Microbes that are key indicators of Puget Sound’s health in decline

Paleontologists with the University of Washington’s Burke Museum of Natural History and Culture find that tiny organisms called foraminifera have a big story to tell about the health of Puget Sound. Two recent studies about the health of Bellingham Bay and inlets in the Bremerton area found the diversity and number of foraminifera — single-celled marine organisms that live on the sea floor — deteriorated significantly. The decline of these microscopic organisms is consistent with the deterioration of snails and other larger marine animals, even though analysis showed a reduction of chemical pollutants in Bellingham Bay and Bremerton over the same period of time.
