Physical oceanography, picoplankton biomass, chlorophyll a and nutrients during RV Atlantic Explorer cruise ESTELA

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 CTD data and 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.
