Les amas sulfur\u00e9s<\/h3><\/div>
Les amas sulfur\u00e9s sont des objets g\u00e9ologiques de petite taille (10 \u00e0 500 m d\u2019envergure, en moyenne) situ\u00e9s par des profondeurs d\u2019eau de l\u2019ordre de 2500 m et qui sont form\u00e9s par l\u2019activit\u00e9 hydrothermale sous-marine. Ces amas sulfur\u00e9s sont riches en m\u00e9taux et constituent une ressource min\u00e9rale convoit\u00e9e. La difficult\u00e9 consiste \u00e0 trouver ces sites g\u00e9ologiques qui constituent de petits objets r\u00e9partis sur des surfaces consid\u00e9rables !<\/p>\n

Un enjeu suppl\u00e9mentaire est de d\u00e9tecter les sites g\u00e9ologiques inactifs dont la biodiversit\u00e9 et la sensibilit\u00e9 environnementale sont beaucoup plus faibles. Or, ils ne sont plus associ\u00e9s \u00e0 des anomalies thermiques et chimiques et ne peuvent donc \u00eatre d\u00e9tect\u00e9s avec les m\u00e9thodes classiques de recherche de ces anomalies dans la colonne d\u2019eau.<\/div><\/div>[\/vc_column_inner][vc_column_inner width=\u00a0\u00bb1\/2″ css=\u00a0\u00bb.vc_custom_1620316124602{margin-top: 20px !important;}\u00a0\u00bb][vc_single_image image=\u00a0\u00bb1371″ img_size=\u00a0\u00bbfull\u00a0\u00bb alignment=\u00a0\u00bbcenter\u00a0\u00bb image_hovers=\u00a0\u00bbfalse\u00a0\u00bb css=\u00a0\u00bb.vc_custom_1620316082768{margin-bottom: 10px !important;}\u00a0\u00bb][vc_column_text css=\u00a0\u00bb.vc_custom_1622021160145{margin-bottom: 10px !important;}\u00a0\u00bb]<\/p>\n

Comment d\u00e9tecter les amas sulfur\u00e9s actifs et inactifs dans un gigantesque oc\u00e9an ?<\/h3><\/div>
C\u2019est pour r\u00e9pondre \u00e0 cette question que nous avons initi\u00e9 des travaux RD en 2014-2015 et imagin\u00e9 le concept de la flotte \u00ab So-Magical \u00bb.
\nNotre flotte So-Magical propose de d\u00e9ployer deux types de v\u00e9hicules : un v\u00e9hicule de t\u00eate<\/strong> et des v\u00e9hicules suiveurs<\/strong> qui suivent les informations de guidage transmises par le v\u00e9hicule de t\u00eate par communication acoustique.<\/div><\/div>[\/vc_column][\/vc_row][vc_row full_width=\u00a0\u00bbstretch_row_content\u00a0\u00bb equal_height=\u00a0\u00bbyes\u00a0\u00bb content_placement=\u00a0\u00bbmiddle\u00a0\u00bb bg_type=\u00a0\u00bbbg_color\u00a0\u00bb bg_override=\u00a0\u00bbex-full\u00a0\u00bb css=\u00a0\u00bb.vc_custom_1618493437315{margin-top: 0px !important;margin-bottom: 0px !important;padding-top: 0px !important;padding-bottom: 0px !important;}\u00a0\u00bb bg_color_value=\u00a0\u00bb#37495f\u00a0\u00bb][vc_column width=\u00a0\u00bb1\/2″ css=\u00a0\u00bb.vc_custom_1618493646666{padding-top: 200px !important;padding-bottom: 200px !important;background-image: url(https:\/\/www.abyssa.com\/abys2021\/wp-content\/uploads\/2021\/04\/abyssa-flotte-auv-1.jpg?id=880) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}\u00a0\u00bb][\/vc_column][vc_column width=\u00a0\u00bb1\/2″ css=\u00a0\u00bb.vc_custom_1616079379776{padding: 45px !important;}\u00a0\u00bb]
<\/div>

Le v\u00e9hicule de t\u00eate<\/h4><\/div>
C\u2019est un v\u00e9hicule grand-fond classique multi-capteurs qui int\u00e8gre un double syst\u00e8me de communication acoustique : le premier de longue port\u00e9e pour communiquer avec le navire de surface, le second de courte port\u00e9e qui sert \u00e0 communiquer avec les v\u00e9hicules suiveurs.<\/div><\/div>
<\/div>

Les v\u00e9hicules suiveurs<\/h4><\/div>
Ce sont des v\u00e9hicules innovants simplifi\u00e9s tant en termes de capteurs de navigation\/positionnement que de capteurs scientifiques embarqu\u00e9s. La simplification des capteurs permet d\u2019avoir des v\u00e9hicules l\u00e9gers et de diminuer fortement le co\u00fbt unitaire du v\u00e9hicule. Pour notre objectif de d\u00e9tection des amas sulfur\u00e9s, nous utilisons la signature magn\u00e9tique sp\u00e9cifique des amas sulfur\u00e9s qui est efficace pour d\u00e9tecter les sites actifs et inactifs. Tous nos v\u00e9hicules So-Magical seront donc \u00e9quip\u00e9s de magn\u00e9tom\u00e8tres 3 composantes.<\/div><\/div>[\/vc_column][\/vc_row][vc_row gap=\u00a0\u00bb35″ content_placement=\u00a0\u00bbtop\u00a0\u00bb bg_type=\u00a0\u00bbbg_color\u00a0\u00bb bg_override=\u00a0\u00bbex-full\u00a0\u00bb css=\u00a0\u00bb.vc_custom_1618496134880{padding: 10px !important;}\u00a0\u00bb bg_color_value=\u00a0\u00bbrgba(55,73,95,0.25)\u00a0\u00bb][vc_column width=\u00a0\u00bb1\/2″][vc_column_text]La flotte vise \u00e0 d\u00e9ployer jusqu\u2019\u00e0 7 v\u00e9hicules naviguant de mani\u00e8re coordonn\u00e9e avec un objectif de cartographie r\u00e9gionale jusqu\u2019\u00e0 3000 m de profondeur.
