Abstract Geological evidence for modeled Younger Dryas ice expansion in northern Maine is assessed in conjunction with temperature and precipitation estimates from chironomids and pollen, and plant macrofossil and lake-level analyses from lake sediment. Pollen and chironomid temperature and precipitation transfer-function estimates for the Allerød warming period indicate colder winters, precipitation levels half that of modern times, and summer temperatures near modern levels. The combination… 
The Younger Dryas in palynological records from the northern Northwest Atlantic: Does the terrestrial record lag the marine and air records?
Abstract Major changes in both pollen and dinocyst assemblages are recorded during the Younger Dryas in Bay of Islands and are associated with large drops in air and sea surface temperatures, and sea
A Natural History of Northern Maine, Usa, since Deglaciation
Abstract - We present a multi-proxy, postglacial paleorecord from Chase Lake, a 1.63-km2 drainage lake in northern Maine. This record, along with published paleorecords from several smaller lakes and
Deglaciation and late-glacial climate change in the White Mountains, New Hampshire, USA
Abstract Recession of the Laurentide Ice Sheet from northern New Hampshire was interrupted by the Littleton-Bethlehem (L-B) readvance and deposition of the extensive White Mountain Moraine System
An updated radiocarbon-based ice margin chronology for the last deglaciation of the North American Ice Sheet Complex
Abstract The North American Ice Sheet Complex (NAISC; consisting of the Laurentide, Cordilleran and Innuitian ice sheets) was the largest ice mass to repeatedly grow and decay in the Northern
Middle and Late Paleoindian Adaptation to the Landscapes of Southeastern Québec
ABSTRACT We describe the physical and vegetational landscapes prevailing before, during, and after the Younger Dryas interval within and beyond the Eastern Townships of southernmost Québec. In the
Source-to-sink system in the south bank of Qinghai Lake
Numerous alluvial fans and coastal deposits have been developed on the south bank of Qinghai Lake. The depositional system is a typical source-to-sink system in terms of developmental position and


Rapid response of forested vegetation to multiple climatic oscillations during the last deglaciation in the northeastern United States
Abstract Isotopic and pollen results from a marl lake (White Lake) in the Mid-Atlantic region of USA indicate the coupling of climate and vegetation changes. Oxygen isotopes of calcite from this site
Holocene climate and vegetation change on Victoria Island, western Canadian Arctic
Abstract A detailed pollen record from Victoria Island provides the first quantitative Holocene climate reconstruction from the western Canadian Arctic. The pollen percentage data indicate that
A review of multi-proxy data for the younger dryas in Atlantic Canada
Abstract Multi-proxy data obtained from lake sediments and buried organic sequences is reviewed and discussed as evidence for the Younger Dryas cooling event in Atlantic Canada. Sedimentological
A Paleoindian response to Younger Dryas climate change
Abstract Late Quaternary changes in North American vegetation and geography reflect the influence of changing climate induced by the retreating ice sheets, orbitally-driven seasonal insolation
Aller�d—Younger Dryas Lake Temperatures from Midge Fossils in Atlantic Canada
The distribution of species in a core from Splan Pond in Atlantic Canada indicates that there were abrupt transitions in late-glacial temperatures between warm and cold states, correlative with the well-known warm Aller�d and cold Younger Dryas events in Europe.
A previously unrecognized late-glacial cold event in eastern North America
THE transition between the last glacial period and the present interglacial was marked by pronounced and abrupt changes in climate1,2, one of which, the Younger Dryas event, resulted in a return to
Chironomid Evidence for Late-Glacial Climatic Reversals in Maine
Previously published pollen studies from Maine have not identified any late-glacial reversals despite evidence for them from adjacent areas. The distribution and abundance of midge flies are strongly
Exceptionally steep north–south gradients in lake temperatures during the last deglaciation
During the transition from the last glacial to the present interglacial climate (late-glacial period), high summer insolation1 combined with the presence of the Laurentide ice sheet is thought to
Lateglacial climate change in the White Mountains of New Hampshire
Abstract Previous paleoecological studies of vegetation change based on pollen and plant macrofossil analyses have shown no evidence of Lateglacial climate reversals in the White Mountains of New
Alnus as an indicator taxon of the Younger Dryas cooling in eastern North America
Abstract The Younger Dryas cold interval (ca. 10.8-10 ka BP) in eastern North America has been documented throughout Atlantic Canada and parts of northeastern U.S.A. Due to differences in latitude
