Here's an object that probably doesn't deserve to be recovered - the head on the Matt Turecamo.Look at the difference between these two shots; the first in 1997, not long after the sinking, and the second in 2000. Hydroids have replaced mussels, and the floor is covered with a foot of silt."Heads" on the Coney Island (top) and Great Isaac (bottom). Courtesy Perry Arts.Head on the Mandy Ray
A fine diagram of a wire-drag operation. The wire is towed between two tugboats, suspended by buoys at a predisposed depth. When the cable snags on an obstruction and draws into a V, the buoys point to its location.
Wire dragging is an operation used to locate and/or reduce the navigational hazard of a sunken wreck, rock, or other obstruction.
