Bags of sea water dating from the Ice Age have been found within rock formations in the middle of the Indian Ocean.

A team from the University of Chicago made the discovery on a scientific mission during the course of a month exploring the limestone deposits that make up the Maldives.

Through the use of a drill, rock cores are extracted from a deepness ranging from one to three miles below the seabed. Once down, the water is sucked or by means of a hydraulic press the water is squeezed out of the sediments.

Rocks were studied to determine how sediments are formed in the area, which is influenced by the annual cycle of the Asian monsoon. When they extracted the water, they noticed that their preliminary tests were quite salty, much more salty than normal seawater.
