R/V Revelle

The Research Vessel (R/V) Revelle named after Roger Revelle, was build in 1996, is roughly 273 ft long (nearly the length of a football field!), and can travel at speeds of 10-19 knots. It sports 6 engines, 2 rear propellers, and a bow thruster that allows for dynamic positioning. Dynamic positioning allows the ship to stay still at one location anywhere in the middle of the ocean for hours. The ship can also move sideways, and spin in a circle on axis at 4 knots. The Revelle has about 23 fulltime crew members who maintain the ship and assist scientists in their research. See the live link for the R/V Revelle for our current position, ship track, and live webcam pictures (refreshed every 10 minutes).
