This will (a) constrain iceberg flux during key times of AIS evolution since the Middle Miocene glacial intensification of the East Antarctic Ice Sheet, (b) provide material to determine regional sources of AIS mass loss, address interhemispheric phasing of ice-sheet and climate events, and the relation of AIS variability to sea level, (c) provide information on Drake Passage throughflow, meridional overturning in the Southern Ocean, water-mass changes, CO<sub>2<\/sub> transfer via wind-induced upwelling, sea-ice variability, bottom water outflow from the Weddell Sea, Antarctic weathering inputs, and changes in oceanic and atmospheric fronts in the vicinity of the ACC, and (d) provide dust proxy records to reconstruct changes in the Southern Hemisphere westerlies to evaluate climate-dust coupling since the Pliocene, its potential role in iron fertilization and atmospheric CO<sub>2<\/sub> drawdown during glacials. Expedition 382 will also core a sediment drift on the Falkland slope to obtain subantarctic multi-proxy intermediate water depth records of millennial to orbital scale variability in the ocean, atmosphere, nutrients, productivity and ice-sheet dynamics in the SW Atlantic through at least the last 1 Ma.\u00a0The deadline to apply is <strong>October 15, 2017<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Expedition 382 aims to recover 600 m long Late Neogene sedimentary sequences from the Scotia Sea to reconstruct past variability in Antarctic Ice Sheet (AIS) mass loss, oceanic and atmospheric circulation and to provide the first spatially integrated record of variability in iceberg flux from Iceberg Alley, where a substantial number of Antarctic icebergs exit&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[31,46],"tags":[],"organization":[90],"_links":{"self":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/posts\/11587"}],"collection":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/comments?post=11587"}],"version-history":[{"count":1,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/posts\/11587\/revisions"}],"predecessor-version":[{"id":11588,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/posts\/11587\/revisions\/11588"}],"wp:attachment":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/media?parent=11587"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/categories?post=11587"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/tags?post=11587"},{"taxonomy":"organization","embeddable":true,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/organization?post=11587"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
