Pour aborder cette probl\u00e9matique, nous allons combiner (1) les reconstitutions des conditions de la M\u00e9diterran\u00e9e durant des \u00e9v\u00e9nements de perturbation de forte amplitude \u00e0 partir de plusieurs traceurs dont la compositions isotopique du Nd analys\u00e9s sur les phases authig\u00e9niques avec (2) des simulations num\u00e9riques obtenues avec un mod\u00e8le r\u00e9gional \u00e0 haute r\u00e9solution spatiale (1\/8\u00ba) int\u00e9grant l\u2019\u00e9volution de certains traceurs de la circulation. Nous allons nous focaliser sur l\u2019analyse des couches s\u00e9dimentaires riches en mati\u00e8res organiques, appel\u00e9es \u00ab sapropels \u00bb, d\u00e9pos\u00e9es lors de p\u00e9riodes de circulation stagnante en M\u00e9diterran\u00e9e. Nous allons nous int\u00e9resser plus particuli\u00e8rement au sapropel S5 form\u00e9 au cours du dernier interglaciaire, une p\u00e9riode chaude pouvant \u00eatre compar\u00e9e au r\u00e9chauffement simul\u00e9 dans un avenir prochaine. Nous appliquerons une batterie de traceurs compl\u00e9mentaires (g\u00e9ochimie et micropal\u00e9ontologie, y compris de nouveaux traceurs potentiels) \u00e0 une s\u00e9rie de carottes de s\u00e9diment localis\u00e9es le long d\u2019un transect zonal afin de proposer une reconstitution robuste. Le projet MedSens repose sur un consortium de partenaires aux comp\u00e9tences compl\u00e9mentaires : reconstitution \u00e0 partir de l\u2019analyse de traceurs (CEREGE\/GEOAZUR et GEOPS) et mod\u00e9lisation num\u00e9rique (LSCE\/LMD).<\/p>\n<\/div><div class=\"fusion-image-element \" style=\"text-align:center;--awb-caption-title-font-family:var(--h2_typography-font-family);--awb-caption-title-font-weight:var(--h2_typography-font-weight);--awb-caption-title-font-style:var(--h2_typography-font-style);--awb-caption-title-size:var(--h2_typography-font-size);--awb-caption-title-transform:var(--h2_typography-text-transform);--awb-caption-title-line-height:var(--h2_typography-line-height);--awb-caption-title-letter-spacing:var(--h2_typography-letter-spacing);\"><span class=\" fusion-imageframe imageframe-none imageframe-1 hover-type-none\"><img decoding=\"async\" width=\"605\" height=\"162\" title=\"medsens\" src=\"https:\/\/geops.geol.u-psud.fr\/pds\/wp-content\/uploads\/sites\/3\/2025\/09\/medsens.jpg\" alt class=\"img-responsive wp-image-165\" srcset=\"https:\/\/geops.geol.u-psud.fr\/pds\/wp-content\/uploads\/sites\/3\/2025\/09\/medsens-200x54.jpg 200w, https:\/\/geops.geol.u-psud.fr\/pds\/wp-content\/uploads\/sites\/3\/2025\/09\/medsens-400x107.jpg 400w, https:\/\/geops.geol.u-psud.fr\/pds\/wp-content\/uploads\/sites\/3\/2025\/09\/medsens-600x161.jpg 600w, https:\/\/geops.geol.u-psud.fr\/pds\/wp-content\/uploads\/sites\/3\/2025\/09\/medsens.jpg 605w\" sizes=\"(max-width: 640px) 100vw, 605px\" \/><\/span><\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-164","post","type-post","status-publish","format-standard","hentry","category-oceanique"],"_links":{"self":[{"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/posts\/164","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/comments?post=164"}],"version-history":[{"count":1,"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/posts\/164\/revisions"}],"predecessor-version":[{"id":166,"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/posts\/164\/revisions\/166"}],"wp:attachment":[{"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/media?parent=164"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/categories?post=164"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/geops.geol.u-psud.fr\/pds\/wp-json\/wp\/v2\/tags?post=164"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
