For 32 SFB 754 cruises near surface temperatures and salinities were collected using the ships' thermosalinograph systems.The four ships on which the major cruises were conducted were equipped with different systems with either one or two 195 thermosalinographs in parallel or in alternating operating mode (see Table C9). All TSG data were cross-calibrated againstthe calibrated CTD data at the depth of the seawater intake for the TSG systems.
