QPS at GeoHab 2014 and Update on the Backscatter Working Group
QPS staff and local agent Acoustic Imaging recently attended, exhibited, and presented a poster at the GeoHab Conference in Lorne, Australia, May 6th - 8th 2014, and supported the meeting as a sponsor. The GeoHab meeting brings together an international community of marine scientists interested in geological and biological habitat mapping; QPS has supported this meeting nearly every year since 2007. Dr. Jonathan Beaudoin of QPS presented a poster that would be of interest to many of our clients, titled "Recent Improvements to Seafloor Image Acquisition and Processing Procedures for R2Sonic Multibeam Echosounders" – click to view and download a PDF of the poster. For more information on this year's meeting, including presentation abstracts, please see the GeoHab 2014 website.
At the 2013 meeting in Rome, QPS co-organized a workshop titled "Multibeam Backscatter – State of the Technology, Tools, & Techniques". The workshop gathered nearly 100 scientists, engineers, and other professionals interested in backscatter. The primary recommendation emerging from that workshop was the need for standardization of the acquisition and processing of sonar backscatter data provided by multibeam echosounders. As a result of the workshop, the Backscatter Working Group was formed with the goal of creating a set of recommendations and guidelines for acquisition and processing of backscatter measurements by seafloor-mapping sonars. Since then, the group has grown to over 90 interested individuals, with a core group coordinating the authorship of the recommendations and guidelines document.
Since the 2013 workshop, the group has completed an early draft. In Lorne, a presentation on the status of the document was given as part of the session focusing on acoustic backscatter. There was also a dedicated Backscatter Working Group meeting, where the chairing group met with other members and interested parties to discuss the existing draft document and the schedule for completion. Thirty people attended the meeting, including sonar manufacturer representatives, software representatives, and backscatter users. QPS continues to be an active member of this group and a participant in the development of the recommendations and guidelines.

The Backscatter Working Group is open to all interested parties, and is actively looking for anyone who wants to play a role in the development of the document. In particular, the group is currently soliciting feedback on user need. If you would like to read more about the group, or if you would like to be added to the group, please visit the website for background and contact information: http://geohab.org/BSWG/. A survey on user need is posted on the site, we encourage anyone using backscatter to fill it out: http://geohab.org/bswg/bswg_participation/#UserNeeds.
