CTD Data From the Winter Concerted Mission Aboard the CCGS Amundsen (MHG2024): Mission Horizon Glacé 2024 | Données CTD de la mission concertée hivernale à bord du NGCC Amundsen (MHG2024) : Mission Horizon glacé 2024

These profiles were made with a SeaBird 911plus CTD-rosette from around 2 m from the surface to maximum depths of 55 to 214 m (stations 29 and 33 respectively). Continuous measurements of temperature, electrical conductivity (salinity), pressure, oxygen concentration, fluorescence, light attenuation, and irradiance were taken in the water column.

Measurements from these probes were calibrated for dissolve oxygen concentration (Winkler chemical titration), fluorescence (chlorophyll-a concentration), and salinity (Guildline 8410A salinometer) from discrete water samples taken at the different stations. Transmissivity was normalized to 100%, and irradiance measurements were corrected according to the reference irradiance measured at the surface.
