Fig. 4: Poleward expansion of Emiliania Huxleyi (EHux) in the European Arctic Corridor.
From: Faster Atlantic currents drive poleward expansion of temperate phytoplankton in the Arctic Ocean
Comparison between 1998 (a) and 2015 (b). The initialization (inoculum) of virtual particles in March are illustrated by brown dots. During 6 months, particles drift with the Norwegian Atlantic Current (red arrows) as the ocean seasonally warms as illustrated by the northward expansion of the 4 °C isotherm. In August, the particles end up in positions indicated by the red dots. In the background, remotely sensed PIC indicating coccolithophore biomass in summer (July–August–September) is shown in blue colors. Areas with no data are in dark gray.
