CTD data were obtained by a Sea Bird SBE 911 probe, carrying C,T,Fluorescence, Oxygen, Beam attenuation and transmission sensors. Table A2 in the appendix shows the position of the stations. The binary data were converted to ascii and bin-averaged 0.25 dB by the Sea Bird SBEProcessing program. Data were then converted to the 'spreadsheet-format' by a Perl and Bash script and imported and processed by the ODV package ODV.
Water sampling was obtained by firing the 24 bottles of the General Oceanic's Caroussel. The sampled water was filtered and stored for Nutrient and Chlorophyill analyses (Table A3 in the Appendix).
Biological samples for phyto and zoo plankton were taken by net samplers, among them the NANSEN and WP2 models.
Water transparency was measured by Secchi Disk.
