Iron deficiency in micro-sized diatoms in the Oyashio region of the Western subarctic Pacific during spring

Iron deficiency in micro-sized diatoms in the Oyashio region of the Western subarctic Pacific during spring

In order to detect iron (Fe) stress in micro-sized (20-200 µm) diatoms in the Oyashio region, western subarctic Pacific during spring, immunological ferredoxin/flavodoxin assays were applied to samples collected from the surface layer in May 2005. Concomitantly, the community composition of the micr...

Zusammenfassung:In order to detect iron (Fe) stress in micro-sized (20-200 µm) diatoms in the Oyashio region, western subarctic Pacific during spring, immunological ferredoxin/flavodoxin assays were applied to samples collected from the surface layer in May 2005. Concomitantly, the community composition of the micro-sized phytoplankton and hydrographic conditions, including dissolved Fe and macronutrient concentrations, were also examined. Chlorophyll (Chl) a concentrations were
