Ocean scientists recommend plan to combat changes to seawater chemistry
Global carbon dioxide emissions are triggering permanent changes to ocean chemistry along the North American West Coast that require immediate, decisive action to combat. That action includes development of a coordinated regional management strategy. Ref. Source 1m.
Marine life quickly recovered after global mass extinction
Reptiles rapidly invaded the seas soon after a global extinction wiped out most life on Earth, according to a new study. The oldest marine reptile fossils appeared 248.81 million years ago, the most precise date yet, according to the study. These pioneering marine reptiles, including the dolphin-like ichthyosaurs and sauropterygians, went on to rule the Mesozoic seas during the era of the dinosaurs. Ref. Source 1b.
Water cooling for the Earth's crust. How deep can seawater penetrate through cracks and fissures into the seafloor? By applying a new analysis method, an international team of researchers has now discovered that the water can penetrate to depths of more than 10 kilometers below the seafloor. This result suggests a stronger cooling effect on the hot mantle. Source 5q.
