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.

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

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.

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.

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 :)

From 2009. Under a moderately-high magnification of 2500X, this digitally-colorized scanning electron micrograph (SEM) of an untreated water specimen extracted from a wild stream mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular view, a microorganism is featured, the exterior of which is covered by numerous projections imparting an appearance of a sea urchin. This microscopic “pin cushion” was teathered to its surroundings by a biofilm within which many bacteria, and amoeboid protozoa could be seen enmeshed as well. See PHIL 11781 for a greater magnification of this organism’s exterior.
Though many organisms found in untreated waters are harmless, there are many that are pathogenic to both humans and animals, including Giardia spp., free-living amebae, and E. coli just to name a few. During power outages, the functionality of treated water systems can be negatively affected, thereby, violating the patency of these closed systems. In these instances, advisories may be posted, encouraging inhabitants of these regions to boil their water tap water in order to kill off any pathogenic organisms that may have entered the system due to an intrasystemic drop in positive pressure.
Not only do water treatment plants remove such pathogenic organisms, but chemical that can be injurious to humans and animals are filtered from the water making it potable. Again, during power outages, or in the case of broken pipes, chemicals can contaminate tap water rendering it unsuitable to drink as well.

This is a covered walkway that connects the bridge from the previous two photos with the main entrance of Bielefeld University, Germany. It's quite foggy so a lot of light is scattered before falling through the glass roofing from all angles. They have kind of an algae problem with this roof, also speaking to the quite humid climate Bielefeld is renowned for. Let's just hope the lunatics in the US Congress withstand reason long enough for things to just get a tiny bit more arid around here.
Pentax PC35AF, Kentmere 100 @ 100
Los Angeles County, California, March 2022
Found while exploring some new curvy roads. Negative is a dusty, scratchy mess, but I love this sign. First roll with my newly-acquired PC35AF. Had one as a kid, kept it with me all through college, and this one is once again my constant companion. What a delightful little camera. Never did find any algae, though.

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.
