ts01.pdfPDF document58KPresent area of the modeled ecological biomes (calculated for years 1980-1999) and the response of the biome areas to global warming in the 21st century. Areas are given in 10^12 m^2. Table columns shows the present area of the biomes, followed by the net change in areas and the % change in areas. Net area change is the difference between the model average warming conditions (2080-2099) minus present conditions (1980-1999). % change in area is the percent change in area relative to the (1980-1999) mean area. Note that the average control biome areas for years (1980-1999) are used for all calculations in the main body of the paper, and are illustrated in Figure 5 of the main text
gbc_20108_fs01_121313.pdfPDF document81KGlobal maps of the limiting nutrients at the ocean surface at ÒpresentÓ (averaged over the control period, years 1980-1999) and in the future (averaged over years 2080-2099) for (a,b) diatoms, (c,d) small phytoplankton, and (e-f) diazotrophs.
gbc_20108_fs02_121313.pdfPS document510KZonal averages of: (a) Relative (fractional) abundance of small phytoplankton (black) and diatoms (red) for years 1980-1999 (no units); (b) Trend in relative abundance of phytoplankton from 1980 to 2100; (c) Nutrient contribution to the 1980-2100 trend in specific growth rate () as calculated from Eq. A6b; (d) Light contribution to 1980-2100 trend in growth rate () as calculated from Eq. A6a. (e) Southward transport of small phytoplankton (black) and diatom biomass (red) in the Southern Hemisphere Atlantic basin in 102 molC/s. Trends in (b,c,d) above are calculated from the respective 1980-2100 modeled linear trends multiplied by 120 years, in units of day-1.
fs03.pdfPDF document821KTemporal trends in (a) surface diatom biomass and (c) surface nutrient limitation calculated from Eq. A3 (Appendix A of the paper). (b) Temporal trend in diatom biomass congruent with the nutrient limitation trend. (d) The residual trend in diatom biomass, or the trend in biomass unexplained by the nutrient limitation trend. Trends are calculated from the 120 years (1980-2100) of monthly data.
fs04.pdfPDF document1436KGlobal maps of the ÒpresentÓ values (average over years 1980-1999) and climate change signal (difference between years 1980-1999 and years 2080-2099) for (a,b) surface iron (nmol/m3); (c,d) Fe vertical advection at the maximum annual MLD in nmol Fe/m2/day; (e,f) Fe horizontal convergence vertically integrated up to the maximum annual MLD (nmol Fe/m2/day). These values were approximated off-line from monthly nitrate and flow values.
