RESEARCH INTERESTS
My research interests bridge the fields of paleoclimatology, paleoecology, archaeology,
and low-temperature geochemistry. Recent efforts
are focused on climatic and ecological archives contained in accretionary,
hard-part remains
of coastal marine shellfish and finfish from
Holocene archaeological deposits and Neogene fossil deposits. These
archives are microsampled at high resolution in the Paleoclimate & Paleoecology Laboratory. Current projects
include:
- Late Holocene subtropical climate reconstruction using geochemical
proxies in archaeological shells (Mercenaria campechiensis) and
otoliths (Ariopsis felis), southwest Florida (Karen Jo
Walker, Florida Museum of Natural History,
collaborator; Ting Wang, MS). Funded by NSF
Awards
#0455974
and
#0602422 and the American Chemical Society's Petroleum
Research Fund (Award #).
- Holocene climate archives preserved in archaeological limpet shells (Patella vulgata) from Viking deposits on the
Orkney Islands and Mesolithic, Neolithic, Bronze Age and Iron Age sites
elsewhere in Scotland (collaborators:
James Barrett,
University of Cambridge;
Nicky
Milner, University of York;
Steven Mithen, University of Reading;
Bernd Schöne, University of
Mainz; graduate students: Tracy Fenger, MS; Ting Wang, PhD candidate; Mike Mobilia,
MS candidate). Funded by the
National Geographic Society (Award #8214-07).
- Geochemical proxies in oyster shells (Ostrea edulis) to
reconstruct environmental conditions and understand changing
subsistence strategies across the Mesolithic/Neolithic transition from
hunter/gatherer to farming societies in Europe (Nicky
Milner, University of York, collaborator).
- Latitudinal changes in seasonality along the US Atlantic Coastal Plain
during Neogene warm climate intervals: Analogues for future global warming? (Joe
"Clam-boy" Carter and
Drew
Coleman, collaborators; Ann Goewert and Joel Hudley, PhD candidates)
- Reconstructing continental climate across the Pleistocene-Holocene
boundary using the isotopic composition of land snails associated with
the Clary Ranch archaeological site in western Nebraska (Matthew
Hill, Iowa State University, collaborator).
