Three-dimensional modeling of outcrop-to-outcrop hydrothermal circulation on the eastern flank of the Juan de Fuca Ridge
We present three-dimensional simulations of coupled fluid and heat transport in the ocean crust, to explore patterns and controls on ridge-flank hydrothermal circulation on the eastern flank of the Juan de Fuca Ridge. Field studies have shown that there is large-scale fluid flow in the volcanic ocean crust in this region, including local convection and circulation between two basement outcrops ...
متن کاملHydrothermal circulation within topographically rough basaltic basement on the Juan de Fuca Ridge flank
[1] We use coupled heat and mass transport models to investigate the basement permeability distribution and hydrothermal circulation patterns in an area with large basement relief below flat seafloor on the eastern flank of the Juan de Fuca Ridge. If heat transport around Ocean Drilling Program Sites 1026 and 1027 were purely conductive, the top of basement at Site 1027 (below 600 m of sediment...
متن کاملDissolved inorganic carbon isotopic composition of low-temperature axial and ridge-flank hydrothermal fluids of the Juan de Fuca Ridge
We analyzed stable carbon (δC) and radiocarbon (ΔC) isotopes of ocean crustal fluid samples from two low-temperature environments on and near the Juan de Fuca Ridge (JDFR), a seafloor spreading center in the northeastern Pacific Ocean. Themajor goals of this work were to resolve relative dissolved inorganic carbon (DIC) sources and removal processes, and characterize the isotopic signatures of ...
متن کاملInfluence of Igneous Basement on Deep Sediment Microbial Diversity on the Eastern Juan de Fuca Ridge Flank
Microbial communities living in deeply buried sediment may be adapted to long-term energy limitation as they are removed from new detrital energy inputs for thousands to millions of years. However, sediment layers near the underlying oceanic crust may receive inputs from below that influence microbial community structure and/or activity. As part of the Census of Deep Life, we used 16S rRNA gene...
