to collect information on ocean current circulation.(Photo by Ken Kostel Woods Hole Oceanographic Institution)
