“…Correlation between the chrysophyte-based DB4 C reconstruction and the homogenized air temperature series for Lake _ Zabi nskie (Larocque-Tobler et al, 2015) is highest for JanuaryeMarch temperatures (3-years filter; R ¼ À0.35, p > 0.05). Although a better correlation would be expected, this is explained because of distorting effects of ice-cover.…”

“…A synthesis of the longest tree-ring based climate reconstructions for Poland is presented by Zielski et al (2010). Most surprisingly, studies using varved lake sediments are missing despite their demonstrated potential for quantitative seasonal paleoclimate studies (Amann et al, 2014;Bonk et al, 2015;Larocque-Tobler et al, 2015). Recent work has also highlighted the potential of raised bogs as paleoenvironmental and paleoclimate archives in Poland (De Vleeschouwer et al, 2009;Gałka et al, 2014;Lamentowicz et al, 2015).…”

a b s t r a c tChrysophyte cysts are recognized as powerful proxies of cold-season temperatures. In this paper we use the relationship between chrysophyte assemblages and the number of days below 4 C (DB4 C) in the epilimnion of a lake in northern Poland to develop a transfer function and to reconstruct winter severity in Poland for the last millennium. DB4 C is a climate variable related to the length of the winter. Multivariate ordination techniques were used to study the distribution of chrysophytes from sediment traps of 37 low-land lakes distributed along a variety of environmental and climatic gradients in northern Poland. Of all the environmental variables measured, stepwise variable selection and individual Redundancy analyses (RDA) identified DB4 C as the most important variable for chrysophytes, explaining a portion of variance independent of variables related to water chemistry (conductivity, chlorides, K, sulfates), which were also important. A quantitative transfer function was created to estimate DB4 C from sedimentary assemblages using partial least square regression (PLS). The twocomponent model (PLS-2) had a coefficient of determination of R 2 cross ¼ 0.58, with root mean squared error of prediction (RMSEP, based on leave-one-out) of 3.41 days. The resulting transfer function was applied to an annually-varved sediment core from Lake _ Zabi nskie, providing a new sub-decadal quantitative reconstruction of DB4 C with high chronological accuracy for the period AD 1000e2010. During Medieval Times (AD 1180e1440) winters were generally shorter (warmer) except for a decade with very long and severe winters around AD 1260e1270 (following the AD 1258 volcanic eruption). The 16th and 17th centuries and the beginning of the 19th century experienced very long severe winters. Comparison with other European cold-season reconstructions and atmospheric indices for this region indicates that large parts of the winter variability (reconstructed DB4 C) is due to the interplay between the oscillations of the zonal flow controlled by the North Atlantic Oscillation (NAO) and the influence of continental anticyclonic systems (Siberian High, East Atlantic/Western Russia pattern). Differences with other European records are attributed to geographic climatological differences between Poland and Western Europe (Low Countries, Alps). Striking correspondence between the combined volcanic and solar forcing and the DB4 C reconstruction prior to the 20th century suggests that winter climate in Poland responds mostly to natural forced variability (volcanic and solar) and the influence of unforced variability is low.

“…Our aim is to understand the relationship between lake water properties and sedimentformation processes in Lake Żabińskie. This lake has revealed excellent preservation of biogenic varves with high sedimentation rates, which offers a great potential for highresolution, quantitative paleoclimate reconstructions of the past millennium and beyond (Tylmann et al, 2013b;Amann et al, 2014;Hernández-Almeida et al, 2015;Larocque-Tobler et al, 2015). To exploit this potential, conditions for the deposition of these varved sediments must be recognized as a prerequisite for a reliable varve chronology and an appropriate interpretation of multi-proxy records.…”

“…The exceptional scientific value of this site is due to a very good preservation of varves in the sediments and high sedimentation rates which allow high-resolution (annual) analysis of different proxies. The lake already showed its high potential for quantitative paleoenvironmental reconstructions (Amann et al, 2014;Hernández-Almeida et al, 2015;Larocque-Tobler et al, 2015). Therefore, the best possible accuracy of the chronology is crucial for the reliability of the millennial-long climate reconstructions derived from the sediments of this lake.…”

Varved lake sediments from Lake Żabińskie (northeastern Poland) provide a highresolution calendar-year chronology which allows validation of 14 C dating results. Microscopic analysis of the varve microfacies revealed that laminations found in Lake Żabińskie were biogenic (calcite) varves. Three independent counts indicated a good preservation quality of laminae in the 348 cm long sediment profile which contained 1000 +12 / -24 varves. The varve chronology was validated with the 137 Cs activity peaks, the tephra horizon from the Askja eruption at AD 1875 and with the timing of major land-use changes of known age inferred from pollen analysis. 32 AMS 14 C dates of terrestrial macrofossils distributed along the profile were compared with the varve chronology. After identification of outliers, the free-shape model performed with 21 14 C dates provided the best possible fit with the varve chronology. We observed almost ideal consistency between both chronologies from the present until AD 1250 while in the lower part (AD 1000-1250) the difference increases to ca. 25 years. We demonstrate that this offset can be explained by too old radiocarbon ages of plant remains transported to the lake by the inflowing creek. Results of this study highlight that careful interpretation of radiocarbon age-depth models is necessary, especially in lakes where no annual laminations are observed and no independent method are used for cross-validation.
