Knorr

Since arriving at WHOI in 1970, research vessel Knorr has traveled more than a million miles—the equivalent of forty trips around Earth. During a 1991 overhaul, the ship was cut in half and a 33-foot section added to stretch the vessel to its current length of 279 feet. The added length helps Knorr to support and deploy the Long Core, a unique tool developed by WHOI engineers and scientists that takes 150-foot sediment cores from the seafloor—some of the world’s longest. More photos of WHOI vessels, past and present, are featured in the 2012 WHOI wall calendar.(Photo courtesy of Woods Hole Oceanographic Institution Archives)
