Data for Cenozoic paleoclimate on land in North America

Retallack, Greg J. (University of Oregon, 2016-04)

Paleotemperature and paleoprecipitation over the past 40 m.yr. can be inferred from the degree of chemical weathering and depth of carbonate nodules in paleosols of Oregon, Montana, and Nebraska. Paleosol records show ...
Paleosol data from Kenya.

Retallack, Greg J. (2016-11-21)

Data collected in several areas of Kenya with Cenozoic deposits well known for fossil mammals, including islands and shores of Lake Victoria, the central and southern Gregory Rift, and the basin of Lake Turkana. Data are ...
Paleosol Records of Middle Miocene Climate Change

Metzger, Christine (University of Oregon, 2013-10-10)

The middle Miocene thermal maximum (~16 Ma) was a period of global climate unusually warm and wet for the Neogene and is of interest as a paleo-analog for future climate change from anthropogenic global warming. In ...
Sedimentation, Climate Change and Tectonics: Dynamic Stratigraphy of the Pliocene-Pleistocene Fish Creek-Vallecito Basin, California

Peryam, Thomas (University of Oregon, 2012)

In order to better understand the interactions between climate change, landscape erosion and sedimentation, a detailed study was conducted on Plio-Pleistocene non-marine deposits of the Palm Spring Group in the Fish ...
Stomatal index of Ginkgo biloba as a proxy for atmospheric CO2

Conde, Giselle (University of Oregon, 2016-11-21)

This thesis presents a new calibration of the Ginkgo stomatal index as a proxy for atmospheric CO2 concentrations using leaves from modern Ginkgo biloba herbarium specimens. Scanning electron images were obtained to count ...
