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

Abstract

Abstract:In this paper, a lithological study taking into account trace metals of the profundal sediments from Słupiańska Bay in Wigry Lake is presented. A profile 5.26 m long has sandy muds at the bottom and moving upwards layers of calcareous gyttja, lacustrine chalk, and again calcareous gyttja are present. The profile is continuous, typical for the sediments of NE Poland formed from Allerøde to recent time. The results of the lithological analysis were correlated with results of high-resolution seismic survey. The results together with radiocarbon dating are part of interdisciplinary complex research comprising paleobiological study of pollen, Cladocera, diatom successions and human activity, which will be published in successive papers.

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

“…The lake water varies from eutrophic in the northern part to mesotrophic southern basins, including also Slupianska Bay. More detailed water chemistry data are included in Stawecki et al (2003) and Rutkowski et al (2007).…”

“…The 5.3-mlong WZS/03 core was collected; a detailed lithological study as well as geochemical investigations carried out for WZS/03 core are presented by Rutkowski et al (2007). Lithological investigations of the core revealed several units, characteristic for post-glacial Polish lakes.…”

“…The coring location was in the deepest part (18.2 m water depth) of the southern part of the lake, in Slupianska Bay (Figure 1). The site was chosen based on previous seismic analysis (Figure lc,d;Rutkowski et al 2002b), which showed that the location was characterized by undisturbed sedimentation (Rutkowski et al 2007). …”

“…For the presentation and interpretation of results, the calendar timescale, as described in this work, is used, e.g. for lithology (Rutkowski et al 2007), pollen (Kupryjanowicz 2007), and Cladocera analysis (Zawisza and Szeroczynska 2007).…”

Oxygen stable isotope composition of carbonate encrustations of two modern, widely distributed, morphologically different charophyte species

“…In studies of lake sediments, oospores and encrustations, among other aquatic plant macrofossils, are useful indicators of past ecological conditions at the site of sediment deposition (Croft, 1952;Anadón et al, 2000;Becker et al, 2002;Rutkowski et al, 2007;Apolinarska et al, 2011). Therefore, analysis of plant macrofossils is commonly applied in paleolimnological reconstructions (Hannon & Gaillard, 1997;Bešta et al, 2009;Gałka & Apolinarska, 2014;Kowalewski et al, 2016).…”
