RQM - CTD Data From the Coriolis II Concerted Mission (MAP2023): PLAINE

10.26071/34b9-46cd-a9a9-9b63517349be

The concerted mission on the Coriolis II in July 2023, financed by the PLAINE program of the Réseau Québec maritime (RQM), aimed to acquire and update strategic knowledge of Quebec's maritime territory. This mission enabled a wide-ranging acquisition of multidisciplinary data for 9 projects focusing on the study of the impact of commercial navigation on ecosystems, and the search for technological solutions to reduce the impact of ports and maritime transport on the environment.

Vertical profiles of CTD data (conductivity, temperature, depth) were produced in the water column at 30 stations in the Saguenay Fjord (from the town of Saguenay), the Maritime Estuary and the Gulf of St. Lawrence ( up to south of Anticosti Island). These profiles were taken from the surface to a maximum distance of around 5 m from the seabed. They include measurements of temperature, salinity, density, dissolved oxygen, pH, fluorescence, light transmission, vertical stratification and sound velocity in seawater. Discrete water samples were taken at various stations and depths to compare CTD's direct measurements with laboratory analyses of dissolved oxygen concentration (49 samples, 11 stations, Winkler chemical titration), chlorophyll a concentration (53 samples, 29 stations), and salinity (32 samples, 31 stations). These comparisons were used to adjust the calibration of dissolved oxygen, fluorescence and salinity data from the CTD.
