Scuba Diving the Bikini Atoll
An 11-hour flight from Tokyo and a five-hour flight from Honolulu, Bikini Atoll, the northern most chain in the Marshall Islands is one of the remotest places on earth and therefore an adventure that most divers can’t experience. Consisting of 23 separate islands, it surrounds an 8 km deep lagoon and was known for its rich fishing reefs that supported 40 local families. Before the tests, it was an island paradise.
Brushing aside opposition from the original Manhattan scientists, local inhabitants and animal rights campaigners, local islanders were moved to the nearby island of Kwajalein, with the promise that they’d be able to return in six months. The Navy also wanted to show the survivability of their sailors to nuclear attack. So, they packed $450 million worth of target ships with livestock, including goats, cows and Guinea pigs.
Although spectacular, the results were disappointing. Only five ships were sunk and none of those were the big battleships. The US Navy was quick to point out the sturdiness of their ships, with Secretary of the Navy James Forrestal telling reporters that capital ships were near invulnerable to any hits above the water. Further investigation in fact showed that the bomber had missed its target by almost 700m. Had the bomb exploded over the Nevada as planned, at least nine ships would have been obliterated.
About a month later, the Navy tried again. A similar bomb was suspended 90 feet below LSM-60, an old landing ship and detonated at 08:35. BAKER was everything ABLE wasn’t. Nine ships in total, including two battleships and an aircraft were all wrecked and sunk in the lagoon.
Despite their promises to the islanders, The US military continued to use Bikini Atoll as a nuclear testing ground for a number of years after the 1946 tests, thwarting their return. In 1955’s Operation Castle, the largest ever US nuclear test left the island uninhabitable for decades.
70 years on, the islands have remarkably begun to recover. Marine life seems to be extremely resilient to nuclear radiation and the lagoon is now a haven for coral and rare fish. In fact, recent research has shown that adaptation shown by the local coral could hold some key insights for cancer treatment.
Despite a low-level of persisting radioactivity, the 13 wrecks that sit at the bottom of the lagoon have proved to be a big draw and recreational diving started in 2011. The local government now runs annual expeditions and unsurprisingly, the massive 36,000 ton USS Saratoga is the biggest attraction, sitting upright and almost perfectly preserved.
