The force of the blast(s) cannot be imagined. The USS Arkansas, a battleship, has a deep furrow in her hull on the starboard side. This is in a part of the hull protected by three, 12" bands of armor plating! This furrow must be at least 3' deep, and runs for more than 30' as I recall. It is adjacent to a seam than actually opened up, and bunker fuel is still visable. The "wildlife" consists of a considerable variety of fish which actually attracts sport fishermen, who have no interest in diving. Can you imagine? There are also huge coconut crabs which cannot be eaten for the radioactive uptake in their diet of other crabs... There are also sharks in abundance, and Shark Pass is a neat dive if the weather is good, since it is about a one hour trip across the lagoon from the resort, if there is not too much chop. There was no need to chum for these guys... Sharks are also responsible for the serious warning to avoid an early morning or late evening swim off the beach at the resort. We all took that one to heart. Sharks are always present on the dives, and occasionally circle the decompression trapeeze while its occupied. They were NEVER hostile or agressive, however, and only once did I see one with the rigid and extended pectoral fins which means he's pissed. He never got close to me, fortunately. The guy who started the commercial diving operation - Fabio? - reportedly started a night dive, and exited the water in a big hurry after 8 minutes RT. You don't do night dives at Bikini. All in all it is an absolute MUST SEE on the tour...
