One of the causes of this flexing is the periodic filling and draining of meltwater lakes on top of, within, and beneath the ice. In several new studies, scientists have used NASA\u2019s Ice, Cloud, and land Elevation Satellite 2 (ICESat-2) to improve our view of this icy plumbing system.<\/p>\n<p>At its thickest points, Antarctic ice can be hundreds to thousands of meters thick; the rising and falling caused by meltwater lakes tends to be subtle and localized. But with ICESat-2, scientists can map even small ice elevation changes with a precision down to just a few centimeters.<\/p>\n<p>\u201cThese are processes going on under Antarctica that we wouldn\u2019t have a clue about if we didn\u2019t have satellite data,\u201d said Helen Amanda Fricker, a glaciologist at Scripps Institution of Oceanography. \u201cWe\u2019ve been struggling with getting good predictions about the future of Antarctica, and instruments like ICESat-2 are helping us observe at the process scale.\u201d<\/p>\n<p>Source: <a href=\"https:\/\/www.enn.com\/articles\/68224-space-lasers-map-meltwater-lakes\">ENN<\/a><\/p>\n<p>&nbsp;<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Satellites can \u201csee\u201d Antarctica\u2019s surface deform as basins fill and empty on, within, and under the ice.\u00a0 Despite the enormous weight and thickness of Antarctica\u2019s&#8230;<\/p>\n","protected":false},"author":4,"featured_media":5081,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_FSMCFIC_featured_image_caption":"","_FSMCFIC_featured_image_nocaption":null,"_FSMCFIC_featured_image_hide":null,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false},"categories":[32,77],"tags":[988,13986,12960,855,5252],"class_list":["post-53357","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-csr-news-en","category-weeks-highlights","tag-lake","tag-laser","tag-map","tag-meltwater","tag-space","wpcat-32-id","wpcat-77-id"],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/vastuullisuusuutiset.fi\/wp-content\/uploads\/2020\/03\/Antarctic_sea.jpg?fit=150%2C150&ssl=1","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/posts\/53357","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/comments?post=53357"}],"version-history":[{"count":4,"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/posts\/53357\/revisions"}],"predecessor-version":[{"id":53472,"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/posts\/53357\/revisions\/53472"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/media\/5081"}],"wp:attachment":[{"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/media?parent=53357"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/categories?post=53357"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/fi\/wp-json\/wp\/v2\/tags?post=53357"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
