Water circulation and recharge pathways of coastal lakes along the southern Baltic Sea in northern Poland

Abstract The purpose of this paper is to describe water circulation patterns for selected lakes found along the Baltic coast in northern Poland and to determine primary recharge mechanisms or pathways that produce an influx or loss of lake water. A secondary purpose of the paper is to determine the magnitude of recharge for each studied source of water – river water influx, surface runoff from direct catchments, forced influx from polders surrounding lakes, and periodic marine water intrusions from the nearby Baltic Sea. It is also important to determine the magnitude of water outflow from lakes to the sea via existing linkages as well as to compare horizontal influx and outflow data. The study area consisted of five lakes located along the Baltic Sea in northern Poland: Łebsko, Gardno, Bukowo, Kopań, Resko Przymorskie. The main driving force of the studied lakes are large rivers that drain lake catchment areas and periodic brackish water intrusions by the Baltic Sea.

The purpose of the essay was analysis and evaluation of the load generated by pollutants in the Russian part of the catchment area directly entering the Baltic Sea, as well as consideration of pro-rata contribution of all sources in the formation of factual biogenous load at the catchment areas of rivers flowing into the Gulf of Finland.The assessment of biogenous load was made on the basis of observation data, statistical reporting data, mathematical modelling data and additional monitoring data for bodies of water in previously uncontrolled areas. To assess the amount of biogenous input from uncontrolled tributaries of the Gulf of Finland, field observations of the discharge and concentration of pollutants over a number of past years were analyzed and generalized.It is noted that there has been a tendency towards reduction of pollutants for a number of substances in the last decade, as shown by the analysis. It is demonstrated that a significant decrease is due to reduced load from point sources that discharge pollutants directly to the Baltic Sea and its bays. Some proposals are presented for improving the Russian system of monitoring the load exerted on water bodies.

AbstractIn the study, archive data on the maximum annual ice extent in the Baltic Sea (MIB) for the period 1961–2018 were used. They were obtained from the FIMR database. Data on ice parameters for the four largest southern Baltic coastal lakes: Jamno, Bukowo, Gardno and Łebsko, and for Szczecin, Puck, and Vistula Lagoons, come from the Maritime Branch of Institute of Meteorology and Water Management – National Research Institute (in Polish: Instytut Meteorologii i Gospodarki Wodnej – Panstwowy Instytut Badawczy, IMGW-PIB) in Gdynia. The time series for the lakes cover the years from 1960 to 2018, and for the lagoons – from 1946 to 2018. Three ice parameters were selected for this study: the number of days with ice, the duration of the ice season and the maximum ice thickness for a given winter. Relationships between the selected ice parameters for the studied basins and the MIB were examined using correlation and regression methods.Correlations between the MIB and values of the ice parameters for the lakes and the southern Baltic coastal lagoons do not differ significantly. Considerable differences are observed amongst the correlation coefficients for individual ice parameters and the MIB.Larger differences are found in relationships between the values of individual ice parameters in the sheltered basins and the MIB. The strongest correlation with the MIB is observed for the maximum ice thickness and the number of days with ice.

Abstract Although airports play an important role the global and European economies, according to the new guidelines of the EU Commission on the new state aid rules for a competitive aviation industry (EC, 2014), it will be more difficult for unprofitable airports, to get financial public subsidies in the future. The Commission noted that the majority of regional airports experience severe problems to cover their operative costs, resulting from among other things from overlapping of airports’ catchment areas. The main objective of the above mentioned measures is not to close the regional airports, but to motivate them to operate on cost efficient, profitable and more flexible basis, stating however that and that the most inefficient airports will be still closed. In order face upcoming challenges, the regional airports shall reconsider their future development plans. Traditionally, the airports including small and regional airports focus on the passenger traffic and thus, the possible benefits and opportunities of the air cargo market are totally underestimated or even completely ignored. Most regional airports in the Baltic Sea region act totally isolated and do not have a clear picture of the current situation on the international air cargo market today, its future perspectives and sustainable development plans remain basically hidden. There are some examples when trying to meet the market demand, the regional airports have made huge, but unfortunately unjustified investments, e.g. improving airport infrastructure, runways, etc. However, the airports’ infrastructural investments alone cannot fulfil the expected “remedy” role for the airports’ sustainability. This paper aims at investigating the positioning and the role of the regional airports in the current hub-and-spoke network, focusing on the relevance and potential of the air cargo sector for the regional airports development. The optional freight value proposition for the development of the regional airports and their possible participation in the air cargo market as a supplement instrument to generate additional revenue also by means of so-called “air trucking” services will be presented and discussed.

ABSTRACT Heterotrophic bacteria are important drivers of nitrogen (N) cycling and the processing of dissolved organic matter (DOM). Projected increases in precipitation will potentially cause increased loads of riverine DOM to the Baltic Sea and likely affect the composition and function of bacterioplankton communities. To investigate this, the effects of riverine DOM from two different catchment areas (agricultural and forest) on natural bacterioplankton assemblages from two contrasting sites in the Baltic Sea were examined. Two microcosm experiments were carried out, where the community composition (16S rRNA gene sequencing), the composition of a suite of N-cycling genes (metagenomics) and the abundance and transcription of ammonia monooxygenase (amoA) genes involved in nitrification (quantitative PCR) were investigated. The river water treatments evoked a significant response in bacterial growth, but the effects on overall community composition and the representation of N-cycling genes were limited. Instead, treatment effects were reflected in the prevalence of specific taxonomic families, specific N-related functions and in the transcription of amoA genes. The study suggests that bacterioplankton responses to changes in the DOM pool are constrained to part of the bacterial community, whereas most taxa remain relatively unaffected.

Abstract Strehlow, H. V. 2010. The multiannual management plan for cod in the Baltic Sea: reactions and sentiments in two German fishing communities. – ICES Journal of Marine Science, 67: 1963–1971. Just before and one and a half years after the implementation of the Multiannual Management Plan for the Cod Stocks in the Baltic Sea, the same two fishing communities on the German Baltic coast were visited to try to understand the impacts of the plan. Such information is a prerequisite for policy-makers to mitigate possible negative consequences on specific fleet sectors. During semi-structured interviews, observations, and group discussions, information on the reactions and the sentiments about the plan prevailing in the communities was collected. In general, the plan found widespread approval, because it improved planning reliability for fishers and cooperatives considerably. Conversely, the reduction in fishing effort stipulated in the plan has had strong adverse effects on small-scale fishers. The survey furthermore revealed that this fishery segment using passive fishing gear is among the most vulnerable, because it is the interest group with the lowest income, little resilience to cope with further restrictions, and no lobby to improve their position.

Abstract The Wicie ringing station was one of several stations which cooperate within the SEEN organization (SE European Bird Migration Network). The station was located west of the small village of Wicie located in northern Poland on the central part of the Baltic Sea coast. The station was situated on a narrow spit between Kopañ Lake and the Baltic Sea and has operated since 2010. Data were collected during three spring and five autumn seasons. Birds were caught in mist-nets, which were placed mainly in bushes and reed beds. Over 55 000 birds of 113 species were caught and ringed during eight migratory seasons. Many of them were also tested for directional preferences in Busse’s cages.

Baltic Seaports are a part of the sustainable global transport infrastructure. The main competitors of the Baltic countries in Baltic Sea region are the ports of Lithuania, Latvia, and Estonia. The ports of all three Baltic States are important transit corridors, connecting not only East and West, but also South and North. Periodical investments, modernization, and the construction of new terminals allow the Port of Klaipeda to successfully compete with neighbouring ports and strive for leadership positions. Thus, the aim of our study is to investigate the competitive environment of the Baltic Sea region. We use systematization, grouping, summarization of the scientific literature, data collection, comparison, financial analysis, and capacity calculation. The main results show that the Port of Klaipeda, a seaport on the eastern Baltic coast, is an important hub of the East-West (IXB) transport corridor, connecting roads and sea routes in this direction. With the accession of new members, including Lithuania, to the EU in 2004, the Baltic Sea became the internal Sea of the Union. Many Baltic seaports belong to the same system and organizations (ESPO, BPO). EU ports policy provides them with equal requirements for security, transport regulation, environmental protection, anti-air pollution, and sustainable development. The results obtained enable exploration perspectives. This includes a feasibility study for port development and attracting new investment from foreign capital markets in the Baltic Sea region.
