• July 2017:  Research Director - Tim Markowitz, Ph.D.  

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.

  • Public Lecture:  October 11, 2017 at San Francisco Bay Estuary Conference 

Bill Keener will be giving a talk on the Humpbacks of San Francisco Bay at the 13th Biennial Sate of the Estuary Conference in Oakland, CA at 4:20 pm. See http://www.sfestuary.org/soefor details.

  • June 2019:  Golden Gate Cetacean Research Moves to The Marine Mammal Center  

The Marine Mammal Center has announced the addition of a Cetacean Field Research program, led by a team of top researchers formerly from Golden Gate Cetacean Research. A core focus of the program will be to support the extension of protections in San Francisco Bay for cetaceans, or whales, dolphins and porpoises. These efforts will aim to better address the increasing negative human interactions in the urban environment, such as ship strikes, that are threatening whales and other species. Read more about this new program.

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.

News and Updates

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.

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.

Dr. Tim Markowitz, currently teaching at UC Berkeley, has joined Golden Gate Cetacean Research as its Research Director. He brings a wealth of knowledge about the techniques needed to study marine mammals in the wild. His experience in New Zealand from 2009-2012 as the principal investigator analyzing the effects of vessel activity on whale behavior will be especially helpful as we study the influx of humpback whales into San Francisco Bay.
