Kebijakan Uni Eropa Menghadapi Euroskeptisisme
Authors: Abror Muhammad Yusuf
Published: November 2024

Artikel ini memberikan penjelasan mengenai tantangan Uni Eropa saat ini yaitu euroskeptisisme yang dapat menjadi ancaman eksistensi dari Uni Eropa. Integrasi Eropa yang telah berjalan sejak 1951 di dalam perjanjian Paris harus dapat menyesuaikan keadaan politiknya saat ini. Uni Eropa yang diketahui memiliki kekuatan besar dalam integrasinya ternyata menyimpan rasa skeptisme dari masyarakatnya sendiri. Maka, tulisan ini menjelaskan bertujuan untuk mengelaborasi lebih dalam lagi mengenai euroskeptisisme dan kebijakan dalam mengatasinya. Melalui metode penelitian desk study peneliti mengambil sumber data dari berbagai jurnal, buku, dan kanal resmi lembaga pemerintah. Hasil dari tantangan yang dihadapi Uni Eropa dalam menghadapi euroskeptisisme adalah rasa kurang percaya kepada kebijakan yang dikeluarkan Uni Eropa karena dianggap kurang transparan dan tidak mengakomodir kepentingan negara anggota. Krisis ekonomi menjadi masalah utama bagi eksistensi Uni Eropa yang mengakibatkan apakah organisasi ini masih dapat dipercaya untuk kemajuan anggotanya. Selain itu terjadi ketegangan perbatasan eksternal yaitu gelombang pengungsi dan pencari suaka, sehingga melihat ini sebagai ancaman ketahanan nasional dan ancaman sosial serta ekonomi. Lalu, yang paling penting adalah rasa kehilangan kedaulatan bagi negara-negara anggota karena semua regulasi diatur oleh Uni Eropa.

Published: November 2024

This study is a systematic literature review that objectively analyzes research papers related to domestic programs for delinquent youth. The purpose of this study is to provide basic data necessary for the development of programs suitable for the psychosocial characteristics of delinquent youth by comprehensively analyzing domestic delinquent youth programs. To this end, 79 documents of the delinquent youth program research provided by the Academic Research Information Service (RISS) and Nuri Media (DBpia) were selected and analyzed. The analysis criteria consisted of five items as execution factors: research subject, research method, research design type, program operation, measurement tool and effect, and five items as content factors: program development, program name, program basis, purpose, and treatment intervention factors. As a result of the study, in terms of implementation factors, the research subjects were mainly middle and high school students, and it was found that the rate of verifying the program effectiveness through quantitative research was high. Self-esteem played an important role in the study of delinquent youth programs as a measurement tool. Through this, it was confirmed that it was necessary to expand the program operation method and qualitative research organized into similar age groups. In terms of content elements, there were far more studies reorganizing existing programs, and studies related to the psychosocial functions of delinquent youth were dominated. As for the treatment intervention factor, self-related factors such as self-understanding and self-exploration accounted for the most. Through this, it was confirmed that it is necessary to develop not only programs suitable for the psychosocial characteristics of delinquent youth developed by the researcher, but also various programs related to others. Based on the results of this study, institutions related to delinquent youth should participate in research in the future, and in order to improve the social behavior of delinquent youth, it is necessary to actively develop programs to improve the psychosocial stability and empathy of delinquent youth.

Authors:   Korea Youth Counselling Association, Jo Jeong-Jin , Jo Jeong-A , Lee Mi-Na
Published: November 2024

This study is a case study of sand play counseling that appeared as chaos, death, and rebirth. The subjects of this study are two elementary school children living in Jeollabuk-do. Child A is a third-grade boy at Y Elementary School in City I, and Child B is a fourth-grade girl at B Regional Children's Center in County Y. The results of the study showed that in the chaos stage of Children A and B, they displayed disorderly characters, unrelated tasks, and threatening or confusing play, and showed confusion and conflict about maternal nature. In the death stage, the conflict between uncertainty and certainty began, a strong desire for attachment was shown, and fear and anxiety about reality appeared. In the rebirth stage, a new self appeared, adaptation to daily life was shown, and the play of death and rebirth was in progress, and new thoughts were reborn through death, and they appeared in the order of integration, order, and organization. This shows that sandplay counseling is a process of adaptation that shows inner strength, communication with the world, and harmonious integration to children who have experienced emotional conflict, maladjustment, and confusion during the growing up process.

Authors:   Korea Youth Counselling Association, Hong Young-Keun
Published: November 2024

This study aimed to examine the effects of short-term mindfulness-based group counseling on mindfulness and stress. To achieve this, a short-term mindfulness-based group counseling program was conducted for the general public, and its effects on mindfulness and stress were investigated. Participants were recruited from the Busan area, and a total of 17 individuals participated in the experiment. Among them, 8 were assigned to the experimental group, while 9 were assigned to the control group. The participants in the experimental group underwent short-term mindfulness-based group counseling for five weeks, with one session per week, each lasting two hours. For data collection, a pre-test was conducted before the group counseling for both the experimental and control groups, followed by a post-test after the counseling, and a follow-up test five weeks after the completion of the group counseling. To measure changes in mindfulness, Park Seong-hyun's mindfulness scale was used, and to measure changes in stress, the psychosocial stress scale was employed. The collected data were analyzed using the generalized estimating equations, a non-parametric statistical method. The results showed that while the changes in mindfulness due to the short-term mindfulness-based group counseling were not significant, there was a significant improvement in stress levels. Finally, implications of the findings were presented.

Authors: Alexandre Francisco de Assis Souza , De Alexandria Auzuir Ripardo
Published: November 2024

Existe uma tendência crescente de estudos sobre a temática dos campi inteligentes em todo o mundo. Porém, diferentemente do que ocorre com as cidades inteligentes, que já possuem um conceito formal e global, nenhuma definição universal de campus inteligente foi estabelecida até o momento na literatura. Ademais, nos trabalhos disponíveis, os projetos para caracterização de um campus inteligente, os pilares para o seu desenvolvimento, bem como evidências concretas e mensuráveis de que de fato esses projetos têm impacto positivo no processo de aprendizagem dos alunos, ainda se encontram dispersos e/ou são inexistentes. Nesse sentido, este artigo busca, através de uma revisão sistemática da literatura (RSL), levantar projetos e/ou áreas onde estão concentrados os esforços para o desenvolvimento de campi inteligentes. Para isso a base de conhecimento Web of Science foi escolhida. Os artigos dos últimos três anos foram então classificados, selecionados, analisados e, posteriormente, cada um foi discutido, sendo, por fim, apresentadas suas principais características. Os resultados indicam que a China é o país com o maior percentual de trabalhos publicados sobre campus inteligentes, que a maioria dos artigos avaliados adota as Tecnologias de Informação e Comunicação (TICs) e a Internet das Coisas (IoT) como ponto de partida de projetos envolvendo campus inteligente, que aprendizagem inteligente é o pilar mais citado para o desenvolvimento e gestão de campi inteligentes e que nenhum dos 27 artigos desta revisão apresentou evidências concretas de que os projetos de campi inteligentes demonstraram resultados educacionais mensuráveis para aprendizagem da comunidade acadêmica discente.

Published: November 2024

Abstract. Peter I Island is situated in the Bellingshausen Sea, a region that has experienced considerable climate change in recent decades. Warming sea surface temperatures and reduced sea ice cover have been accompanied by warming surface air temperature, increased snowfall, and accelerated mass loss over the adjacent ice sheet. Here we present data from the first firn core drilled on Peter I Island, spanning the period 2001–2017 CE. The stable water isotope data capture regional changes in surface air temperature and precipitation (snow accumulation) at the site, which are highly correlated with the surrounding Amundsen–Bellingshausen seas and the adjacent Antarctic Peninsula (r > 0.6, p < 0.05). The firn core data, together with the unique in situ data from an automatic weather station, confirm the high skill of the ERA5 reanalysis in capturing daily mean temperature and inter-annual precipitation variability, even over a small sub-Antarctic island. This study demonstrates the suitability of Peter I Island for future deep-ice-core drilling, with the potential to provide a valuable archive to explore ice–ocean–atmosphere interactions over decadal to centennial timescales for this dynamic region.
Impact of atmospheric turbulence on the accuracy of point source emission estimates using satellite imagery
Authors: Gałkowski Michał , Marshall Julia , Fuentes Andrade Blanca , Gerbig Christoph
Published: November 2024

Abstract. Observation-based monitoring of the status of greenhouse gas emissions goals set at the 2015 Paris Climate Summit is critical to provide timely, accurate and precise information on the status of the progress towards these goals. Observations also permit the identification of potential deviations from the adopted policies that could compromise the efforts to reduce the future impact of pollutants on the climate. Current remote sensing capabilities of atmospheric CO2 have demonstrated the ability to estimate emission from its strongest sources, based on imagery of single plumes combined with wind speed estimates. Realistically assessment of the accuracy and precision of the obtained emission estimates is critical, however. Here, we investigate the stochastic impact of daytime atmospheric turbulence on the estimations of CO2 emissions from a lignite coal power plant in Bełchatów, Poland, using a high-resolution (400 m x 400 m x 85 levels) atmospheric model set up in a realistic configuration. We show how the persistent structures in the emitted plumes cause significant uncertainties in retrieved fluxes when applying a commonly-used cross-sectional mass-flux method. on the order of 10 % of the total source strength. These form a significant contribution to the overall uncertainty which remains unavoidable in the presence of atmospheric turbulence. Furthermore, the use of novel temporally-tagged tracers allowed for the decomposition of the plume variability into its constituent parts and explain why spatial scales of variability in plume intensity are far larger than the size of turbulent eddies – a finding that challenges previous assumptions.
Generalized stability landscape of the Atlantic meridional overturning circulation
Authors: Willeit Matteo , Ganopolski Andrey
Published: November 2024

Abstract. The Atlantic meridional overturning circulation (AMOC) plays a crucial role in shaping climate conditions over the North Atlantic region and beyond, and its future stability is a matter of concern. While the AMOC stability when faced with surface freshwater forcing (FWF) has been thoroughly investigated, its equilibrium response to changing CO2 remains largely unexplored, precluding a comprehensive understanding of its stability under global warming. Here we use an Earth system model to explore the stability of the AMOC when faced with combined changes in FWF in the North Atlantic and atmospheric CO2 concentrations between 180 and 560 ppm. We find four different AMOC states associated with qualitatively different convection patterns. Apart from an “Off” AMOC state with no North Atlantic deep-water formation and a “Modern”-like AMOC with deep water forming in the Labrador and Nordic seas as observed at present, we find a “Weak” AMOC state with convection occurring south of 55° N and a “Strong” AMOC state characterized by deep-water formation extending into the Arctic. The Off and Weak states are stable for the entire range of CO2 but only for positive FWF. The Modern state is stable under higher than pre-industrial CO2 for a range of positive FWF and for lower CO2 only for negative FWF. Finally, the Strong state is stable only for CO2 above 280 ppm and FWF < 0.1 Sv. Generally, the strength of the AMOC increases with increasing CO2 and decreases with increasing FWF. Our AMOC stability landscape helps to explain AMOC instability in colder climates, and although it is not directly applicable to the fundamentally transient AMOC response to global warming on a centennial timescale, it can provide useful information about the possible long-term fate of the AMOC. For instance, while under pre-industrial conditions the AMOC is monostable in the model, the Off state also becomes stable for CO2 concentrations above ∼ 400 ppm, suggesting that an AMOC shutdown in a warmer climate might be irreversible.

Published: November 2024

Abstract. Climate-related studies need information about the distribution of stratospheric aerosols, which influence the energy balance of the Earth's atmosphere. In this work, we present a merged dataset of vertically resolved stratospheric aerosol extinction coefficients, which is derived using data from six limb and occultation satellite instruments: SAGE (Stratospheric Aerosol and Gas Experiment) II on ERBS (Earth Radiation Budget Satellite), GOMOS (Global Ozone Monitoring by Occultation of Stars) and SCIAMACHY (Scanning Imaging Spectrometer for Atmospheric Chartography) on Envisat, OSIRIS (Optical Spectrograph and InfraRed Imaging System) on Odin, OMPS (Ozone Monitor Profiling Suite Limb Profiler) on Suomi NPP, and SAGE III on the ISS (International Space Station). The merging of aerosol profiles is performed via the transformation of the aerosol datasets from individual satellite instruments to the same wavelength (750 nm) and their de-biasing and homogenization by adjusting the seasonal cycles. After such homogenization, the data from individual satellite instruments are in good agreement. The merged aerosol extinction coefficient is computed as the median of the adjusted data from the individual instruments. The merged time series of vertically resolved monthly mean aerosol extinction coefficients at 750 nm is provided in 10° latitudinal bins from 90° S to 90° N, in the altitude range from 8.5 to 39.5 km. The time series of the stratospheric aerosol optical depth (SAOD) is created via the integration of aerosol extinction profiles from the tropopause to 39.5 km; it is also provided as monthly mean data in 10° latitudinal bins. The created aerosol climate record covers the period from October 1984 until December 2023, and it is intended to be extended in the future. The merged CREST aerosol dataset (v2) is available at https://doi.org/10.57707/fmib2share.dfe14351fd8548bcaca3c2956b17f665 (Sofieva et al., 2024a). It can be used in various climate-related studies.
Soil organic carbon maps and associated uncertainty at 90 m for peninsular Spain
Authors: Durante Pilar , Requena-Mullor Juan Miguel , Vargas Rodrigo , Guevara Mario , Alcaraz-Segura Domingo , Oyonarte Cecilio
Published: November 2024

Abstract. Human activities have significantly disrupted the global carbon cycle, leading to increased atmospheric CO2 levels and altering ecosystems' carbon absorption capacities, with soils serving as the largest carbon reservoirs in terrestrial ecosystems. The complexity and variability of soil properties, shaped by long-term transformations, make it crucial to study these properties at various spatial and temporal scales to develop effective climate change mitigation strategies. However, integrating disparate soil databases presents challenges due to the lack of standardized protocols, necessitating collaborative efforts to standardize data collection and processing to improve the reliability of Soil Organic Carbon (SOC) estimates. This issue is particularly relevant in peninsular Spain, where variations in sampling protocols and calculation methods have resulted in significant discrepancies in SOC concentration and stock estimates. This study aimed to improve the understanding of SOC storage and distribution in peninsular Spain by focusing on two specific goals: integrating and standardizing existing soil profile databases, and modeling SOC concentrations (SOCc) and stocks (SOCs) at different depths using an ensemble machine-learning approach. The research produced four high-resolution SOC maps for peninsular Spain, detailing SOCc and SOCs at depths of 0–30 cm, 30–100 cm and the effective soil depth, along with associated uncertainties. These maps provide valuable data for national soil carbon management and contribute to compiling Spain's National Greenhouse Gas Emissions Inventory Report. Additionally, the findings support global initiatives like the Global Soil Organic Carbon Map, aligning with international efforts to improve soil carbon assessments. The soil organic carbon concentration (g/kg) maps for the 0–30 cm and 30–100 cm standard depths, along with the soil organic carbon stock (tC/ha) maps for the 0–30 cm standard depth and the effective soil depth, including their associated uncertainties, —all at a 90-meter pixel resolution— (SOCM90) are freely available at https://doi.org/10.6073/pasta/48edac6904eb1aff4c1223d970c050b4 (Durante et al., 2024).
An optimal transformation method for inferring ocean tracer sources and sinks
Authors: Zika Jan D. , Sohail Taimoor
Published: November 2024

Abstract. The geography of changes in the fluxes of heat, carbon, freshwater and other tracers at the sea surface is highly uncertain and is critical to our understanding of climate change and its impacts. We present a state estimation framework wherein prior estimates of boundary fluxes can be adjusted to make them consistent with the evolving ocean state. In this framework, we define a discrete set of ocean water masses distinguished by their geographical, thermodynamic and chemical properties for specific time periods. Ocean circulation then moves these water masses in geographic space. In phase space, geographically adjacent water masses are able to mix together, representing a convergence, and air–sea property fluxes move the water masses over time. We define an optimisation problem whose solution is constrained by the physically permissible bounds of changes in ocean circulation, air–sea fluxes and mixing. As a proof-of-concept implementation, we use data from a historical numerical climate model simulation with a closed heat and salinity budget. An inverse model solution is found for the evolution of temperature and salinity that is consistent with “true” air–sea heat and freshwater fluxes which are introduced as model priors. When biases are introduced into the prior fluxes, the inverse model finds a solution closer to the true fluxes. This framework, which we call the optimal transformation method, represents a modular, relatively computationally cost-effective, open-source and transparent state estimation tool that complements existing approaches.
Geospatial Capacity Building for Flood Resilience in the Sahel: the SLAPIS project case study

Published: November 2024

Abstract. This study focuses on the development of a people-centred early warning system (EWS) against floods in the Sirba River basin between Niger and Burkina Faso. This densely populated area has witnessed an increase in extreme flooding events in recent years. Several flood forecasting systems in the Sahel exist, although there is no EWS that integrates the four components of people-centred EWSs, namely risk knowledge, monitoring and warning service, dissemination and communication, and response capacity. The proposed EWS, named SLAPIS, includes a risk knowledge component that involves defining four levels of vigilance. Its monitoring and alert component involves a user-friendly web application containing real-time data collected through automatic stations. The EWS communicate seamlessly with the national alert system. The response capacity is strengthened through the creation of a flood zone atlas. In this framework, the EWS integrates significant geoinformatics in preparation of local risk reduction plans and the awareness of local communities. In the SLAPIS case study, multi-temporal classifications were conducted using Sentinel-2 data and high-resolution images (approximately 10 cm) generated through Structure from Motion (SfM) techniques. Digital Terrain Model (DTM) creation for hydraulic model calibration employed a multiscale approach, incorporating GNSS survey data processed via Precise Point Positioning (PPP), HydroSHEDS (approximately 100m resolution), and commercial 10m resolution data. All information was calibrated, harmonised, and integrated into the EWS model, which is accessible via a web platform. Capacity building encompassed direct training and field implementation to streamline the primary EWS generation steps.

Published: November 2024

Abstract. The north eastern region of India is characterized by limited physical connectivity and challenging terrain, that requires innovative approaches for effective developmental planning and monitoring using geospatial data and user-centric applications. This paper focuses on leveraging space-based data and applications to address these challenges and enhance decision-making processes in governance. A unified framework for interoperable spatial data sharing has been developed, ensuring that data is easily discoverable, searchable, and consumable through metadata standards and OGC interoperable data services. A dedicated spatial data repository has been established, offering real-time access to over 1400 geospatial datasets and facilitating better decision-making and geo-analytics among diverse user groups. The repository operates on an open-source platform with integrated map viewers and geo-analytics tools, allowing for interactive exploration and visualization of geospatial data. Additionally, 35 user-centric geospatial applications have been operationalized, all developed using open-source geospatial tools and standards. Capacity building programs have been conducted to increase awareness and maximize the utilization of geospatial data services and applications across the region. The platform has boosted utilization of geospatial data services and applications in the region for overall planning and developmental activities for smart governance and societal benefits.

Published: November 2024

Abstract. The issue of flooding in the town of Jasaan in Misamis Oriental province poses a threat to 42% of the population. This is more worrisome during the rainy season, especially in the months of October and December were typhoons are at their strongest and passes in proximity to Mindanao island. Residents have reported significant damage to their properties due to flooding, and typhoons like Super Typhoon Odette in December 2021 have worsened the situation when it brought rain while the dike system was dilapedated. The dike systems in the area have been damaged by these natural disasters, and the lack of repair has made the situation worse. Flood hazard mitigation measures have since been implemented. With the frequent occurrence of flooding in the Cabulig River, a validated model is needed to investigate the behavior of the river during strong and significant rainfall events while taking into consideration the current state of the existing dike systems by coupling the modelling systems HEC-HMS and HEC-RAS. Data from the USGS, DOST-PAGASA, DPWH, and Landsat 8 have been used in this study. The results of the Flood Inundation Analysis showed that most of the flooded areas in Barangay Lower Jasaan and Bobontugan are urban areas which exacerbates during heavy rain events. The results of the simulations of the researchers' proposed dike structures shows that it should be extended towards the upstream direction and a minimum dike height of 2.5m is needed with no discontinuities. A 2.5m high dike on the Bobontugan side should also be placed.

Abstract. Hail is one of the costliest natural hazards in Switzerland and causes extensive damage to agriculture, cars, and infrastructure each year. In a warming climate, hail frequency and its patterns of occurrence are expected to change, which is why understanding the long-term variability and its drivers is essential. This study presents new multidecadal daily hail time series for northern and southern Switzerland from 1959 to 2022. Daily radar hail proxies and environmental predictor variables from ERA5 reanalysis are used to build an ensemble statistical model for predicting past hail occurrence. Hail days are identified from operational radar-derived probability of hail (POH) data for two study domains, the north and south of the Swiss Alps. We use data from 2002 to 2022 during the convective season from April to September. A day is defined as a hail day when POH surpasses 80 % for a minimum footprint area of the two domains. Separate logistic regression and logistic generalized additive models (GAMs) are built for each domain and combined in an ensemble prediction to reconstruct the final time series. Overall, the models are able to describe the observed time series well. Historical hail reports are used for comparing years with the most and least hail days. For the northern and southern domains, the time series both show a significant positive trend in yearly aggregated hail days from 1959 to 2022. The trend is still positive and significant when considering only the period of 1979–2022. In all models, the trends are driven by moisture and instability predictors. The last 2 decades show a considerable increase in hail days, which is the strongest in May and June. The seasonal cycle has not shifted systematically across decades. This time series allows us to study the local and remote drivers of the interannual variability and seasonality of Swiss hail occurrence.
Quantitative Risk Assessment for Airborne Transmission of Disease
Authors:   , Mikszewski Alexander
Published: November 2024

This project made important contributions to the science of modeling airborne transmission of respiratory tract infection, including methods and applications useful to public health and building design. The novelty of the work included combining airborne transmission risk during close contact with the infection risk from breathing shared indoor air at the room scale. Original estimates of the infectious airborne emission rate were developed for nine different pathogens for different respiratory activities, such that airborne contagiousness can be compared. Further research is needed to incorporate the developed methods into broader epidemiological models for cost-benefit analysis of ventilation improvements at scale.

Published: November 2024

This thesis addresses the challenges pertaining to the design and development of textile yarn-based lithium-ion batteries, which are vital for powering personal wearable electronics. Overall, the thesis involved the selection, synthesis, modification, and testing of several battery materials and their fabrication into high performance yarn-based electrodes. The inorganic nickel-rich materials were used to form yarn-based cathodes. This was followed by the modification of silicon materials by sandwiching them between molybdenum disulphide 2D nanosheets, which were then used to form anode yarns. Finally, the anode and cathode yarns were combined into a fully functional yarn battery capable of powering wearable electronics.
Examining the Impact of Economic Policy Shocks on Investment: Evidence from Pakistan and its Trade Partners

Published: November 2024

The objective of this study is to investigate the effect of both internal and external policy ambiguity on aggregate investment in Pakistan and its bilateral trade partners from the fourth quarter of 2010 to the fourth quarter of 2021. To achieve this, study uses economic policy uncertainty index for each country as a proxy for internal policy volatility. External policy volatility is measured by constructing a compound index that accounts for the trade weight of each country's policy uncertainty index. Further to find out the relationship, Panel PMG-ARDL model used and findings indicate that investment decrease with increase in uncertainty. Additionally, the research delves into the nonlinear relationship between investment and uncertainty and results demonstrate a U-shaped relationship between uncertainty and investments. Furthermore, Specific values were calculated to determine whether the effects of policy shocks are positive or negative, showing that internal policy shocks are more harmful than external ones. The study also provides policy implications based on these findings. Since internal policy insecurity has a stronger negative impact on investment than external factors, it is essential for policymakers in Pakistan to prioritize reducing ambiguity in internal policies. Implementing clear, consistent, and stable economic policies can help alleviate the negative effects of uncertainty on investment.
Rocks and buildings in the Sofia City center - a geological and historical city tour
Authors: Pristavova Stefka , Marinova Kamelia
Published: November 2024

The most used rock materials that served to build the modern appearance of Sofia’s central streets and buildings are presented. Different local genetic types of rocks were utilized for the construction of modern Sofia: igneous rocks (monzonites, gabbros, rhyolites); sedimentary rocks (varieties of limestone and sandstones); and metamorphics (mainly marbles). A small part of rock materials was imported, mainly for the interior design of the buildings, for instance in Sofia University “St. Kliment Ohridski”, St. Alexander Nevsky Cathedral, and others. The most used rock material for buildings and streets were the monzonites from the Vitosha Mountain, and this is the reason why Sofia City is noted as “the monzonite capital” of Bulgaria. The emblematic buildings, streets and squares in the city centre, with their rock building material, characteristics, and historical significance are briefly described.

The Late Paleozoic and Mesozoic sequences in the Svoge, West Balkan and Fore-Balkan units (Western Bulgaria) are exposed in eight points. Most of the points are within the area of the Iskar Gorge. At point 1, SE of the village of Redina on the road to Svoge, the rocks of the Late Carboniferous Svoge Formation can be observed – terrigenous sediments of alluvial-limnic character with preserved megaflora. Triassic and Jurassic sequences are traced in the area of point 2 near the village of Zasele. Point 3 is in Triassic sediments and provides a view from the east of the Upper Carboniferous diorites of the Petrohan intrusion. Karst processes are developed in some sections of the Iskar Gorge and caves of different sizes can be seen. One of them is the Temnata Dupka Cave (point 4), which is formed in the Middle Triassic rocks of the Iskar Carbonate Group. In the area of the village of Cherepish (point 5), the lower part of the Lower Cretaceous Vratsa Urgonian Group (Cherepish Formation) is exposed. The upper level of the Vratsa Urgonian Group can be traced in the next point 6, where the geological phenomenon Ritlite (Lyutibrod Formation) is situated. In the area of the village of Chelopek (point 7), a continuous section between the Cretaceous and Paleogene is observed. Southwest of Vratsa, at point 8, the Ledenika Cave is revealed, located in the Upper Jurassic–Lower Cretaceous carbonate sediments of the Gintsi Formation.
Middle and Upper Devonian depositional settings of the Moesian Terrane (northern Bulgaria)
Authors: Andreeva Polina
Published: November 2024

The Devonian sediments from the Moesian Terrane (Moesian Platform, northern Bulgaria) are known only from oil and gas prospecting wells. Middle and Upper Devonian deposits are interpreted as formed in great variety of depositional settings. Thus, the Eifelian carbonates were regarded as inner- and mid ramp deposits developed in a shallowing-upward sequence. The shallowing tendency continued during the Givetian and Frasnian, when arid tidal-flat and lagoon settings predominated. At the beginning of the Famennian, a climate change occurred when the Moesian Terrane was removed from the Subtropical Arid to the Warm Temperate Climatic Zone. Then, carbonate deposition took place in various shallow- to deepermarine environments.

Published: November 2024

The Sherubay-Nura section is located in the Karaganda Coal Basin, paleogeographically accretionary complexes of Kazakhstania, a Middle Paleozoic terrane that was colliding with Siberia during the Late Devonian. Rich ammonoid faunas have been discovered in this and other outcrops of the region during Sovietera geological mapping. We present the first field reassessment of the section since the 1980s, elucidating previously unknown deep-water character, gamma-spectrometry response, position of ammonoid limestones in the facies succession, and thermal overprint due to basalt dike intrusions and hydrothermal flushing.
Evolution of the Paleozoic (Silurian-Devonian?) Sredogriv metamorphics, NW Bulgaria
Authors: Kiselinov Hristo
Published: November 2024

The Sredogriv metamorphics are located in NW Bulgaria and referred to the Balkan Terrane. They represent an alternation of different parametamorphites and, to a lesser extent, polymict metaclastic rocks, phyllites and calcareous schists. Various in size allochthonous bodies from metamorphosed magmatites have been tectonically included among them. Recent studies on the Sredogriv metamorphics indicate their formation in a marginal basin of probable Silurian–Devonian age affected by subsequent Carboniferous tectonic processes and greenschist metamorphism.
