The experiments were designed to examine hydrological and biological processes in basaltic ocean crust. Major issues to be addressed include overall permeability, the magnitudes, velocity and directions of fluid, solute,and heat transport,constraints on the fluid storage properties of crust, determining how fluid reservoirs respond to seismic perturbations, and investigating the variability, diversity, and metabolism of resident microbial populations. This project will recover sensors and samplers in the instrumented boreholes(CORKs),access data and samples, collect biological incubators placed at depth within the boreholes, and seal the CORKs. All of these activities are needed for the completion of the JDFR experiments<\/p>\n<p>Once the data and samples are retrieved, the PI&#8217;s will develop new numerical models for the hydrology (permeability, thickness and extent of permeable zones, connectivity, direction of flow, and anisotropy) of ocean crust based on the results of flow tests. T sensors will enable thermal structure to be determined in conjunction with flow parameters. DNA will be analyzed via 16S ribosomal RNA (rRNA) genes as well as select full-length Sanger-style sequencing and gene fingerprinting techniques. The PI&#8217;s will look at diversity, shared species, emergence and disappearance of groups. Metagenomic work will be done on some samples.<\/p>\n","protected":false},"template":"","_links":{"self":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/data_projects\/10072"}],"collection":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/data_projects"}],"about":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/types\/data_project"}],"wp:attachment":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/media?parent=10072"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
