A new deep water multibeam echosounder-TSM 5265

IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259), 2002
The MARION DUFRESNE is a multipurpose oceanographic vessel managed by the French Polar Institute. This vessel is equipped with a new generation deep water multibeam echosounder TSM 5265 using new signal processing for bathymetry and new techniques for imagery and sub-bottom profiling.

Robust Subsea Pipeline Tracking with Noisy Multibeam Echosounder

2018 IEEE/OES Autonomous Underwater Vehicle Workshop (AUV), 2018
Subsea pipelines are crucial offshore assets aiding transportation of oil and gas. Regular inspections are required for assessing their integrity to ensure continual use and avoid possible marine ecosystem damage. This paper proposes a novel real-time algorithm for pipeline detection and tracking at close proximity using only a multibeam echosounder ...

Seafloor Acoustic Backscatter Measurements With Multibeam Echosounders

Proceedings of Offshore Technology Conference, 2010
Abstract This paper is a tutorial on the fundamentals of seafloor acoustic backscatter measurements made with multibeam echosounders. Such measurements are used to infer seafloor geoacoustic properties, including: acoustic impedance contrast at the water/sediment interface, mean sediment grain size, spectral ...

The patch test: a comprehensive calibration tool for multibeam echosounders

OCEANS 2000 MTS/IEEE Conference and Exhibition. Conference Proceedings (Cat. No.00CH37158), 2002
The patch test procedure is the first stage required in any multibeam echosounder survey. The patch test is designed to precisely determine the static configuration of the sonar head (roll, pitch, yaw) and the latency remaining between the reception of the GPS fix and its integration by the acquisition system.
