Master caption:  Despite the tragic loss, Thresher afforded the Navy an opportunity to evaluate advanced equipment and improve techniques of deep water search and inspection.  Photographs were taken at a depth of more than 8,000 feet with an improved underwater camera-magnetometer device towed by USNS Mizar (T-AGOR-11) and operated from the surface by personnel of the U.S. Naval Research Laboratory.  Visual inspections were conducted and photographs were taken by men aboard the Navy’s remodeled bathyscaph Trieste II.  (2015/11/03).
