“…In its upper reaches, outcrops of last glacial age were uncovered by erosion after extreme rainfall events in summer 2013. These outcrops are the object of ongoing sedimentological investigations (Mayr et al, 2017).…”

“…A sedimentary basin filled with fine-grained lacustrine-palustrine, coarsegrained (glaci-)fluvial deposits, and tills existed at the Nesseltalgraben site from at least MIS 5c until the LGM (Mayr et al, 2017). Previous research on these lacustrine-palustrine sediments provided a first lithological description, bulk geochemical data, and a stratigraphic inventory based on paleomagnetic data, palynology, and ten radiocarbon ages with a range from > 51.5 to 27.1 ka BP (Mayr et al, 2017). However, due to age reversals and low resolution, the previously published age model was recognized as insufficient for comparison with other highresolution paleoclimate records.…”

“…We used 4% HCl (80 °C, 1-2 h), followed by 0.5% NaOH (20 ºC, 1 h) followed by 2M H 2 SO 4 (80 ºC, 2 h) for the wet oxidation following Hatté et al (2001) rather than the K 2 Cr 4 O 7 used by Bird et al (1999). A set of ABOX-treated samples of wood, twigs, mosses, and plant remains from Nesseltalgraben was compared with previously reported dates of similar material (Mayr et al, 2017) treated with the ABA method (4% HCl, 2-3 h; 2% NaOH, 1-2 h; 4% HCl, 2-3 h, all at 60 °C). The comparison between conventional 14 C ages of samples with ABA and ABOX pre-treatments showed increasing offsets (Δ age) with increasing age (Table 1).…”

“…An aliquot of about 1 ml of selected samples, equally distributed over the profile, was homogenised with a mortar for determination of total carbon (TC), total inorganic carbon (TIC), total organic carbon (TOC), total nitrogen (TN), and total sulphur (TS). For TIC, TN, and TS about 10-50 mg of sample, depending on organic matter estimations based on a previous study (Mayr et al, 2017), were weighed together with 18 mg V 2 O 5 in tin capsules and afterwards analysed with an elemental analyser (Euro EA, Eurovector, Germany). For TOC, about 10-20 mg were weighed into silver capsules and afterwards decalcified in two steps first with 3%…”

Ravine slopes at the recently discovered Nesseltalgraben site in southeastern Germany provide a unique last glacial sediment record for the Northern Calcareous Alps. The 21 m-long profile is dominated by fine-grained lacustrine-palustrine sediments overlain by several metres of glacifluvial gravels and lodgement tills of the Last Glacial Maximum and underlain by a diamicton. The age model includes 29 radiocarbon analyses and one paleomagnetic anomaly (Laschamp event) together providing a modelled age range from c. 59 to 29.6 ka cal BP, i.e. Marine Isotope Stage (MIS) 3. Apart from a description of the lithofacies, X-ray-fluorescence (XRF) scanning and elemental analyses provide high-resolution records of the geochemical composition. Multivariate analyses of XRF data separate Ca from other major elements. Carbonate contents, represented by Ca and total inorganic carbon, reach maxima in repeatedly occurring calcareous silty to sandy layers and are related to glacigenic origin. These indicate repeated inner-alpine local glaciations during stadials of MIS 3. Scanning electron microscopy and XRF data confirm the detrital origin of these layers. In contrast, organic matter and elements more resistant to chemical weathering (Si, Ti, Zr) accumulated during interstadials and concurrently elevated Rb/Sr ratios indicate intensified weathering. The high-frequency proxy variations determined for Nesseltalgraben reflect interstadial-stadial climate variability comparable with oxygen-isotope records from Greenland ice cores and Alpine speleothems. Thus, Nesseltalgraben is among the very few independently dated sediment records from continental Europe covering the entire MIS 3 and reflecting the full Dansgaard-Oeschger climate variability.

Unravelling climate change impacts from other anthropogenic influences in a subalpine lake: a multi-proxy sediment study from Oberer Soiernsee (Northern Alps, Germany)

Mountain lakes are increasingly impacted by a series of both local and global disturbances. The present study reveals the eutrophication history of a remote subalpine lake (Oberer Soiernsee, Northern Alps, Germany), triggered by deforestation, alpine pasturing, hut construction, tourism and atmospheric deposition, and identifies the intertwined consequences of on-going global warming on the lake’s ecosystem. The primary objective was to disentangle the various direct and indirect impacts of these multiple stressors via down-core analyses. Our multi-proxy approach included subfossil diatom assemblages, carbon and nitrogen stable isotope ratios and subfossil pigments from dated sediments. Shifts within the diatom assemblages were related to variations in trophic state, lake transparency, water temperature and thermal stratification. The organic carbon isotope (δ13Corg) records, the diatom valve density and the pigment concentrations documented the development of primary production and composition. Total nitrogen isotope values (δ15N) are more likely to reflect the history of atmospheric nitrogen pollution than lake-internal processes, also mirrored by the decoupling of δ15N and δ13Corg trends. The composition of sedimentary pigments allowed a differentiation between planktonic and benthic primary production. Concordant trends of all indicators suggested that the lake ecosystem passed a climatic threshold promoted by local and long-distance atmospheric nutrient loadings.
