- Artificial seawater
Artificial seawater (or ASW) is a mixture of dissolved mineral salts (and sometimes
vitamin s) that simulatesseawater . Artificial seawater is primarily used inmarine biology and marine aquaria, and allows the easy preparation of media appropriate for marineorganism s (includingalgae ,bacteria ,plant s andanimal s). From a scientific perspective, artificial seawater has the advantage ofreproducibility over natural seawater.Example
The tables below present an example of an artificial seawater preparation devised by Kester, Duedall, Connors and Pytkowicz (1967) [Kester, D. R., Duedall, I. W., Connors, D. N. and Pytkowicz, R. M. (1967). [http://aslo.org/lo/toc/vol_12/issue_1/0176.pdf Preparation of Artificial Seawater] . "Limnology & Oceanography" 12, 176—179.] . The recipe consists of two lists of mineral salts, the first of
anhydrous salts that can be weighed out, the second of hydrous salts that should be added to the artificial seawater as a solution.While all of the compounds listed in the recipe above are inorganic, mineral salts, some artificial seawater recipes, such as Goldman and McCarthy (1978) [Goldman, J. C. and McCarthy, J. J. (1978). [http://aslo.org/lo/toc/vol_23/issue_4/0695.pdf Steady-state growth and ammonium uptake of a fast-growing marine diatom] . "Limnology & Oceanography" 23, 695–703.] , make use of trace solutions of
vitamin s or organic compounds.References
