Other components of siliceous oozes near continental margins may include terrestrially derived silica particles and sponge spicules.
WitrynaThe water is more saline with depth, and higher salinity means greater acidity. b. The lack of marine life in deep water means that a smaller amount of organic acids is released into the water by biological activity. c. Deeper, colder ocean water contains more dissolved carbon dioxide, which causes the pH to be lower.
Silicate, or silicic acid (H4SiO4), is an important nutrient in the ocean. Unlike the other major nutrients such as phosphate, nitrate, or ammonium, which are needed by almost all marine plankton, silicate is an essential chemical requirement for very specific biota, including diatoms, radiolaria, silicoflagellates, and siliceous sponges.
