Evaluating Holocene climate change in northern Norway
using sediment records from two contrasting lake systems.
Journal of Paleolimnology, Vol. 48, No. 1, June 2012, pp. 259-273.
DOI: 10.1007/s10933-012-9604-7
We analyzed Holocene sedimentary records from two lakes in the Lofoten
Islands, northern Norway to evaluate environmental changes during the
Holocene related to northern North Atlantic climate dynamics. The lakes
are located in different geomorphological settings, and thus provide
a contrast in their response to regional climate change. Environmental
changes at both lakes were interpreted based on magnetic susceptibility,
organic-matter flux, C/N, d13Corg, Ti concentrations, and mass
accumulation rates. Chronologies were established using 16 AMS
radiocarbon dates, and average deposition rates in both environments
are higher than 0.2 mm/year throughout the Holocene. At Vikjordvatnet,
sedimentary geochemical properties define three distinct phases of
sedimentation related to changes in aquatic productivity and gradual
landscape development. Following deglaciation, during the early Holocene
(11.6–7.2 ka), aquatic productivity increased and the landscape
stabilized as regional temperatures increased in response to higher
summer insolation and increasing inflow of warm Atlantic water into
the Norwegian Sea. Centennial-scale intervals of decreased organic-
matter flux, from 10.9 to 10.2 ka and 9.2 to 8.0 ka, record episodes
of instability during the early Holocene. These may represent regional
cooling events related to freshwater forcing and a slowdown of
the northward transport of warm water into the North Atlantic.
During the mid-Holocene (7.2–4.8 ka) organic-matter properties show
less variability and the timing of this phase corresponds with the
regional Holocene thermal maximum. The late Holocene sediments
(4.8 ka–present) record a transition to colder climate conditions.
The record from Fiskebølvatnet captures periodic changes in clastic
input related to runoff and exhibits high-frequency variations over
the last 9.5 ka. The most significant change in sedimentation was
during the late Holocene (4.3 ka–present) when the frequency
and magnitude of runoff events show an abrupt transition to wetter
conditions. The timing of this shift corresponds to other regional
reconstructions that indicate wetter and colder conditions during
the late Holocene.
STUDY NOTES: Multiproxy Holocene sediment data from 2 lakes in the Lofoten Islands,
northern Norway. Paleoenvironmental proxies measured include magnetic
susceptibility, organic-matter flux, C/N, d13Corg, Ti concentrations,
and mass accumulation rates.
