This second branch appears to be highly seasonal, and carries the largest heat and volume in autumn and winter.<br \/>\nA third, smaller branch, follows the outer perimeter of the Yermak Plateau and then turns eastward, flowing as a wide, slow and semi-deep current along the outer, deep part of the continental slope.<\/p>\n<p>Together, this large current system carries an enormous amount of heat and salt into the region \u2013 of similar magnitude as the Barents Sea Branch but with higher temperature when it enters the Arctic Ocean proper.

Since 2018 the project has also received funding from the Research Council of Norway through the SIOS-InfraNor project. International A-TWAIN collaborators include IOPAS (Poland), SAMS (UK), Sorbonne Universit\u00e9 (FR), and WHOI (USA).<\/p>\n<p>The first moorings were deployed in September 2012, during a cruise where a large survey of hydrography was also undertaken. In 2013 the moorings were recovered, and a new spatial mapping of water masses was done. Moorings were deployed again from 2013 to 2015, and redeployed again from 2015 to 2017 and from 2017 to 2019. We plan to continue with at least bi-annual mooring service and hydrography cruises for the foreseeable future.<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-6wk5zi-3a40f2c91fe403edff27d6882297472c\">\n.flex_column.av-6wk5zi-3a40f2c91fe403edff27d6882297472c{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-6wk5zi-3a40f2c91fe403edff27d6882297472c av_one_third  avia-builder-el-10  el_after_av_two_third  el_before_av_one_full  flex_column_div av-zero-column-padding  column-top-margin'     ><section  class='av_textblock_section av-5hcgj2-b6215a95dea86f07e21f68393507328b '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><div id=\"attachment_5656\" style=\"width: 460px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_p3.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-5656\" class=\"wp-image-5656 size-full\" src=\"https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_p3.jpg\" alt=\"A woman on a ship working on scientific equipment\" width=\"450\" height=\"299\" srcset=\"https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_p3.jpg 450w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_p3-300x199.jpg 300w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" \/><\/a><p id=\"caption-attachment-5656\" class=\"wp-caption-text\">Foto: Amy Cooper \/ Woods Hole Oceanographic Institute<\/p><\/div>\n<\/div><\/section><\/div><\/p>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-3x72gu-8df1507890f8f63ec297be9478a30ace\">\n.flex_column.av-3x72gu-8df1507890f8f63ec297be9478a30ace{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-3x72gu-8df1507890f8f63ec297be9478a30ace av_one_full  avia-builder-el-12  el_after_av_one_third  avia-builder-el-last  first flex_column_div av-zero-column-padding  column-top-margin'     ><section  class='av_textblock_section av-2mjr7y-85e421c235723e906c877caa86ec802f '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><div id=\"attachment_5658\" style=\"width: 910px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_group.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-5658\" class=\"wp-image-5658 size-full\" src=\"https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_group.jpg\" alt=\"Group photo\" width=\"900\" height=\"220\" srcset=\"https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_group.jpg 900w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_group-450x110.jpg 450w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_group-300x73.jpg 300w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_group-768x188.jpg 768w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/02\/atwain_group-705x172.jpg 705w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/a><p id=\"caption-attachment-5658\" class=\"wp-caption-text\">A-Twain team<\/p><\/div>\n<\/div><\/section><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":20,"featured_media":38345,"parent":5377,"menu_order":1,"comment_status":"closed","ping_status":"closed","template":"page-projectdetail.php","meta":{"_acf_changed":false,"footnotes":""},"tags":[],"emne":[],"class_list":["post-22200","page","type-page","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/pages\/22200","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/comments?post=22200"}],"version-history":[{"count":5,"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/pages\/22200\/revisions"}],"predecessor-version":[{"id":50400,"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/pages\/22200\/revisions\/50400"}],"up":[{"embeddable":true,"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/pages\/5377"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/media\/38345"}],"wp:attachment":[{"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/media?parent=22200"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/tags?post=22200"},{"taxonomy":"emne","embeddable":true,"href":"https:\/\/npolar.no\/en\/wp-json\/wp\/v2\/emne?post=22200"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
