title: Glacial geomorphology between the Gran Campo Nevado and Estrecho de Magallanes, Chile (52–53°S, 73°W)

description: We present the first extensive high-resolution glacial geomorphic map west of the Andean Cordillera in southernmost Chile (52.8–53.1°S, 73.0–73.9°W). The map extends over 1565 km<sup>2</sup> and is based on high-resolution satellite images and aerial photographs. At selected locations, the remotely mapped geomorphology was corroborated by field observations. The study area is dominated by glacial erosional landforms (77%) over depositional landforms (23%), with published submarine depositional landforms having been included (e.g. moraines). Glacial drift, kettle kame topography and lateral and frontal moraines form the primary depositional landforms and sediment associations. Glacial cirques, wide U-shaped valleys, whalebacks, roches moutonnées and scoured bedrock characterize most of the mapped area. The spatial distribution of whalebacks and roches moutonnées in the study area indicates a lack of lithological control on their formation and a warm-based, dynamic ice velocity and thickness regime during Patagonian Ice Sheet cover and retreat during the last glacial cycle.

title: Harmonizing multi-source backscatter data using bulk shift approaches to generate regional seabed maps: Bay of Fundy, Canada

description: Advances in sonar technology have revolutionized our ability to map the seafloor, however, differences between legacy and modern data pose challenges when analysing multi-source datasets. Acoustic backscatter recorded via multibeam echosounder is commonly used to characterize the seafloor, but a lack of standardized calibration often yields relative rather than absolute backscatter measurements, hindering comparison between surveys. ‘Bulk shift’ methods have been developed for harmonizing legacy backscatter datasets using overlapping survey areas for relative statistical calibration. This becomes increasingly difficult, though, given many datasets collected over extensive time periods. Backscatter data were collected in the Bay of Fundy, Canada, using multiple sonar systems and vessels over an 18-year period. Here, we propose a reproduceable strategy for harmonizing this large volume of disparate backscatter data using the bulk shift method. A final, harmonized map is presented for the entire Bay of Fundy and is validated using <i>in situ</i> observations from seafloor imagery.

title: Indoor radon measurements in Calabria (Southern Italy)

description: Radon gas from the ground is the main source of indoor concentrations in buildings, regardless of construction characteristics. According to Council Directive 2013/59/EURATOM, EU Member States must establish national reference levels for indoor radon concentrations in workplaces and draw up a National Radon Plan. In Calabria (Southern Italy), maps of indoor measurements at regional scale are not available. A set of 1434 average annual measurements, taken between 2010 and 2021, has been analysed. For a limited sector, a geostatistical approach allowed to map the expected concentrations at ground floor, the spatial uncertainty of estimates, and the probability of exceedance of the 300 Bq m<sup>−3</sup> Italian threshold for workplaces. Highest values characterize the eastern border of the Sila massif. Obtained maps might be used to optimize locations of additional dosimeters, based on geological constraints. Such studies may support urban planning policies and provide recommendations on building techniques.

title: Geomorphology of the Central Kurdistan Region of Iraq: landscapes of the Erbil Plain between the Great Zab and Little Zab Rivers

description: We present the result of the geomorphological mapping of the central sector of the Kurdistan Region of Iraq. Therein, landscape evolution was mostly overseen by the regional geodynamic, related to the Arabia-Eurasia convergence, and in the Quaternary, regional climate fluctuations contributed to shaping landforms. The combination of such processes affected the distribution, types, and evolution of landforms (related to structural, hillslope, fluvial, and karst processes), with a noteworthy influence on the development of the local drainage network, which belongs to Tigris River catchment. The Great Zab and Little Zab Rivers – the main left tributaries of Tigris River – progressively cut anticline ridges growing in the area. Our analyses suggest that the structural deformation of the Zagros also controlled the evolution of the low-order channels of the hydrographic network. Since the Holocene, landforms dynamic was altered by intense human exploitation of the landscape and increased fluctuations between arid and humid conditions.

title: Geology of the Neruda quadrangle (H13), Mercury

description: We present the first geological map of the Neruda Quadrangle (H13), Mercury. H13 is in Mercury’s southern hemisphere between latitudes 22.5°S–65°S, and longitudes 90°E–180° covering a total area of just under 5 million km², equivalent to 6.5% of the planet’s surface. Map digitisation was carried out at scales between 1:300,000 and 1:700,000 for final presentation at 1:3,000,0000, from end-of-mission data products from NASA’s MESSENGER mission. We distinguish three main photogeologic plains units: intercrater, intermediate, and smooth plains. We also distinguish all craters and their materials ≥ 20 km in diameter based on their degradation state. We have completed two versions of the map, one using a three-class crater degradation scheme and one using a five-class crater degradation scheme. In addition, specific geological units were charted for the Rembrandt impact basin. This map has been constructed to provide context and targets for the ESA-JAXA BepiColombo mission to Mercury.

title: Oxia Planum, Mars, classified using the NOAH-H deep-learning terrain classification system

description: We present a map of Oxia Planum, Mars, the landing site for the ExoMars Rover. This shows surface texture and aeolian bedform distribution, classified using a deep learning (DL) system. A hierarchical classification scheme was developed, categorising the surface textures observed at the site. This was then used to train a DL network, the ‘Novelty or Anomaly Hunter – HiRISE’ (NOAH-H). The DL applied the classification scheme across a wider area than could have been mapped manually. The result showed strong agreement with human-mapped areas reserved for validation. The resulting product is presented in two ways, representing the two principle levels of the classification scheme. ‘Descriptive classes’ are purely textural in nature, making them compatible with a machine learning approach. These are then combined into ‘interpretive groups’, broader thematic classes, which provide an interpretation of the landscape. This step allows for a more intuitive analysis of the results by human users.

title: Glacial geomorphology of the Republic of Karelia, northwest Russia: the Younger Dryas-early Holocene ice marginal zone

description: At present, there remains uncertainty surrounding the Younger Dryas-early Holocene glacial history of the Fennoscandian Ice Sheet in northwest Arctic Russia. This stems from a lack of high-resolution ice sheet-scale geomorphological data in the region. To address this, this paper presents 15,355 meltwater and morainic landforms in a new large-scale, glacial geomorphological map of the Younger Dryas-early Holocene ice marginal zone in the Republic of Karelia, northwest Russia. Individual landforms were mapped from relief-shaded renditions of the 2 m resolution ArcticDEM alongside 1 m resolution Esri World Imagery data in a Geographic Information System (GIS). The map, which is presented at a scale of 1: 675,000, will form the basis of a palaeo-glaciological reconstruction of northwest Russia that will inform on ice sheet dynamics – at both a regional- and ice sheet-scale – and provide an important framework through which numerical ice sheet models can be constrained.

title: Vegetation/land cover of a UTM-Hectad in Utande (La Alcarria, Central Spain)

description: In this paper, we present a map of the current state of vegetation and land use in a UTM square measuring 10 × 10 km in Utande (La Alcarria, Central Spain) at a semi-detailed scale of 1:20,000. The map presented here offers an example of how to carry out a series of maps of the plant landscape, using regular grid squares of 100 km<sup>2</sup> (hectads). The map was drawn up using a cartographic method scaled in levels, which can be updated in line with advances in territorial tracking, and enabled us to group together synthetic categories adapted to the biogeographical idiosyncrasy of territory. We recommend combining this phytocoenotic study with another focusing on the flora and the chorology in the same space. A map was obtained with 35 categories, which offers a large-scale image of the biophysical land covers. This will be useful for territorial planning and biodiversity protection.

title: The naïve map of the sixteenth century roads in Spain

description: This paper presents a naïve map that attempts to reflect the vision that Philip II and his advisors probably had of the Spanish road network in the second half of the sixteenth century, a crucial aspect for the choice of the seat of the capital of the kingdom. The elaboration of the naïve map was carried out in two phases: in the first, the road network was reconstructed based on a thorough revision of the primary sources that have survived to the present day. As these sources showed evident problems of completeness, the network was completed using mathematical methods, which were statistically contrasted. The analysis carried out is an important novelty since it shows that most of the transport in the Iberian Peninsula was channeled through the center following a radial structure with six principal axes two centuries before what has been traditionally considered.
