    Opis:
    The Durne Bagno peat bog is the eastern, peripheral part of a large marshland complex in the Lublin Polesie. Limnic biogenic deposits occurring directly on mineral deposits are up to 8.5 m thick. They exhibit great vertical facial variability and small lateral differentiation. This indicates that the conditions of sedimentation/sedentation were similar in the whole basin in particular time intervals. The chronostratigraphically-correlated sequence of sediments allows reconstruction of the geosystem evolution in recent 13 ka BP. In its entire Late Glacial and Holocene history two basic stages may be distinguished: lacustrine (OD — middle AT) and mire (middle AT — present time)

    Niemen River valley

    Opis:
    Based on geological and paleobotanic data, the oldest valley system of the Niemen River is linked in the study area with a river located southward of Grodno, within a parallel valley from the Alexandrian (Mazovian) Interglacial. The foundations of the present-day, almost meridian course of the Niemen River valley, are connected with a system of post-glacial lakes from the Sozhian (Wartanian) Stadial of the Pripethian (Odranian) Glaciation, later filled with organic deposits of the Muravian (Eemian) Interglacial. Analysis of six sites with these deposits (Pyszki, Rumlówka, Poniemuń, Żukiewicze, Bohatyrowicze and Kniażewodce) indicates that they represent three lakes located at different altitudes. During the maximal range of the Dvinian (Main) Stadial of the Poozerian (Vistulian) Glaciation, the lakes were beyond the range of the ice-sheet. At this time, the highest located deposits of the Poniemuń-Żukiewicze lake were covered by sander sediments, whereas the Bohatyrowicze-Kniażewodce and Pyszki-Rumlówka lakes that were located at lower levels, were covered by fluvio-periglacial deposits and varved clays of the Skidel ice-dammed lake. Retreat of the ice-sheet of the Dvinian Stadial, resulting in outflow of water from the Skidel ice-dammed lake through the area with the two lower interglacial lakes, triggered the formation of a system of the Niemen River supra-flood terraces above them. Accumulation of the highest of these terraces (VI), during the first phase of the Skidel lake outflow, marks the beginning of the present-day Niemen River valley formation that probably began in the younger phases of the Dvinian ice-sheet retreat. Further evolution of the valley is linked with the Late Glacial formation of the middle (III-V) supra-flood terraces and with the Holocene formation of the lower (II, I) supra-flood terraces.

    Opis:
    The most representative and long Late Pleistocene pollen sequences covering the late glacial of the penultimate glaciation (Warta/Pripiat), the last interglacial (Eemian/Muravian) and the early glacial of the Last Glaciation (Vistulian/Poozerie) from the territory of Poland and Belarus have been correlated. The resemblance ofpollen spectra in these pollen sequences and a parallel succession of Regional Pollen Assemblage Zones in the considered time intervals suggest that the natural environment of Poland and Belarus underwent synchronous changes under unidirectional climatic transformations. Qualitative and quantitative features of the Regional Pollen Assemblage Zones show similarities and differences in vegetation and climate changes in the study area. A comparison of the pollen spectra from Poland and Belarus suggests that both territories were affected by a similar climate particularly during the cold intervals. Some differences between the compositions of the pollen spectra were noticed as concerns the interglacial period. For instance, Abies and Taxus pollen as well as significantly high percentages of Calluna vulgaris pollen in NE Poland towards the end of the period are present only in the Polish sections. This may suggest a more Atlantic type of the climate during the Last Interglacial in Poland than in Belarus.

    Opis:
    Climate changes during the Pleistocene were driven by large-scale orbital perturbations as well as by internal feedbacks on the Earth. One of the main roles in climate modelling is played by the Southern Ocean that is a great source of sea ice, carbon dioxide, dissolved silica and nutrients. Numerous sediment and ice records derived from the Southern Ocean and Antarctica document high-resolution climatic changes that allow us a better understanding of global climate evolution. Consistently with the global climatic trend, several sea surface temperature (SST) records of the Southern Ocean are marked by a distinct shift from low to high glacial/interglacial variability around Termination V (T V), called the Mid-Brunhes Event (MBE). Prior to T V, the Southern Ocean’s SST displays lower values and low variability. It points to a distinct expansion of the Southern Ocean cold water masses and positional changes of hydrographical fronts during most of the lower Middle Pleistocene, which started in the Pliocene. Beside large climatic changes, several abrupt distinct warming and cooling phases have been recognized. Some of them (MIS 22–19, MIS 11 and MIS 5) show similarities to MIS 1, which could be used for future climate predictions. In this paper we would like to present the middle and late Pleistocene climatic mechanisms in the Southern Ocean, and to show SST changes in relation to the hydrographic frontal movement, sea ice development and CO2 oscillations.

    Opis:
    Quantitative analysis of radiolarian assemblages, carried out at the Ocean Drilling Program (ODP) Leg 177 Site 1091 (Atlantic sector of the Southern Ocean), provides a well-established summer sea surface temperature (SSST) record from the Polar Front Zone extending back into the Middle Pleistocene at orbital- -submillennial resolution. In order to estimate the SSST, the Imbrie & Kipp method (IKM) and the artificial neural network (ANN) were applied. The SSST records derived from the IKM and ANN display close similarities in paleotemperature fluctuations, amplitudes and absolute values. The ANN-derived SSST estimations display a pattern of slightly more distinct warm events that is closest to the records obtained from EDC (EPICA Dome C) ice cores and ODP Site 1090. The warm events indicate a distinct shift in the extent of the Southern Ocean cold water sphere that must have affected the ocean–atmosphere–ice field interactions and the configuration of high-latitude wind fields. Consistently with the global trend of paleotemperature fluctuation, the SSST record is marked by a distinct shift from low to high glacial/interglacial variability around Termination V. Prior to Termination V, the SSST displays coldest values and low variability. It points to a distinct expansion of the Southern Ocean cold water masses and positional changes of hydrographical fronts during most of the lower Middle Pleistocene.

    Opis:
    In the northern part of the Great Mazurian Lakes there is a post-lacustrine plain extending over 90 km 2 . This depression, called Skaliska Basin (Kondracki, 1998), is situated NE of Węgorzewo, overlapping the state boundary between Poland and Russian Kaliningrd Region (thus the northernmost part of the structure was not accessible for study). A glaciolacustrine lake existed there during Late Pleistocene (Pochocka-Szwarc & Lisicki 2001a, 2003). Defining the exact extent and direction of outflow from the Skaliska Lake are most important aims for palaeogeographic investigation of the area. For paleogeomorphological analyses of the Skaliska Basin, the following methods were used: Digital Terrain Model (1 : 200,000 scale), Landsat TM satellite images, archival cartographic materials, and results of geological investigations accompanying compilation of sheets Budry (Pochocka-Szwarc, Lisicki 2001a) and Banie Mazurskie (Pochocka-Szwarc 2003) of the Detailed Geological Map of Poland (1 : 50,000). The study allowed to recognize the lateral extension of the paleolake, and reconstruct the sequence of events that led to catastrophic out flow towards the NW.

    Opis:
    The Shelter above the Zegar Cave (Shelter No 388) (N 50°25’41” E 19°40’27”) is located in the Zegarowe Rocks ridge in the Ryczów Upland (southern part of the Czêstochowa Upland), municipalityWolbrom, district Olkusz. In 2009, Mrs. Jadwiga and Mr. Lucjan Wodarz found an archeological flint artifact in a type of leaf point at the slope below the Shelter. This finding allowed suspecting the presence of Palaeolithic cultural layers inside or near the Shelter. The authors’aim was to recognize the geological context of the Palaeolithic settlement of the Shelter above the Zegar Cave and its neighborhood, and in further perspective of the entire southern part of the Ryczów Upland micro-region. Four layers were discovered in the Shelter during field works (downward): I – humic silty loam, Holocene; II – loess altered by secondary soil processes during the Holocene; III – unaltered loess, dated to MOIS 2; IV – silty cave loam with limestone rubble, dated to MOIS 3. The chronostratigraphy is based on lithostratigraphy and confirmed by radiocarbon and thermoluminescence dating. An archaeological cultural level occurs in layer IV, most probably related to the shift from the Middle to Upper Palaeolithic. The sequence of cave sediments may be well correlated with numerous profiles of cave sites from the Kraków-Czêstochowa Upland.
