Diving Through a Halocline

Beneath a forest in the Dominican Republic, divers explore an underground limestone cave system which has been carved out by water. The water in the cave is exceptionally clear but deep inside the cave system they encounter a rare phenomenon known as a halocline, where fresh water from the cave meets sea water that has seeped inland from the coast, and meet with a beautiful boundary layer.
