Africa-Press – C\u00f4te d’Ivoire. <\/strong><\/span>Les profondeurs au large de l’Argentine regorgent de richesses naturelles. Une e\u0301quipe de chercheurs a\u0300 bord du navire de recherche Falkor (too) du Schmidt Ocean Institute a longe\u0301 la co\u0302te, de Buenos Aire a\u0300 la Terre de Feu, y de\u0301couvrant 28 potentielles nouvelles espe\u0300ces et des spe\u0301cimens remarquables. Les nouveaux organismes documente\u0301s comptent des vers, des coraux, des oursins, des escargots de mer et des ane\u0301mones de mer.<\/p>\n

L’e\u0301quipage a aussi observe\u0301 le plus grand re\u0301cif corallien de l’espe\u0300ce Bathelia candida identifie\u0301 a\u0300 ce jour. Il couvre au moins 0,4 kilome\u0300tre carre\u0301, ce qui fait que ce re\u0301cif d’eau froide est presque aussi e\u0301tendu que le Vatican. Une dimension pre\u0301cieuse, le Bathelia candida e\u0301tant un refuge pour de nombreuses espe\u0300ces, comme les poissons ou les crustace\u0301s.<\/p>\n

Un cadavre de baleine qui offre des milliers d’anne\u0301es de nourriture<\/b><\/p>\n

A\u0300 3890 me\u0300tres de profondeur, les scientifiques ont e\u0301galement documente\u0301 un cadavre de baleine, le plus profond de\u0301couvert au large de l’Argentine. Si, a\u0300 premie\u0300re vue, se re\u0301jouir de cette de\u0301couverte peut parai\u0302tre morbide, il n’en est rien. En effet, les cadavres de baleines qui coulent au fond de l’oce\u0301an deviennent ensuite des e\u0301cosyste\u0300mes temporaires, offrant abri et nourriture a\u0300 la faune environnante.<\/p>\n

<\/p>\n

Plus pre\u0301cise\u0301ment, les e\u0301chouages de baleines dans les fonds marins \u00ab\u00a0offrent des milliers d’anne\u0301es de nourriture a\u0300 un environnement habitue\u0301 a\u0300 la pe\u0301nurie\u00a0\u00bb, commente dans un communique\u0301 le Schmidt Ocean Institute. Une fois que les chairs ont e\u0301te\u0301 consomme\u0301es, le cadavre devient un substrat ou\u0300 peuvent se fixer des espe\u0300ces.<\/p>\n

Les scientifiques ont aussi eu la chance d’apercevoir une me\u0301duse fanto\u0302me ge\u0301ante (Stygiomedusa gigantea) a\u0300 250 me\u0300tres de profondeur. Ses quatre bras oraux peuvent atteindre une longueur de 10 me\u0300tres. Et cette \u00ab\u00a0me\u0301duse des grands fonds qui peut atteindre la longueur d’un bus scolaire\u00a0\u00bb, remarque le Schmidt Ocean Institute qui pre\u0301cise qu’elle est rare.<\/p>\n

Une VHS quasi neuve<\/b><\/p>\n

Malheureusement, l’e\u0301quipe n’a certainement pas parcouru des fonds marins vierges de toutes activite\u0301s humaines. Elle a mis la main sur des filets de pe\u0302che, des sacs poubelles et, plus e\u0301tonnant, une cassette VHS quasi neuve, preuve \u00ab\u00a0de la longe\u0301vite\u0301 des plastiques\u00a0\u00bb, remarque l’institut de recherche. Il poursuit: \u00ab\u00a0l’e\u0301tiquette colle\u0301e sur le co\u0302te\u0301 du ruban adhe\u0301sif est en core\u0301en, mais l’e\u0301quipe ignore comment il est arrive\u0301 au large des co\u0302tes argentines et quel a\u0302ge il a\u00a0\u00bb. Curieux, les scientifiques ont emporte\u0301 la cassette et veulent maintenant e\u0301tudier si la faune locale inge\u0300re ce type de plastique.<\/p>\n
