IODP EXPEDITION 396: Norwegian Continental Margin Magmatism (6 August - 6 October 2021)
DEADLINE 11 October 2020

Background and Objectives.
Mid-Norwegian Continental Margin Magmatism Expedition 396 is a scientific ocean drilling project that seeks to understand the nature, cause and climate implications of excess magmatism during the northeast Atlantic continental breakup. Competing geodynamic end-member hypotheses exist for the formation of this excess magmatism, but their relative importance remains unresolved: (1) elevated mantle potential temperatures associated with mantle plume processes, (2) enhanced material flux through the melt window during rifting caused by small-scale convection at the base of the lithosphere, and (3) mantle source heterogeneity that may contribute to anomalously high melt production during continental breakup. Voluminous magmatism also coincides with the global greenhouse climate in the early Paleogene and has been proposed as a driver of both short-term (Paleocene-Eocene Thermal Maximum) and long-term (early Eocene Climate Optimum) global warming. However, the timing of the magmatism is not sufficiently constrained. Improved constraints on melting conditions, timing of magmatism, magmatic fluxes in time and space, eruption environment, sedimentary proxy data, and relative timing of climate events are required to resolve these linked controversies. Expedition 396 is based on IODP Proposals 944-Full2 and 944-Add2 and will target volcanic and sedimentary sequences at nine primary sites along and across the mid-Norwegian margin.

Expertise sought
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 most shipboard specialties, including but not limited to sedimentologists, volcanologists, petrologists, igneous geochemists, inorganic and organic geochemists, micropaleontologists, paleomagnetists, physical properties specialists, and borehole geophysicists. Good working knowledge of the English language is required.
