Ochrona wysokich torfowisk bałtyckich na Pomorzu

The purpose of the study: The purpose of the study is to assess the regional potential of the territory enriched with peat resources and to develop strategic directions and mechanisms aimed at its further sustainable and competitive development.
The methodology: Methodology is based on a systematic analysis of socio-economic processes, the use of monographic studies, the use of abstract-logical, economic-statistical, computational-constructive, and expert research methods. The object of the research is the production and social infrastructure of out-of-town territories. The subject of the research is to identify patterns, trends, and features of the formation and functioning of the industrial and social infrastructure of the out-of-town territory.
Main findings: The use of new technological processes and equipment for the processing of peat and mineral raw materials was substantiated scientifically to obtain new composite materials for multipurpose applications. The features of the use of local peat resources in ensuring the development of out-of-town territories were investigated based on a set of scientific approaches. The feasibility and effectiveness of the application of project management for the natural and technogenic complex to ensure multi-criteria optimization of the production and social infrastructure were established.
Applications of this study: The results of this study were tested and implemented within the territory of the Khanty-Mansiysk Autonomous Okrug-Yugra, which made it possible to develop a strategy for the development of a cluster-type okrug and increase the efficiency of using local peat resources of extra-urban areas.
The novelty (originality) of this study lies in the fact that the conducted research enabled to identify new features of the use of local peat resources in ensuring sustainable development of out-of-town territories, and to develop a strategy of socio-economic development adequate to new challenges of the external environment.

Peatbogs are important in global greenhouse gas budget estimates. The main aim of the work was to assess the amount of greenhouse gas emissions based on the Greenhouse Gas Emission Site Type (GEST) method and compare them with actual field measurements. The research was carried out in selected peatbog areas in the coastal zone of northern Poland. The proposed method allowed us to assess whether the restoration treatments carried out in peatbogs contributed to the emission of these gases. The results of this research using the GEST method indicate that, in the studied peatbog areas, the reduction in CO2 emissions was approximately 12%. These results were compared with actual measurements of greenhouse gas emissions made using the chamber method in 2018. The average CO2 emission for the entire peatbog was 16,338.7 t CO2-eq./yr. Comparing this result with the result obtained using the GEST method, it should be stated that it is lower by 2.464.1 t CO2-eq./year, which gives an approximately 13% overestimation of the result by the Gas Emission Site Type method.

Research on CO₂ emission from a raised bog after completion of peat extraction was performed in 2011–2013. CO₂ emissions were determined by the chamber method. Twenty years after the termination of peat extraction, the bog surface was almost entirely devoid of plants. CO₂ emission from the bog varied depending on temperature and water conditions and was 418 mg·m⁻²·h⁻¹ on average during the research period. CO₂ losses on the raised bog were on average 19.7 Mg·ha⁻¹·year⁻¹ during the research period which corresponded to a carbon loss of 5.37 Mg·ha⁻¹·year⁻¹ or mineralisation of 9.6 Mg·ha⁻¹·year⁻¹ of organic mass of 56% carbon content. It is possible to reduce organic mass losses and CO₂ emission to the atmosphere from the bog surface after peat extraction has been terminated by reconstruction of initial water conditions, i.e. retaining a high ground water level and restoration of aquatic plant communities.

Carbon dioxide emission from raised bog surface after peat extraction

Abstract The aim of paper is to present the diversity of water level fluctuations in degraded Baltic raised bogs. An attempt was made to answer the question how strong the diversity of fluctuations is both within each object and between two objects situated close to each other. Moreover, speed and value of the response of water level to atmospheric precipitation were analysed. The spatial scope of the paper covers two Baltic raised bogs in the lower part of the Łeba river valley: Czarne Bagno and Łebskie Bagno. The time scope covers years 2012-2014. The study found that both analysed bogs were a high dynamic in variation of groundwater level. Annual amplitudes of fluctuations in the water table was in the range of 28.4 to 77.9 cm (Łebskie Bagno) and of 45.6 to 105.0 cm (Czarne Bagno). It has been observed that lowering the water level on both peatlands always been recorded in the summer months, whilst the increase in the autumn, which lasted until spring. Retention and the water level on peatlands influenced primarily precipitation. Extreme meteorological conditions that make it less conspicuous is the variation resulting from factors such as location in different parts of the bog or type of degradation.

Diversity of water level fluctuations in degraded Baltic raised bogs. A b s t r a c t. Baltic-type raised bog (dome-shaped) is a type of peatbog with predominant atmospheric water supply and a convex shape, known as the dome. In Poland, 72 Baltic peatbogs have been distinguished, with various degrees of transformation, in the coastal zone and lake districts of the South Baltic Sea. None of them has natural water conditions. Their common name indicates significant similarities due to water supply conditions. However, due to the differences in morphology, both primary and secondary (resulting from the different course and scale of anthropogenic transformations), they may be expected to show some variability within the subtype. The aim of the paper is to present the diversity of water-level fluctuations in degraded Baltic raised bogs. An attempt was made to answer the question how strong the diversity of fluctuations is, both within each object and between two objects situated close to each other. Moreover, speed and value of the response of water level to atmospheric precipitation were analysed. The spatial scope of the paper covers two Baltic raised bogs in the lower part of the Łeba River valley: Czarne Bagno and Łebskie Bagno. To answer the questions asked, the results of measurements of water level and precipitation on the peat bogs were used. The study found that both the bogs show high dynamics in the variation of groundwater level. Lowering of the water level on both peatlands has always been recorded in the summer months, whilst its increase, which lasted until spring, has been observed in autumn. The water retention amount and water level on the peatlands were influenced primarily by precipitation. Extreme meteorological conditions that make it less conspicuous is the variation resulting from factors such as location in different parts of the bog, or type of degradation.

This article describes design and stress analysis of a low-pressure steel vessel that is used for hydrogen storage in metallic alloys based on Ti and Zr. Stress analysis simulations were executed in program called ANSYS Static structural and were used to verify the selected wall thicknesses of the vessel according to standard STN EN 13322-2.
