microgravim\u00e9trie ? La microgravim\u00e9trie repose sur la d\u00e9tection de micro-variations du champ gravitationnel terrestre, souvent de l\u2019ordre de quelques milliGals (mGal). La pr\u00e9cision de la mesure et le traitement rigoureux des donn\u00e9es sont donc essentiels pour d\u00e9tecter des cavit\u00e9s [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":72,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-191","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/versionbeta.ovh\/gravimep\/wp-json\/wp\/v2\/pages\/191","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/versionbeta.ovh\/gravimep\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/versionbeta.ovh\/gravimep\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/versionbeta.ovh\/gravimep\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/versionbeta.ovh\/gravimep\/wp-json\/wp\/v2\/comments?post=191"}],"version-history":[{"count":13,"href":"https:\/\/versionbeta.ovh\/gravimep\/wp-json\/wp\/v2\/pages\/191\/revisions"}],"predecessor-version":[{"id":512,"href":"https:\/\/versionbeta.ovh\/gravimep\/wp-json\/wp\/v2\/pages\/191\/revisions\/512"}],"up":[{"embeddable":true,"href":"https:\/\/versionbeta.ovh\/gravimep\/wp-json\/wp\/v2\/pages\/72"}],"wp:attachment":[{"href":"https:\/\/versionbeta.ovh\/gravimep\/wp-json\/wp\/v2\/media?parent=191"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
