Pourtant, \u00e0 bien des \u00e9gards, ils restent un myst\u00e8re.<\/p>\n<\/div>\n<p>Les oc\u00e9ans ont une influence essentielle sur la m\u00e9t\u00e9o et l\u2019atmosph\u00e8re. Ils servent de chauffage \u00e0 accumulation en hiver et de climatiseur en \u00e9t\u00e9.<\/p>\n<p>Les courants oc\u00e9aniques sont comme d\u2019\u00e9normes tapis roulants, qui transportent la chaleur de l\u2019\u00e9quateur vers les p\u00f4les. L\u2019Europe de l\u2019ouest serait aussi froide que le Canada en hiver si le Gulf Stream disparaissait.<\/p>\n<p>Il y a plus de vie dans les oc\u00e9ans que partout ailleurs sur la terre. M\u00eame le plancton, forme la plus t\u00e9nue de vie oc\u00e9anique, absorbe des quantit\u00e9s colossales de dioxyde de carbone. Mais les rejets de p\u00e9trole et de d\u00e9chets toxiques sont un probl\u00e8me grave.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"800\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2004\/07\/Atlantic_ocean_seen_by_Envisat_s_AATSR2\" 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\/esa_multimedia\/images\/2004\/07\/atlantic_ocean_seen_by_envisat_s_aatsr2\/17903677-2-eng-GB\/Atlantic_ocean_seen_by_Envisat_s_AATSR.jpg\" alt=\"Atlantic ocean seen by Envisat&#x27;s AATSR\"><figcaption>L'oc\u00e9an Atlantique vu par l'AATSR d'Envisat<\/figcaption><\/figure>\n<p>Les satellites conviennent parfaitement pour l\u2019\u00e9tude et la cartographie des vastes oc\u00e9ans.
