Algae - Trentepohlia aurea v. polycarpa. This microscopic alga thrives on ocean salt spray and forms dense colonies on Monterey Cypress (Cupressus macrocarpa) along the Pacific coast. Despite its color, the species is actually a green alga. The chlorophyll pigment is masked by high levels of beta-carotene, the orange pigment found in carrots. Fitzgerald Marine Reserve.

"The best way to predict our future is to invent it."
(Alan Kay 1971)
Open Sailing aims to design and invent future lifestyles to overcome any possible natural and manmade disasters stimulating people’s ingenuity and sense of solidarity. Might it be global warming or energy conflicts, we are living in a time where we are sniffing the ‘Apocalypse’, finally realising our human part of responsibility as the earth is crumbling. 2012 is a year when a collection of apocalyptic events are rumored to happen. We are taking 2012 as an ideal dystopic symbol we design for. 2012 is tomorrow, we must design quickly using these constraints and invent bootstrapping DIY technologies.
Open Sailing method is to convert apocalyptic threats into design constraints. From our compiled set of threat maps, we found that oceans are the safest locations. Ocean survival architecture became our new starting point, but we need to go further than surviving : how can we live together in this new fluid configuration and remain a hyper-connected intelligent social being? We are trying to make a truly “open architecture” : pre-broken, under-defined, reconfigurable, moveable, pluggable, organic, fluid. Can we reach a harmonious dynamic state of interdependence with each other and the earth? Is this the next step of civilization progress? Will we dissociate our concept of progress with infrastructure and metropolis?
NEXT STEPS IN 2009
Finding motivated knowledgeable collaborators and funders (february).
Prototyping technology equipment for ocean living, UK (march ~ april).
Testing the Open Sailing in the Atlantic ocean, Morocco (may).
Public presentation of Open Sailing researches (june)

This is a picture of a pied billed grebe working on her nest on the pond along the 6th fairway on The Villages Gold course. These pictures were taken just after 7 p. m. She was very busy, moving vegetation around and collecting new algae and sticks to add to the nest. She left the nest for about four minutes and swam around, perhaps feeding. She went about 30 feet away from the nest on the surface and then swam back to the nest underwater.
Have a new set of beach photos so you know what you'll see these days :)

Wet & Forget was applied to many surfaces in Mackinac Island including, wood roofs, stones, siding, and the oldest stone wall in Michigan. Most of these surfaces were covered with moss, mold, algae, and lichen.
Algae are a large and diverse group of simple, typically autotrophic organisms, ranging from unicellular to multicellular forms, such as the giant kelps that grow to 215 feet in length. The US Algal Collection is represented by almost 300,000 accessioned and inventoried herbarium specimens. The largest and most complex marine forms are called seaweeds. They are photosynthetic, like plants, and "simple" because they lack the many distinct organs found in land plants.
Algae are found in the fossil record dating back to approximately 3 billion years in the Precambrian. They exhibit a wide range of reproductive strategies, from simple, asexual cell division to complex forms of sexual reproduction.

The lake in the Sepulveda basin (Not Balboa; the other one. Does it have a name?) drains at the south, and the algae floating on swirling water made some interesting patterns. I took several pictures, and I'm still deciding if I like them.
NOTE: this picture is currently being linked from a site named "STL Beds" that has included this picture in an article about changing the water in a waterbed. I have no affiliation with STL Beds, and no opinion about the accuracy of the article or the merits of STL Beds.
Hot springs are sites where groundwater emerges at the surface and the water is hotter than the human body. In many cases, hot spring water is boiling hot, or close to it. At Yellowstone in Wyoming, most hot spring water precipitates opal (hydrous silica, SiO2·nH2O), resulting in buildups of geyserite, a chemical sedimentary rock. Some Yellowstone hot springs precipitate calcium carbonate (CaCO3). Seen here is a hot spring in Hot Springs National Park in Arkansas. The algae-covered rocky buildup is calcium carbonate. Chemical sedimentary rocks of calcareous composition formed by hot spring water include "calcareous tufa" and "travertine". I'm not entirely convinced there is a difference - the terms are often used interchangeably. My understanding is that "calcareous tufa" (a horrible term, by the way) is a porous, friable precursor to travertine. Travertine also forms in caves (calcareous speleothem) and at some cold springs.
Supposedly, the original tufa/travertine deposits here have long since been destroyed and the layout of hot springs and the drainage patterns are all artificial. The modification took place to accommodate the need to pipe hot water to nearby bathhouses in early days. Tufa/travertine deposits now at the site are probably all secondary.
-------------------------------------
From park signage:
Thermal Cascade was designed to recreate the natural scene of hot spring water cascading down tufa cliffs. In cool weather the vapor is reminiscent of the clouds that once billowed from open springs along the lower slope.

Tufa Terraces
Before the bathhouse era, this lower side of the mountain was covered with massive terraces of tufa (travertine). Tufa is mostly calcium carbonate, which precipitates out as the spring water cools. In 1834 a British geologist observed that “The travertine . . . sometimes presents abrupt vertical faces of from 15 to 25 feet high.” Tufa formations are still visible along this trail.
After a short ascent past tufa outcroppings and the Thermal Cascade, Tufa Terrace Trail crosses the Grand Promenade. From there you can reach the Peak Trail and continue up Hot Springs Mountain.

THIS VALLEY, LONG KNOWN BY THE INDIANS AS “TAH-NE-CO,” “THE PLACE OF THE HOT WATERS,” AND ACCORDING TO TRADITION REGARDED BY THE DIFFERENT TRIBES AS NEUTRAL GROUND, WAS FIRST VISITED BY WHITE MEN ON SEPTEMBER 16, 1541, WHEN HERNANDO DE SOTO AND HIS MEN CAMPED IN THIS VICINITY AND WERE LED HERE BY THE INDIANS. ACCORDING TO RECORDS OF RODERIGO RONJEL, SECRETARY TO DE SOTO, AND THE “GENTLEMAN OF ELVAS,” WHO WAS ALSO A MEMBER OF THE COMPANY, THEY BATHED IN THE HOT WATERS AND DEPARTED OCTOBER 5, 1541.

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.

Probably not it's real name. Not really even a lake. It had a lot of little streamy algae in it though.
Clatto Reservoir is split into two parts, with the smaller part being covered in algae. Despite there being a bit of a breeze blowing on the evening I was here, this part of the reservoir remains sheltered and possibly explains why there's so much algae growth here. Another thing worth mentioning is that clump of trees isn't an island, it is in-fact a peninsular.
Just to the right of this photo is a metal walkway that goes partially out into the water. When I first started coming here, you could freely walk on it and get a good view of the water but in recent years, some prick has put a caged area over the walkway to stop people getting on. It's easily bypassed and I go round it every time as a point of principle.
