John is a Scientist Emeritus with the Geology, Minerals, Energy, and Geophysics Science center in Menlo Park, CA.
John is a marine micropaleontologist (diatoms) with expertise in and biostratigraphy and paleoceanography. His biostratigraphic expertise extends from the Late Cretaceous to the Holocene, with an emphasis on the North Pacific, eastern equatorial Pacific, and Southern Ocean. John's paleoclimate expertise is mostly on the Holocene of the North Pacific, ranging from the Gulf of California to the Gulf of Alaska. As an Emeritus Research Geologist, his research is directed toward developing and comparing Holocene sea surface temperature records in these eastern North Pacific regions with hydroclimate records in western North America and suggesting links.
