Another #IronBottomSound #shipwreck we explored during the NA173 expedition, originally discovered by Dr. Robert Ballard in 1992, was the #USSPreston. The 104-meter Mahan-class destroyer was lost in the Third Battle of #SavoIsland on November 14, 1942.

Join our team for the first-ever comprehensive video survey of the #seafloor resting place of the #USSWalke- a Sims-class destroyer that was sunk southwest of #SavoIsland during the Second Naval Battle of Guadalcanal. Watch the highlight video: www.youtube.com/watch?v=4pfS...

During our exploration of #Guadalcanal, we revisited another of Dr. #RobertBallard’s 1992 discoveries: the #USSNorthampton. The 176-meter-long heavy cruiser was lost during the #BattleofTassafaronga, which began on November 30, 1942, southeast of #SavoIsland. www.youtube.com/watch?v=y4Ax...
