October 9, 2019 (Google Translation) – Deployed in the Indian Ocean since February 2019, Beautemps-Beaupré Hydrographic and Oceanographic Building (BHO) is progressively returning to Brest. After his ascent of the Red Sea, he crossed the Suez Canal on September 17th.
Beyond the various valued transits, including individual training, continuous bathymetric measurements using multibeam sounders (SMF) and bathythermic soundings, several hydro-oceanographic surveys were conducted in the Indian Ocean and Red Sea by both crews. of the building and their detachments of hydrographers. From February to the end of March, crew B deposited several moorings of oceanographic sensors near the straits of Bab-el-Mandeb, surveyed the Gulf of Tadjoura in Djiboutian waters, then conducted the “Varuna” campaign at sea. Arabia, aiming to study the formation of the Indian Ocean by surveying the “Owen transformant” (boundary between the Somali and Indian tectonic plates).
At the end of March, after a short shift at Salalah (Sultanate of Oman), crew A took over the building, to continue the work in the Arabian Sea (Carlmag campaign of geophysical measurements) and lead the campaign. Physindien 2019 “, to improve the oceanographic knowledge of the region and models of sonar range predictions for the benefit of units operating in the area. Subsequently, the BHO began its work in the southern hemisphere, especially the Scattered Islands and the reefs of the Mozambique Channel.
After four months of preparation on land, the crew B rallied at the end of July the island of Reunion to take over the building and finalize the hydrographic surveys around Madagascar, consisting mainly of work on the bench of the Star, on the volcanic zone off Mayotte and on the French islands of Europa and Juan de Nova. All of these surveys will improve the mapping of the area and secure the access routes and anchorage areas of the Éparses Islands, particularly for the supplies made by the Champlain Overseas Support and Assistance Building (BSAOM).. After a few stops in Madagascar, the BHO then began its ascent of the Indian Ocean to recover the anchorages deposited seven months ago around Bab-el-Mandeb, then transit towards the Suez Canal.
