APPLICATION DEADLINE: 1 December 2022

Applications are invited from scientists in IODP-participating countries to join the Science Party for IODP Expedition 402: Tyrrhenian Continent-Ocean Transition, taking place from 9 February – 8 April 2024 onboard JOIDES Resolution. View the Expedition 402 webpage

Background

Expedition 402 will investigate the temporal and spatial evolution of a continent-ocean transition (COT), from breakup to robust magmatism and subsequent mantle exhumation with closely time-related magmatism. The Tyrrhenian Basin is the youngest basin of the western Mediterranean Sea, forming in the late Miocene to recent by continental extension related to rollback of the ESE-SE migrating Apennine subduction system. Its basement has been dredged along bathymetric highs and the stratigraphy is reasonably well known from three prior drilling expeditions (DSDP Legs 13 and 42 and ODP Leg 107). 

Recent geophysical and seismic data support the presence of magmatic rocks formed during the early COT phase, and of subsequently exhumed mantle. The youth of the basin results in a modest sediment cover which facilitates sampling of the peridotitic and magmatic basement across the conjugated COT of the basin with unprecedented spatial resolution. Expedition 402 will target six sites along a west-east and north-south transect, with drill cores recovering peridotitic basement at each site, followed by downhole logging.

Scientific objectives

The recovered material and data from Expedition 402 will address five primary scientific objectives:

  1. Determine the kinematics and geometry in space and time of the extensional deformation in the basin.
  2. Establish the timing and origin of the associated magmatism.
  3. Establish the rheology, deformation patterns and timing of mantle exhumation.
  4. Determine the compositional evolution and heterogeneity of the mantle source.
  5. Test current models of continental lithosphere rifting and of COT formation.

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, petrologists, igneous geochemists, inorganic and organic geochemists, microbiologists, paleomagnetists, physical properties specialists, and borehole geophysicists. Good working knowledge of the English language is required.

How to apply

Applications for participation must be submitted to the appropriate IODP Program Member Office. In your application, please specify if you are interested in participating offshore-onshore or onshore-only. Please note that there is no option to participate offshore-only. 

Applications should reach the appropriate Program Member Office no later than Thursday 1 December 2022
