Pour y re\u0301pondre, (re)de\u0301couvrez ci-dessous un extrait du livre livre Abysses, l’ultime frontie\u0300re (e\u0301ditions Alisio) du journaliste Olivier Lascar, re\u0301dacteur en chef du po\u0302le nume\u0301rique de Sciences et Avenir – La Recherche. D’autres extraits sont a\u0300 de\u0301couvrir dans notre pre\u0301ce\u0301dent article \u00ab\u00a0Abysses, l’ultime frontie\u0300re, une plonge\u0301e e\u0301clairante dans les grands fonds marins<\/b>\u00ab\u00a0, issu du mensuel de Sciences et Avenir – La Recherche n\u00b0920, date\u0301 octobre 2023.<\/p>\n

Les abysses, en dessous de 1000 me\u0300tres de profondeur<\/b>
\n
\n\u2018\u2018[…] la plupart des spe\u0301cialistes parlent d’abysses pour ce qui est en dec\u0327a\u0300 de 1000 me\u0300tres de profondeur. Et cela repre\u0301sente une part conside\u0301rable de notre plane\u0300te, dont la surface est recouverte a\u0300 71 % par les oce\u0301ans. Dans une e\u0301tude publie\u0301e par la Fondation de la mer, il est ainsi pre\u0301cise\u0301 que 88 % du plancher oce\u0301anique est situe\u0301 au-dela\u0300 de 1000 me\u0300tres de profondeur.<\/p>\n

On connai\u0302t mieux la surface de la Lune que le fond des oce\u0301ans<\/b><\/p>\n

[…] Immenses par leur superficie, ces grands fonds marins demeurent extraordinairement me\u0301connus, puisque moins de 20 % sont cartographie\u0301s et moins de 5 % explore\u0301s. […] Quid des animaux qui y vivent ? Des ressources mine\u0301rales ? A\u0300 force, la formule fait cliche\u0301, pourtant c’est vrai: on connai\u0302t mieux la surface de la Lune que le fond des oce\u0301ans. A\u0300 l’exploration scientifique de lever le voile sur ces questions pour percer d’un peu de lumie\u0300re cette obscurite\u0301.<\/p>\n
