Today’s blog comes from one of our Education Specialists, Becca! When she’s not in the office or a classroom, you’ll most likely find her at the beach!

Sometimes we chose to live by the ocean, but lack understanding of it. When we understand what we are living next to, we can help take care of it. This blog is for beach goers who admire the ocean but do not yet completely understand it.
What is all of this stuff lying out on the sand? What are those holes I see in the sand when the wave returns to the ocean? What is that smell on the beach?
What is algae? Algae is a living organism that photosynthesizes like a plant. The difference between the two is that plants produce flowers and algae does not. For those of you that have not yet snorkeled or dived in a kelp forest, it is something worth mentioning. Kelp is one of the most important producers off the coast of California. What is it producing? Oxygen for all air breathers, homes for animals, and food for animals like urchins. It is also one of the many species of algae you will find washed up along the beach.
Sand also covers our beaches and thanks to this resource, we have interesting animals living in the sand called Pacific Mole Crabs. Pacific Mole Crabs are filter feeders; they eat by waving around their secondary antennae in the water. They don’t have claws, so don’t worry about those when you hold them! These creatures burrow through the sand and act as an indication of the health of the ecosystem. Their presence reassures us that we have healthy beaches. When you next see bubbles in the sand after the wave returns the ocean, dig down to find some Pacific Mole Crabs.
How about the smell of the sea breeze? The ocean’s smell is a combination of a few elements. If it were a recipe, it would look a little something like this:
- Bromophenols: Comes from fish, oysters, shrimp, crabs, and oysters as a result of their diet which includes algae, worms, etc.
- Dimethyl sulfide (DMS): The clammy or sulfur smell comes from bacteria that eat phytoplankton.
- Dictyopterenes: Pheromones of algae, as most would guess, smells like dried seaweed.
Next time you walk down to the beach, feel free to explore! The more you about the beach and its ecosystems, you’re bound to discover whole different world!
