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.

Algae Bloom off the Coast of Estonia on July 16th, 2002. Cyanobacteria can be found in almost every terrestrial and aquatic habitat. With the appropriate conditions these can bloom and be seen from space as blue-green patches that swirl following surface currents. Lines cutting across the image are the traces of ships. Factors that lead to these blooms include low winds, increasing temperatures, and nutrients such as phosphorus (often byproducts of fertilizer runoff along the rivers). These blooms can be toxic and are often monitored from air and space.
"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.

Drying red algae carpets the beach, a common occurrence in the bay, area touch of sunshine and calm weather is all that's needed.
Dunnet Bay, Caithness, Scotland.
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.

Lithophyllum carpophylli - really needs a common name. This grows on other brown macro algae and unlike most coralline algae it creates beautiful 3d structures.
Norris Geyser Basin in Yellowstone National Park is home to many interesting microorganisms which give the pools their colour. Prominant here is the Metallosphaera sp forming the orange colour in the spring and Cyanidioschyzon sp in the lower half of the image. The Metallosphaera is an Archaea and as such metabolizes metalic sulfur compounds. The Cyanidioschyzon is a red algae. Both are adapted to very high temperature and acidic environments.

The colors from the algae change with seasonal changes in temperature.

This is just algae on the shore. They are not harmful. It's save to swim here.
I have just put more contrast to the image, nothing else.
I didn't quite capture the beauty in these little algae disks forming on the side of my empty aquarium... but I promise it was there :)
A new PNNL study shows that 17 percent of the United States’ imported oil for transportation could be replaced by biofuel made from algae grown in outdoor raceway ponds located in the Gulf Coast, the Southeastern Seaboard, and the Great Lakes. This June 2010 satellite photo shows raceway ponds in southern California.
