Lake and catchment response to Holocene environmental change:
spatial variability along a climate gradient in southwest Greenland.
Journal of Paleolimnology, Vol. 48, No. 1, June 2012, pp. 209-222.
DOI: 10.1007/s10933-012-9616-3
The Kangerlussuaq area of southwest Greenland is a lake-rich landscape
that covers a climate gradient: a more maritime, cooler and wetter
coastal zone contrasts with a dry, continental interior. Radiocarbon-
dated sediment sequences (covering ~11,200-8,300 cal year) from paired
lakes at the coast and the head of the fjord were analysed for
lithostratigraphic variables (organic-matter content, bulk density,
Ti, Ca). Minerogenic and carbon accumulation rates from the four lakes
were compared to determine catchment and lake response to Holocene
climatic variability. Catchment erosion at the coast was dominated by
cryonival processes, with considerable sediment production due to the
limited vegetation cover and exposed rock faces. Input of minerogenic
sediment at one site (AT4) was high (>1 gDW cm-2 year-1) during the
period 5,800-4,000 cal year BP, perhaps reflecting intensification
of cryogenic processes on northeast-facing slopes and rapid delivery
to the lake. This period of erosional activity was not observed at
the nearby, higher elevation site (AT1) due to the lower catchment
relief; instead, there was an abrupt decline in carbon and minerogenic
accumulation rates at ~5,800 cal year BP. Sediment accumulation rates
at the inland sites were much lower (<0.005 gDW cm-2 year-1) reflecting
greater catchment stability (more extensive vegetation cover), lower
relief and substantially lower precipitation, but synchronous increases
in mineral accumulation rates from ~1,200 to 1,000 cal year BP may
reflect wind erosion associated with regional cooling and local aridity.
Carbon-accumulation-rate profiles were similar at the two inland sites,
with higher-than-average accumulation (~6-8 g C m-2 year-1) during
the early Holocene and a subsequent decline after ~6,000 cal year BP.
At the inland lakes, both mineral and carbon accumulation rates exhibited
a stronger link to climate, driven by trends in effective precipitation
and regional aeolian activity. Catchment differences (relief, altitude)
lead to more individualistic records in both erosion history and lake
productivity at the coast.
STUDY NOTES: Multiproxy Holocene sediment data from 4 lakes in Kangerlussuaq,
southwest Greenland. The lakes sampled include two near the coast
(AT1 and AT4) and two at the head of the fjord (SS1381 and SS8).
Paleoenvironmental proxies measured include Loss-on-Ignition (LOI),
Mass Accumulation Rate (MAR), bulk density, plus Calcium and Titanium
content derived from XRF.
