Ironbottom Sound, Naval strait between Guadalcanal and Florida Islands, Solomon Islands.
Ironbottom Sound is a strait between Guadalcanal and the Florida Islands in the Solomon Islands, separating the two landmasses through a deep channel. Underwater slopes drop steeply and the seabed lies more than 200 meters below the surface in many places, while currents run through the narrow passage.
Between August 1942 and February 1943, over 50 warships sank here during several naval battles in the Pacific War. The struggle for Guadalcanal turned this waterway into a focal point of military confrontation in the region.
This stretch of water takes its name from the iron hulls resting on the seabed after the naval campaigns. Fishermen from nearby villages sometimes avoid certain areas where strong currents and submerged wreckage can snag nets or complicate anchoring.
Diving to the sunken ships requires technical training and specialized equipment, as depth and current demand high skill levels. Boat trips across the strait are usually calm, but waves can build quickly when wind picks up.
Destroyers, cruisers and transport ships from both sides rest close together on the seabed, some only a few hundred meters apart. Diving experts report gun turrets and ship bridges that remain visible in the clear water.
