    Histograms showing the number of occurrences of binned δ15N for (a) Synechococcus, (b) Prochlorococcus, and (c) eukaryotic phytoplankton at all depths and all stations

    Histograms showing the number of occurrences of binned δ15N for (a) Synechococcus, (b) Prochlorococcus, and (c) eukaryotic phytoplankton at all depths and all stations. Note the difference in y axis scale between the prokaryotes (Figures a and b) and eukaryotes (Figure c). Data from PITS in July 2009 (“July PITS”) and Hydro Station S in July 2008 (“July Hydro S”) are from Fawcett et al. [].

  • Simulated net carbon uptake by lichens and bryophytes from Porada et al. [2013]

    Simulated net carbon uptake by lichens and bryophytes from Porada et al. [2013]

    Simulated net carbon uptake by lichens and bryophytes from Porada et al. []. (a) Lower bound of the model estimates, obtained by equal weights for all surviving strategies in each grid cell. (b) Upper bound, corresponding to the net carbon uptake of the most productive strategy in each grid cell. Gray areas denote zero carbon uptake.

  • Biogeochemical cycling of Dissolved Zinc along the GEOTRACES South Atlantic transect GA10 at 40°S

    Biogeochemical cycling of Dissolved Zinc along the GEOTRACES South Atlantic transect GA10 at 40°S

    The stations sampled for dissolved Zn along section GA10 during two UK GEOTRACES cruises D357 (red circles) and JC068 (black circles). Stations 1, 2, and 3 were reoccupied during JC068.

  • Change in monthly mean chlorophyll a concentration resulting from precipitation events (ΔNChlaprcp, %) for January to December

    Change in monthly mean chlorophyll a concentration resulting from precipitation events (ΔNChlaprcp, %) for January to December

    Change in monthly mean chlorophyll a concentration resulting from precipitation events (ΔNChlaprcp, %) for January to December. The red and yellow colors indicate the enhancement of chlorophyll a concentration, whereas the blue indicates the depression of chlorophyll a. The contour lines indicate the climatological monthly mean NO3− concentration (μM).
