Worth pointing out, the image in the article is actually of the 'Great Blue Hole' off the coast of Belize, which is about twice the diameter but half the depth[1] of the one in the paper.

Also quite the opposite of 'recently discovered'; it has been one of the best known diving spots in the world for over 50 years, and one of the very few ocean floor features that I can recognize by eye...
