That is what an international team …

The Atlantic Ocean did not spring into existence in a sudden tectonic snap; its earliest pulse can now be traced through a set of one-kilometer-long mud waves lying more than 3,000 feet below today’s seafloor some 250 miles west of Guinea-Bissau. New seismic profiles and cores date these colossal ripples to roughly 117 million years old, which shifts the birth …

Ancient Mud Just Shattered a 750,000-Year-Old Ice Myth  SciTechDaily Source link

A new study published in Science Advances is upending decades of scientific belief about the history of the Arctic. Contrary to the long-held theory that a massive, kilometer-thick ice shelf blanketed the Arctic Ocean during the coldest ice ages, new evidence suggests that the Arctic was never fully frozen. By analyzing ancient ocean mud and conducting advanced climate simulations, researchers …
