Call for application for JOIDES Resolution Expeditions 390 and 393
Deadline for scientists to apply: ~15 October 2021
Expedition 390: South Atlantic Transect 1 (7 April to 7 June 2022)
Expedition 393: South Atlantic Transect 2 (7 June to 7 August 2022)
South Atlantic Transect Expeditions 390 and 393 (IODP Proposals 853-Full2 and 853-Add) are a multidisciplinary and joint scientific drilling project that aims to recover complete sedimentary sections and ~200 m of oceanic crust at sites along a crustal age transect at ~31°S across the South Atlantic to (1) investigate the history of the low-temperature hydrothermal interactions between the aging ocean crust and the evolving South Atlantic Ocean; (2) quantify past hydrothermal contributions to global geochemical cycles; (3) investigate the sediment and basement-hosted microbial community in the low energy South Atlantic Gyre subseafloor biosphere; and (4) investigate the response of subtropical biota and ocean circulation in the core of the global conveyor belt and the subtropical gyre in the South Atlantic Ocean as a result of the opening of the Drake Passage.
The South Atlantic Transect expeditions will target six primary sites on 7, 15, 31, 49, and 61 Ma ocean crust. The proposed transect, which follows a Mid-Atlantic Ridge crustal flow-line, will fill critical gaps in our sampling of intact in-situ ocean crust with regards to crustal age, spreading rate, and sediment thickness. The transect traverses the previously unexplored sediment- and basalt-hosted deep biosphere beneath the South Atlantic gyre, samples of which are essential to refine global biomass estimates and investigate microbial ecosystems’ responses to variable conditions in a low energy gyre and aging ocean crust. The transect is located near World Ocean Circulation Experiment (WOCE) line A10, providing present-day carbonate chemistry and deep-water mass properties across the western South Atlantic for comparison to records of key Cenozoic intervals of elevated atmospheric CO2 and rapid climate change. Reconstruction of the history of the deep western boundary current and deep-water formation in the Atlantic basins will yield crucial data to test hypotheses regarding the role of evolving thermohaline circulation patterns in climate change, and the effects of tectonic gateways and climate on ocean acidification.

Who Should Apply: We encourage applications from all qualified scientists (including graduate students) in (1) microbiology and sedimentology for Expedition 390, and (2) microbiology for Expedition 393.Microbiology candidates with experience using sediment oxygen sensors or handling hard rock microbiology samples are encouraged. The JOIDES Resolution Science Operator (JRSO) is committed to a policy of broad participation and inclusion, and to providing a safe and welcoming environment for all participants. Good working knowledge of the English language is required.COVID-19 Protocol: The JRSO has created a protocol to safely operate during the COVID-19 pandemic. If pandemic conditions have not improved by early-mid 2022, one or both expeditions may need to sail with a reduced shipboard contingent. However, all participants will maintain their designation as science party members regardless of whether they sail or not, and will have equal access to all expedition data and core materials. The protocol is available here: http://iodp.tamu.edu/…/JR_COVID-Mitigation-Protocols.pdf.
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.
