6th Workshop "Seabed Acoustics" 2013
The 6th user workshop "Seabed Acoustics" took place November 14/15, 2013 in "Hotel Neptun" in Rostock-Warnemünde (Germany).
Thanks to all of the more than 100 attendees from 14 countries for coming and to the speakers for giving very interesting presentations on a wide range of applications. During the breaks and the traditional dinner we had a lot of nice discussions and everybody enjoyed these opportunities to exchange experiences and for networking.
At the second day there was a live demo of different survey eqipment on a river boat.
For pictures on the euipment demonstration see below.
On the first day of the workshop there were presentations given on a wide range of applications of underwater acoustic equipment:
- Thomas Dehling (Federal Maritime and Hydrographic Agency, BSH, Germany):Acoustic versus Optic – remote sensing in hydrography
- Michiel Künzel (deep bv, The Netherlands):Cable tracking using high resolution parametric echo sounders
- Christian Maushake (Federal Waterways Engineering and Research Institute, Germany):How deep does an anchor penetrate the seafloor?
- Greg Sambrook Smith et al. (University of Birmingham, United Kingdom):Imaging river dune and bar deposits using a parametric echo sounder, examples from the Rio Parana and Rio Bermejo, Argentina
- Chloé Pennec (University of Perpignan, France): The use of high-resolution seismic reflection regarding coastal processes and engineering expertise
- Koen Geirnaert (dotOcean nv, Belgium):
Mud layers characterized by free fall penetrometers and a parametric echo sounder
- Stéphane Polteau et al. (Volcanic Basin Petroleum Research AS, Norway): Sub-bottom profiling for better seafloor seep sampling results in frontier basins around Greenland

Survey Equipment Demo at Sea
During the second day equipment of different manufacturers was shown in operation on a river boat. All acoustic equipment (SBP and MBES) was operated simultaneously without any interference visible in the data sets.
- Innomar standard-rov parametric sub-bottom profiler (new generation 2013),
- Innomar light parametric sub-bottom profiler,
- Innomar quattro parametric multi-transducer sub-bottom profiler for high-resolution data acquisition and 3D visualization,
- Remotely operated Unmanned Surface Vehicle (USV) "MESSIN"
- Teledyne RESON SeaBat T20-P multibeam echosounder,
- Ship Motion Control (SMC) motion sensor IMU-008 (HRP sensor),
- FRAHM sediment sampler (ground truthing tool).
Thanks to all people who made this workshop a success!
