Fig. 14.8 Map indicates P* concentrations (P concentrations in excess of phytoplankton require-
ments) in Atlantic surface waters and the line on map indicates the sampling ship's transect. Graphs
show dissolved iron and phosphate concentrations and nitrogen fixation rates in the Atlantic ocean
surface waters (Moore et al. 2009 ); yaxis on graphs is latitude with negative numbers being south
of the equator
