IODP expedition 395 applications and webinar

Expedition 395 Reykjanes Mantle Convection & Climate

Informational Webinar The International Ocean Discovery Program (IODP) is now accepting applications for scientific participants on  aboard the JOIDES Resolution. Opportunities exist for researchers (including graduate students) in all shipboard specialties, including but not limited to sedimentologists, petrologists, micropaleontologists, paleomagnetists, petrophysicists, borehole geophysicists, igneous geochemists, inorganic and organic geochemists. To learn more about the scientific objectives of Expedition 395, life at sea, and how to apply to sail, please join us for a web-based seminar on Thursday, March 26, 2020 at 12:00 pm Eastern Daylight Time.

 will investigate mantle upwelling beneath Iceland, which supports the regional bathymetry and has led to changes in the height of oceanic gateways that control the strength of deep-water flow over geologic timescales. This drilling program contains three objectives: (1) to test contrasting hypotheses for the formation of V-shaped ridges that are the result of interaction between the Mid-Atlantic Ridge and the Iceland plume; (2) to understand temporal changes in ocean circulation and explore connections with plume activity; and (3) to reconstruct the evolving chemistry of hydrothermal fluids with increasing crustal age, varying sediment thickness, and crustal architecture.

The expedition will target the sediments and 130 m of igneous basement along with downhole logging at five sites east of Reykjanes Ridge. Four sites intersect V-shaped ridges/troughs pairs, one of which coincides with Bjorn Drift. The fifth site is located over 32.4 Ma oceanic crust devoid of V-shaped features, chosen to intersect Oligocene-Miocene sediments of Gardar Drift. Millennial-scale paleoclimate records are contained within rapidly accumulated sediments of contourite drifts in this region. The accumulation rate of the sediments is a proxy for current strength, and the sediments also provide constraints for climatic events including Pliocene warmth, the onset of Northern Hemisphere Glaciation, and abrupt Late Pleistocene climate change. Major, trace and isotope geochemistry of basalts will allow us to observe spatial and temporal variations in mantle melting processes. This combined approach will explore relationships between deep Earth processes, ocean circulation, and climate. The expedition will occur from 26 June to 26 August 2020.
