Carte de la contamination du plancher oc\u00e9anique autour du puits Mancondo o\u00f9 la plate-forme p\u00e9troli\u00e8re Deepwater Horizon op\u00e9rait dans le golfe du Mexique. Les points indiquent les coraux affect\u00e9s. En bas \u00e0 droite se trouve la structure mol\u00e9culaire de l\u2019hopane (Image courtoisie de G. Burch Fisher.)<\/p><\/div>\n

Apr\u00e8s la catastrophe environnementale de Deepwater Horizon en 2010, les chercheurs ont perdu la trace de pr\u00e8s de 2 millions de barils de p\u00e9trole sur les 5 millions qui avaient fui dans le golfe du Mexique.<\/p>\n

Une nouvelle \u00e9tude estime maintenant qu\u2019une bonne partie de ces 2 millions de barils se sont d\u00e9pos\u00e9s au fond du golfe \u00e0 une profondeur de 1,5 km. Les auteurs ont pr\u00e9lev\u00e9 des carottes de s\u00e9diments et ont regard\u00e9 la concentration d\u2019hopane, un biomarqueur du p\u00e9trole brut.<\/p>\n

Leur analyse montre que suite au d\u00e9versement, une partie du p\u00e9trole est rest\u00e9e suspendue en eaux profondes avant de se d\u00e9poser sur le plancher oc\u00e9anique.<\/p>\n
