Summary: Multiple geochemical analyses (total carbon [TC], total nitrogen [TN], total sulfur, isotopic compositions of δ13Corg and δ15Norg, and Rock-Eval pyrolysis) were performed on bulk sediment samples from Integrated Ocean Drilling Program Expedition 344 to assess geochemical characteristics and variations with depth at each drilled site. Downcore profiles of geochemical analyses vary with site and composition and do not correlate with lithostratigraphic units. In addition, the downcore profiles of TC, total organic carbon (TOC), total inorganic carbon (TIC), and TN analyzed postcruise displayed similar trends to those determined from onboard analyses at all sites. Based on Rock-Eval pyrolysis, most of the organic matter is at an immature stage of Type III (vascular land plants) evolution, which is inconsistent with the results from TOC/TN, δ13Corg, and δ15Norg that indicated that most of the organic matter originates from an admixture of marine and freshwater algae (Sites U1380 and U1413) or from marine algae (Site U1412).
