Iron Bottom Sound, Redux
The Corps of Exploration aboard the E/V Nautilus has been continuing Bob Ballard’s work by revisiting Guadalcanal, where Ballard and company discovered numerous wrecks from the 1942-43 naval clashes there—this time with much better cameras and gear than in 1992.
Nautilus has been using the USV DriX, a 25-foot vessel carrying an EM712 multibeam sonar to map the seafloor,
While the dives have been conducted by the ROV Hercules, which features a new model Kraft Predator manipulator with seven-function control, over 79 inches of reach, and a lift capacity of 500 pounds. They usually have smaller “buddy” ROVs too, Argus and Atalanta.
In recent days, they have posted amazing videos of the bow that was shot off the heavy cruiser USS New Orleans (CA-32), the wreck of the USS Northampton (CA-26) which was lost in November 1942 during the Battle of Tassafaronga off Savo Island, the shattered hull of the USS Vincennes (CA-44) and USS Astoria (CA-34) lost at Savo island in August 1942, and one of the “long lancers” themselves, the Japanese Akizuki class destroyer Teruzuki (“Shining Moon”), sent to the bottom on 12 December 1942 in a clash with PT boats.
USS New Orleans (CA 32) comes into the Puget Sound Navy Yard, Bremerton, Washington, for a new bow after battling with Japanese warships in the Southwest Pacific. In this view, she is almost ready for joining to join a new bow. The photograph was released on 11 January 1944. 80-G-44448
