JWG M.2: GNSS-Acoustic technologies and experiments

Chair: James Foster (Germany)
Affiliation: Commissions 1, 3, 4

Terms of Reference

GNSS-Acoustic techniques allow us to measure positions and displacements of the seafloor – an environment that was previously almost entirely unobserved by geodetic techniques. In the last decade, there have been major advances in technologies and processing approaches that have lead to a burgeoning range of research experiments and technological developments. In this rapidly evolving field, many different groups, both academic and commercial, are exploring new technical approaches and strategies, investigating new study areas, and employing new processing algorithms. Although the cost for seafloor geodetic equipment, deployments, and measurement campaigns has been greatly reduced over the last few years, it remains an expensive frontier of research and development. Consequently, it becomes imperative to ensure that there is a venue for the exchange of information about the latest seafloor geodetic technologies and experiments in order to ensure that efforts are not duplicated, that the best available existing solutions appropriate for a particular problem can be found, that potential partners for collaborative efforts can be identified, and that people able to provide crucial guidance and information can be connected with. The Joint Working Group for“GNSS-Acoustic technologies and experiments” is tasked to develop a publicly available web-based document that will provide key information for all significant completed, ongoing, and upcoming seafloor geodetic experiments, and its enabling technologies.This living document will be available as a resource for all individuals interested in seafloor geodesy and the technologies and projects that have, or will, use this geodetic technique.

Objectives

  • To provide a publicly accessible catalog of GNSS-Acoustic experiments and tech-nologies;
  • To encourage the voluntary listing of relevant technologies and experiments by the PIs and/or companies that are developing/deploying them.

Program of Activities

  • Define the form & structure of the web page that will provide key summary information concerning seafloor techniques, applications, experiments and links to relevant PIs, and companies.
  • Establish the categories, and minimum necessary information fields and optionalsections for inclusion in the web document.
  • Solicit document listings from all known active parties in seafloor geodesy.
  • Publish document for comments and ongoing contributions.
