Data presented here were collected during the cruise MSM65 (Project GREENHAB II) with RV Maria S. Merian from St. John's, Canada to Nuuk, Greenland (June 26th, 2017 to July 18th, 2017). In total, 50 vertical deep CTD-hauls were conducted. The CTD system used was a Sea-Bird Electronics Inc. SBE 911plus probe (SN 09-1266: SN 5828 / SN 4529). The CTD was attached to a SBE 32 Carousel Water Sampler (SN 32-1119) containing 24 x 20-liter Ocean Test Equipment Inc. bottles. The system was equipped with double temperature (SBE 3) and conductivity sensors (SBE 4), a pressure sensor (Digiquartz), an oxygen Optode (Aanderaa Optode 4831F), an altimeter (Benthos), and a chlorophyll fluorometer combined with a turbidity sensor (WET Labs ECO_AFL FL). The sensors were pre-calibrated by the manufacturers. Data were recorded with the Seasave V 7.23.2 software and processed using the SeaBird SBE Data Processing. Data were despiked, and also visually checked. The ship position was derived from the shipboard GPS-system linked to the CTD data. The time zone is given in UTC. Salinity was quality checked by reference samples [n=42], measured with an Optimare Precision Salinometer (OPS S/N 003) 4 month after the cruise (S1: R² 0.9997, S2: R² 0.9997).
