What causes a hole in the ocean?

Exploring blue holes — Researchers believe that blue holes are formed when water floods a previously cavernous region. At the end of the Ice Age, for instance, rising sea levels flooded caves that had been carved out by environmental factors like acidic rain, Discovery reports.

Why is there a hole in the ocean?

Blue holes are submerged springs and sink holes, most of them form in limestone rock, which can be very porous - meaning it has lots of tiny holes in it. Over time, perhaps centuries, water flow erodes the limestone and creates cracks, crevasses and caves leaving a void or an opening.

What's inside the Great Blue Hole?

Researchers consider Great Blue Hole to be the largest of its kind and discovered huge stalactites, dripstone sheets as well as columns inside the blue hole. Water levels in the surrounding areas of the sinkhole are so shallow, where the coral often breaks the surface at low tide.
