In he late spring, the stream has dried up and all that is left are algae filled pools. At first when we started the hike, it looked completely dry. That would have been disappointing because the description in Afoot and Afield indicated that there would be a pool with a waterfall along the hike.

Pebbles of various sizes line the bottom of thie shallow and beautiful section of the Bow River, with gently rippled water and golden morning sunlight creating a lovely abstract effect as they flowed over the rocks.
I thought this shot was particularly cool as a patch of algae had built up around one of the larger pebbles, providing wonderful contrast of both color and texture to the surrounding rocks and water!
Algae, possibly gloeocapsa, at 600x. Found in a sample from an artificial pond in the park near 1st Street and Chesterfield in North Vancouver, BC, Canada.
Toward Dunwich, there were several small pools that had formed a short distance from the beach.
There is lots of algae in these pools & the presence of it, makes for some very vivid colours.
I am growing algae. What I can't figure out is the perfectly straight line of demarkation between "algae" and "no algae" on the back of the tank. The algae just stops, six inches from the top. Not a gradual cessation, either. A perfectly straight and sudden boundary. I can't think of any explanation. If you have one, I'd love to hear it!

Volvox is a spherical colony of algae, that moves "rolling" through the water of some ponds and ditches. Every onecel alga has a long whip wire. They are not very common but sometimes wide spread. Inside the globe are new colonies formed. After a while the big one burst open en releases the "newborns"
Volvox is een kolonie algjes die samen een bol vormen en zich met zweepdraadjes rollend door het water bewegen van sommige sloten en plassen. Verrukkelijk om te bekijken.
In de bol worden nieuwe kolonies gevormd die vrijkomen als de "ouder" openbarst.

"Wheel" pattern doily for the upcoming Emmett Christian gallery "algae slime" installation at SUNY Fredonia in conjunction with the exhibition "Gone Viral: Medical Science and Contemporary Textile Art" opening March 8th in the Marion Art Gallery. If you would like to contribute green/blue doilies for this exhibition, please contact me for details. Due date for submissions is March 1.

This project inspired by The Hyperbolic Crochet Coral Reef Project:
The substance on the trunks and branches of these trees is called "Trentepohlia". It is a genus of filamentous green chlorophyte algae that lives on tree trunks and wet logs. The strong brownish-orange color of the filaments, which mask the green of the chlorophyll, is caused by the presence of large quantities of carotenoid pigments. I found trees covered with this growth on the top of a high bluff overlooking the Pacific Ocean near Half Moon Bay in northern California.

This red algae comes back in our bird-bath time after time. I have tried all sorts of ways over the years to stop it reappearing. None have worked
Jerilyn Timlin serves as a principal investigator for the Algal Predator and Pathogen Signature Verification project. The project looks at exploring and exploiting the various detailed optical signatures that arise when the algae cultivation pond surface is monitored using Sandia’s optical spectroradiometric techniques. These techniques can differentiate algae growth and state of health and provide an early warning of the active presence of predators and pathogens in outdoor algal ponds.
In 2009, Jerilyn was presented by the National Institutes of Health (NIH) with a New Innovator Award to develop state-of-the-art imaging technology that can measure protein complex formation and protein networks.
