Parametric Sub-Bottom Profiler for AUVs

Abstract

Autonomous underwater vehicles (AUV) are fast becoming viable survey platforms. With this growth, new survey tools have emerged. The Naval Oceanographic Office's (NAVOCEANO) profiler for the Subsurface Autonomous Mapping System (SAMS) AUV (PFRS) was developed by Omni Technologies Inc. (OTI) to provide high-resolution, sub-bottom imagery (data). AUVs have stringent requirements in electrical power budget, size and weight requiring survey sensors that are smaller, lighter, autonomous and more energy efficient than typical survey tools. However, AUVs are excellent survey platforms due to their stability and ability to operate close to the target. Sub-bottom profilers are used by surveyors to obtain information on surficial marine sediments in cable route surveys, for pipeline route surveys, piling installations, pipeline burial and scour surveys, salvaging operations or any operation where knowledge of bottom and sub-bottom sediments is critical.
