Greetings,<\/p>\n
You are getting this email because you have at some point registered interest in the activities of the International Ocean Discovery Program (IODP). The NZ email list has been in abeyance but we are back in action because there is a lot happening over the next year and a half, with six local expeditions, 5 port calls, and a wide range of outreach activities. Expedition 371 sets off from Townsville in the next day or two, with the first ever NZ co-chief, Rupert Sutherland, ably assisted by fellow co-chief Jerry Dickens, three additional NZ scientists, Kristina Pascher, Wanda Stratford and Hugh Morgans (all from GNS), and the rest of the science party and crew. Follow the expedition here: http:\/\/joidesresolution.org\/expedition\/371\/<\/p>\n
We are now accepting ANZIC applications from scientists in our member institutions for scientific participation in three more JOIDES Resolution expeditions for late 2018 and early 2019. Opportunities exist for researchers (including graduate students) in all shipboard specialties \u2013 including but not limited to sedimentologists, micropaleontologists, paleomagnetists, inorganic\/organic
\ngeochemists, petrologists, petrophysicists, microbiologists, and borehole geophysicists.
\nSenior scientists are asked to ensure that this announcement is widely circulated to relevant groups in their institution.<\/p>\n

South Pacific Paleogene Climate Expedition (378): Heat Transport and Water Column Structure during an Extreme Warm Climate14 October \u2013 14 December 2018<\/p>\n
Expedition 378 will investigate the record of Cenozoic climate and oceanography through a drilling transect in the far southern Pacific Ocean. In particular, it will target sediments deposited during the very warm Late Paleocene and Early Eocene including the Paleocene-Eocene boundary, as well as the Eocene-Oligocene transition, to investigate how the Eocene earth maintained high global temperatures and high heat transport to the polar regions despite receiving near modern levels of solar energy input. Investigation of the recovered sediments also will constrain the subpolar Pacific climate, oceanographic structure, and biogeochemical cycling of much of the Cenozoic. These sediments will be used to characterize water masses, deep and shallow ocean temperature, latitudinal temperature gradients, the strength of upwelling, and the strength of the zonal winds to study both the atmospheric and oceanic climatic subsystems.<\/p>\n
The planned drilling strategy also will target a continuous sedimentary record at DSDP Site 277 by redrilling a previously spot-cored, classic Paleogene high latitude site. This will provide a crucial, continuous record of the shallow subantarctic South Pacific from the Paleocene to late Oligocene.<\/p>\n
This expedition in the South Pacific Ocean is critical to contribute to global reconstructions of the early Cenozoic since appropriate high-latitude records are unobtainable in the Northern Hemisphere of the Pacific. The drilling strategy optimizes the recovery of Paleogene carbonates buried under red clay sequences at present latitudes of 50\u00b0S to permit a full range of paleoceanographic proxy-based investigations.<\/p>\n
This expedition will also constrain (a) the Southern Ocean CCD history, (b) the record of Antarctic ice cover for the Paleogene through IRD characterization, (c) the development of the Antarctic Circumpolar Current, (d) the poleward extent of the low-productivity sub-tropical gyre, (e) the position of the polar front, (f) sea-surface temperatures and thermal gradients, (g) the breadth and intensity of the high-productivity zone associated with these oceanographic features, (h) the water masses formed in the sub-polar region, (i) the zonal winds and how they relate to oceanic surface circulation, and (j) document the changes in these systems as climate evolves from the warm early Eocene to the cold Antarctic-influence system of the Oligocene.<\/p>\n
Amundsen Sea West Antarctic Ice Sheet History Expedition (379) 18 January\u2013 20 March 2019<\/p>\n
The West Antarctic Ice Sheet (WAIS) is largely marine-based, highly sensitive to climatic and oceanographic changes, has had a dynamic history over the last several million years, and if completely melted, could result in a global sea-level rise of 3.3-4.3 m. Expedition 379 will obtain records from the continental shelf and rise of the Amundsen Sea to document WAIS dynamics in an area unaffected by other ice sheets as well as in an area that currently experiences the largest ice loss in Antarctica. The primary objectives include (a) reconstructing the Paleogene to Holocene glacial history of West Antarctica, (b) correlating the Amundsen Sea WAIS proximal records with global records of ice volume changes and
\nair\/seawater temperature proxy records, (c) constraining the relationship between incursions of warm water masses onto the continental shelf and the stability of marine-based ice sheet margins, and (d) reconstructing major WAIS advances onto the middle and outer shelf, including the first ice sheet expansion onto the continental shelf of the Amundsen Sea Embayment and its possible control by the uplift of Marie Byrd Land.<\/p>\n
Iceberg Alley Paleoceanography and South Falkland Slope Drift Expedition (382) 20 March \u2013 May 2019<\/p>\n
Expedition 382 aims to recover 600 m long Late Neogene sequences 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 icebergs 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 inter-hemispheric 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 of changes in the Southern Hemisphere westerlies to evaluate climate-dust couplings since the Pliocene, its potential role in iron fertilization and atmospheric CO2 drawdown during glacials. Expedition 382 will also core a sediment drift 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.<\/p>\n

ANZIC applications<\/p>\n
New Zealander-based scientists should request an application form from nzodp@gns.cri.nz. Australian-based scientists should visit www.iodp.org.au for a link to the application form.<\/p>\n
Applicants should bear in mind that their applications will be firstly reviewed and ranked by the ANZIC Science Committee and, if they pass that hurdle, by the expedition co-chief and IODP staff scientists. They need to convince both groups that they would be excellent in the role. Note that although the ANZIC Science Committee gives preference to early career researchers, non-tenured applicants and students must have a position at an Australian or New Zealand member institution for at least one year post-expedition and ideally more to enable them to carry out the necessary post cruise research.<\/p>\n
The following documentation should be included in the application:<\/p>\n
1. Completed Application Form<\/p>\n
2. Participation Plan (maximum of four pages) that should outline why you are interested in the expedition, how your skills suit the position applied for, what you would bring to the expedition, your initial post-cruise research plans (including publication plans), and a brief outline of what funding you might need beyond that covered by your institution.<\/p>\n
3. Curriculum Vitae including selected publications (maximum of two pages).<\/p>\n
4. Letter of support for non-tenured applicants from your supervisor or host institution. This should cover general support from the institution for the application, include an outline of the proffered post-cruise support and indication of when this support will end (at least one year post-cruise support is required).<\/p>\n
Financial support: For ANZIC scientists all travel costs, including those to some post-cruise meetings, would be covered by ANZIC. In addition, the ANZIC IODP Office may provide up to $40,000 for post-cruise activities (mainly analytical costs) if funding cannot be obtained in any other way. Applications for such funding can only be made after expeditions are completed and samples are in hand.<\/p>\n
Application deadlines: The deadline for scientists to submit applications to ANZIC for Expedition 378 is Monday, 15 September 2017, and for Expeditions 379 and 382 is Monday, 16 October 2017. The team in the NZ IODP Office at GNS Science are happy to provide advice on applications. Send applications to nzodp@gns.cri.nz.<\/p>\n
