Abstract
To reconstruct the climate history of the equatorial Pacific, one
major objective of the Pacific Equatorial Age Transect (PEAT) pro-
gram is to compile a Cenozoic megasplice that integrates all avail-
able bio-, chemo-, and magnetostratigraphic data including key
records from Ocean Drilling Program (ODP) Leg 199. In order to
do so, extended postcruise refinements of the shipboard compos-
ite depth scales and composite records are required. Here, we pres-
ent a revised depth scale of Integrated Ocean Drilling Program
(IODP) Expedition 320 Sites U1331, U1332, U1333, and U1334 as
well as Leg 199 Sites 1218, 1219, and 1220. The revised composite
records were used to perform site-to-site correlation and integra-
tion of Leg 199 and Expedition 320 sites. Based on this decimeter-
scale correlation, a high-resolution integrated paleomagnetic, cal-
careous nannofossil, and radiolarian stratigraphy for the equato-
rial Pacific is established that covers the time from 20 to 40 Ma.
This sedimentary compendium from the equatorial Pacific will be
