Seawater Chemistry May Have Influenced the Exchange of Elements Between Oceans and Earth throughout History
New research from scientists within the Earth and Environmental Sciences Area at Berkeley Lab and others at UC Berkeley indicates that changes in the composition of seawater during the past 500 million years may have previously unrecognized effects on the composition of hydrothermal fluids flowing back into the oceans throughout millions of years. scientists may have previously overestimated the amount of weathering and erosion – the removal of material from land – needed from rivers to change the ocean’s composition over geologic time.
