A bottlenose dolphin has been seen swimming in near Alameda for the past 6 months, often in the vicinity of green bell buoy number "1" off the former Alameda Naval Air Station. Members of a local canoe club, O Kalani, have reported most of the sightings of this animal, which has been given the name Kaimi. We have now taken close-up photos of this dolphin, so that we may be able to track its movements in the future. While the animal's location is unusual, it seems to be doing well so far. If you want to report any of your observations, please use the online form under the "Contact Us" tab on this website. 

  • February 16, 2017:  Jonathan Stern, Ph.D. (1955-2017) 

Dave Ganapoler, GGCR Advisory Board member, moored his 31-foot Camano powerboat in Sausalito today, readying it for research in support of GGCR's porpoise and dolphin studies in San Francisco Bay. The flying bridge will make an excellent observation platform for our bay cetacean surveys.

We mourn the passing of our dear friend and co-founder of Golden Gate Cetacean Research, Jon Stern. An active scientist in the study of marine mammals, he taught in the Biology Department at San Francisco State University.  We were fortunate to have benefitted from his keen intelligence and deep understanding of marine ecology.  His untimely death, at the age of 62, is a great loss for the community of scientists, colleagues and students. We will always remember his spirit, enthusiasm, wit and wisdom.

Jon obtained a B.A. in Biology at Sonoma State in 1980, and an M.A. in Biology at San Francisco State University in 1990, working with the minke whales of Monterey Bay. His study of whales and their roles as marine predators in ocean ecosystems at Texas A&M University earned him a Ph.D. in 1998. With others in the San Juan Islands, he set up the Northeast Pacific Minke Whale Project, which continues to this day. His marine mammal research also interests ranged from killer, pilot, fin, humpback and gray whales, to harbor porpoises, which he discovered had returned to San Francisco Bay. He formerly served as the Conservation Chair for the National Board of Directors of the American Cetacean Society.


To continue his legacy of work on the cetaceans of San Francisco Bay, a "Jonathan Stern Memorial Research Fund" has been created by Golden Gate Cetacean Research. To add your financial support to this fund, please visit the "Donate" page.
