Sea water ... 20,000 years old still exists today
20,000 years ago, life on Earth was much cooler. That was the end of the Ice Age of 100,000 years.
20,000 years ago, life on Earth was much cooler. That was the end of the Ice Age of 100,000 years.
Scientists have studied this stage in Earth's history by looking at things like coral fossils and seabed sediments, but now a group of researchers may have found a base. Just help make it clearer. It was an unbelievably dated ocean water model '20,000 years old ' , taken from an ancient stone block from the Indian Ocean.
Scientists have found seawater dating back 20,000 years.
According to the researchers, this finding represents the first direct remnant of the ocean when it appeared in the last Ice Age of the Earth.
The researchers found extremely rare water samples while drilling sediment cores out of underwater limestone deposits to create the Maldives archipelago in South Asia.
After pulling out each core, the team cut the stone like a powder and put the pieces into a hydraulic press to squeeze out any remaining moisture.
When the researchers examined the composition of the juice samples on the ship, they were surprised to find that the water was extremely salty . Even more salty than today's Indian Ocean.
They have conducted many on-land tests to examine specific elements and isotopes that make up water and all the results do not seem to fit in the modern ocean.
In fact, everything about these water samples shows that they come from a more salty, colder, chlorinated ocean.
"From all indications, it seems quite clear that we now have a real piece of the ocean 20,000 years old," said lead research author Clara Blättler from the University of Chicago.
