abstract = {Lacustrine sediments in north-eastern Germany have rarely
been used as archives to address the effects of climate
change and human impact on both lake ecosystem and landscape
evolution for this region. Sacrower See, a hardwater lake
located in Brandenburg, provides a unique sediment record
covering the past 13,000 years which was used to reconstruct
climatic and anthropogenic forcing on lacustrine
sedimentation. Time control is provided by 12 AMS C-14 dates
of terrestrial plant remains, the Laacher See Tephra, and
the onset of varve formation in AD 1870 (80 cal. BP).
Geochemical (including XRF logging of major elements, CNS
analyses as well as delta C-13(org) and delta N-15
measurements) and pollen analyses allowed detecting detailed
environmental changes in the sediment record. During the
Younger Dryas cold phase increased soil erosion and
hypolimnetic oxygen depletion enhanced the nutrient supply
to the lake water causing eutrophic conditions. The
beginning of the Holocene is characterized by large changes
in C/N ratios, total sulphur, delta C-13 of bulk organic
matter as well as in K, Si, and Ti, reflecting the response
of the lake's catchment to climatic warming. Reforestation
reduced the influx of detrital particles and terrestrial
organic matter. The first, rather weak evidence of human
impact is documented only in the pollen record at 5,500 cal.
BP. However, until 3,200 cal. BP sedimentological and
geochemical parameters indicate relatively stable
environmental conditions. During periods of intense human
impact at around 3,200, 2,800, and 900 cal. BP peaks in Ti
and K represent phases of increased soil erosion due to
forest clearing during the Bronze Age, Iron Age, and
Medieval Times, respectively. In general, greater variation
is observed in most variables during these perturbations,
indicating less stable environmental conditions. The steady
rise of biogenic silica accumulation rates during the
Holocene reflects an increasing productivity of Sacrower See
until diatoms were outcompeted by other algae during the
last centuries. The applied multi-proxy approach fosters the
interpretation of the sediment record to reveal a consistent
picture of environmental change including environmental
factors controlling lake ontogeny and the effects of human
impact.},
