My group specializes in high resolution studies of climatic and oceanic variability during modern times as well as over the past 50 to 12,000 years. Our most productive archives for this work include the skeletons of long-lived corals from the tropics and the deep sea, as well as sediments from lakes and marine environments. We use chemical, isotopic, and morphological measurements of these materials to investigate the timing and rates of change associated with past solar and C cycle excursions. Current field areas include the Galápagos Islands, Antarctica, the Line Islands, Kenya, Easter Island, Chile, Patagonian Argentina, Tierra del Fuego, and Palau. We are also well into a multi-year effort to collect deep sea corals to better understand their ecology as well as their self-contained records of change in the deep sea. We do this work using deep diving research submersibles in the Gulf of Alaska and the central tropical and north Pacific.
