SeaBird SBE CTD, oxygen and SeaTech Fluorimeter probes were assembled on the bottom of a 24 Niskin Bottle Caroussel Sampler operated by the ISMAR team..
On some of the stations the water column was sampled at different depths. A minimum of 2.5L of water per sampling level was immediately filtered by GF/F filters and deep-frozen stored.
Immediate Quality Control and calibration of S and Oxygen data were done by a Model 8400B Autosal Guildline Salinometer and by Shott Gerate Titronic T100 and Titronic Controller 1200.
Nutrient, Clorophyll and other analysis on the filtrates are undergoing in the laboratory.
Table 5 shows the localization of the stations.
