David Field’s SIO Ph.D. thesis work on climate change will be published in the journal/ Science/. Field studied fossilized foraminifera from sediment cores collected from the Santa Barbara basin and discovered that plankton populations changed significantly in response to a warming trend that began in the early 1900s. As ocean temperatures increased, subtropical and tropical species of foraminifera (forams) became more abundant. Forams that live in cooler waters decreased, especially after the mid-1970s. These changes are unlike anything seen during the previous 1,400 years. For more information on David’s thesis, please visit: The previous link is a link to Non-Federal government web site.
