Some Corals Survived A-Bombs, Others Didn’t

Fifty years ago the last atomic bomb test shook the Pacific’s Bikini Atoll. Now corals are flourishing here again—though with 42 fewer species than prior to the bomb blasts. At least 28 of the missing corals appear to be genuine local extinctions, victims of the 23 bombs exploded at Bikini between 1946 and 1958. An international team has been surveying biodiversity at the atoll, including diving into the 1954 Bravo Crater, site of the most powerful American atomic bomb ever exploded (15 megatons, 1,000 times bigger than Hiroshima). The Bravo bomb vaporized three islands, raised water temperatures to 100,00 degrees F, shook islands 125 miles away and left a crater 1.25 miles wide and 240 feet deep.

The 1946 point of view.

“The missing corals are fragile lagoonal specialists—slender branching or leafy forms that you only find in the sheltered waters of a lagoon,” says Zoe Richards of the Australian Research Council Centre of Excellence for Coral Reef Studies and James Cook University. Bikini Atoll has been unpopulated and largely unvisited in the decades since the blasts, and reveals how in the absence of more modern stressors like overfishing and overpopulation some corals have the capacity to recover from vast upheavals. Because of its incredible history and current undisturbed character, Bikini Atoll is now the focus of an ongoing effort to list the northern Marshall Island atolls as a World Heritage Site.

Hope the US is spearheading and funding that effort. Seems the least we can do.

AN IMPORTANT UPDATE

We’re falling behind our online fundraising goals and we can’t sustain coming up short on donations month after month. Perhaps you’ve heard? It is impossibly hard in the news business right now, with layoffs intensifying and fancy new startups and funding going kaput.

The crisis facing journalism and democracy isn’t going away anytime soon. And neither is Mother Jones, our readers, or our unique way of doing in-depth reporting that exists to bring about change.

Which is exactly why, despite the challenges we face, we just took a big gulp and joined forces with the Center for Investigative Reporting, a team of ace journalists who create the amazing podcast and public radio show Reveal.

If you can part with even just a few bucks, please help us pick up the pace of donations. We simply can’t afford to keep falling behind on our fundraising targets month after month.

Editor-in-Chief Clara Jeffery said it well to our team recently, and that team 100 percent includes readers like you who make it all possible: “This is a year to prove that we can pull off this merger, grow our audiences and impact, attract more funding and keep growing. More broadly, it’s a year when the very future of both journalism and democracy is on the line. We have to go for every important story, every reader/listener/viewer, and leave it all on the field. I’m very proud of all the hard work that’s gotten us to this moment, and confident that we can meet it.”

Let’s do this. If you can right now, please support Mother Jones and investigative journalism with an urgently needed donation today.
