Sampling area, Lagrangian buoys and zooplankton tows. (a) Iberian-Canary current eastern upwelling system showing the sub-regions sampled (orange boxes) and the main currents (AC, Azores Current; CC, Canary current; PC, Portugal Current; SC, Slope current). (b) Trajectory of the buoys during the first (L1) and second Lagrangian experiments (L2) in Iberian waters overlaid on sea surface temperature (SST) at the end of L2 (July 20th). The asterisk shows the location inside the Ría de Vigo where O. vulgaris paralarvae were collected on September 22nd 2010. (c) Zooplankton samples were collected during CAIBEX-I off the Northwest coast of the Iberian Peninsula. Samples S1–S7 correspond to L1, carried out in the open ocean (blue), and S13–S20 to L2, carried out over the continental shelf (green). (d) The trajectory of the buoy during the third Lagrangian experiment in Moroccan waters (L3) overlaid on SST at the beginning of the experiment (August 24th). (e) Zooplankton samples collected during CAIBEX-III over the continental shelf off Morocco (green), following the upwelling filament during L3 (red), in the area affected by the upwelled water over the continental slope (orange) and in the open ocean (blue). In (c) and (e), the light squares and dark circles represent samples that were taken either during the day or night, respectively. Maps created with R (version 4.0.3; https://www.r-project.org/).
