MARINE CORPS BASE HAWAII (Jan. 26, 2016) -- Divers from the U.S. Army’s 7th Dive Detachment ready their dive gear and rib boat before heading out into the waters of Kaneohe Bay to conduct a dive survey for the U.S. Army Corps of Engineers, Honolulu District in support of a Navy Dept. financed structural study of the historic Seaplane Ramps at Marine Corps Base Hawaii (MCBH) on Kaneohe Bay. The study, being conducted in-house by the District, provided an opportunity for the Corps to partner with the Army’s 7th Dive Detachment, 84th Engineer Battalion, 130th Engineer Brigade, which conducted the two day underwater site survey this week.
