Abstract

This dataset contains the CTD data collected during the GOMBESSA 6 cruise, from 1 to 12 July 2021, in Corsica, western Mediterranean, jointly by the Andromède océanologie (France) and MARBEC MARine Biodiversity, Exploitation and Conservation (France) teams.

The full-depth CTD profiles were performed using an autonomous SeaBird SBE 19plus V2 SeaCAT Profiler CTD, from the Pionnier vessel belonging to Seaowl France and chartered by the French Navy.

Nine stations, from the depth of 115 m to the surface, were sampled off the Corsica coasts (western Mediterranean basin) between latitude 43.11-43.74 °N and longitude 9.49-9.52 °E.

The acquisition rate was 4 Hz. The accuracy, specified by the manufacturer, were ± 0.005 °C for temperature and ± 0.0005 S/m for conductivity.

The dataset is provided in different formats (CSV, NetCDF, Ocean Data View collection), which contains, for each station the following parameters:


  • Depth [salt_water,m]

  • Temperature [ITS-90,deg-C]

  • pH

  • Salinity, Practical [PSU]

  • Conductivity [S/m]

  • Density [kg/m^3]

  • Oxygen [mL/L]

  • Oxygen_sat [% saturation]

  • Oxygen_umoll [umol/L]

  • Turbidity [NTU]

  • Fluorescence [mg/m^3]

  • Light [PAR/Irradiance]

  • QC (reference: OceanSITES quality flags http://www.oceansites.org/docs/oceansites_user_manual_version1.2.doc)

  • Julian Days and UTC time (yyyy-mm-ddThh:mm:ss.sss)

The ZIP archives contain 1/ a map of stations 2/ the list of the ID stations, geographic coordinates and general metadata 3/ all raw data acquired, for all parameters, in CNV format, 4/ the downcasts and upcasts in CSV format, 5/ the upcasts only in ODV, 6/ NetCDF and 7/ TXT formats, and 8/ two vertical profile graphs including all stations (sea water temperature and oxygen).

All data acquired are publicly accessible without any restriction (under CC-BY licence). The extracted data are accessible from this GOMBESSA 6 landing page with a downloadable ZIP file.
