Climate Science

Behavior of Earth's climate revealed through isotopic and chemical signals. Recent and ongoing studies have included stable isotope and chemical analyses of microfossils, speleothems, and tree rings, as well as selected organic molecules from ocean and lacustrine sediments. Recent and ongoing study areas include oceanic sites from the Indian Ocean and coastal California, trees from California, Southeast Asia and New Zealand, speleothems from India, China and Peru, and lakes from Southern California.
