Abstract:
The CTD data on cruise MSM83 contain oceaninc measurements of temperature, salinity, oxygen and pressure at 104 stations. The data were collected with the research vessel Maria S., Merian during cruise MSM83.
Region: subpolar Northa Atlantic, 11°W-47°W, 39°N-53°N
Ports: Las Palmas - St. John's
Date: May 17 - June 15, 2019.
The data where collected by a CTD device of type SBE 9. The CTD was mounted to a metal frame with 22 water sample bottles, which was lowered from the sea surface down to 10 m above the seafloor. The sampling frequecy was 24 Hz, the raw data were then interpolated on 1 dbar intervals. Salinity and oxygen data from the CTD were calibrated by comparison with samples from the water bottles. The bottle salinity was analysed by a salinometer of type Guildline Autosal 8400A, bottle oxygen samples by Winkler titration. The accuracy of the calibrated CTD measurements is: 1 dbar for pressure, 0.001 °C for temperature, 0.0025 for salinity, 3.0 µmol/kg for oxygen.
