Abstract:
Data were collected from 9 to 12 of May of 2011 on board RV Atlantic Explorer from a section across a wind-shear convergent front south of Gran Canaria Island (Canary Island). In order to assess both spatial and temporal variability at submesoscale range, a section consisting in 6-7 oceanographic stations, separated ~4 km (25 km in total), was entirely sampled every 24 h, during a 96 h period (there are no data for 72h). At each station discrete water samples were collected for chlorophyll a, nutrients and picophytoplankton abundances at six levels, from surface to 150 m, including the deep chlorophyll maximum (DCM) by means of CTD mounted onto an oceanographic rosette implemented with six Niskin bottles of 12 L.
