DESCRIPTION:
ODP Site 797 
Latitude: 38.616 degrees N 
Longitude: 134.536 degrees E 
Bathymetry: 2862.2 m 

The site is slightly above the basin plain, which prevents turbidite deposition.
Methods described in Tada, Irino, Koizumi Paleoceanography PA 900016. 
Chronostratigraphic information described in Tada, Irino, Koizumi 
Paleoceanography PA 90001.

Table A1 Contents: organic carbon, carbonate carbon, pyrite, pyrite 
sulfur/organic carbon ratio, DOP(degree of pyritization), presence of 
lamination,inferred bottom water oxygenation level, warm-water diatom 
abundance, Paralia sulcata (coastal-water diatom) abundance, and P. sulcata 
fraction of 217 samples from ODP Site 797 which covers the last 200 kys. 
 
Variable names and units: 
Org-C (wt%), 
Carb-C (wt%), 
Pyrite-S (wt%), 
S/C = Pyrite-S/org-C (no unit), 
DOP = Degree of Pyritization (no unit), 
presence of lamination (describe as lamination when it is present), 
Oxygenation level (three ranks, oxic, suboxic, euxinic), 
WWD Abundance = Warm-Water Diatom Abundance (10^6/g), 
Paralia sulucata Abundance (10^6/g), 
P. sulcata fraction (%) 
Data precision: For Org-C, Carb-C, presision is better than + 0.05 wt%. 
For Pyrite-S, precision is better than + 0.1 wt%
