Pliocene

We are constructing benthic and planktic foraminiferal stable isotope records and alkenone-derived sea surface temperatures from Ocean Drilling Program Site 1208 in the northwestern subtropical Pacific spanning the early to late Pliocene climate transition. We are interested in the role of the subtropical Pacific surface ocean in the development of wide spread Northern Hemisphere Glaciation at this time. This research was funded by the NSF (OCE-0902729) and resulted in the following publications (graduate student author is marked by one asterisk):

*Venti, N., K. Billups, and T. Herbert, Sensitivity of the North Pacific to obliquity forcing during the Plio-Pleistocene climate transition, EPSL, in review.

*Venti N. and K. Billups, Surface Water Hydrography of the Kuroshio Extension during the Plio/Pleistocene climate transition, Marine Micropaleontology, 101, 106-114. Featured article in SedDB: http://www.earthchem.org/seddb

*Venti, N. L., and Billups K. Stable-isotope stratigraphy of the Pliocene-Pleistocene climate transition in the northwestern subtropical Pacific, Palaeoecology, Palaeogeography, Palaeoclimatology, doi: 10.1016/j.palaeo.2012.02.001.
