“…5). A similar decrease in vascular plant n-alkane dD values between 3200 and 2000 varve a BP was observed in Meerfelder Maar by Rach et al (2017) and attributed to a change in the atmospheric circulation pattern towards a negative NAO mode. Both pollen-and diatom-inferred precipitation reconstructions in the region suggest a decreasing trend in precipitation since the Middle Holocene ( Fig.…”

Rethemeyer, J. 2019 (April) : Neoglacial transition of atmospheric circulation patterns over Fennoscandia recorded in Holocene Lake Tornetr€ ask sediments. Boreas, Vol. 48, pp. 287-298. https://doi.org/10.1111/bor.12365. ISSN 0300-9483.Atmospheric circulation over the North Atlantic has undergone significant fluctuations during the Holocene. To better constrain these changes and their impacts on the Fennoscandian subarctic, we investigated molecular and inorganic proxies as well as plant wax D/H isotopes (dD C28 ) in a Holocene sedimentary record from Lake Tornetr€ ask (Sweden). These data indicate a thermal maximum c. 8100 to 6300 cal. a BP with reduced soil organic matter input, followed by a long-term cooling trend with increasing soil erosion. dD data suggest a stable atmospheric circulation with predominance of westerly flow and North Atlantic moisture sourcing during the Early and Middle Holocene. A substantial depletion in dD followed by increased flood frequency starting at c. 5300 cal. a BP and intensifying c. 1500 cal. a BP suggests a reorganization of the atmospheric circulation from zonal towards meridional flow with predominantly Arctic Ocean and Baltic Sea moisture sourcing.

We reconstructed middle to late Holocene changes in atmospheric circulation patterns and vegetation in north-west Europe by applying novel geochemical techniques to the sediment record of Lake Uddelermeer (The Netherlands). A comparison of higher plant-derived leaf wax n-alkane distributions archived in the lake sediments with those in living plant material, combined with palynological analysis, indicates that the vegetation immediately surrounding the lake became more open at 3150 cal a BP, while the regional vegetation responded more gradually and $650 years later. Our record of the hydrogen isotopic composition of plant leaf waxes (dD wax ) shows a deuterium enrichment starting from 3500 cal a BP, which we interpret as a change in atmospheric circulation. A similar dD wax record from nearby Meerfelder Maar (Germany) shows an opposite trend around this time, which could be explained by a change in sea-level pressure resembling a negative North Atlantic Oscillation phase. This could account for depleted dD values of precipitation at Meerfelder Maar, while confounding factors related to the more maritime position of Uddelermeer cause the opposite shift there.

To reconstruct past environmental changes, a range of indirect or proxy approaches can be applied to Quaternary archives. Here, we review the complementary and novel insights that have been provided by the analysis of chemical fossils (biomarkers). Biomarkers have a biological source that can be highly specific (e.g. produced by a small group of organisms) or more general. We show that biomarkers are able to quantify key climate variables (particularly water and air temperature) and can provide qualitative evidence for changes in hydrology, vegetation, human–environment interactions and biogeochemical cycling. In many settings, biomarker proxies provide the opportunity to simultaneously reconstruct multiple climate or environmental variables, alongside complementary and long‐established approaches to palaeoenvironmental reconstruction. Multi‐proxy studies have provided rich sets of data to explore both the drivers and impacts of palaeoenvironmental change. As new biomarker proxies continue to be developed and refined, there is further potential to answer emerging questions for Quaternary science and environmental change.
