Thermal channelization of suprapermafrost flows

Katarzyna L P Warburton, Joanmarie Del Vecchio, Colin R. Meyer, et al.

Published: 2025-02-19
Subjects: Geomorphology, Hydrology

On many frozen hillslopes, subsurface water above permafrost is routed through regularly spaced, linear features known as water tracks. We test whether water tracks form through thermal channelization, where heat from viscous dissipation in flowpaths deepens the active layer, creating a preferred flow path that attracts more water. We derive equations for suprapermafrost Darcy flow and, using [...]

Where has all the Sinter gone? From the Pink and White Terraces, the Greatest Tourist Attraction of the Southern Hemisphere

Subjects: Environmental Studies, Geology, Geomorphology, Other Geography, Paleontology, Physical and Environmental Geography, Spatial Science, Stratigraphy, Volcanology

Debate continues over the silica sinter Pink and White Terraces, the greatest tourist attraction of the southern hemisphere. The 1886 Tarawera eruption may or may not have destroyed them by burial or eruption. This research compiles surviving sinter. The volume is unexpectedly tiny, which bears on the debate. A database was developed including photography. A forensic approach was taken to [...]

A New Interpretation of Ptolemy's Germania Magna: Employing Computer-Assisted Image Distortion of a Medieval Map by Donnus Nicolaus Germanus to Examine Post-Glacial Geodynamics in Europe

This paper revisits Claudius Ptolemy's depiction of Germania Magna through a multidisciplinary approach, integrating computer-aided distortion analysis of Donnus Nicolaus Germanus's medieval cartography with geological insights. The study proposes that the region underwent significant and complex transformations, likely influenced by tectonic activity, such as the reactivation of the Caledonian [...]

Planform geometric classification of fluvial and tidal channels via machine learning

Kevin Kortum Gardner, Rebecca Dorsey

Published: 2025-01-24
Subjects: Earth Sciences, Geomorphology

Despite forming under different flow conditions, the geometries of tidal and fluvial channel planforms and planform transformations display significant overlap, hindering efforts to differentiate them geometrically. Although studies have demonstrated that gobally, tidal and fluvial planforms are statistically distinct based on meander metrics, there are currently no machine-learning methodologies [...]

An updated version of the SZ-plugin: from space to space-time data-driven modeling in QGIS

Giacomo Titti, Liwei Hu, Pietro Festi, et al.

Published: 2025-01-15
Subjects: Geology, Geomorphology, Software Engineering, Statistical Models

The geospatial community usually makes use of GIS environments to handle databases and pre-process their information. Actual analyses, especially data-driven ones, are performed outside GIS platforms. This interrupts the flow of information and the processing chain in a number of I/O operations that inevitably slow down the overall analytical protocols. The first version of the SZ-plugin [...]

Is the Suez Rift in its post-rift phase?

David Fernández-Blanco, Gino de Gelder, Christopher Aiden-Lee Jackson

Published: 2025-01-04
Subjects: Earth Sciences, Geology, Geomorphology, Physical Sciences and Mathematics, Tectonics and Structure

Failed rifts are widely assumed to enter post-rift quiescence after termination of intracontinental rifting. However, this remains largely untested and a comprehensive evaluation of the rates and patterns of post-rift tectonic (in)activity is lacking. Our novel, rift-scale geomorphic analysis reveals “post-rift” rifting across the archetypal failed rift of Suez, in Egypt. Stacked topographic [...]

Sea level rise submergence simulations suggest substantial deterioration of Indian River Lagoon ecosystem services by 2050, Florida, U.S.A.

The Indian River Lagoon is a 250-km long Estuary of National Significance located along the east central Florida coast of the USA. NOAA tidal records generated at a station located in the central reaches of the estuary indicate sea level rise has accelerated over the past 20 years to an average of 9.6 ± 1.6 mm yr−1 (2003–2022) and it is expected to continue accelerating over the duration of this [...]

Functional regression for space-time prediction of precipitation-induced shallow landslides in South Tyrol, Italy

Mateo Moreno, Luigi Lombardo, Stefan Steger, et al.

Published: 2024-12-11
Subjects: Applied Statistics, Environmental Indicators and Impact Assessment, Environmental Monitoring, Geology, Geomorphology, Hydrology, Multivariate Analysis, Statistical Models

Shallow landslides are geomorphic hazards in mountainous terrains across the globe. Their occurrence can be attributed to the interplay of static and dynamic landslide controls. In previous studies, data-driven approaches have been employed to model shallow landslides on a regional scale, focusing on analyzing the spatial aspects and time-varying conditions separately. Still, the joint assessment [...]

Towards centimeter precision SAR-RFID localization

Arthur Charléty, Morgane Magnier, Mathieu Le Breton, et al.

Published: 2024-11-21
Subjects: Engineering, Geomorphology, Physical Sciences and Mathematics

Radio-Frequency Identification (RFID) shows great potential for earth-sciences applications, notably for landslide surface monitoring at a high spatio-temporal resolution with long-term robustness to meteorological events (rain, fog, snow). The ability to localize RFID tags using Unmanned Aerial Vehicles (UAV) in a Synthetic Aperture Radar (SAR) approach, would offer new possibilites for [...]

DARTS: Multi-year database of AI-detected retrogressive thaw slumps in the circum-arctic permafrost region

Ingmar Nitze, Konrad Heidler, Nina Nesterova, et al.

Published: 2024-10-20
Subjects: Artificial Intelligence and Robotics, Computer Sciences, Earth Sciences, Geomorphology, Physical Sciences and Mathematics

Retrogressive Thaw Slumps (RTS) and Active Layer Detachment Slides (ALD) are widespread thermal mass-wasting hillslope failures triggered by thawing permafrost. Despite increasing rates of these failures, knowledge about their pan-arctic spatial and temporal distribution remains limited. We present the Database of AI-detected Arctic RTS and ALD footprints (DARTS), the largest hillslope [...]

Interseismic deformation fingerprints on the hyperarid coastal landscape in North Chilean subduction

Ehsan Kosari, Sabrina Metzger, Victor Navarro-Sanchez, et al.

Published: 2024-10-10
Subjects: Earth Sciences, Geology, Geomorphology, Geophysics and Seismology, Tectonics and Structure

Along-strike seismotectonic behavior of subduction megathrusts feeds back into the forearc deformation as elastic and permanent deformation. However, whether and how short-term elastic deformation reflects long-term permanent deformation in the forearc and shapes the coastal region remains unclear. To evaluate the forearc deformation, we analyze the interseismic surface deformation obtained from [...]

Landscape evolution of the Black Forest: From the Variscan orogeny to the modern era

Felix Martin Hofmann

Subjects: Geomorphology, Glaciology, Soil Science

With a maximum elevation of 1493 m above sea-level, the Black Forest (Schwarzwald in German) is the second highest mountain range in Germany. It is subdivided in three main natural regions, the northern, central, and southern Black Forest. The Variscan basement of the Black Forest consists of plutonic and metamorphic rocks. Sedimentary rocks formed during the Mesozoic under marine and terrestrial [...]

Published: 2024-09-26
Subjects: Geomorphology

Sand dune morphology is indicative of complex system interactions at a wide range of spatial and temporal scales that govern dune topographic structure. We created an object-oriented topographic framework based on slope attitude, curvature, and contextual analysis to map and characterize sand dune morphology at White Sands National Park, New Mexico, USA that limits empiricism and reliance on a [...]
