8x10 pinhole very close to water (algae) level, making the algae look much more expansive than it was. That log in the water was only about 25 feet away while the opposite shore was easily several hundred feet away. The foreground is very stretched out.
Efke IR820 with 25a medium red filter and about a 2.5 minute exposure. Developed in Rodinal 1+50 for 10 minutes (drum).
At Verkeerder Kill Falls, noticed this algal "curtain": a continuous sheet of water with long strings of algae hanging down. A curiosity.

One cell of the colonial diatom Melosira shown with the filamentous alga. Photomicrograph taken with a Coolpix 885 at 3x zoom, using an Olympus microscope equipped with Hoffman Modulation Contrast optics, oil immersion at 1,000x magnification.
Cladaphora are freshwater algae that grow on submerged rocks, logs and other hard surfaces. Research has linked cladaphora blooms to high phosphorus levels resulting from fertilizing lawns, poorly maintained septic systems, inadequate sewage treatment, agricultural runoff, and detergents containing phosphorus.
PondZilla is very effective, when used as an adjunct to an algaecide or herbacide*, at controlling filmantous bacteria in ponds such as cladophora.
Aquafix created PondZilla utilizing the latest in enzyme technology to degrade 30-60% of pond muck at 1/10th the cost of physical cleaning*. Pondzilla helps degrade muck and sludge in lakes and ponds by activating the muck layer and stimulating bacterial activity. It contains surface-activating agents, which liberate pond muck and allow the active ingredients to speed up nature’s natural decomposition cycle. It works particularly well in ponds with filamentous problems.
*While bacterial products cannot kill aquatic plant growth, when used with algaecides or herbicides, they can help restore natural balance.

This 200X magnification of the algae from our hot spring drain was
taken with the Intel QX5 microscope. I removed the bottom plate of
the microscope and added a light that is about fifty times brighter
to obtain this photo. More interesting photos to come.
see the winch line.. that's how they pull up the nets, some other are filling further down the cliff.. hard work in the scorching desert sun.. This algae is used in many products now. ( beauty prods I think ) --
Icebergs are not lifeless. They are homes to billions of tiny and not so tiny creatures, from iron bacteria to snow algae and seals.
took this one with my cellphone cam, i don't remember too well but i think this is an algae, most likely chlorophyceae with blue dye.
Si mal no recuerdo es un alga de las chlorophyceae, teñida con azul de metileno para ver cloroplastos. La tome con mi cel.

Wandering during the last few days in a thermally active area behind the Sierra Nevada, I happened to find a beautiful hot spring in northern Mono county, California. The unbearably hot water (around 50°C, or 120°F) deposited beautiful albeit minuscule terraces of travertine upon cooling, and flowed downhill creating ponds and rivulets. In some of these, the temperature seemed to be right enough for algal blooming, like in this image. I loved the tenacity of life, algae living in hot water while the snow was around me, and as I always side, I love green, particularly this hue. The scale on this image is essentially 1:1. One can see the dry grass on the edge of the rivulet and the full color of the algae below the water. Flow direction is right to left. The algae is actually anchored to a thin veil of calcium carbonate (travertine) that encrusts the stream bottom.

Dr. Isaac Berzin has stayed true to his algal calling, but is improving the economics of the process by also harvesting valuable biomolecules, not just bulk fuel.
