Bodega Marine Lab

The UC Davis Bodega Marine Lab offers free docent-led tours for the public on Fridays 2:00-4:00 p.m. so I went over to check it out.

I remember visiting the lab with my Drake High School marine biology class in the 1970's but it has expanded considerably since then.

Bodega Marine Laboratory (BML), perched above Horseshoe Cove on Bodega Head, is one of the oldest academic marine laboratories in the U.S. Bodega Head has been a field site for researchers and students since the 1920s. The Laboratory was founded in 1960 by UC Berkeley and the first building was completed in 1966. The second building was completed in 1977. BML was transferred to UC Davis in 1983.


Rather than re-word their story myself, I've pasted some copy from their website.

A rare combination of natural and academic assets makes BML a unique marine laboratory. The facility sits on wind-swept headlands in Sonoma County on California's north coast, where a 362-acre coastal reserve meets a state-protected marine reserve. This stretch of ocean is also one of a handful of places in the world where "upwelling," caused by a combination of geography and physics, brings nutrient-rich deep waters to the surface and nurtures a vast array of sea life. This phenomenon makes this coastline among the most biologically productive in North America.

In addition to these remarkable "living laboratories" the Bodega Marine Laboratory is equipped with sophisticated technology, an instrument and sensor network and long term data set, the Cadet Hand Library, teaching classrooms and lecture hall, wetlabs, greenhouses, Dive Training facility, seawater system and vessel fleet. BML is administered by UC Davis, one of the nation's top public universities and a leader in both the marine and life sciences.


I was fascinated to learn that their location on Bodega Head is unique because it includes a rich mix of eight protected coastal habitats to study: rocky intertidal areas, protected and exposed sandy beaches, extensive lagoon mudflats and sandflats, and tidal saltmarsh, sand dunes, coastal bluffs, coastal prairie/coastal scrub and freshwater wetlands. Plus, plant communities, soils and microclimates vary sharply over relatively small distances due to geological factors associated with the Pacific Ocean and the San Andreas Fault Zone.

The Marine Lab is located in the Bodega State Marine Reserve, a fully protected no-take reserve extending 1000 feet offshore, managed by the California Department of Fish and Game and BML. The Bodega State Marine Reserve is contiguous with NOAA's Gulf of the Farallones National Marine Sanctuary, providing additional research sites and opportunities.

But back to the tours, if you go over expecting something like the Monterey Bay Aquarium, you'll be disappointed. The Bodega Marine Lab is primarily an education and research facility with a few displays for the public.


They had a nice "tidal mesocosm" out front with various marine life including sea stars, bat stars, anemones, and my favorites, purple sea urchins. I asked our docent why I haven't been able to find any sea urchins in the tidepools along the Bodega Bay coast for several years, I used to see them all the time. He said he had no idea and in fact, had never visited a tidepool in the Bodega Bay area. Oh well...



I enjoyed the beautiful displays in their expansive lobby and actually learned more there than on the tour itself.








They also had two large tanks displaying local fish.




I would have liked to hear more about some of their current local studies. We were shown a lobster study in progress, although there aren't any lobsters in the Bodega Bay area at all.


We were also shown these tanks, where they're conducting an algae study.


You can read more about the Bodega Marine Lab tours here. For a more complete Bodega Bay marine life experience, I'd suggest visiting some real tidepools during low tide before or after your tour. You can see some of our tidepool photos here. Also, during the months of January-May, you can go whale watching up on Bodega Head, with knowledgeable volunteer docents answering questions and providing a wealth of educational materials. You can read more about whale watching here. Although as a side note, some people spotted whales offshore just this past week!

Have fun!

Low Tides in Bodega Bay


We've had some unusually low tides recently, revealing an abundance of tide pool life. Over Memorial Day weekend we had a houseful of family and friends and everyone bravely woke up bright and early to catch the 5:47 a.m. low tide of -1.6. Clearly some of the creatures we found rarely see the light of day.





They're hard to see, but we found a row of crabs just beneath the sand around this rock.




I had to remind the kids not to disturb the marine life. It's okay to look but don't touch. Not that I'd want to, some of these creatures are pretty freaky-looking...



Come and see for yourself! We're expecting super-low tides again this month, -1.8 on June 23 at 6:21 a.m. and June 24 at 7:08 a.m. I heard someone say there's also an increased chance of earthquakes around that time, but I haven't found anything to substantiate it. Brace yourself just in case.
