Professor During the past several years my research has involved the generation of stable isotopic and geochemical time-series data from Pacific Ocean corals and sediment cores for paleoclimatic reconstruction at resolutions that range from sub-seasonal to millennia. This high resolution is only preserved in certain marine environments and is essential for understanding the modes of climatic variability in the past. A better understanding of past climatic variability will help assess the potential anthropogenic component of global climate. Current research projects include: * (1) Using oxygen and carbon isotopes and trace metals in Pacific corals in order to reconstruct changing climatic conditions over the past several hundred years. Current project focused on developing a network of coral records from Fiji, Tonga and Samoa to examine interdecadal oceanographic variability. This is a joint project with the Lamont Doherty Earth Observatory of Columbia University. * (2) Analyzing sediment cores to reconstruct surface ocean conditions and Indonesian Throughflow over the last 20,000 years in and around the Makassar Strait in Indonesia. This is a joint project with Rutgers University and the Woods Hole Oceanographic Institution. |
