Opis:: This paper summarizes four years of geological research in the Pomerania Bay and Oder Bank. As a result of the synthesis of new and archival data,we have compiled maps, cross-sections and models depicting the geological structure of the Quaternary and its basement, and the relief of structural surfaces. Two main seismostratigraphic sedimentary complexes are distinguished. The first corresponds to Pleistocene glacial and interstadial deposits. The second one is composed of Late Glacial and Holocene lacustrine-swamp and marine sediments. The outline of geochemical condition of the sea bottom is also presented. The content of the elements is always below the acceptable concentration and the origin of the elements is geogenic. Special attention has been given to mineral resources on the bottom surface and to documenting deposits of sand containing heavy minerals. The characterization of areas with sands suitable for beach nourishment and valorization of deposits and prospective areas have also been of great importance. The history of the development of the geological structure and palaeogeography of the area is the summary of the results.

Opis:: The purpose of this study is to reconstruct the temperature conditions in the sediment during the diagenesis history of Pennsylvanian sandstones drilled in three deep boreholes in the Baltic Sea. These sandstones are represented by quartz and sublithic arenites and wackes, cemented by matrix and autigenic minerals. Among the autigenic minerals: quartz, clay minerals (kaolinite, dickite, illite) and carbonates (calcite, dolomite, ankerite) are the temperature indicators. The presence of dickite in the sediments indicates a temperature of about 120°C. Quartz and carbonate crystallization temperatures, based on the analysis of fluid inclusions, are estimated to be in the range of 70-180°C. The K/Ar age of the fibrous illite thatforms at the final stage of diagenesis (above 100° C), was determined at 262 ±2 to 247 ±4 My, i.e. from the Middle Permian to the Early Triassic. It determines a length of the post-deposition period, when the deposits were permeable for pore fluids.

Opis:: The climate changes and related crucial environmental changes in the Late Glacial and Holocene in the Southern Baltic area can be investigated by mollusc and ostracod analyses. It is well known that accumulation of mineral and biogenic sediments in the Southern Baltic area began in the Late Glacial. The process took place in cold tundra lakes and mires. The presence of lake basins is confirmed by seismoacoustic investigations and the resulting 3D spatial model. Lacustrine sediments contain an assemblage of molluscs and ostracod fauna represented by freshwater species indicating cold climate, such as: Armiger crista f. cristatus, Gyraulus laevis, Lymnaea peregra, Pisidium casertanum, Pisidium casertanum f. ponderosa, Pisidium milium, Pisidium nitidum, Pisidium obtusale f. lapponicum, Valvata cristata, Pisidium conventus, Candona candida, Candona neglecta, Cytherissa lacustris, Darwinula stevensoni and Cypridopsis vidua. The accumulation in freshwater reservoirs was continued during the Early Holocene. Besides cold freshwater species, sediments of that age also contain freshwater species of molluscs and ostracods that required higher temperature: Bithynia tentaculata, Physa fontinalis, Pisidium amnicum, Candona compressa and Metacypris cordata. It indicates a climate warming in the Preboreal period. These lake sediments were partly destroyed and covered by marine sands during the Middle and Upper Holocene. Good indicators of changing from a freshwater to marine environment are the following marine species found in the sediments: Hydrobia ulvae, Hydrobia ventrosa, Cerastoderma glaucum, Mytilus edulis, Macoma balthica, Cyprideis torosa and Cytheromorpha fuscata.

Opis:: During transportfrom the field to the sea nitrogen undergoes natural reduction resulted mainly from denitrification, but with large spatial variations. In the present study, a map for spatially variable nitrate reduction in groundwater in the area of Poland is presented. The map was preparing following 3 steps: (i) identification of major hydrogeological units (Lowland and Mountain-Upland Provinces); (ii) identification of dominating lithology with use lithotypes classifications from Groundwater Vulnerability Map of Poland in scale 1 : 500 000; (iii) estimation of the influence of artificial drainage. The resulted distribution of nitrate reduction coefficient reveals a distinct bimodality related to the sharp contrast in hydrogeology between the two provinces.

Opis:: The paper presents results of SPINUA (Stable Point Interferometry over Unurbanised Areas) Persistent Scatterers Interferometry (PSI) processing chain to study Earth surface deformations along the SW coast of the Gulf of Gdańsk, along the SE part of the Baltic Sea. As the input for SPINUA techniques 40 descending ERS-1/2 SLC (Frame = 251, Track = 36) images from the period 1995-2001 has been used. The area of interest (AOI) includes few cities and several towns, villages and harbors. The low lying coastal areas of the SW part of the Gulf of Gdańsk are at risk of floods and marine erosion. The PSI results, however, did not reveal the presence of a regional scale, spatially consistent pattern of displacements. It is likely that any crustal deformations in the AOI simply do not exceed +2 mm/year, which is the velocity threshold we assumed to distinguish between moving and non-moving persistent scatterers (PS). Importantly, for the most part the urban areas of the main cities (Gdańsk, Gdynia and Sopot) results show ground stability. Nevertheless, significant downward movements up to several mm/year, are locally noticed in the Vistula river delta - alluvial plain system located in the coastal zone east of Gdańsk as well as in the inland area west of the Gdańsk city. Indeed, the highest subsidence rates (-12 mm/year) was observed in the Gdańsk petroleum refinery constructed on alluvial sediments. Thus the anthropogenic loading and consolidation of the recent deposits can locally be an important factor causing ground subsidence.

Opis:: The research task Geological integrated coastal zone mapping concerns the recognition and visualization of the geological structure of the Polish coastal zone, enriched with the modelling of erosion-accumulation processes, including prediction of changes in the position of the shoreline and identification of geohazards. It has been running since 2012 and implements multi-instrumental research methods. To date, a total length of about 155 km of the Polish coastal zone has been studied in an area of about 621 km 2 . The main results of the work are presented in the form of maps (e.g., lithogenetic, hydrogeological, geohazard), models (e.g., morpho-geological, hydrodynamic, predictive) and specialized analyses (e.g., morphodynamical, slope stability). In general, the work carried out is done for a utilitarian purpose, i.e. aimed at the practical use of environmental information. According to the standards of the Polish Geological Survey, most of the geological data acquired can be geoprocessed.

Opis:: Authors analyze the resistance of shear and compression of the Polish Baltic soils on the depth of 10 and 20 m below the sea bottom. On the basis of selected mechanical properties of the Polish Baltic soils have been characterized the devided geological-engineering units on the depth of 10 and 20 m below the sea bottom. These characteristics concern the engineering- geological division of the sea bottom are founded on the detailed analyses of the geological maps of the Baltic Sea bottom in scale of 1: 200 000 and on the geological interpretation of seismoacoustic investigations which were executed in selected parts of the area of the Baltic Sea and also on the base of the results of detailed engineering-geological research of some fragments of the sea bottom and the coastal zone in the area of western Pomerania. On this base, the authors present the engineering-geological units of the Polish Baltic soils on the depth of 10 and 20 m below the sea bottom. There were taken into account certain geological criteria such as a lithological type, genesis and age of deposits and also geotechnical criteria beside of resistane of shear (f) and resistance of compression (Rc), the next properties such as a index of density (ID ), index of liquidity (IL ), angle of internal friction (), cohesion (c).

Opis:: Fresh water accumulated beneath the sea floor may flow through sediments into the sea water. This process, opposite to infiltration, is called Submarine Groundwater Discharge (SGD). The Southern Baltic Sea coastal zone represents an interesting object of study because its bottom deposits show seepages of fresh groundwater. The study involved Puck Bay and the adjacent coastal belt of the Kashubian Coast plateau. Research of potential outflows of fresh groundwater was done through a thermal imaging of the study area. An articulate thermal anomaly allowed predetermining the location of research points. Groundwater outflows in the seabed were confirmed by measurements of chloride content and electrical conductivity of water samples. The paper presents two new devices: a filtrometer that enables measurement of water filtration intensity during drainage, and a gradientmeter that measures the hydraulic gradient. The use of both devices allows determination of the in situ hydraulic conductivity. Results of the research have shown relationships between fresh groundwater and the sea-bottom sediments.

Opis:: Studies on Baltic nodules have been undertaken since the1920s. In the 1970sand 1980s, the Polish Geological Institute - National Research Institute conducted researches on the bottom sediments of the Baltic Sea, which allowed identifying the regions of occurrence of Fe-Mn nodules in the southern part of the Baltic Sea (Mojski, 1989-1994). Nodules from the Polish Baltic Sea Zone are the least studied element of the marine environment. So far, there is a lack of information on environmental-geological conditions of formation and occurrence of nodules, their metal resources and deposit potential. The Fe-Mn nodules may be a valuable source of information on the contamination of the Baltic Sea water and bottom sediments. In cooperation between the Institute of Oceanography of the University ofGdañsk and the Polish Geological Institute-NRI, two research cruises were carried out in August and September 2020 on a 5 X 5 km testing ground in the Gotland-Gdańsk Threshold region. The seabed surface was profiled using multibeam echo sounders and a side-scan sonar. A hundred samples of Fe-Mn nodules, 25 samples of surface sediments associated with the nodules, and25 samples of clay rocks underlain by marine sediments were collected. The extensive documentary material will enable, for the first time, to estimate the nodule resources and determine the regularity of their occurrence.

Opis:: The article is an overview of 50 years of Marine Geology Branch (MBG) activity in the field of geological cartography in Polish maritime areas. As a result of successive recognition of the geological structure of the Cenozoic, sheets of the Geological Map of the Baltic Sea Bottom at a scale of1 : 200,000 had been published by 1994, followed by a geological map without Quaternary deposits. The summary of the stage of over 25 years of intense research was the Geological Atlas of the Southern Baltic. The achievements of the Marine Geology Branch also include geochemical atlases, geo-environmental maps, and coastal zone maps created on the basis of detailed mapping works. The successively expanded geological database enables the creation of many map products for the needs of specific users. Various studies related to marine geological cartography, and extensive national and international cooperation have significantly contributed to the development of the scientific staff of the Marine Geology Branch.

Opis:: The accomplishment of the vision of exploration and in particular of exploitation of shale oil and shale gas in a perspective of a few years’time seems to be unrealistic. Interest in unconventional deposits occurs amongst small entities seeking a satisfactory return on their investments and becoming pioneers like George P. Mitchell 40 years ago. It is not only a result of high costs or lack of a sufficient technology but most notably the result of lack of an involvement of the key players in the global market. European companies, for instance, are closer to exploration of the new shale gas deposits onshore, although some of them declare to make an offshore research too. While Poland is today’s leader of shale gas exploration on the continent, it is also facing a problem of the lack of appropriate technologies of working at sea and country’s shales in general. In addition, the potential resources from the Baltic Sea bed, belonging to the Lower Paleozoic formations (Ordovician–Silurian) in the Baltic Basin, characterized by a good performance and shallower location than onshore deposits, are over four times more expensive to explore than on the land, which causes that there is no reason for recognizing them as economically recoverable resources. Therefore, any exploration of gas and oil from unconventional deposits in the Baltic Sea will have no economic justification within the next few years, but should only be considered as research.

Opis:: This paper presents structural data and regional correlations based on drill cores from 8 boreholes (B2-1/80, B3-1/81, B4-1/81, B6-1/82, B6-2/85, B7-1/91, B16-1/85 and B21-1/95) penetrating Precambrian crystalline rocks in the Polish part of the Baltic Sea. The crystalline rocks from the ftom these boreholes were compared to cores from several wells in Eastern Pomerania, and the Kashubian and Warmia regions and above all with the Mesoproterozoic granitoids and metamorphic rocks of Bornholm and Southern Sweden. The pre-existing basement map of the Southern Baltic, showing Palaeoproterozoic or even Archaean granitoid massifs and narrow north-south fold belts is questioned. Instead, in the present interpretation, the studied area of the Polish part of the Southern Baltic Sea is underlain by a fragment of the Mesoproterozoic (ca. 1.47–1.43 Ga) Danopolonian („Hallandian”) orogeny, comprising mainly regional-scale ductile shear zones, which, striking probably in W–E to WNW–ESE directions, are characterized by the predominance of a thrust to transpressional strain regime with tectonic transport top-to-the S or SSW. The structural kinematic and lithological interpretations of these shear zones are based on comparison with the other parts of the East European Craton that are exposed in Bornholm and the Blekinge and Skne regions in Southern Sweden.

Opis:: The paper presents comprehensive results of the hydrogeochemical and isotope analysis of waters in terms of their genesis and “ages”. Mostly chloride anomalies were found on the Polish Baltic coast. The processes of ascension and ingression of saline and brackish waters are the main reasons for their development. The water exchange rate was determined in each aquifer systems within the study area the results of isotope analysis, the concentrations of 4He and 3H. A significant contribution of infiltrating waters in cold climate is apparent in samples taken from: Ustka, Jarosławiec and Dąbki, for which NGT values range from 4.3 to 5.2°C. Waters with this genesis are found mainly in deep Pleistocene aquifers and Cretaceous roof layers. Changes in the chemical composition of waters in this area are strongly affected by human activity consisting in excessive exploitation of aquifers (mainly in the 1970s and 1980s). The process of saline water penetration into exploited aquifers was most extensive at that time. At present, it has been significantly inhibited as a result of reduced water extraction at the water intakes in this area. New water intakes are located at a considerable distance from the areas threatened with ingression or ascension of brine and saline water.

Opis:: The Orłowo Cliff is built of glacial and fluvioglacial deposits, Middle Polish Glaciations (possibly Odranian and Warthanian) and Vistulian Glaciation. Deposits are heavily deformed glaciotectonically. In the northern part of the cliff, Miocene sediments are exposed. It is possible, that the Miocene sediments were dislo-cated from their primary position. There were observed overthrusts and intermingling with Pleistocene material in the lower part of the exposure. The Orłowo Headland is built of glacial tills. It is probably a part of fold, similar in pattern to the structure of overthrust folds present in silty-sandy-grained deposits in the southern part of the cliff. Apart from folds and overthrusts there are many faults and the boudinage. Structural analysis of glaciotectonic deformations in conjunction with origin of deposits and statigraphic research enabled the recognition of several stages of development of deformations. Two local directions of glaciotectonic transport were marked clearly: from the north-east, which was connected with glacier invasion in the OEwiecie Stadial of the Vistulian Glaciation, and direction from north-west (north north-west), related to the Main Stadial of the Vistulian Glaciation.

Opis:: The paper presents the characteristics of prospective zones identified for the first time within the lower Palaeozoic shale formations occurring in the Baltic-Podlasie-Lublin Basin and within the Carboniferous shale, sandstone, and mixed shale-sandstone complexes (the so-called hybrid complexes) in the basin of south-western Poland. The lateral and vertical ranges of these zones are determined based on specific criteria using the results of various research methods and analyses, i.e.: stratigraphic, sedimentological, mineralogical, petrological and geochemical of organic matter, petrographic and petrophysical, including interpretation of well logs. Archived geological materials and those coming from the boreholes drilled recently in the concession areas were also used. Four prospective zones have been distinguished in the lower Palaeozoic of the so-called shale belt: SP1, SP2, SP3 and SP4. The most prospective area for the occurrence of unconventional hydrocarbon deposits in shale formations is the Baltic region – the Łeba Elevation, where there are all four perspective zones, only partially covering the range of potentially prospective formations. In each of these zones, both liquid and gas hydrocarbons can be expected in this area. Due to the low percentage of organic matter, the lowest hydrocarbon generation potential is attributed to the Lublin region. However, the low values of this parameter are compensated by other parameters, i.e. the considerable thickness and lateral extent of zone SP4 corresponding partly to the Pelplin Formation. In the Carboniferous rocks of south-western Poland, seven prospective zones have been distinguished in four borehole sections. Four of them are “tight” zones in compact sandstones, while the other three zones represent a hybrid type in complexes with mixed lithology. No prospective zones have been defined in complexes with homogeneous shale lithologies. Determination of lateral extents of the identified zones has not been possible due to the scarcity of data on the geological structure and stratigraphy of the Carboniferous succession in the study area
