A new period of investigations and compilation of geological maps starts about 1840 and is closely related with the development of stratigraphic knowledge; therefore, this period marks the beginning of mapping using the stratigraphic concept (Helmersen 1841). The Geological Committee in St. Petersburg, founded in 1882, at the very beginning of its activities started the compilation of a geological map including the present territory of Lithuania. The works of Antony Karol Giedroyc (Antanas Karolis Giedraitis) were published in 1895 (Giedroyc 1895), and the volume included a map which displays the occurrences of Quaternary and Pre-Quaternary (Tertiary, Cretaceous, and Jurassic) sediments and rocks. The map is constructed on the basis of direct observations and descriptions of outcrops and exposures of Quaternary sediments and Pre-Quaternary rocks carried out by the author, also based on evidence by local people. The main occurrences (provinces) of Pre-Quaternary rocks mapped by Giedroyc are confirmed by the modern geological mapping of the 20th century; therefore, the map of Giedroyc (1895) is regarded as a pioneering work of modern geological mapping using international stratigraphic standards.","PeriodicalId":55401,"journal":{"name":"Baltica","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70648938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The complex geometry and difficult-to-access areas of the cave have made the use of traditional mapping methods challenging. To overcome these limitations, this study utilized TLS and UAV technology to produce highly accurate 2D and 3D data for cave management and risk assessment purposes. The TLS system was used to create a detailed 3D point cloud of the cave interior, while the UAV system generated a 3D model of the surface topography outside the cave. The two sets of data were combined in the GIS environment using a geodetic network established in the study area, providing a common geodetic reference system for both TLS and UAV data. The study found that the cave area is 13,750 m2, which is smaller than the area of 18,000 m2 that was previously estimated using conventional measurement methods. The volume and ceiling heights of the cave were calculated using the elevation models generated from TLS point cloud data. The 3D point cloud data were also used to map dripstone locations on the floor and ceiling of the cave, and the boundaries of rock blocks on the ground were precisely determined. The study identified potential risks associated with the cave, particularly the risk of rockfall in the source rock areas around the cave entrance and the southern part of the cave. The nearest building to the cave is approximately 35 meters away, and all the buildings in the area are less than 300 meters from the cave. In the event of the cave collapse, the buildings in the southern part of the cave are at risk of rockfall. This study demonstrates the effectiveness of combining data from TLS and UAV systems to generate broad and sensitive cave mapping and risk assessment data, which are critical for cave management and safety. The collected data can be used for cave stability investigations and rockfall risk assessments. This study provides a foundation for future explorations of the Akcakale cave and highlights the potential for modern surveying techniques to enhance our understanding of complex geological structures such as caves.","PeriodicalId":55401,"journal":{"name":"Baltica","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70648952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Localization of ice jams and ice drift zones could mean a faster and better response to possible flooding areas, and classification of river ice could help better predict freezing and thawing conditions that hinder the use of commercial and recreational river transport. As many freezing-prone rivers are located in regions with short winter days and common cloud cover, the use of optical sensors can be very limited, therefore, the use of Synthetic Aperture Radar (SAR) – a microwave imaging radar – is more applicable. In this article, Sentinel-1 SAR C-band imagery is used to create derivate texture rasters, which are analyzed, compared with known optical imagery and then considered for river ice detection and discrimination. These results are compared in terms of their effectiveness for river ice discrimination, and the most useful methods are selected. The chosen methods are then compared in an experimental machine-learning model capable of detecting and classifying ice and water. Various machine-learning approaches (both classical and deep-learning) are considered and compared, and the best models are selected. The purpose of this research is to analyze the capability of texture rasters, calculated from a gray-level co-occurrence matrix (GLCM), to discriminate river ice. Texture rasters have recently been applied for river ice classification by de Roda Husman et al. (de Roda Husman et al. 2021), but included only three metrics. This research aims to expand on this knowledge by comparing eight metrics instead of three, as well as including an experiment with a deep-learning model. The results demonstrate that in machine-learning experiments, only one texture measure out of eight (GLCM Mean calculation) is able to discriminate river ice better than discrimination from a standard SAR backscatter intensity image (the baseline).","PeriodicalId":55401,"journal":{"name":"Baltica","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70649380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The b-value was calculated as 0.82 ± 0.02 by considering the magnitude of the completeness value as Mcomp = 1.9, and it is relatively small compared to typical b ≈ 1 for the magnitude-frequency relationship of aftershocks. This low b-value may also be caused by the abundance of aftershocks with ML ≥ 4.0. The p-value was computed as 0.80 ± 0.02 with c-value = 0.279 ± 0.098 and is smaller than the global value of p ≈ 1. This low p-value may be due to a relatively slow decay rate of aftershock activity, and the modified Omori model seems appropriate for the estimation of decay parameters. The Dc-value was estimated as 1.87 ± 0.07. This large value shows that aftershocks are homogeneously distributed and more clustered at larger scales/in smaller areas. The temporal variation of b-value indicates that decreases in b-value may result from the gradual increase in the effective stress following the larger aftershocks. The lowest b-values and Mamax values greater than 5.0 were observed in the north, south and southwest parts of the mainshock including Pütürge and Erkenek segments. These results show that there is an apparent relation between the smallest b-values and the largest Mamax values. The largest p-values were estimated in and around the main shock including Pütürge segment. The regions with the smallest b-value and the largest p-value have high stress and coseismic deformation, respectively. Stress variations and coseismic deformation are extremely effective on the changes of b- and p-values. As a remarkable result, aftershock hazard following the mainshock may be considered extremely related to aftershock parameters, and detailed analyses of the region-time-magnitude characteristics of aftershocks are recommended for a preliminary evaluation following the mainshock.","PeriodicalId":55401,"journal":{"name":"Baltica","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70649066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Holocene strandplain along the east-facing (leeward) shoreline has experienced rapid retreat due to the anthropogenically induced sediment deficit. The study site is located just updrift of the erosional-depositional fulcrum segment, with southerly longshore transport resulting in the accumulation of eroded sand along a drift-aligned spit. The most prominent erosional indicators are mature pine trees in different stages of undercutting, toppling, fragmentation, and burial. Morphological features include scarps in paleo-beach/dune ridges (height: > 1 m), as well as modern berm scarps. Mineralogical indicators are exemplified by heavy-mineral concentrations (HMCs) of variable thickness (some > 2 cm) and concentration. Representative samples show a substantial increase in bulk low-field magnetic susceptibility ranging from < 10 µSI common to the nearby Holocene coastal lithosomes to > 8,000 µSI in second-cycle HMCs within berm enrichment zones. A conceptual morphosedimentary model describing the recent and current state of the system, as well as the preservation potential of specific structures and recognition in geological research (e.g., georadar signatures of buried trees and HMCs) is proposed.

An important part of this plan is related to geological investigations for the site selection, design and construction of deep geological repository (DGR) for spent nuclear fuel and high-level long-lived radioactive wastes. The main task of geological investigations is to select a suitable geological environment for DGR, which is closely related to that of the DGR site. There are several alternative geological formations potentially suitable for DGR in Lithuania. Selection of the most suitable DGR site should be made and the DGR concept should be developed applying clear methodology. The proposed methodology is based on the safety requirements established by International Atomic Energy Agency (IAEA), systematic approach and criteria that are widely used worldwide. The suitability evaluation criteria are divided into 4 groups according to the factors responsible for the stability and safety of the DGR system. The highest rank of significance is assigned to the group of criteria that are associated with the factors responsible for the loss of the long-term stability of the system. The criteria associated with the DGR system confinement are assigned to the second group and are ranked second in significance. The third group of evaluation criteria could be characterized as a data availability group. It consists of the evaluation criteria associated with the emergence of uncertainties. Features or processes responsible for the improvement of formation properties over time are assigned to the fourth group and have the lowest rank of significance.

These methods involve using and analysing various spatial topographic and thematic databases, including the databases of ortho-photo images, bogs and peatlands, CORINE land cover, crop fields, forest cadastre, flood-prone areas, the geomorphologic database, the database of relief cadastre as well as that of reclamation status and wet soils. In this study, the intensity of geodynamic processes was estimated using mathematical models, which include a number of factors behind surface transformation (accumulation/degradation) processes, i.e., the origin of the terrain, its morphographic and morphometric indicators, lithology, soil cover, the degree of sediment and soil wetness, and natural vegetation cover. In addition, the impact of the factors inhibiting surface erosion (ratio of clay and sand particles in the surface layer, slope inclination, humus content in soil, binary nature of soil-forming sediments) was evaluated. The cartographic analysis results were compared with the data obtained from the terrain investigation in key areas. The surface analysis based on the spatial distribution of geomorphological relief types, their roughness, land cover, forest, soil types, reclamation and soaked lands shows that weak deflation (up to 1 mm / year, 1214.8 km²), weak erosion (up to 1 mm / year, 367.1 km²) and medium biogenic accumulation (1–2 mm / year, 223.5 km²) are taking place in the Coastal Lowland.","PeriodicalId":55401,"journal":{"name":"Baltica","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70649113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
