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.

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 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

The colors from the algae change with seasonal changes in temperature.
Taken on a Perfect Light photo workshop.
M.G. seeing if she can grab some of the (seasonal) infestation of Hair Algae that chokes some of our coral.
Lithophyllum carpophylli - really needs a common name. This grows on other brown macro algae and unlike most coralline algae it creates beautiful 3d structures.
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.
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.

Esbelta y afilada, la diatomea Navicula corta el agua a ritmo de piragua ▷. En su estuche de cuarzo puro apenas se marcan unas delicadas costillas transversales y bajo ella empiezan a amarillear los pigmentos, aparecen ya los colores del otoño. Navega ligera, como una canoa, hacia adelante y hacia atrás recorriendo pequeños continentes en este su viaje por una gota de agua.
Al igual que todas las diatomeas, Navicula puede desplazarse en el agua a reacción, liberando un líquido a presión por unos poros casi invisibles situados en el extremo de su proa y de su popa. Lo hace ésta y lo hacen todas sus hermanas, que suman cerca de 10000 especies diferentes, una gran familia para construir una flota.
El género Navicula es uno de los más extensos dentro de las algas diatomeas, vive tanto en aguas dulces como saladas y son características de él los cloroplastos cilíndricos situados en los costados de la nave, a babor y a estribor. Pueden vivir en aguas limpias pero también en las ligeramente contaminadas.
La fotografía procede de una muestra de agua recolectada hace unos días en el Pozo de Tremeo una pequeña laguna natural situada en Rumoroso (Cantabria), el amigo Fernando también me llevó allí, después de visitar el pozón de La Dolores. La toma se ha realizado a 400 aumentos empleando la técnica de contraste de interferencia.

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.

Deliberate deposit of calcareous algae at Ahu Heki'i 2, Rapa Nui. Calcareous algae forms under water. On Rapa Nui, it is frequently found in terrestrial contexts, which it could not have reached naturally. Since it has no known functional uses, it is assumed to have been imported into these locations deliberately for decorative and/or ritual reasons. Concentrations are often found at ahu, such as Ahu Heki'i 2 shown here.
