Age-Depth Profiles for Pacific DSDP and ODP Drillsites
INTRODUCTION
This technical report contains age-depth profiles in support of
the paper I submitted to the journal
Paleoceanography
in Feb 2002, and which is in review as of this writing. They
show the strati-graphic information I used and the age-depth curves
I constructed for each of the DSDP and ODP drillsites included in
the paper. I attempted to construct these profiles using a minimum
aston-ishment principle, i.e. smooth polynomial fits where possible
and lower order fits where strati-graphic data are scant. The
primary source of stratigraphic information were the Initial
Reports volumes for both DSDP and ODP, and the data used here are
listed in Table . If I knew of the existence of other stratigraphic
synthesis (e.g. legs 130, 138, and 167), I included that data or
used that as a primary source of the age model. See the
Paleoceanography
paper (Lyle, Neogene car-bonate burial in the Pacific Ocean )
for more information about the stratigraphy, especially Tables 1
and 2.

DSDP/ODP Drillsites in the Pacific for Paleoceanography
Figure 1: DSDP and ODP drillsites used in the compilation for
Neogene carbonate burial in the Pacific Ocean . All drillsites with
suitable sedimentary records were to be included through ODP Leg
167.
