The Observatory started AG (Absolute Gravimetry) measurements with FG5#206 in 1997. We present some studies carried on with the AG: 1) at Strasbourg: calibration of the SG, comparison with collocated GPS observations and with hydrological models. 2) at the Dumont d&#8217;Urville station, in Antarctica. Comparison of precise positioning observations, models and AG data leads to the conclusion of a vertical stability of the station. 3) in Africa, the present main target is hydrology and comparison with GRACE observations along a North-South profile. 4) we conclude with the results of international comparisons of AG (BIPM, S\u00e8vres and Walferdange) and present the AG database of BKG and BGI.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Martine AmalvictA Superconducting Gravimeter (SG) is continuously recording gravity changes at the St &hellip; <a href=\"https:\/\/www.eri.u-tokyo.ac.jp\/en\/intl-seminar\/3653\/\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;Absolute gravimetry and its applications: some studies&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[40],"tags":[],"class_list":["post-3653","post","type-post","status-publish","format-standard","hentry","category-intl-seminar"],"_links":{"self":[{"href":"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/3653"}],"collection":[{"href":"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=3653"}],"version-history":[{"count":0,"href":"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/3653\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=3653"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/categories?post=3653"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/tags?post=3653"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
