Climate change stories from the abyss: Ancient climate mirrored and influenced by geochemical processes deep within ocean

Posted by & filed under Geology.

Scientists have shed new light on the world's history of climate change. The Pacific Ocean has remained the largest of all oceans on the planet for many million years. Scientists have now recovered 6.3 kilometers of sediment cores from water depths between 4.3 and 5.1 km and drilled 6.3 km of sediment cores at eight locations. The cores offered an excellent archive of Earth's history and showed how global climate development during the past 55 million years is mirrored and influenced by geochemical processes deep within the ocean.
