Conductivity-Temperature-Depth (CTD) profiles obtained in the Baffin Bay at stations GeoB22333-2 and GeoB22365-3 during the MSM66 cruise (22nd of July 2017 – 28th of August 2017). The CTD on-board Maria S. Marian is a Sea-Bird Electronics Inc. SBE 911plus (Temperature sensor SBE 3plus and Conductivity sensor SBE 43). The CTD has a depth rating of 6800 m, measuring conductivity between 0 and 70 ms/cm, temperature between 0 and 35ºC, and pressure between 0 and 10000 psi. The CTD is equipped with an additional sensor for fluorescence (WETLabs ECO FLNTU(RT)D).
