Lake Shala, in the East African Rift Valley. A soda lake or alkaline lake is a lake on the strongly alkaline side of neutrality, typically with a pH value between 9 and 12. They are characterized by high concentrations of carbonate salts, typically sodium carbonate (and related salt complexes), giving rise to their alkalinity.
Measurement of diel changes in dissolved gases within the lake, also known as the "free-water" method, has quickly become the most common method of estimating lake metabolism since the wide adoption of autonomous sensors used to measure dissolved oxygen and carbon dioxide in water.
Oxygen is a by-product of photosynthesis, so systems with a high abundance of aquatic algae and plants may also have high concentrations of oxygen during the day. These levels can decrease significantly during the night when primary producers switch to respiration.
Other characteristics include a pH of 5.2, an 84-m-thick brine layer, and high levels of hydrogen sulfide. [8] [32] The Atlantis II Deep is among the largest Red Sea brine pools and has high temperatures (~68 °C), a pH of 5.3, and high metal content.
Features that are part of the water circulation system can extend treatment capacity needs for sizing calculations and can include: artificial streams and waterfalls, in-pool fountains, integrated hot tubs and spas, water slides and sluices, artificial "pebble beaches", submerged seating as bench-ledges or as "stools" at in-pool bars, plunge ...
Water is really good for you, no one is arguing that. But are certain waters better for you than others? Depends on who you ask. While plenty of people are content to drink plain old H2O, there ...
Aquatic photosynthesis is the occurrence of photosynthesis in the aquatic environment, which includes the freshwater environment and the marine (saltwater) environment. . Organisms that perform photosynthesis in the aquatic environment include but are not limited to plants, algae, cyanobacteria, [1] coral, [2] phytoplankton (also known as micro
Bacteria need large amounts of oxygen to decompose this material, thus reducing the oxygen concentration of the water. This is especially pronounced in stratified lakes, when the thermocline prevents oxygen-rich water from the surface to mix with lower levels. Low or anoxic conditions preclude the existence of many taxa that are not ...
