| Sediment cores collected from the seafloor off Southern California suggest that plankton populations in the Northeastern Pacific have changed significantly since the early 1900s, and that the changes closely parallel a general warming trend starting at that time. Oceanographer David Field and his coauthors describe how subtropical and tropical species of small marine organisms called foraminifera (forams) seemed to become more abundant as ocean temperatures increased. |
