On Thursday, September 16, 2021, crew B of the Beautemps-Beaupré hydrographic and oceanographic vessel (BHO) completed their hydrographic and geophysical surveys, which began in early August in the Gulf of Lion. Return on this mission which contributes to a better knowledge of the seabed.
Using its sounders placed under its hull as well as a towed sonar and magnetometer, the Beautemps-Beaupré covered an area of 1,700 km2 and gathered data that will be processed and analyzed at within the Hydrographic and Oceanographic Service of the Navy, SHOM. The use of the data collected will make it possible to update the maps and information held by the French Navy on the seabed in order to secure the navigation of the vessels.
Two wrecks were relocated, while around thirty sediment samples were taken by dumpster, on places of interest identified by acoustic imagery.
Long centered on land, sea and air environments, the conflict has spread to exo-atmospheric and cyber environments, but also to the deep seabed, which represents a new strategic issue for France. BHO Beautemps-Beaupré’s data collection missions provide better knowledge of the area in order to be able to intervene quickly in the event of a potential threat.
