CLIMATE RECONSTRUCTION: My current research is focused on two primary objectives: (1) developing the use of massive coral skeletons for paleoclimatic reconstruction, particularly in the Southwest Pacific and Indonesia, and (2) developing sediment records of Western Pacific Warm Pool climate and Indonesian Oceanographic Throughflow variability. Modern coral skeletons can provide near-monthly resolved and continuous records of changing oceanographic conditions over the last 500+ years. Deep sea sediment cores can extend the paleoclimatic record back Millions of years.  I have just returned from Integrated Ocean Discovery Program 363 in the Western Pacific and will be analyzing interesting sediment cores from just north of New Guinea (Sites U1486 and U1487) over the next several years.  See:
