Average primary production estimates for 1998-2017 and 2080-2099, and time series of primary production in the subtropical biome

Figure 4-3 Mean depth-integrated primary production, (a) 1998–2017, (b) 2080–2099, (c) time series of the area with primary production, <0.3 g C m-2 d-1 in the subtropical biome (red line) and the time series of the area with production ≥1.2 g C m-2 d-1 in the Equatorial Upwelling biome. Dashed white lines in (a) and (b) indicate the biome boundaries. (From Polovina et al. [2011] by permission of Oxford University Press.)
