Climate variability in New England during the Holocene
Climate-scale climate variability in New England during the Holocene: New insights from compound-specific hydrogen isotope analysis. This research aims to acquire the first set of centennial-scale, high-resolution hydrogen isotope records of Holocene climate variations for New England from five selected lakes. We will apply the new approach of compound-specific hydrogen isotope analyses of palmitic acid, which has been validated by an extensive calibration using surface lake sediments and downcore studies (Huang et al., 2002).
The lakes selected lie in a south to north transect, and have similar hydrology to Crooked Pond, MA which has been shown to record the temperature changes for the last 14,000 cal. years (Huang et al., 2002; Shuman et al., 2003). One core (Pout Pond) has annual lamination, allowing further calibration of our hydrogen isotope proxy against instrumental records. The approach is particularly suited for studying New England lakes because carbonate minerals (which have provided numerous high-resolution climate records based on d18O values) are not preserved in New England lake sediments.
