JWG M.1: Data and tools exchange

Chair: Pierre Sakic (France)
Affiliation: IERS, GGOS

Terms of Reference

This JWG aims to enable the shareability of the seafloor geodesy data collected by the different working groups worldwide and then give better visibility to these data while respecting the FAIR principles. Indeed, clearly defined exchange standards and effective data sharing might be a solid foundation for concrete exchanges between the research groups working on seafloor geodesy questions, thus initiating future international collaborations and, in the long term, establishing a global underwater geodetic observation network.

Objectives

  • Enable the shareability of the seafloor geodesy data collected by the different working groups around the world;
  • Give better visibility to these data;
  • Respect the FAIR data principles (Findable, Accessible, Interoperable, Reusable).
  • A special emphasis has to be given to the interoperability of seafloor geodetic data,i.e., the possibility to easily use data of one working group with the software of another, for instance.
  • Identify how data can be easily stored in existing repositories or establish expectations for new repositories.
  • Establish community-supported data standards that can be adopted by the repositories/data centers.

Program of Activities

The working group initially discussed a range of seafloor geodetic techniques. Given the considerable interest in GNSS-Acoustic by those who participated in this discussion, it was agreed to start with this technique. Nevertheless, the task force is interested in a wide range of techniques, and will likely revisit other techniques in the future.Techniques of future interest may include:

  • Acoustic ranging
  • Ocean bottom pressure sensors (OBP)
  • Tiltmeters
  • Optical Fiber Strainmeter
  • Seafloor gravimetry
  • Mast Seafloor <> Surface combining GNSS+attitude measurement
  • Multi-beam Bathymetry

It would be highly valuable if other working groups similar to the current one coulde merge within the task force to consider the other techniques mentioned above, like the OBP for instance.
