This kind of reoccurring drainage under Thwaites has never before been recorded. Scientists estimate that the rate of drainage peaked at about 500 cubic metres a second \u2013 possibly the largest outflow of meltwater ever reported from subglacial lakes in this region.<\/p>\n<p>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/www.esa.int\/ESA_Multimedia\/Videos\/2020\/12\/Ebb_and_flow_of_lakes_deep_below_Thwaites_glacier\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Ebb and flow of lakes deep below Thwaites glacier<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: ESA Top Multimedia&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A paper\u00a0published in Geophysical Research Letters\u00a0describes how a decade of radar altimetry observation have been used to reveal a network of four subglacial lakes, under the Thwaites glacier in Antarctica.&hellip; <\/p>\n","protected":false},"author":1,"featured_media":675830,"comment_status":"false","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[],"class_list":["post-675829","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-multimedia"],"_links":{"self":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/posts\/675829","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=675829"}],"version-history":[{"count":0,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/posts\/675829\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=\/wp\/v2\/media\/675830"}],"wp:attachment":[{"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=675829"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=675829"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/spaceweekly.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=675829"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
