RV Knorr, made famous by being the Woods Hole vessel that had the researchers that found Titanic aboard, is heading to Mexico. The ship was a mainstay of the Woods Hole Oceanographic Institution since it was delivered to them in 1970. And logged close to a million miles in its long history with Woods Hole. The ship was officially decommissioned in 2014 and its replacement, the RV Neil Armstrong, will take its place. The ship will now serve in the Mexican Navy though it is unclear what her duties will be.
