picture info	Diatom A diatom (Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of ...

	Bacillariaceae Bacillariaceae is a family of diatoms in the phylum Heterokontophyta, the only family in the order Bacillariales. Some species of genera such as ''Nitzchia'' are found in halophilic environments; for example, in the seasonally flooded Makgadikgadi Pans in Botswana. Genera This family includes these genera: '' Allonitzschia'' (1) ''Bacillaria'' Gmelin (155) '' Crucidenticula'' (8) '' Cylindrotheca'' Rabenh. '' Cymbellonitzschia'' Hustedt in A.Schmidt et al.

	Cosmopolitan Distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

	Fragilariopsis Kerguelensis ''Fragilariopsis kerguelensis'', is a pennate diatom native to the Southern Ocean. It has been characterized as "the most abundant diatom in the Antarctic Seas". Description ''Fragilariopsis kerguelensis'' is a unicellular, phototrophic, microalga with a range in size of 10 - 80 μm. It is encased in a heavily silicified cell wall, called the frustule, and is identified by its unique theca, raphe and striations, which distinguish it from other diatoms. They are native to pelagic environments of the Southern Ocean within a temperature range of -1° to 18° C. ''F. kerguelensis'' is known to form community chains that consist of 20-100 cells and can be up to 300 μm long. Use as a paleoceanographic proxy ''Fragilariopsis kerguelensis'' is well preserved in the fossil record and commonly referenced as a paleoceanographic or paleoclimatic proxy. ''F. kerguelensis'' comprises the largest deposit of biogenic silica in the world (~75%) despite only accounting for 20% of ...
