Fig. 2: Examples of front’s influence on phytoplankton communities.
From: Shift in phytoplankton community composition over fronts
Satellite snapshot of (A) SST and (B) its associated Heterogeneity Index (HI), of (C) total Chl-a concentration and of the relative concentrations of (D) prokaryotes, (F) diatoms and of (E) the sum of five other eukaryotes in the subpolar biome. Note a different color scale is used for prokaryotes. Frontal regions are delineated by the red contour, which corresponds to a HI threshold of 5. The labels “Front 1” and “Front 2” highlight two distinct frontal features: one oriented north-south (Front 1) and the other oriented east–west (Front 2). Both features are visible in the sea surface temperature (SST) field and converge in the upper right corner of the panel.
