Monthly Speaker Series
On the second Wednesday of every month, ACS San Diego hosts free lectures that are open to the public. Topics of the lectures are typically related to marine mammals, but not always! Our board members are always looking for future speakers, so if you have a suggestion for a topic, or if you know someone who would be willing to speak to our group, please send us an email!
These presentations are held in person on the Legacy Whale Watch when availableand they continue to be held virtually on Zoom.
For more information on the next speaker and information about attending in person, please visit our Upcoming Speaker page.
Please join us July 10, 2024 at 7:00pm on Zoom for our next speaker series event! For more information, please click here!
Upcoming Virtual and In-Person Lectures:
June 11, 2025 - Thomas Jefferson – “CRUISING THE COAST OF BAJA CALIFORNIA IN SEARCH OF MARINE MAMMALS: A TRAVELOGUE” on the Legacy and Zoom at 7:00 p.m.
Marine Mammal Biologist Tom Jefferson will share his experiences leading whale and dolphin lovers down the Pacific coast of Mexico and up into the Gulf of California on the San Diego-based Searcher. Join us as Tom shares his knowledge and photos from what truly is an extravaganza and celebration of marine life. Come along as we visit calving lagoons of gray whales, experiencing the "friendly whale" phenomenon, and hear about the discovery of "Flue," the hybrid blue/fin whale. Witness Baja's burst of life with blue whales, humpbacks, sperm whales, common and bottlenose dolphins, seabirds and various pinniped species that include northern elephant seals and Guadalupe fur seals, two species that have recovered dramatically from near-extinction. Tom will share his knowledge of the life history of the marine mammals of Baja California, Mexico.
Thomas Jefferson has been studying marine mammals for 40 years, since 1983, and have a Ph.D. degree from Texas A&M University. With co-authors, Marc Webber and Robert Pitman, I published a marine mammal identification guide in 2008: Marine Mammals of the World: A Comprehensive Guide to Their Identification (Academic Press). The second edition was published in 2015. I have done work on a variety of marine mammals, both in southern California and elsewhere. I often work as a naturalist on marine mammal trips in the eastern North Pacific.
