September 8, 2020 (Google Translation) – After taking over in Brest at the end of July, the A crew of the Beautemps-Beaupré hydrographic and oceanographic building (BHO) is back from the North Atlantic where it continued the hydrographic work started by the B crew.
This work is fully in line with the strategic “knowledge and anticipation” function. Concretely, it is a question of maintaining a detailed knowledge of the environment of the marine environment of this region in order to be able to better plan and conduct operations there. It is no less than an area of 33,000 km², ie more than the area of Brittany, which has been the subject of bathymetry and geophysical work by the BHO in recent months.
The study of the water layer is carried out in particular by buoys equipped with measuring instruments. These sensors, launched and retrieved from the vessel, were left adrift on the high seas for several months. The acquisition of bathymetric and geophysical data carried out by the sailors and engineers of the Atlantic Hydrographic and Oceanographic Group (GHOA), an entity of the Hydrographic and Oceanographic Service of the Navy (SHOM), requires great precision in the maneuver of the vessel and the operation of the installations. Thus, in these waters where the weather is often capricious, the crew and the machines of the Beautemps-Beaupré must show particular resilience to carry out the “Narval” mission to its end.
