title: The paleolandscape evolution of the southwestern coast of Sardinia (Italy) and its impact on Mesolithic settlements

description: We present a geomorphological map of the southwestern coast of Sardinia encompassing inland and offshore areas of the S’Omu e S’Orku Mesolithic site. The submerged area was documented by high-resolution multibeam bathymetry combined with Side-Scan Sonar data. The emerged coastal area was surveyed using Uncrewed Aerial Vehicle Remote Sensing and field surveys. The inland landforms were shaped by coastal, fluvial, and gravity-induced processes. Most of the submerged landforms appear be modeled in subaerial conditions during sea-level lowstands, and then sealed by the rising sea level. The coastal evolution has been characterized by the rapid cliff retreat facilitated intense linear erosion of watercourses, by debris flows, rockfalls and toppling. Geomorphological evidences of cliff retreat due to landslide was supported by a simplified analytic hydraulic model of the wave-cliff interaction. These processes and the sea level rise canceled any possible Mesolithic settlement along the coast. The survival of the S’Omu e S’Orku site is only due to a protected morphological position and to the distance from the Early Holocene coastline. The dearth of coastal Early Holocene prehistoric sites is likely the outcome of the presented coastal dynamics.

title: Influence of COVID-19 on night-time lights in Czechia

description: Night-Time Light (NTL) satellite imagery is widely recognized and valued as a powerful tool for spatial analysis and research. Despite its global popularity, there is absence of similar studies dealing with NTL intensity in Czechia. Using VIIRS/DNB data, our study focused on analyzing the changes in night-time light intensity before and during the coronavirus restrictions. These restrictions had a substantial impact on social and economic life, particularly during the peak of pandemic, affecting not only Czechia but also other regions worldwide. A mosaic of the study area was prepared, followed by the aggregation of the original raster data to municipalities with extended power (MEPs) and calculation of the average light index (ALI). The resulting typology made it possible to identify regional differences in NTL intensity. The main hypothesis was confirmed, it was observed that the ALIexhibited a decrease of 18% in 2020, whereas in 2021, the decline averaged at 9%.

title: Glacial geomorphology of the northwest Laurentide Ice Sheet on the northern Interior Plains and western Canadian Shield, Canada

description: The majority of the Northwest Territories of mainland Canada was covered by the Laurentide Ice Sheet during the Last Glacial Maximum. The increasing coverage of high resolution remotely sensed data provides new opportunities to map the glacial geomorphology and study the glacial history of this remote location. Here we present a comprehensive map of glacial landforms within the northern Interior Plains and adjacent areas of the Canadian Shield, comprising around 6% of the Laurentide Ice Sheet bed. Twelve landform types were mapped from the high resolution ArcticDEM: ice flow parallel lineations, subglacial ribs, crevasse-squeeze ridges, major and minor moraine crests, hummocky terrain complexes and ridges, shear margin moraines, major, minor and lateral and submarginal meltwater channels, esker ridges and complexes, glaciofluvial complexes, perched deltas, raised shorelines and aeolian dunes. Together, these landforms provide a record of the highly dynamic behaviour of the northwest sector of the Laurentide Ice Sheet.

title: Sediments and bedforms of the Harle tidal inlet (Wadden Sea, Germany)

description: The paper presents a map of sediment surface distribution and bedforms in the Harle tidal inlet, German Wadden Sea. Data collection, processing, and map editing were realized within the sublittoral mapping program of Lower Saxony national waters carried out by the NLWKN – Coastal Research Station. The map is the result of the combined use of multibeam echosounder, sub-bottom profiler, and ground-truth data. The sediment characterization is achieved by an unsupervised approach using an Object-Based Image Analysis (OBIA) on a normalized backscatter mosaic, verified by nineteen sediment samples. Morphometrical parameters and sub-bottom data provided important information to identify hard substrates and bedforms.

title: Hydrogeology of a complex karst catchment in Southern Dalmatia (Croatia) and Western Herzegovina (Bosnia and Herzegovina)

description: Our study focuses on a sizeable transboundary karst catchment in Croatia and Bosnia and Herzegovina, extending over 2000 km<sup>2</sup>. A complex underground conduit system and extreme karst forms heterogeneity are the main characteristics of the area in question. Since determining the boundary of such a large and complex catchment is difficult, we used different kinds of data sets, of which the most relevant are the available geological data, hydrochemical data, hydrological data, and tracing tests data, to divide the regional catchment into six subcatchments. We also examined past archived reports and carried out new hydrological investigations of several major and minor springs. Our research results in a hydrogeological map that can be used as a base for establishing site-specific groundwater protection zones, for water balance calculations and the planning of new research in this area, especially the ones regulating combined cross-border efforts to prevent groundwater contamination and ensure sufficient drinking water.

title: Structural geology of the eastern termination of the Mt. Kumeta-Alcantara line (NE sicily, Italy)

description: In this paper we show data from new detailed geological-structural field surveys, integrated with preliminary photogrammetric analysis, presented in a 1:10,000 scale geological map. The field-based investigations covered an area of about 60-km<sup>2</sup>, located at the southern termination of the Calabrian Forearc, in NE Sicily (Italy), at the intersection of two key regional-scale fault systems. These are represented by the Peloritani Sole-Thrust, along which the Kabilo-Calabride orogenic edifice overthrusted onto the Apenninic-Maghrebian Chain, and the Mt. Kumeta-Alcantara Line, which played a key role in the post-Oligocene evolution of the Nubia–Eurasia converging margin. The collected data permitted the recognition of a new terrigenous stratigraphic unit, the Malvagna Flysch, and the acquisition of updated structural information useful to better understand the kinematics of the easternmost portion of the Mt. Kumeta-Alcantara Line. The geological map provides new insights for the reconstruction of the geodynamic evolution of this sector of the Calabrian Forearc.

title: Onshore hydrocarbon seep detection using the GF-5 hyperspectral image: a case study in the Karamay area, NW China

description: Satellite remote sensing has been widely utilized for petroleum detection offshore since oil spill is normally widespread. However, the onshore hydrocarbon detection is insufficient because the lower spectral resolution of previous satellites made it difficult to identify small scales of seepages. In this study, a dataset of the High-Resolution 5 satellite (GF-5) of China was chosen to directly detect hydrocarbon seeps in the Karamay area. First, an IDL program was used to remove the vertical tripe noise of the image to ensure the high quality of the image. Second, use principal component analysis (PCA) was combined with the classification and regression trees (CART) method RuleGen to process the image. The detected hydrocarbon information was enhanced by RGB color synthesis. The results show that the methods can detect hydrocarbon effectively. Field verification results show that the accuracy is 86.5%. This study provides an effective method for hydrocarbon detection using GF-5 data.

title: The glacial geomorphology of the Mackenzie Mountains region, Canada

description: During the Last Glacial Maximum, the Mackenzie Mountains region was glaciated by three distinct ice sources; the Laurentide Ice Sheet, the Cordilleran Ice Sheet, and independent montane glaciers. Rapid ice sheet thinning of the Laurentide-Cordilleran ice saddle in the south of this region contributed to rapid sea level rise events and influenced the style of deglaciation to the north. The current understanding of the glacial history of the broader region has been established through mapping from aerial imagery and early surveys between the early 1970s to the 2010s. The central portions of the Mackenzie Mountains have not yet been mapped. We present a new glacial geomorphological map for the Mackenzie Mountains region covering over 220,000 km<sup>2</sup>. This updated geomorphological map will form the basis of future work to reconstruct the former maximum ice extents, flow dynamics, and retreat pattern.

title: Landslide susceptibility assessment on a large scale in the Podsljeme area, City of Zagreb (Croatia)

description: The study presents a landslide susceptibility assessment on a large scale in the City of Zagreb (Croatia). The susceptibility analysis was performed using the Weight of Evidence model in the pilot area (21 km<sup>2</sup>) and applying the obtained weight values for each class of conditioning factors in the study area (130 km<sup>2</sup>). The input data were LiDAR-based landslide inventory and six conditioning factors derived from 5 m LiDAR DTM, 5 m SfM DEM, and geological and land-use maps. The validation of the susceptibility assessment for the study area was evaluated with a ROC curve, which showed a high prediction rate (AUC = 84.4%), similar to the prediction rate for the pilot area (AUC = 86.9%). Based on the results, it can be concluded that the proposed method for large-scale landslide susceptibility assessment, where susceptibility conditions are defined in smaller pilot areas, can be applied to larger research areas with similar geomorphological and geological conditions.

title: Abandoned underground mines in Nízký Jeseník Upland (Czechia)

description: This paper summarises the results of an inventory of abandoned underground mines within the Nízký Jeseník Upland (Czechia, Central Europe). The area has a long and complex history of mining. During the period between the 11th and 13th centuries, the upland was the centre of ore mining, and later, during the 18th and 19th centuries, it transitioned into slate mining for roofing. From 2016 through 2018, we collected detailed data from 137 mines to better understand their parameters and functioning within the contemporary landscape. The data were mainly focused on the geomorphic character of underground mines, as the existing inventories focus on various other aspects. The results were processed into an interactive web map using ArcGIS Online's online mapping software. Relations between parameters were assessed using three methods: the χ2 test for a contingency table, ANOVA and linear regression.

title: Landscape evolution and the karst development in the Ojo Guareña multilevel cave system (Merindad de Sotoscueva, Burgos, Spain)

description: The Ojo Guareña karst system (OG) is located in the SE Cantabrian Range in northern Spain (Burgos, Spain). It is a multilevel cave system composed of 6 levels and is one of the longest cavities in the Iberian Peninsula (110 km). The spatial patterns and geomorphological characteristics of OG constitute a first-order record for studying the principal mechanisms of how the karst evolved by reconstruction and analysis of the external landscape. This extended karst system is attributed to the action of the local drainage system driven by Quaternary climatic fluctuations and lithological-structural controls. To contribute to this debate, we performed a detailed geomorphological mapping of this area (1:25,000 scale), differentiating the landforms according to the main geomorphological processes (structural, gravity, fluvial, glacial, weathering and polygenetic) involved. These datasets were used to draw a detailed geomorphological map and give a preliminary interpretation of the local landscape evolution.
