We report the results of downhole stable isotopic (d13Corg [organic carbon] and d15N) and elemental measurements (total organic carbon [TOC], total nitrogen [TN], and carbon/nitrogen [C/N]) of sedimentary organic matter (SOM) along with stable isotopic measurements (d18O and d13C) of left-coiling Ne...

We report the results of downhole stable isotopic (d13Corg [organic carbon] and d15N) and elemental measurements (total organic carbon [TOC], total nitrogen [TN], and carbon/nitrogen [C/N]) of sedimentary organic matter (SOM) along with stable isotopic measurements (d18O and d13C) of left-coiling Neogloboquadrina pachyderma planktonic foraminifers from Ocean Drilling Program Site 1166.
