A rare and unusual specimen of algae preserved in clear chalcedony. Originally it would have been growing in silica-rich run-off from geothermal hot springs. Kaueranga Valley, Thames
A massive late-stage algal bloom on Upper Klamath Lake. The turquoise color is algal pigments being released during cell death. Photo provided by OSU College of Science.
Some of the earliest Eukaryotic organisms ever uncovered, though it is still far younger in age than fossil discoveries of Archeal cyanobacteria.

On July 19, 2010, the Huron River in Ann Arbor, Michigan had a pollution spill. The case is unsolved but closed. Booms were setup, the pollution flowed for hours and I witnessed it. Yet no one was ever charged. Someone was able to spill something and get away with it.
20 Days after the spill, I went for a walk around Gallup Park. Here are the photos that I took that day.
After the booms failed the pollutants presumably went downstream and dispersed. The boom failure was due to a rain event, but the initial spill was not. There is a considerable amount of press related to phosphors from fertilizers that focuses on the average citizen, and Gallup Park had an algae bloom that can be caused by pollution from phosphors. Remember, the AAFD report stated an 88% confidence of phosphoric acid in the spill (a DPS report states that the AAFD report with the acid reference may be inaccurate). Also, some reports stated that petroleum was mixed in as well. I know that I could smell something, so the reports that state that it was 'non-odorous' are not complete. I'm not saying that this spill caused all of the algae in Gallup, but unless Ann Arbor tells me that petroleum and acid is allowed to be dumped legally, then this spill could not have helped the environment, and as there were no accident or permit reports, I presume it must have been illegal?
According to the City of Ann Arbor, "A Resident's Guide to Clean Water", Spring 2010 edition:
www.a2gov.org/government/publicservices/systems_planning/...
"Dumping waste into storm drains, ditches, or waterways contaminates drinking water supplies, recreational areas, and wildlife habitat. Plus, it is illegal"
"In Ann Arbor, an ordinance prohibits the use of fertilizers containing phosphorus unless a need is demonstrated through a soil test"
According to the HRWC
"nuisance algae blooms that can result from excess phosphorus entering our freshwaters"

Large Riff Raff rocks at Lexington,Michigan Harbor. It was a rainy Summer. This boulder got some lake waves to splash, thus causing growth of algae.
I scooped up some algae from a neighbors exposed stream. It looks
like a marine blue/green variety. I am going to try and send it off
for testing. I am curious about oil content and the species type. If
our local algae has 30% or more lipids it would be a good choice for
diesel oil alternatives. Otherwise I'll just buy some B. Braunii or
D. Salina strains which have been used more than other algae strains
for fuel production research.
Unidentified species of (red?) algae. Similar to Gracilaria/Gracilariopsis (?)

This algae or maybe cyanobacteria was growing in a stream in northern Minnesota all winter. The mild temperatures this past winter never let the stream freeze over.
