The bottle data on cruise MSM73 contain measurements of pressure, temperature, salinity and oxygen (derived from CTD values at the location of closing bottles) and direct measurements of oxygen, CFC-12, SF6 and the noble gases helium and neon. The data were collected with the research vessel Maria S. Merian. Region: subpolar North Atlantic, 11°W-54°W, 44°N-61°N, Ports: Cadiz - St. John's, Date: April 06 - May 22, 2018. The bottle data were collected by an SBE 32 water sampler system in connection with a SBE 911 plus CTD. The CTD was mounted to a metal frame with 22 Niskin bottles of 10 l volume, which was lowered from the sea surface down to 10 m above the seafloor. Pressure, temperature, salinity and oxygen data from the CTD were recorded at the time when closing the bottles. In addition, direct samples of salinity and oxygen from the water bottles have been taken to calibrate the CTD data. The accuracy of the CTD measurements is: 1 dbar for pressure, 0.001 °C for temperature, 0.003 for salinity, 4.0 ...
