Crooked Pond, Massachusetts Lake Level and Hydrogen Isotope DataEntry ID: NOAA_NCDC_PALEO_2006-025
Abstract: Reconstructed water-level changes between 15,000 cal yr B.P. and present,
based on sediment and pollen stratigraphies (Shuman et al. 2001). for
Crooked Pond, Massachusetts.
ABSTRACT (Shuman et al. 2001):
Sediment cores collected along a transect in Crooked Pond, southeastern
Massachusetts, provide evidence of water-level changes between 15,000 cal yr
B.P. and present. The extent of ... fine-grained, detrital, organic accumulation
in the basin, inferred from sediment and pollen stratigraphies, varied over
time and indicates low water levels between 11,200 and 8000 cal yr B.P. and
from ca. 5300 to 3200 cal yr B.P. This history is consistent with the
paleohydrology records from nearby Makepeace Cedar Swamp and other sites from
New England and eastern Canada and with temporal patterns of regional changes
in effective soil moisture inferred from pollen data. The similarities among
these records indicate that (1) regional conditions were drier than today when
white pine (Pinus strobus) grew abundantly in southern New England (11,200 to
9500 cal yr B.P.); (2) higher moisture levels existed between 8000 and 5500
cal yr B.P., possibly caused by increased meridonal circulation as the
influence of the Laurentide ice sheet waned; and (3) drier conditions possibly
contributed to the regional decline in hemlock (Tsuga) abundances at 5300 cal
yr B.P. Although sea-level rise may have been an influence, moist climatic
conditions during the late Holocene were the primary reason for a dramatic
rise in water-table elevations.
ABSTRACT (Huang et al. 2002):
The rich paleoclimate information preserved in lacustrine sedimentary organic
matter can be difficult to extract because of the mixed terrestrial and
aquatic inputs. Herein we demonstrate that compound-specific hydrogen isotope
analysis of palmitic acid, (PA), a ubiquitous compound in lacustrine
sediments, captures the dD signals of lake water. Samples collected across a
diverse range of 33 North American lakes show a strong correlation between
water and dDPA values. At Crooked Pond, Massachusetts, the dDPA changes in a
14 k.y. sediment record parallel temperature trends inferred from fossil
pollen. Downcore changes reveal differences between climatic trends in New
England and in Greenland that are consistent with important regional
differences in climate controls.
