Software download and FAQ

OCTOPUS is a multi-format Checker, Converter and Splitter tool.


  • OCTOPUS converts files in a given SeaDataNet format to another SeaDataNet format (e.g.: ODV to netCDF, netCDF to ODV, MedAtlas to NetCDF, MedAtlas to ODV)
  • OCTOPUS checks the ODV SDN variant formats for biology, microlitter and flow cytometry, it can converts them from ODV variant to ODV variant
  • OCTOPUS has also additional functions such as:
    • Split a multi-station SeaDataNet file into mono-station SeaDataNet files
    • Extract station(s) from SeaDataNet files
    • Convert MGD v81 and v98 to SeaDataNet ODV  files

The following conversions are handled by OCTOPUS:

The Octopus software interface is bilingual (English/French) and the software is fit for use on several platforms : Windows and Linux..

OCTOPUS version (16/04/2020)


  • Update URLs for CDIs, CSRs and NERC vocabularies
  • Allow DPSF P09 parameter as depth below sea surface in MedAtlas files (e.g. core data)
  • Allow exception for ODV files with empty vertical reference (e.g. navigation, contaminants in biota files). These files must contain the following comment in the ODV header: //SeaDataNet file without vertical reference

OCTOPUS version (29/11/2019)


  • in ODV format, bottom depth default value set to empty instead of 0
  • Conversion MGD to ODV: Change the order of the depth parameter

Bug corrections:

  • Use XXXX P06 unit instead of UUUU for text parameters
  • Display variant in the string "Generated By" created by Octopus in the output file
  • Allow usage of the same P01 parameter multiple times in a file (an index is added to the netCDF variable names if needed)
