An expanded and largely complete upper Paleocene to upper Eocene section was
recovered from the pelagic cap overlying Allison Guyot, Mid‐Pacific Mountains at Ocean
Drilling Program (ODP) Site 865 (18° 26′ N, 179° 33′ W; paleodepth 1300–1500 m).
Reconstructions show that the site was within a few degrees of the equator during the
Paleogene. Because no other Paleogene sections have been recovered in the Pacific
Ocean at such a low latitude, Site 865 provides a unique record of equatorial Pacific …

Reconstructions show that the site was within a few degrees of the equator during the
Paleogene. The δ 1 8 O and δ 1 3 C stratigraphies from Site 865 are generally similar to
those derived from other Paleocene and Eocene sections. The planktonic foraminiferal
records, however, include significantly less short-term, single-sample variability than those
from higher-latitude sites. Peak sea surface temperatures of 24°-25° C occurred in the
earliest Eocene, followed by a rapid cooling of 3-6° C in the late early Eocene. Equatorial …
