Algae is harvested from stones in the river, then beaten, dried and eaten. It's said to be very high in protein.
Just across from a PG&E power plant and the Naval Shipyard Superfund site, it's hard to keep nature down.
Filamentous algae and bubbles seen along the shore of San Francisco Bay at the Berkeley Meadow portion of McLaughlin Eastshore State Park.
This algae is beginning to form floating green mats in this part of the bay. Perhaps the bubbles are made of oxygen generated by algae photosynthesis? Later, when the algae mats die, their decay consumes oxygen, but at this stage the algae is probably generating lots of it.
This photo looks like it was taken underwater, but actually I was standing at the shore looking at the edges of the mats. A gentle wind was slowly blowing the mats around so they were constantly changing, almost like clouds. The sky was clear and sunny, making the bubbles shine brightly.
Taken with a 100-400mm zoom even though I was only a few feet away from the algae, basically a "telemacro" mode. The depth of field is rather shallow, but the blurring around the sides enhances the feel of this image, rather than detracting from it. The field of view here is just a few inches.
I am not sure of the exact species of this algae. But its mats sure looks like the Rhizoclonium riparium that blanketed Richardson Bay across the bay in Marin four years ago, in June 2020.
Another view of the calm lagoon separated from the rough surf by a wall of algae. Note the ducks taking it easy, not having to deal with the waves.
I am mesmorized by the textures.
Mori Junuchi's madonna/virgin sculpture at the armory was constructed of a type of sea algae.
as you can imagine- I want it.:)

Various combinations of algal species were grown in 80 cattle tanks for a biofuels experiment. Photo by Daryl Marshke/Michigan Photography.
