Extended Data Fig. 9: Projected latitudinal changes in annual phytoplankton biomass production between pre-industrial (1860) and future (2090-2100) conditions, based on alterations in temperature, nutrient supply, mixing, and ocean circulation anticipated under a high warming scenario.
From: Future ocean warming may cause large reductions in Prochlorococcus biomass and productivity
Latitudinal change (%) in depth-integrated biomass production for Prochlorococcus, Synechococcus and the combined total of all other phytoplankton. Results are based on the metabolic thermal response function for Prochlorococcus. Grey line (T + N-) represents changes due to the combination of temperature and nutrient shifts between pre-industrial and future conditions. Black line (T + ) represents changes due solely to temperature shifts, with circulation and nutrient concentrations held at pre-industrial levels (Methods and Supplementary Table 5). Shading represents the longitudinal variation from the mean (SD).
