Late-Cretaceous Recent paleoclimate and paleoceanography using benthic foraminifera and stable isotopes. Topics include deep-sea research using samples from the Ocean Drilling Program to study the asteroid impact at the end of the Cretaceous, early Cenozoic extreme warm climates (including effects of ocean acidification and deoxygenation), establishment of the Antarctic ice sheet at the end of the Eocene and the beginning of the Oligocene, increased glaciation in the middle Miocene, and the effects of these events on deep-sea biota. In addition, foraminifera are the tools used to study anthropogenic eutrophication, recent climate change and acidification Long Island Sound and Great Salt Pond, Block Island, and rates of recent sea level rise and ecological changes in coastal salt marshes (in cooperation with faculty in EEB and FES and the Peabody Museum).
