Aujourd\u2019hui, gr\u00e2ce \u00e0 l\u2019aide des satellites, des centaines de bateaux empruntent le m\u00eame itin\u00e9raire sans conna\u00eetre le moindre incident.<\/p>\n<\/div>\n<p>Pendant la nuit du 14 avril 1912, le marin Frederick Fleet \u00e9tait l\u2019homme de veille du Titanic. Les informations sur les blocs de glace relay\u00e9es par Frederick Fleet \u00e9taient les seules dont disposait le capitaine Edward John Smith pour diriger le paquebot dans les eaux dangereuses du large de Terre-Neuve.<\/p>\n<p>Le naufrage du Titanic a contribu\u00e9 \u00e0 renforcer la s\u00e9curit\u00e9 maritime et a occasionn\u00e9 la cr\u00e9ation de la convention pour la Sauvegarde de la vie humaine en mer et de la Patrouille internationale des glaces.<\/p>\n<p>Le r\u00f4le de la Patrouille des glaces consiste \u00e0 surveiller les mouvements des icebergs et \u00e0 identifier les zones les plus dangereuses. \u00c0 tout moment, des centaines d\u2019icebergs \u00e9voluent dans les eaux de l\u2019oc\u00e9an Arctique. La Patrouille des glaces a pour mission de d\u00e9terminer le nombre d\u2019icebergs susceptibles de d\u00e9river vers le sud et de traverser les couloirs de navigation. Depuis la naissance de la Patrouille des glaces, aucune collision entre un navire et un iceberg n'a eu lieu.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"ESA\/DLR\" data-detail-url=\"https:\/\/www.esa.int\/Media\/Animations\/Baltic_Sea_Animation\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/media\/animations\/baltic_sea_animation\/8598463-4-eng-GB\/Baltic_Sea_Animation.jpg\" alt=\"\"><\/figure>\n<p>\u00c0 l\u2019origine, la Patrouille des glaces avait recours aux vaisseaux de la Marine pour ses missions de routine.
