The article discusses the problem of excessive growth of one-year filamentous algae, contributing to the disturbance of ecological balance in the Puck Bay. The aim of the study is to estimate the possibility of restoring this balance through the use of macroalgae as a co-substrate for biogas and fertilizer production in the regional biological wastewater treatment plant (WWTP). Effectiveness of biogas production from aquatic plants, including free-floating filamentous algae, was examined. Tests have shown that the biogas potential of seaweed constitutes the level of 162 m3/Mg of organic dry solid substances of algae. It was estimated that using the summer intense algal growth, removing 65,000 Mg of algae, 800,000 m3 of biogas can be obtained from the area covering the inner Puck Bay. After biogas conversion, 2,320 MWh of electricity and 2,100 MWh of heat energy could be produced. Harvesting free-floating algae enables the annual removal of 100-150 Mg of phosphorus and 200-400 Mg of nitrogen from Puck Bay and, thus, reduces the level of its eutrophication. Macroalgae management at a certain stage of growth also prevents the presence of algae on beaches and contributes to the improvement of fishing conditions and boosts the tourism value of the region.

Among over 150 maps of sea surface temperature in the Polish Baltic coastal region derived from satellite data during the warm period of the year (April–October) in 2000–2002, 41 cases were noted where its distribution showed characteristic features indicating the occurrence of coastal upwelling. The fundamental parameters of range, probability of occurrence and temperature modification caused by water from deeper sea layers raised by an upwelling event and spreading across the surface were established for three regions (Hel, Łeba and Kołobrzeg). The Kołobrzeg upwelling region had the largest spatial range (up to 5000 km2). The region with the smallest spatial range (Hel, up to 1400 km2) had the largest surface temperature amplitude (to 14◦C), the largest maximum temperature gradient (5◦C km−1) and the largest average sea surface temperature decrease in the centre in relation to the background value.

The paper presents the results of studies of wave transformation on a multi-bar cross-shore profile of the southern Baltic Sea. The field investigations of wave motion were carried out using an offshore wave buoy and string wave gauges at the IBW PAN Coastal Research Station, Lubiatowo (Poland). These experimental results were used to validate statistical relationships between characteristic wave parameters in the coastal region and to assess wave energy dissipation in the surf zone. Asimple model for calculating the residual nearshore wave energy is proposed and tested versus the data collected in situ.

The projected effect of climate change is the increase of both the frequency and intensity of extreme weather events. An attempt has been made to study the extremes in temperature over two regions of India i.e. North-East Region (NER) and West Coast Region (WCR). A detailed analysis indicated that in the NER, ten stations indicate increase in annual extreme minimum but significant at four stations. Post-monsoon season is very predominant where five stations show significant increase. In the WCR, all the stations indicate increasing trend in annual extreme maximum temperature significant at nine stations. Majority of the stations indicate significant increasing trend in all the seasons except monsoon season.

New particle formation and growth were observed at a coastal site (Preila station, Lithuania) during 1997 and 2000–2002. The total amount of data analysed covers 291 one-day periods, 45 (15%) of which were long-term, new particle formation days. Short-term nucleation events (from a few minutes to one hour) and long-term events (from one to eight hours) were identified. The mean particle growth rate, condensation sink and condensable vapour source rate during nucleation events were 3.9 nm h−1, 1.45 × 10−3 cm−3 s−1 and 7.5 × 104 cm−3 s−1 respectively. The average formation rate J10 was 0.4 cm−3 s−1. The nucleation events were accompanied mainly by air masses transported from the north (43%) and north-west (19%). Meteorological parameters and trace gas (O3, SO2, NO2) concentrations were also analysed. It was found that nucleation events are related to high levels of solar radiation.

The main objective of this study was to determine the factors affecting the government supported bumble bees use as pollinators by greenhouse producers in the Mediterranean Coastal Region of Turkey. The data used in this study were collected from growers by using a face to face survey. To this end, data was obtained by using simple random sampling method in 80 greenhouse farms in Antalya province. The data were analyzed with the chi-square test which was used to test relationship between variables. The result of the analyses showed that there is a significant relationship between the farms using and non-using bumble bee, considering status registered for greenhouse of farmer, type of growing, type of greenhouse ventilation and the number of people working in greenhouse. Furthermore, the most of farmers believed that use of bumble bees as pollinators in greenhouse tomato production is beneficial. These benefits include the effect of environment and human health and also the economic (marketing, higher price, higher yield, reducing pesticide use and labor use).

The investigations were carried out on the common sea buckthorn (Hippohaë rhamnoides L.) growing in the coastal areas of the Baltic Sea. The performed analyses comprised the determination of the basic chemical composition and selected heavy metals. For comparative purposes, investigations were also conducted on wood of the common sea buckthorn growing in urban conditions, namely in the city of Poznań. On the basis of the performed experiments it was found that the content of cellulose in the examined material ranged from 33.6 to 39.3% with the highest values determined in the wood of bushes growing in urban conditions. In addition, considerable differences were also observed in the lignin content in the compared samples, whereas the concentration of pentosans remained at the level of 18% irrespective of the place of sample collection. Concentrations of the examined heavy metals did not exceed levels dangerous for the growth and development of the examined bushes.

The impact of transient wind events on an established zooplankton community was observed during a field survey in a coastal region off northern Norway in May 2002. A transient wind event induced a coastal jet/filament intrusion of warm, saline water into our survey area where a semi-permanent eddy was present. There was an abrupt change in zooplankton community structure within 4–7 days of the wind event, with a change in the size structure, an increase in lower size classes less than 1 mm in equivalent spherical diameter (ESD) and a decrease in larger size classes greater than 1.5 mm in ESD. The slope of zooplankton biovolume spectra changed from −0.6 to −0.8, consistent with the size shifting towards smaller size classes. This study shows that even well established zooplankton communities are susceptible to restructuring during transient wind events, and in particular when wind forcing induces horizontal currents or filaments.

The paper is an attempt to assess thermal conditions in the Dendrological Garden in Glinna against the conditions of the mesoregion of the Szczecin Coastal Region, as represented by five stations (Lipnik, Ostoja, Szczecin, Świnoujście, Kołobrzeg) in a study period of two years (May 2014- April 2016), based on measurements of air temperature taken at 200 cm a.g.l. Spatial variation of thermal conditions of the analysed area was found to be very large and was statistically confirmed. Mean air temperature in the analysed period in Glinna was 10.2°C which, in comparison with the other stations, proved to be the highest value. The absolute minimum, i.e. -12.7°C, was recorded in Glinna in January 2016 and the absolute maximum of 35.6°C in August 2015. It was shown that for the purpose of the assessment of thermal conditions in Glinna on the basis of mean air temperature from the 24-hour period, it is justified to refer to multiannual data from IMGW station in Szczecin. On the grounds of minimum temperature, amplitude, time of occurrence of spring and autumn frosts, as well as the number of days with frost and cold days, it was shown that the Dendrological Garden in Glinna has more favourable thermal conditions than the neighbouring areas.

This paper analyses wave attenuation in coastal mangrove forests in Vietnam. Data from 32 mangrove plots of six species located in 2 coastal regions are used for this study. In each plot, mangrove forest structures and wave height at different cross-shore distances are measured. Wave height closely relates to cross- shore distances. 92 exponential regression equations are highly significant with R2 >0.95 and P val. <0.001. Wave height reduction depends on initial wave height, cross-shore distances, and mangrove forest structures. This relationship is used to define minimum mangrove band width for coastal protection from waves in Vietnam.

Krüper’s Nuthatch (Sitta krueperi, Passeriformes) is small-area confined species and it mainly occurs in Anatolia in Turkey, but small numbers are found on the adjacent Lesvos Island and the Caucasus region. It is considered as a “near” threatened species by IUCN. Breeding success of Krüper’s Nuthatchs, which use nest cavities excavated by woodpeckers or make their own entrance holes in slightly decayed old tree trunks, is about 72% fledged birds and main food is composed of Coleoptera and Lepidoptera. Although this species is mainly confined to red pine (Pinus brutia) forest, it occurs also in the other coniferous habitats. Krüper’s Nuthatch was surveyed in four regions of Mediterranean Turkey: the Antalya, Central Taurus, Aladağlar region and Amanos Mountains on an area of 27.9 km². Total of 395 point counts were taken in coniferous forests during the breeding season 2005 to explore the factors which affect the population distribution and density. For each point counts following habitat parameters were measured: (1) height of canopy top, (2) height of canopy bottom, (3) tree diameter at breast height, (4) percentage cover (5) average distance between two trees, (6) total number of strata of vegetation and topographic data (altitude, degree of slope, direction of slope, soil texture). The average density of Krüper’s Nuthatch recorded in the all sites was 7.38 ± 0.57 birds km⁻². However, it differs between regions (ANOVA; P <0.0001) with highest density in the Antalya region (12.10 ± 2.10 birds km⁻²), and a decrease to the east with lowest density in the Amanos Mountains (2.42 ± 0.98 birds km⁻²). Krüper’s Nuthatch breeding density was higher in high altitude and in black pine (Pinus nigra) forest. The highest mean density was found in black pine forests (12.69 ±2.4 birds km⁻²; n = 29), followed by Cilician fir (Abies cilicica) forest (11.61 ± 2 birds km⁻²; n = 39), Lebanon cedar forest (Cedrus libani) (8.49 ± 1.8 birds km⁻²; n = 25) and red pine (Pinus burutia) forest (7.75 ± 0.9 birds km⁻²; n = 188) respectively. We also found a negative correlation between the densities of Krüper’s Nuthatch and the total number of strata of the vegetation. High number of the birds occurs in more open coniferous forests. Mature coniferous forests especially black pine forests at high altitudes should be preserved for its conservation in Antalya region.

The article presents problems of unemployment in the districts of the coastal gminas in West Pomerania Voievodship. The region is characterized by high touristic attraction and considerable volume of investment into touristic services. Besides rapidly developing areas, there are also agriculture districts characterized by the necessity to increase incomes of the inhabitants and improve the condition of infrastructure. The aim of the article is to answer the question: does tourism in its economic aspect stimulate economic performances and in consequence cause a considerable decrease of unemployment in the described region. Analysis includes differences of unemployment intensity and its structural factors that allow to identify the causes and also to define options and directions of further transformations.
