If you ever fly over San Francisco Bay, be sure to fellow out of the screen to get a glance of one of the most amazingly shaded scenery - the salt water loss ponds managed by Cargill, Inc.
Salt water loss ponds are superficial synthetic ponds designed to generate salt from sea water or other brines. The sea water or brine is fed into large ponds and water is attracted out through natural water loss which allows the salt to be therefore gathered. During the five years it takes for the bay water to older into salt brine, it is shifted from one water loss lake to another. In one more levels, when the brine is completely over loaded, it is injected to the crystalizer where a bed of salt 5 to 8 inches wide wide is ready for collect.
Salt ponds range from red natural to deeply green – shaded normally by the harmful bacteria that flourish as salinity levels increase. Large indicates the salinity of the ponds and the type of harmful bacteria that is reproduction on it. Three harmful bacteria in particular, Synechococcus, Halobacteria, and Dunaliella, impact the shade of salt ponds.
In the low-salinity ponds, both shade and microbiology go with the red natural ocean of San Francisco Bay. As the brines focus, several plankton, such as Dunaliella, provide a natural throw to the brines. With improving salinity, Dunaliella out-competes other harmful bacteria and colours differ from light natural to shiny chartreuse. About almost through the lake system, the improved salinity encourages huge people of small brine shrimp, which explain the brine and color it. The saltiest brine, or pickle, seems to be deeply red, because Halobacteria take over and the hypersaline brine activates a red color to form in the Dunaliella’s protoplasm.
The scheme of salt lake colours shows an uncommon micro-biota. Yet it is more than just a fascination of characteristics. The plankton and other harmful bacteria make the base for a wealthy environment, assisting more than a thousand shorebirds, waterfowl and other animals. At the same time, these small animals control water excellent -- which encourages growth of a better excellent salt.
