Sub-Arctic no more: Short- and long-term global-scale prospects for snow crab (Chionoecetes opilio) under global warming
Fig 10
Snow crab potential habitat index by Ice Region.
Black points show ice extent areas based on historic NOAA satellite observations of maximum minus minimum ice extent in a calendar year. Black lines are loess regression curves. Blue and red solid lines are best- and worst-case CO2 emission scenarios projections, with the index calculated from model point estimates of maximum and minimum monthly ice extent values. Thin-dashed black lines show upper and lower 95% confidence interval bounds for model fits. Corresponding thin-dashed blue and red lines show upper (95th percentile) and lower (5th percentile) levels of predicted ice extent for a given calendar year. Lowest levels of ice predictions equal to zero in the worst-case scenario model run are plotted below zero for presentation.
