Summary: | We have determined planktonic community N2 fixation, Trichodesmium abundance, the concentration and vertical diffusive flux of phosphate, and satellite-derived estimates of atmospheric concentration of dust along two longitudinal transects in the eastern subtropical North Atlantic during November 2007 and from April–May 2008. Trichodesmium abundance was particularly low (,3 trichome l 21) during the spring 2008 cruise, when low sea surface temperatures were recorded and vertical stratification was less marked. However, community N 2 fixation was always measurable, albeit low compared with other regions of the tropical Atlantic. The average |
