I am a paleoclimatologist/marine geologist who studies the history and causes of climate change in the Earth's past. This page provides links to my current research, publications, and published data sets, as well as other science-related material.

I am currently looking for talented motivated graduate students and/or post-docs to work on projects related to Pliocene sea level as well as Laurentide and Antarctic ice sheet history over the late Pliocene to early Pleistocene. Our paper "Plio-Pleistocene ice volume, Antarctic climate, and the global d¹⁸O record" published in 2006 discusses one problem I continue to investigate. Our recent paper "Departures from eustasy in Pliocene sea-level records" discusses our PLIOMAX sea level project. You can download these papers by following links on my Publications page.  On-line application for post-doctoral positions can be found here.

Three Post-Doctoral Research Scientists in Paleoclimatology and Paleoceanography:

 

The Lamont-Doherty Earth Observatory of Columbia University invites applications for three full-time post-doctoral research scientist positions in the field of paleoclimatology and paleoceanography.  The successful candidates will join a dynamic and interdisciplinary group of scientists working on a wide range of interrelated problems examining past climate history, ocean chemistry and circulation, ice sheet stability, sea level, and the interactions of the solid Earth, ocean, and cryosphere. The positions are full-time 1-year appointments, with the opportunity for continuation and growth depending on progress and availability of funding.

 

We seek qualified, highly motivated candidates for the following research activities:

 

o   Past sea level changes.  The successful candidate will undertake field work and related analyses leading to a better understanding of Plio-Pleistocene sea level history.  This work will be part of the larger collaborative PLIOMAX project, and target locations in the circum-Indian and Atlantic Ocean regions; field experience and dating expertise in carbonate sedimentary environments and coral reef ecology and structure is essential.

 

Contact: Maureen Raymo (raymo@ldeo.columbia.edu)

 

o   Sediment geochemistry.  The successful candidate will investigate the history of the Laurentide ice sheet over the Plio-Pleistocene through analysis of Gulf of Mexico sediment cores; investigation of multiple proxies and innovative application of new proxies to core material is anticipated; expertise in foram geochemistry, clay mineralogy and/or XRF techniques desirable.

o   Foraminifer shell geochemistry/paleoceanographer. The successful candidate will work on one of several potential research areas including coretop calibrations of planktonic foraminifera and pteropods with oceanic carbon chemistry and physical parameters, Pliocene changes in the composition and ventilation of upper ocean waters, and high-resolution records of Holocene SST variability. The candidate will have experience with species identification, stable isotope geochemistry and analysis, and trace element analyses using ICP-MS (mid-2012 delivery).
