From: Marine heatwaves exacerbate climate change impacts for fisheries in the northeast Pacific
Projected changes in sea surface temperature (A,B) and the impact indicators (biomass, latitudinal centroid and depth centroid; C–H) of the 22 studied fish stocks in the three large marine ecosystems (Eastern Bering Sea - EBS, Gulf of Alaska - GoA, California Current - CC) of the northeast Pacific during MHWs (left panels) and due to long-term climate change from 1981 to 2100 (right panels). Changes in sea surface temperature and impact indicators during MHWs were expressed relative to the spline-smoothed ensemble-mean of the same time period. In contrast, long-term climate changes were calculated from linear regressions over the 1981–2100 period, with the rate of change (slope of the regression) expressed as change per decade. Negative depth centroid shifts in G-H indicate species’ average distribution that were projected to be deeper.
