In total, 44 vertical CTD-hauls were conducted. The CTD system used was a Sea-Bird Electronics Inc. SBE 19plus, attached to a SBE 55 Carousel Water Sampler containing 6 x 4-liter bottles. The system was equipped with: single temperature and conductivity probe (SBE 7245), a pressure sensor (Digiquartz), and a fluoroscence sensor (Wetlabs FLNTU, SN 0773). The sensors were pre-calibrated by the manufacturers. The data were recorded with the Seasave 7.22.2 software and processed using SeaBird SBE Data Processing software.
