Science party

To complete the onboard sampling, analyses, and logging as described above, Expedition 337 will invite a shipboard scientific party that consists of 25–26 scientists, including the two Co-Chief Scientists, sedimentologists, organic and inorganic geochemists, (geo-)microbiologists, physical property specialists, micropaleontologists, and structural geologists. In addition to typical requirements in each of these specialties, particular needs in Expedition 337 include, but are not limited to, the following specific expertise:

• Petroleum geologists and sedimentologists with strong interest in biogeochemical diagenetic processes on the deeply buried coalbed and/or shore-based CO₂ sequestration into a subseafloor hydrocarbon system;

• Biogeochemists and geochemists with experience/background in pore water analysis of biologically relevant chemical species, in rate measurements using radioactive tracers, in hydrogen and hydrocarbon gas analysis, in mud gas monitoring including isotope analysis, in geochemical modeling of transport and reaction of dissolved constituents, and in quantitative and compositional analysis of dissolved organic matter;

• Microbial ecologists and molecular biologists with experience in shipboard cell enumeration using flow cytometry and/or image-based microscopic analysis, in shipboard anaerobic and aseptic sampling of sediment or rock, in shore-based anaerobic cultivation techniques using high-pressure chamber and/or flow-through reactor systems, in shipboard contamination assessment using tracers such as fluorescent microbeads and/or PFT, in DNA/RNA-based functional gene analyses, in RNA-based molecular analyses of community structure and/or gene expression, and/or in single cell biology and (meta)genomics;

• Physical property specialists with experience/background in measurement of porosity, permeability, and determination of fluid migration in cored materials, sidewall minicores, and wireline logging data and/or in reactions between liquid and supercritical CO₂-containing fluids and sedimentary rock/minerals;

• Biostratigraphers with experience in micro- and nannofossil age determination in the northeastern Pacific and terrestrial/coastal deposits and/or in isotopic analyses using beryllium, rhenium-osmium, and iodine for depositional and fluid age; and

• Logging specialists with experience in in situ geophysical and geochemical measurements, in borehole sampling of formation fluids and sidewall minicores, and/or in handling and data processing of multiple logging tools as planned in Expedition 337.
