CALL: Expedition 382 (Iceberg Alley Paleoceanography and South Falkland Slope Drift)

ECORD is seeking scientists to participate in JOIDES Resolution Expedition 382: Iceberg Alley Paleoceanography and South Falkland Slope Drift (20 March - ~20 May 2019). Opportunities exist for researchers (including graduate students) in all shipboard specialties - including but not limited to sedimentologists, micro paleontologists, paleomagnetists, inorganic/organic geochemists, petrologists, petrophysicists, microbiologists, and borehole geophysicists.

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 into the warmer Antarctic Circumpolar Current (ACC).

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, CO2 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 CO2 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.

Please see the attached CALL and JOIDES Resolution webpage for more information. The deadline to apply is 15 October 2017.

Canadian-based applicants must be NSERC-funded active researchers, or students/fellows working under the direct supervision of such researchers.  Candidates may request support and feedback on their application from the CCOD Coordinator.  All candidates must send their application to iodpcanada@gmail.com at least 1 week before the deadline (before submission to ECORD) for approval by the CCOD Executive Committee.  

Please note that the way in which Canada participates in IODP has recently changed.  Funding for our membership in ECORD is now solely driven by individual researchers and their respective universities, and is guaranteed until December 31, 2017.  Canadian selection for expeditions is contingent upon Canada maintaining active membership.  All applicants should thus contact us to see how they can contribute.
