attribute	NC_GLOBAL	summary	String	Marine sediments are one of the largest reservoirs of reduced carbon, but the influences controlling the amount and composition of organic matter stored for geologic time are not well understood. Mineral-associated organic matter, either bound to a mineral surface or within a larger matrix association, is thought to be non-bioavailable and sequestered within sediments. Heating of sediments, as found in hydrothermal environments and deep in the sedimentary column, has the potential to disrupt typical burial processes. We analyze subsurface sediments for the concentration and composition of organic biomarkers released via acid and base hydrolysis to improve our understanding of how heating changes the composition and distribution. This dataset contains the concentrations (in micrograms per cubic centimeter (ug/cm3)) of organic biomarkers from 5-10 meters below seafloor (mbsf), 26-30 mbsf, and 54-57 mbsf within cores U1545, U1546, and U1547 from IODP Expedition 385, Guaymas Basin Tectonics and Biosphere. IODP cores U1545, U1546, and U1547, were chosen to represent a regional background core, previously heated core, and an actively heated core, respectively. This dataset reports concentrations of biomarkers released though successive acid hydrolysis and base hydrolysis, which are performed on the same sediments following the traditional solvent extraction.
