Fig. 3: Equatorial and subtropical gyre hotspots: Linear trends of frontal frequency (Ffreq), frontal density (Fdens), frontal strength (Fstre), and regional log chlorophyll (RChl) anomaly.
From: Global trends of fronts and chlorophyll in a warming ocean
a Hotspots (colored lines) and the equatorial (red shading) and subtropical gyre (yellow shading) regions. Panels b through e: Anomaly trends of (b) Ffreq, (c) Fdens, (d) Fstre, and (e) RChl. In b–e, data share x-axis labels; standard errors are shown with black bars; statistically significant trends (above the 95% confidence level) are marked with an asterisk.
