Paleoclimate data provide the opportunity to understand the earth’s climate system on timescales from decades to millennia, as well as the frequency and magnitude of extreme events. This information cannot be robustly determined from relatively short instrumental observations alone. My research will develop an extensive network of precisely dated and annually-resolved late Holocene tree-ring chronologies from living and preserved (subfossil) Atlantic White cedar (AWC) forests throughout the northeastern United States that will be used to determine the precise timing, frequency, and spatial pattern of past coastal New England extreme storms. These data will be used to improve and extend the climate history of New England and to identify the occurrence, frequency, and broad-scale climate context of hurricane and powerful nor’easter events. These data are a novel high-precision paleoclimate proxy that will help provide essential information about extreme events affecting the heavily populated coast of the northeastern United States.
