Description:
A gator kicks up fecal ooze from the bottom of the lake. A seasonal bloom of green algae typically occurs in the winter months, December to March. Generally the green algae bloom during the winter when there isn’t so much direct sunlight. Half of the lake bottom should be covered in a green mat this time of year. When it is brown, it is because it has been killed by the unusual cold. (Fecal pellets from green algae disintegrate rapidly in contrast to their blue-green brethren.)
The ooze has been accumulating for about 3000 years (since the sinkhole suddenly subsided a bit too much for the swamp grass). It sits on top of over 20’ of saw grass peat of Pleistocene and Holocene age.
The marginal vegetation and mats that surround the lake effectively keep out non-organic sediments. The water is alkaline. In fact, it is similar to the alkaline bogs of Michigan and Wisconsin, only it is more alkaline.
Strangely, there are no phytoplankton or zooplankton in the water. It could be because of the intensity of sunlight or extremely cruel and efficient micro-predators, or both. The lack of plankton is considered a significant aberration.
There is also an absence of bacteria. Apparently the water contains something of a bacteria inhibiter. The shallowness of the lake and intensity of sunlight might also be a factor. In any case, there are no bacteria to attack the blue-green algae sewage.
Geologists like to study this kind of thing. It reminds them of the origin of western oil sands (like the Green River Formation of Eocene age). These are lacustrine in origin (from Gosiute and Uinta paleo-lakes) and are found in Utah, Colorado and Wyoming. Since the oil represents captured energy from an ancient sun, the sediments are sometimes referred to as “energy sinks.”
Geological consensus (today) is that blue-green algae corpses are a necessary prerequisite for lacustrine oil sand formation. That means microbial poop might be future fuel for SeaReys.
