Johnson, Selenium and Oceans

Posted on 08.23.2015

Tom Johnson, associate professor of geology, and other scientists at the University of Leicester in England are using selenium to investigate how the oxygen content of oceans has changed. The work could provide information about an ocean’s changing oxygen content, which indicates “overall health” of oceans, according to the University of Leicester. Some evidence indicates changing fish populations are associated with variations in oxygen levels in the oceans.
