Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program) 208 https://doi.org/10.2973/odp.proc.sr.208.202.2006 1-11 Carbon isotope ratios of terrestrial biomarkers extracted from Ocean Drilling Program Hole 1263A show a prominent negative excursion across the Paleocene/Eocene boundary. The isotope profiles of the normal alkanes nonacosane (n-C29), hentriacontane (n-C31), and tritriacontane (n-C33), the first such profiles generated with samples from a pelagic section, are similar to those of carbonate carbon, though the magnitude of the excursion is larger, roughly 4-5. In addition, the n-alkane records show an inflection at 334.70 meters composite depth, which is roughly equivalent to where the inflection occurs in the carbonate record. These results suggest that the terrestrial compounds are directly recording changes in atmospheric carbon 13C and that the actual excursion may have been larger than that recorded by marine carbonates. 2.77948 2.77948 -28.53283 -28.53283 2.77948 -28.53283 2003-03-29T15:15:00 2003-04-02T01:25:00 334.45 378.21 not specified ODP Ocean Drilling Program https://www-odp.tamu.edu:443/ Ocean Drilling Program, Texas A&M University ODP http://www-odp.tamu.edu/ https://ror.org/01f5ytq51 208-1263A -28.53283 2.77948 Walvis Ridge, Southeast Atlantic Ocean -2717.1 2003-03-29T15:15:00 2003-04-02T01:25:00 Leg208 Leg208 2003-03-06T00:00:00 2003-03-06 2003-05-06T00:00:00 2003-05-06 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html doi:10.2973/odp.proc.ir.208.2004 Joides Resolution https://www-odp.tamu.edu:443/resolutn.html Drilling/drill rig DRILL 345.6 m 295.78 m 40 cores; 345.6 m cored; 0 m drilled; 85.6 % recovery 52 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Sediment depth is given in mcd, at top horizon of the sample.
