Leaf wax d2H and varve-thickness climate proxies from
proglacial lake sediments, Baffin Island, Arctic Canada.
Journal of Paleolimnology, Vol. 48, No. 1, June 2012, pp. 193-207.
DOI: 10.1007/s10933-012-9584-7
We present a multiproxy paleoclimate record using leaf wax hydrogen
isotopes (d2Hwax) and varve thickness from Arctic proglacial lake
sediments. We also provide one of the first evaluations of the
utility of d2Hwax as a paleoclimate proxy in Arctic proglacial lakes.
We compare varve thickness and d2Hwax at sub-decadal resolution from
1948 to 2004 AD, and at sub-centennial resolution from 1450 to 2004 AD.
Varve thickness and d2Hwax both contain large interannual variability
and are anti-correlated during the late twentieth century, suggesting
that both proxies respond rapidly, but by different mechanisms,
to catchment-scale forcings. At longer time scales, varve thickness
exhibits a strong response to Little Ice Age cooling (1661-1827 AD
in this record) but does not show evidence for twentieth century
warming recorded throughout the Arctic. d2Hwax does record regional-
scale temperature changes, with more 2H-depleted values during the
Little Ice Age and an abrupt change to more 2H-enriched values
in the twentieth century. This corresponds well with a recent
Arctic-wide temperature reconstruction in which the seventeenth
century is the coldest interval, and the twentieth century is the
warmest interval. Our results suggest that d2Hwax is a promising proxy
that can be applied at high resolution in proglacial Arctic lakes.
STUDY NOTES: Leaf wax hydrogen isotope data (d2Hwax) and varve thickness data
from sediments collected in proglacial Ayr Lake, eastern Baffin Island,
Arctic Canada.
Ayr Lake, Baffin Island: 70.459°N, 70.086°W, 68m elevation, ~50m depth.
