What’s the weirdest think you’ve found in the ocean?

Several week ago, we tackled this question while discussing the incredible shrinking cups the deep-sea scientists like to decorate and send into the wine-dark deep. While toilets and spam cans and beer bottles make for good headlines and shocking images of how extensive human impacts are on the deep sea, those are far from the strangest objects to grace the sea floor.

By most reasonable metrics, that honor has to go to the many nuclear weapons and nuclear weapon components that have been lost at sea over the last 70 years. While a few high-profile incidents have received tremendous coverage, most incidents remain largely shrouded in secrecy, with only sparse reports available. Which brings us to a question that’s been lodged in my brain for the last month: just how many nuclear weapons are sitting at the bottom of the sea?

A Mark-43 nuclear bomb. One of these is at the bottom of the sea.

This, of course, does not include the many, many, many times the United States has intentionally tested nuclear weapons throughout the Pacific, often while forcibly relocating local communities away for their now-test-site homes or, occasionally, not. This also doesn’t include the rare lost nuclear submarine, who’s payloads and whether or not they carried nuclear ordinance are mostly still classified. And, of course, it doesn’t include the Soviets or any other non-US nuclear nation.

For the most part, the 1950s and 60s were a hell of a time for losing track of nuclear weapons. By the time the 70s rolled around we had decide that maybe we should be a bit more careful with these things. But by then, we had accidentally dropped at least ten nukes into the ocean in eight different incidents. And we had lost one in a Carolina swamp. And we had almost accidentally nuked Greenland.

Who the heck thought these things were a good idea?
