Holocene climate change and landscape development from a low-Arctic
tundra lake in the western Hudson Bay region of Manitoba, Canada.
Journal of Paleolimnology, Vol. 48, No. 1, June 2012, pp. 175-192.
DOI: 10.1007/s10933-012-9619-0
The low-Arctic region of western Hudson Bay in interior Canada
is one of the most poorly described areas of North America
in terms of Holocene climate history. Here, we present new data
from a well-dated lake sediment core from northern Manitoba, Canada.
We assemble one of the richest multi-proxy datasets to date for a
low-Arctic lake and characterize terrestrial and lake processes
and exchanges between them. These proxies include fossil pollen
and diatom assemblages, charcoal, magnetic properties (susceptibility
and remanance), mineral grain size, bulk density, organic-matter
content, elemental geochemistry, sediment cation (K+, Mg2+, Ca2+,
Fe2+/Fe3+) and macronutrient (P, N, C) contents, biogenic-silica
content, basal peat dates (wetland initiation), and stable isotopes
(d13C, d15N). The sediment proxies record both broad- and fine-scale
(millennial and sub-millennial) climate change. We find indirect
evidence for a cool and dry post-glacial period from 9,000 to 6,500
cal yr BP, a warm and moist mid-Holocene period from 6,500 to 2,500
cal yr BP, and a cool and moist late-Holocene period from 2,500
cal yr BP to present. High-resolution geochemical data suggests
300- to 500-year-long dry periods at ~6,500-6,100, 5,300-5,000,
3,300-2,800, and 400-0 cal yr BP. These results suggest that
terrestrial and aquatic ecosystem dynamics in the western Hudson Bay
region are sensitive to past climate change and are likely to respond
to future changes in temperature and precipitation.
STUDY NOTES: Multiproxy sediment data from Unit Lake, Manitoba for the past
12,000 years. Paleoenvironmental proxies measured include
fossil pollen and diatom assemblages, charcoal, magnetic properties
(susceptibility and remanance), mineral grain size, bulk density,
organic-matter content, elemental geochemistry, sediment cation
(K+, Mg2+, Ca2+, Fe2+/Fe3+) and macronutrient (P, N, C) contents,
biogenic-silica content, basal peat dates (wetland initiation),
and stable isotopes (d13C, d15N).
