Variations of the ratio fluorescence in vivo/chlorophyll a and its application in biological oceanograpy

23 pages, 9 figures, 11 tables[EN] The changes of the ratio fluorescence in vivo/chlorophyll a a were measured on cultures of Skeletonema costatum grown in nitrogen and silica- limited chemostats. The ratio was different for both limitations. [...] Thalassiosira fluviatilis, Dunaliella tertiolecta[ES] Desde el trabajo de Lorenzen en 1966 "Método para medir en continuo las concentraciones de clorofila en vivo", la medidad de fluorescencia in vivo se ha convertido en una de las medidas de rutina de la Oceanografía biológica.
