Marine Science Sunday Interactive Programs

Join us in person on the second and fourth Sunday of each month for a live program focused on a variety of marine science topics.

Visit our hospital and visitor center in Sausalito, California, to learn more about what The Marine Mammal Center is doing to help save marine mammals found along the California coast and beyond, and learn more about how you can help.

These interactive presentations hosted by our award-winning educators feature multimedia, pictures, video and more to share the stories of amazing marine mammals and the Center’s efforts to ensure the health of these animals and our ocean.

Reserve Tickets

Marine Science Sunday programs are held on the second and fourth Sunday of each month at 10:30am, 12:00pm, and 2:00pm. Each program is 30 minutes.

Anyone can participate in the program, but you must reserve a general admission ticket to visit The Marine Mammal Center that day.

When planning your visit, we recommend arriving at least 30 minutes before the Marine Science Sunday presentation to take advantage of the limited seating. Traffic in the Marin Headlands can get very busy, especially on weekends, so please plan accordingly.

Space is limited and Marine Science Sundays are especially popular, so reserve your tickets today:
