Scripps Oceanography researcher’s assertion bolstered by series of new studies. New research lends credence to an unorthodox retelling of the story of early Earth first proposed by a geophysicist at Scripps Institution of Oceanography at UC San Diego. In a study published on March 15, 2021, in the journal Earth and […]

A humpback whale. The songs of fin whales can be used for seismic imaging of the oceanic crust, providing scientists a novel alternative to conventional surveying, a new study published this week in Science shows. Fin whale songs contain signals that are reflected and refracted within the crust, including the sediment and […]
