Italian doctoral student Gulglielmo Angelo Caddeo's visit in 2009-2010 also continues to bear fruit in terms of process-oriented, rather than paleoclimatological, research on the geochemistry of speleothems. work investigated ways to extract more meaningful carbon isotopic compositions from speleothems. student James Baldini's thesis focused on relationships between drip rates and speleothem morphologies, and Joe Elkins's Ph.D.
UGA undergraduate Rachel Sellers has completed a senior thesis on one of the Spanish stalagmites. That work has focused on stalagmites from northwestern Spain, and it has been funded by the Spanish Ministry of Science and Technology. More recent collaboration has been with Juan Ramon Vidal-Romani and his colleagues at the University of La Coruna in northwestern Spain and with Fuyuan Liang of Western Illinois University. student Ny Riavo Gilbertinie Voarintsoa has now joined this effort too. thesis work by Margaret Rafter and Hillary Sletten. This work has been supported by NOAA and NSF and was the subject of M.S. Brook of the UGA Geography Department, and it has focused on stalagmites from southern Africa, the southwestern United States, China, India, and Belize. Much of this work has been done in collaboration with Dr. My work has combined the petrography of stalagmites (the distribution of spelean carbonate minerals, non-carbonate detrital minerals, crystal fabrics, layering, and critical surfaces) with geochemistry (C and O stable isotope analysis and trace-element geochemistry) to understand stalagmites as records of past climate. Petrography and Geochemistry of Stalagmites as a source of information about past climate change has been the main area of my recent research.
