(a) Schematic representation of the location of stations sampled during cruise tracks depicted on Ocean Data View (http://odv.awi.de)45, map. (b–h) Box-plots displaying for each dataset: (b) Salinity (in g.L−1), (c) Temperature (in °C) and concentrations (in µmol.L−1) in (d) Nitrate, (e) Nitrite, (f) Phosphate, (g) Chlorophyll a (Chl a) and (h) Silicate. (i) Variables factor map and (j) Individuals factor map of the principal component analysis (PCA) performed using standardized quantitative values of the following quantitative ancillary variables: temperature (in °C), salinity (g.L−1), chlorophyll a (in µM), silicate (in µM), nitrite (in µM), nitrate (in µM) and phosphate (in µM); qualitative data (depth of Deep Chlorophyll Maximum (DCM) and distance to shore) were used as illustrative factors.
