Berner cascade impactor was used to study urban aerosols in two localities of the Pomeranian macro-region Słupsk and Hel in autumn at different weather conditions. The range of aerodynamic diameters between 0.009 and 8.11 mm were separated. Elementary composition for each diameter was obtained in a complex procedure consisting of laser ablation of deposits then their successive ionization in inductively...
Estuaries are dynamic ecosystems characterized by great and constant variability of physicochemical gradients and biological parameters. Considerable fluctuations in salinity levels, temperature, pH, concentrations of oxygen, nutrients and organic matter are quite natural in such water bodies. There are many estuarine forms at the Polish Baltic Coast, including open-sea gulfs (the Gulf of Gdansk and...
A population of Hydrobia sp. (Hydrobia ulvae Pennant and Hydrobia ventrosa Montagu) was studied in the Polish coastal zone (up to 3 nautical miles) of the Baltic Sea within the open coast of Polish Middle Pomerania. Abundance, wet biomass, and the frequency of Hydrobia were determined in the coastal waters, including estuaries of the Wieprza, Słupia, Łupawa, Łeba rivers and open coastal in the vicinity...
Present population structure of Central Pomerania is a consequence of demographic transformations introduced in the post-war period. The population of the described region is heterogenic and has been combined by people who came from different parts of Poland, autochthons and generations born in this particular area. However the settlers from Central Poland (41.9%) and people who came from abroad (24...
The present publication describes a condition, way and level of tourist development and tourist movements of Rowy, a holiday resort. The analysis includes selected elements of tourist management such as accommodation, gastronomic and supplementary facilities. Size and frequency of tourist movements and social and demographic structures of tourists will be presented on the basis of measurements’ results...
Every year forest soils are enriched with nitrogen and phosphorus compounds due to the fall of leaves and litter of conifer needles, mineralization of ground cover and decaying tree roots, as well as precipitation. The process has been examined in two forest ecosystems: a mixed forest (plot I) and a young wood (plot II). The overall fall of duff collected in the young wood of the Słowinski National...
Research was carried out on the occurrence and physiological properties of heterotrophic bacteria inhabiting water of the River Brda in the Bydgoszcz town section. The highest number of microorganisms was found in water of the studied river in June and August at sites located in the centre of the town, and the lowest in November and March at the site located at the inflow of the river into the town...
Test was done on Arkonka underground water intake. To perform it, it was constructed the model station composed of the closed gravity filter, oxygen supply system, water supply system and a mixer. For needs of the experiment it was determined the iron reduction degree, manganese reduction degree, pH determination, determination of the oxygen contents in treated water. The above determinations were...
Tests were done on the model station situated on the territory of Szczecin–Pomorzany Water Treatment Plant. The tested water came from Kurowski Channel. Kurów is the river bank water intake from Kurowski Channel – an artificial arm of Western Odra River. Pumping station is situated 300 m far from the Kurowski Channel. Water is supplied to the intake chamber of the pumps using the pipeline 1400. Three...
The article presents the legal rules concerning the conduct of marine scientific research in Polish maritime areas by either Polish or the foreign researchers in the light of the international law and the relevant Polish national legislation. According to the 1982 United Nations Convention on the Law of the Sea the foreign researchers have to apply for an express consent of the respective Polish administrative...
Scanning electron microscopy was employed for the investigation of bacteria living on sand grains in a sandy marine beach in the Gulf of Gdansk (southern Baltic Sea). Bacteria colonize the sand grains; individual topography and shape of the grains were decisive for the colonization. Grains of diverse topography characterised by a great irregularity of shape were preferred, and protected surface sites...
This paper presents results of a field studies in ex-manor parks of Słowinskie Coast which were made during two vegetation seasons, from May2004 to September 2005. The studies covered six ex-manor parks located in the communes of Darłowo, Sianów, Ustka and Wicko. Two of them were entered into the register of monuments (Bukowo Morskie, Osieki Koszalinskie II) and four of them were in evidence (Gabino,...
