Neogene Radiolarian Biostratigraphy and Faunal Evolution Rates in the Eastern Equatorial Pacific ODP Sites 845 and 1241

The biostratigraphy and paleobiology of Oligocene planktonic foraminifera from the equatorial Pacific Ocean (ODP Site 1218)

Planktonic foraminifera from a continuous Oligocene succession with clear magnetochronology and sediment cycles at Ocean Drilling Program Site 1218 (equatorial Pacific Ocean) were studied in the interval from 27 to 30 Ma. Paragloborotalia taxa are common and we examined their size, relative abundance, and stable isotopes. Multispecies stable isotope data indicate the depth habitats of Oligocene...

Paleoceanography of the eastern equatorial Pacific during the Neogene: Synthesis of Leg 138 drilling results

The primary objective of Leg 138 was to provide detailed information about the ocean's response to global climate change during the Neogene. Two north-south transects were drilled (95° and 110°W) within the region of equatorial divergence-driven upwelling (and thus high accumulation rates and resolution) and spanning the major equatorial ocean current boundaries (and thus recording a high-ampli...

Running hot and cold in the eastern equatorial Pacific

Understanding paleoceanography of the eastern equatorial Pacific is of particular importance, given its propensity for high variability on all timescales including the seasonal cycle, the interannual El Niño–Southern Oscillation (ENSO), and longer-term changes, each with possible global consequences (Cane and Clement, 1999). For example, tropical Pacific warming imposed in atmospheric climate m...
