Studies on microbial processes in wetlands should be submitted to Terrestrial Microbiology. These currents transport large amounts of sand along coasts, forming spits, barrier islands and tombolos. One example, xenophyophores, have been found in the deepest ocean trench, 6.6 miles (10,541 meters) below the surface. 1975 Jan;47(1):9-19. Aquatic Microbiology is devoted to advancing the study of microbes in aqueous environments, with a focus on freshwater, estuarine and oceanic ecosystems. The importance of environmental microbiology continues to grow as new microorganisms continue to emerge in different environmental sources. They are the backbone of all ecosystems, but even more so in the zones where light cannot approach and therefore photosynthesis cannot be the basic means to collect energy. In nature, microorganisms contribute to biogeochemical cycling, as well as turnover of material in soil and aquatic habitats. This is problematic for some organisms with pervious skins or with gill membranes, whose cell membranes may burst if excess water is not excreted. Plankton are primarily divided into broad functional (or trophic level) groups: Phytoplankton, Zooplankton, and Bacterioplankton. In such zones, chemosynthetic microbes provide energy and carbon to the other organisms. Ocean oxygen depletion and resultant methane production (caused by the excess production of remineralising at depth) is one potential drawback. The first type of organism to take advantage of this deep-sea energy source is bacteria. ... play numerous roles of importance that are often neglected or overlooked in … Marine habitats include coastal zones, intertidal zones, sandy shores, rocky shores, mudflats, swamps and salt marshes, estuaries, kelp forests, seagrasses, and coral reefs. Types of cold seeps can be distinguished according to the depth, as shallow cold seeps and deep cold seeps. The reefs are composed of mounds called “bioherms” that are up to 21 m high, and sheets called “biostromes” that are 2-10 m thick, and may be many km wide. For example, the Halomonas species Halomonas salaria requires a pressure of 1000 atm (100 MPa) and a temperature of three degrees Celsius. That is, plankton are defined by their ecological niche rather than phylogenetic or taxonomic classification.

Microbes also help in the treatment of wastewater by promoting the decay of all the garbage from the water resources. Sewage effluents are also a major allochthonous source of the mesophilic aeromonads in the aquatic environment. Pelagic habitats are intrinsically shifting and ephemeral, depending on what ocean currents are doing. Marine life partially depends on the saltwater that is in the sea (“marine” comes from the Latin “mare,” meaning sea or ocean). Environmental microbiology is the study of the various microorganisms present in the environment, including soil, water, and air. They provide a crucial source of food to many large aquatic organisms, such as fish and whales. Microbial life plays a primary role in regulating biogeochemical systems in virtually all of our planet ‘s environments, including some of the most extreme, from frozen environments and acidic lakes, to hydrothermal vents at the bottom of deepest oceans, and some of the most familiar, such as the human small intestine. Aquatic microbiological studies are diverse and inherently interdisciplinary. They occupy a key position in the food chain by providing rich nourishment for the next higher level of aquatic life. The field is concerned with the structure, function, and classification of such organisms and with ways of both exploiting and controlling their activities. Plankton ecosystems also play a crucial role in the biogeochemical cycles of many important chemical elements, including the ocean’s carbon cycle. They are called primary procedures in an aquatic ecosystem. This apparent stability is not real over even quite short geological time scales, but it is real enough over the short life of an organism.
