Changes in habitat conditions in a Late Glacial fluviogenic lake in response to climatic fluctuations (Warta River valley, central Poland)

Jacek Forysiak, Daniel Okupny, Milena Obremska, Olga Antczak-Orlewska, more

Geological Quarterly > 2023 > Vol. 67, No. 1 > art. no. 1

The Warta River valley was greatly influenced by the ice sheet of the Last Glacial Maximum (LGM). A small peatland located in the Warta drainage system is here used as a palaeoarchive of climatic and habitat changes during the Late Glacial (Weichselian). The Ługi sediment profile was investigated using multi-proxy (pollen, Chironomidae, Cladocera and geochemistry) analyses that recorded changes in...

Geochemistry of a sedimentary section at the Wąwelnica archaeological site, Szczecin Hills (Western Pomerania)

Daniel Okupny, Ryszard K. Borówka, Bernard Cedro, Joanna Sławińska, more

Acta Geographica Lodziensia > 2020 > 110 > 169-186

The results of geochemical assays on biogenic sediments filling a fossil lacustrine basin at Wąwelnica, in the Szczecin Hills, within the left-bank part of the Oder River catchment are presented. The data reveal a natural Holocene sedimentation sequence similar to that found for other sites in central Europe. The geochemical record of palaeo-environmental changes, which may be a consequence of human...

Lithology and geochemistry of the Late Glacial and Holocene sediments from Gostyń Lake (Western Pomerania, Myślibórz Lakeland)

Andrzej Korzeniowski, Daniel Okupny, Adam Michczyński, Joanna Sławińska, more

Acta Geographica Lodziensia > 2020 > 110 > 149-168

Sediment geochemistry and lithology were studied in Gostyń Lake in the eastern part of the Myślibórz Lakeland (part of the Western Pomeranian Lake District). The research was undertaken because relatively shallow lake basins without ground supply contribute to the intensification of water circulation through evaporation. Late Glacial and Holocene phases in the evolution of Gostyń Lake were reconstructed...

Geology, stratigraphy and palaeoenvironmental evolution of the Stephanorhinus kirchbergensis‐bearing Quaternary palaeolake(s) of Gorzów Wielkopolski (NW Poland, Central Europe)

Artur Sobczyk, Ryszard K. Borówka, Janusz Badura, Renata Stachowicz‐Rybka, more

Journal of Quaternary Science > 35 > 4 > 539 - 558

The sedimentary succession exposed in the Gorzów Wielkopolski area includes Eemian Interglacial (MIS 5e) or Early Weichselian (MIS 5d–e) deposits. The sedimentary sequence has been the object of intense interdisciplinary study, which has resulted in the identification of at least two palaeolake horizons. Both yielded fossil remains of large mammals, alongside pollen and plant macrofossils. All these...

The response of flood-plain ecosystems to the Late Glacial and Early Holocene hydrological changes: A case study from a small Central European river valley

Dominik Pawłowski, Ryszard K. Borówka, Grzegorz Kowalewski, Tomi P. Luoto, more

CATENA > 2016 > 147 > C > 411-428

We use a range of environmental variables to explore the possible drivers influencing the biota, especially the composition of aquatic invertebrates, during the Younger Dryas (YD) and Early Holocene (EH) in different river valley sites: a well-developed meandering river and the confluence zone of headwater streams. Using pollen, macrofossil, cladoceran, and chironomid as well as geochemical and lithological...

Late Weichselian and Holocene record of the paleoenvironmental changes in a small river valley in Central Poland

Dominik Pawłowski, Ryszard K. Borówka, Grzegorz A. Kowalewski, Tomi P. Luoto, more

Quaternary Science Reviews > 2016 > 135 > C > 24-40

The developmental history, from the Oldest Dryas to the Late Holocene, of a paleolake and mire located in a river valley in Central Poland was studied using high-resolution records of pollen, macrofossils, Cladocera, sedimentology, and geochemistry from a ¹⁴C dated sediment core. We inferred temperature and water level dynamics using cladocerans and palynological and geochemical methods were employed...

article

Early Holocene hydrology and environments of the Ner River (Poland)

Piotr Kittel, Mateusz Płóciennik, Ryszard K. Borówka, Daniel Okupny, more

Quaternary Research > 2016 > 85 > 2 > 187-203

The Ner River valley (central Poland) underwent substantial transformation during the Weichselian–Holocene transition as a result of fluvial processes and climate changes, resulting in the establishment of its present shape in the Holocene. A multiproxy study based on organic deposits from a palaeochannel fill (Lutomiersk–Koziówki) shows that after the channel was cut off during the late glacial termination,...

Fen ecosystem responses to water‐level fluctuations during the early and middle Holocene in central Europe: a case study from Wilczków, Poland

Mateusz Płóciennik, Andrzej Kruk, Jacek Forysiak, Dominik Pawłowski, more

Boreas > 44 > 4 > 721 - 740

This paper presents a palaeoenvironmental reconstruction of the Wilczków fen (central Poland). The fen developed in an inactive valley at the onset of the Holocene (~11 ka BP) and peat accumulation lasted until 5.7 ka BP. Multi‐proxy reconstructions were made on the basis of palaeobotanical, cladoceran, chironomid, beetle and geochemical analyses. A Kohonen self‐organizing map (SOM, unsupervised artificial...

Stable isotope composition of subfossil Cerastoderma glaucum shells from the Szczecin Bay brackish deposits and its palaeogeographical implications (South Baltic Coast, Poland)

Ryszard K. Borówka, Wacław Strobel, Stanisław Hałas

Quaternary Research > 2012 > 77 > 2 > 245-250

The environmental conditions of the Szczecin Bay, which existed prior to Szczecin Lagoon, have been reconstructed on the basis of the stable carbon and oxygen isotope ( ¹⁸ O and ¹³ C) analysis and radiocarbon dates obtained for subfossil shells of Cerastoderma (Cardium) glaucum. The shells in the collected core were well preserved in their life positions, representing a geochemical...

Holocene marine ingressions in the coastal zone of the pomeranian bay based on radiocarbon assays

Ryszard K. Borówka, Bernard Cedro

Geochronometria > 2011 > 38 > 1 > 85-92

In recent years, a team at the Geology and Paleogeography Unit, Marine Sciences Institute, University of Szczecin, has been performing geological, geochronological and paleogeographic surveys in (i) the Szczecin Lagoon and Świna Gate Sandbar and (ii) the estuary section of the Rega river valley near Mrzeżyno. These studies have helped to examine and identify not only the distribution of fossil marine...

Late Glacial and Holocene depositional history in the eastern part of the Szczecin Lagoon (Great Lagoon) basin-NW Poland

Ryszard K. Borówka, Andrzej Osadczuk, Andrzej Witkowski, Brygida Wawrzyniak-Wydrowska, more

Quaternary International > 2005 > 130 > 1 > 87-96

Analyses on 27 sediment cores taken from the bottom of the Szczecin Lagoon allowed environmental reconstruction of the postglacial main stages of basin development, based on detailed sedimentological, geochemical, diatomological and malacological studies of selected key cores. Studies revealed that during the Late Glacial and Holocene this area developed in several stages. In the Late Glacial the...
