In a first, scientists have discovered the remnants of seawater dating back to the Ice Age, tucked inside rock formations in the middle of the Indian Ocean.
About:
Researchers from the University of Chicago, using the ship, the JOIDES Resolution, have discovered the remnants of seawater dating back to the Ice Age, while exploring the limestone deposits that form the Maldives.
This seawater from ice age is back salty — much saltier than normal seawater.
Previously, researchers had to reconstruct seawater from the last Ice Age from indirect clues, like fossil corals and chemical signatures from sediments on the seafloor.
Significance: Scientists are interested in reconstructing the last Ice Age because the patterns that drove its circulation, climate and weather were very different from today’s. Understanding these patterns could shed light on how the planet’s climate will react in the future.
