Abbreviations:  DSDP, Deep Sea Drilling Project; 
mbsf, meters below sea floor;
Hole, hole number drilled at the DSDP site of the same number 
(multiple holes at a single site are given letter designations; 
e.g. Holes 603, 603A, and 603B were drilled at DSDP Site 603); 
Core, number of 9.5-m-long core drilled in that hole; 
Sect., number of 1.5-m-long (150 cm) section cut from each core, 
Section 1 being the top of the core; 
Int., interval, in centimeters, within each section, 
0 cm being the top of the section, 150 cm being the bottom of a complete section; 
TOC, total organic carbon; R-E, Rock-Eval pyrolysis; HC, hydrocarbons; 
ICP, inductively coupled, argon plasma emission spectrometry; XRF, X-ray fluorescence
