Expedition 397: Iberian Margin Paleoclimate
6 October to 6 December 2022
The Iberian Margin has rapidly accumulating sediment that contains a high-fidelity late Pleistocene record of millennial climate variability (MCV). Sir Nickolas Shackleton demonstrated that piston cores from this region can be correlated precisely to polar ice cores from both hemispheres. Moreover, the narrow continental shelf off Portugal results in the rapid delivery of terrestrial material to the deep-sea environment, thereby allowing correlation of marine and ice core records to European terrestrial sequences. Few places exist in the world where such detailed marine-ice-terrestrial linkages are possible. The continuity, high sedimentation rates, and fidelity of climate signals preserved in sediments make this region a prime target for ocean drilling. During IODP Expedition 339, Site U1385 was drilled and recovered a complete record of hemipelagic sedimentation for the last 1.43 Ma with a mean sedimentation rate of 11 cm/kyr. IODP Expedition 397 will extend this remarkable sediment archive through the Pliocene and recover a complete depth transect of five sites that will provide a complete suite of downhole records with which to study past variability in the major subsurface water masses of the North Atlantic.
Expedition 398: Hellenic Arc Volcanic Field
6 December 2022 to 5 February 2023
The Hellenic Arc Christiana-Santorini-Kolumbo (CSK) volcanic field, which includes Santorini caldera and its Late Bronze Age eruption, provides a unique opportunity to address how subduction-related volcanism impacts life. Better understanding of island-arc volcanism requires study of the processes that drive such volcanism, and how the volcanoes interact with the marine environment. What are the links between crustal tectonics, volcanic activity, and magma genesis? What are the dynamics and impacts of submarine explosive volcanism and caldera-forming eruptions? What are the reactions of marine ecosystems to volcanic eruptions? The rift basins around the CSK field, as well as Santorini caldera, contain volcano-sedimentary fills up to several hundreds of meters thick. We propose to drill six sites, four in the rifts basins and two in Santorini caldera. Deep drilling is essential to characterize and interpret the depositional packages visible on seismic images, to chemically correlate primary volcaniclastic layers in the rift fills with their source volcanoes, to fill in gaps in onland volcanic records, to provide a precise chronostratigraphic framework for rift tectonic and sedimentary histories, and to characterize the subsurface microbial life.

Application deadline: 1 November 2021
WHO SHOULD APPLY: We encourage applications from all qualified scientists. The JOIDES Resolution Science Operator (JRSO) is committed to a policy of broad participation and inclusion, and to providing a safe, productive, and welcoming environment for all program participants. Opportunities exist for researchers (including graduate students) in all shipboard specialties, including micropaleontologists, sedimentologists, volcanologists, petrologists, igneous geochemists, inorganic and organic geochemists, paleomagnetists, microbiologists, physical properties specialists, and borehole geophysicists. Good working knowledge of the English language is required.
IMPORTANT INFORMATION BEFORE YOU APPLY
Australian applicants : All applicants must have their sign off by their institution DVC-Research or other appropriate institutional level, that their institution approves their travel and will insure them for that travel to and from the port of departure and arrival.It is agreed that Institutions will cover any additional cost related to delays to a return or additional quarantine costs.ANZIC will cover: flights and ground transport/incidentals to/from the ship, any pre-departure mandatory quarantine period (up to ~A$3000 for Australian members (accommodation and hotel meals); the cost of a pre-flight COVID test (if required, and as outlined in the IODP COVID policy) will continue to support the selected expeditioner with coverage of required pre-cruise medicals (Aust only; NZ to detail) up to $40K (over 2 years, Australian members) is available to conduct the expected research related to the international expedition. Visa expenses will be covered by ANZIC but organised by the expeditioner in consultation with the JRSO if an ANZIC candidate is selected to sail. Without this sign off an applicant will not be assessed by ANZIC for the expeditioner role advertised and, therefore, will not be forwarded to the JRSO for consideration as an expeditioner.
New Zealand Applicants: Please contact Stuart Henrys (email@example.com) prior to submitting your application to inquire about the prerequisites that will apply.
