Construction of the Calendar Timescale for Lake Wigry (Ne Poland) Sediments on the Basis of Radiocarbon Dating

Abstract

ABSTRACT.A radiocarbon chronology of lake sediments deposited in Lake Wigry during the Last Glacial and Holocene periods provided the basis for calendar age-depth modeling. Various fractions (organics and carbonates) were dated and the results were subjected to critical analysis. The dates affected by reservoir effects as well as outlying data were excluded, and the non-linear age model was developed based on 13 ages. The statistical tools used for construction of the models include the Bayesian analysis, applied for calibration of 14 C dates with regard to stratigraphical position of the samples, and generalized additive models (GAM).

Lithology of the Profundal Sediments in Słupiańska Bay (Wigry Lake, NE Poland) - Introduction to Interdisciplinary Study

“…Sandy muds with plant detritus and admixture of sand and gravel observed in the base of the profile are characteristic for the lake forming stage (Stasiak, 1971;Więckowski, 1988). Fine-grained carbonate deposits, mainly lacustrine chalk, typical for Słupiańska Bay , are connected with the Piotrowska et al (2007), Chronozones according Mangerud et al (1974) in interpretation of Kupryjanowicz (2007).…”

“…Other analyses of lacustrine sediments of Wigry Lake are presented in following papers: Kupryjanowicz (2007), Piotrowska et al (2007) and Zawisza and Szeroczyński (2007).…”

Postglacial Development of Vegetation in the Vicinity of the Wigry lake

“…Interdisciplinary project elaborated by Professor Jacek Rutkowski contained numerous radiocarbon (Piotrowska and Hajdas, 2006;Piotrowska et al, 2007) and lead (Gąsiorowski and Hercman, unpublished) dating, pollen analysis (Kupryjanowicz, 2004a;2006a;2006b andPiotrowska, 2005), Cladocera analysis , diatom analysis and lithological and chemical analyses (Rutkowski et al, 2002a;2002b;2006a;2006b;Osadczuk et al, 2006) of examined profiles. It created an exceptional chance for modern detailed paleoecological reconstruction.…”

Interdisciplinary studies of spring mire deposits from Radzików (South Podlasie Lowland, East Poland) and their significance for palaeoenvironmental reconstructions

“…For the five samples from the bottom part of the core (depth 130-300cm) an attempt to construct continuous calendar age-depth model was undertaken, similar to the previously reported by De Vleeschouwer et al (2009) for peat deposit or Piotrowska et al (2007) for lake sediments. For this purpose the calibration of radiocarbon dates was performed including information of stratigraphic position of samples with the use of P_Sequence function in OxCal programme (Bronk Ramsey, 2008).…”
