<span style="color:black">Reykjanes Mantle Convection Expedition 395 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.</span><o:p></o:p></p>

<span style="color:black">Expedition 395 is based on IODP Proposal 892-Full2 (Mantle Dynamics, Paleoceanography and Climate Evolution in the North Atlantic Ocean) and 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.</span><o:p></o:p></p>
