He has been in charge of the French Hydrographic and Oceanographic Service onboard acoustic systems since 2007,. For SHOM, he mainly focuses on MBES qualifications and training of surveyors. He has been conducting multiple acceptance and qualification surveys at sea.


Tool to Process Sound Velocity Profiles

Hydrographic and geosciences surveys, using acoustic devices, need to use accurate water sound velocity profiles. Because the acoustic path depends on the sound velocity profile (SVP), the use of the most accurate SVP is one of the keys to conducting effective surveys (with multibeams, for instance)...
