Figure 5. Projected change in Antarctic krill habitat in the study area by the late 21^st Century.

Relative GGP (GGP for the period 2070–2099 divided by estimated current GGP) (A) and relative growth area (growth area for the period 2070–2099 divided by estimated current growth area) (B), calculated for the study area (Fig. 1B). Results were calculated across multiple models using bias-corrected SSTs from RCP2.6, RCP4.5 or RCP8.5, and observed chlorophyll-a concentrations reduced by 50% (CHL_o-50%), observed chlorophyll-a concentrations (CHL_o), or observed chlorophyll-a concentrations increased by 50% (CHL_o+50%). The assumed Antarctic krill starting length was 40 mm and the error bars show the between-model standard deviation.
