During our naturalist-led kayaking trips in Elkhorn Slough, we discuss what lives both above and below this rich ecological wetland area. The eelgrass beds are expanding due to an interplay among three Slough species.

A fascinating relationship has developed among the Taylor sea hare, their crab predator and the charismatic coastal marine mammal, the southern sea otter, Enhydra lutris nereis. During the early 1980’s, Elkhorn Slough and its associated eelgrass beds experienced a recruitment of the southern sea otter. As the otter’s range expanded into the slough, the population of Phyllaplisai taylori expanded correspondingly since otters started keeping a check on several crab species, which prey on the slug.

Not only did Phyllaplisai taylori expand in numbers but also they tended to live longer and grow larger with fewer pressures from crab predation.560220_871548582889436_8191899317797331968_n-1

As the slugs flourished in the Elkhorn Slough, the eelgrass beds became notably healthier. The slugs grazed upon many of the encrusting algae forms that would otherwise compete with eelgrass for sunlight. Acting as a nursery arena for a variety of marine fauna, healthy beds of Zostera marina is a highly desirable trend.

During certain times of the year, we observe a high density of certain sea jellies such as the Red Eye Sea Jelly caught on video here.

Our school field trips to the protective water of Pillar Point harbor sometimes have some real surprises. During the fall of 2016, Humpback whales were consistently seen lunge feeding near shore where students could observe safety from the jetties. An amazing teaching opportunity!OLYMPUS DIGITAL CAMERA

Launching from Pillar Point Harbor, we’ll have a leisurely paddle through the protected and scenic harbor. Cormorants, pelicans, terns and harbor seals join us for our naturalist-led field trip. Across the harbor we can beachcomb, explore tidepools and have a shore lunch before paddling back.

A very popular activity with students is pulling a large seine net to examine our catch and continue our discussion of animal adaptations. Teachers, please feel free to call us to discuss curriculum ideas in greater detail.

The cost of your field trip is $48 per person with a complimentary trip for one teacher chaperone. $50 per person weekends.

Hope you can join us!

Our Blue Water adventures are planned according to the tides, not a bad way to live at all! The recent extreme high and low tides, rain or shine have offered some true adventures along our California Coast.

Our week of King tides promoted by the alignment of the earth moon and sun offers so many opporunties to see our coast in a new perspective…get out there and look around or join us at http://www.bliewaterventures.org.

Our tours are all naturalist-led and highly informative.

Its been a week of EXTREME fun and exploration with my Clemson graduate school friends, a 33 year reunion! At daybreak, we headed to Davenport Landing for extreme tidepooling. From kayaking among the giants (humpback whales) to intertidal discoveries its been an amazing week!
We found only one healthy ochre sea star (Pisaster orchraceus) spared from the fatal sea star wasting syndrome. Thought to be a virus effecting sea stars from Alaska to Baja, SSWS has researchers along our coast working hard for more answers.

Join the naturalist of Blue Water Ventures as we explore and discuss the tidepools of California’s Central Coast. Discover how tides work, how beaches form and about the survival strategies of intertidal inhabitants. Activities may include collecting data from designated study sites, line transects and a beach discovery walk. As professional educators, we know how to design educational and fun activities to the appropriate age level.
