CALL: Expedition 385: Guaymas Basin Tectonics and Biosphere

ECORD is seeking scientists to participate in JOIDES Resolution Expedition 385: Guaymas Basin Tectonics and Biosphere (19 September to 19 November 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 385 will core and log a series of sites in the Guaymas Basin to investigate the relationships between tectonics, magmatism, sedimentation, carbon cycling, and microbial activity. The Guaymas Basin in the Gulf of California is a young, marginal rift basin characterized by active seafloor spreading and rapid deposition of organic-rich sediments from highly productive overlying waters. The active formation of oceanic crust combined with a thick sedimentary overburden has given rise to a dynamic environment, where strongly connected physical, chemical, and biological processes govern the cycling of sedimentary carbon. Its fate upon deposition depends on the relative efficiencies of interrelating microbial and chemical processes, leading either to sequestration or release of carbon. Expedition 385 aims to illuminate the interaction between these processes and its ultimate consequences for carbon cycling, which will help understand similar settings in marginal seas throughout the world.

The expedition's primary objectives are to:

  1. Explore the physical and chemical gradients along active and extinct fluid pathways associated with sill emplacement
  2. Investigate subsurface microbial communities that are sustained by alteration products, in order to determine how efficiently they capture carbon-bearing alteration products
  3. Advance our understanding of the conditions that limit life in the deep biosphere

Please see the attached CALL and JOIDES Resolution webpage for more information. The deadline to apply is 15 April 2018. 

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 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 currently driven by individual researchers and their respective universities. Canadian selection for expeditions is contingent upon Canada maintaining active membership.  All applicants should thus contact us to see how they can contribute.
