New release of the MEOP-CTD database

A new release of the MEOP-CTD database is now available. In this new release, about 80 CTD-SRDL tags have been added.

The data processing has been improved, with in particular two additional steps ensuring a better accuracy of salinity data:

  • A thermal cell effect correction has been applied on the entire database. Details of the method can be found in the following submitted manuscript:
    Mensah, V., Roquet, F., Picard, B., Pauthenet, E., Guinet, C., 2017.  A correction methodology for the thermal mass induced-errors of CTD tags mounted on marine mammals. In review in the Journal of Atmospheric and Oceanic Technologies. [DOC]
  • A density inversion removal algorithm is also applied, which seeks the minimum adjustment on the salinity profile to achieve neutral stability. The method is described in: Barker, P. M. and McDougall, T. J., 2017. Stabilizing Hydrographic Profiles with Minimal Change to the Water Masses. Journal of Atmospheric and Oceanic Technology, 34:1935-1945. doi: 10.1175/JTECH-D-16-0111.1

New data formats are also proposed, which hopefully will facilitate the use of our database by the largest number. In particular, a netCDF file version of data with profiles interpolated on a regular vertical grid is now available. Furthermore, the csv format is now proposed on a regular vertical grid as well.

And don’t hesitate to send us feedbacks on your use of the MEOP-CTD database !!

Finally, you can follow the MEOP project on ResearchGate if you want to be the first to hear about the latest news.
