The Relevance of Grain Dissection for Grain Size Reduction in Polar Ice: Insights from Numerical Models and Ice Core Microstructure Analysis [PDF]

, 2017
The flow of ice depends on the properties of the aggregate of individual ice crystals, such as grain size or lattice orientation distributions. Therefore, an understanding of the processes controlling ice micro-dynamics is needed to ultimately develop a ...

Cosmogenic nuclide-derived downcutting rates of canyons within large limestone plateaus of southern Massif Central (France) reveal a different regional speleogenesis of karst networks [PDF]

Earth Surface Dynamics
We present 35 new burial ages (27 sites) based on 26Al / 10Be ratios of terrestrial cosmogenic radionuclides measured in clasts and sediments deep within 12 caves in the southern Massif Central, France.

Geomorphic risk maps for river migration using probabilistic modeling – a framework [PDF]

Earth Surface Dynamics
Lateral migration of meandering rivers poses erosional risks to human settlements, roads, and infrastructure in alluvial floodplains. While there is a large body of scientific literature on the dominant mechanisms driving river migration, it is still not

Time-varying drainage basin development and erosion on volcanic edifices [PDF]

Earth Surface Dynamics
The erosional state of a landscape is often assessed through a series of metrics that quantify the morphology of drainage basins and divides. Such metrics have been well explored in tectonically active environments to evaluate the role of different ...

About the “predecessors” of the 2023 February earthquakes, Turkey

Seismica
In the frame of a comprehensive investigation of historical earthquakes of Anatolia, we propose a re-appraisal of four major earthquakes/sequences occurred after 1000 AD (1114/1115, 1269, 1513/1514 and 1544), which could be considered as predecessors of

Dynamic Evolution of Porosity in Lower-Crustal Faults During the Earthquake Cycle [PDF]

, 2023
Earthquake-induced fracturing of the dry and strong lower crust can transiently increase permeability for fluids to flow and trigger metamorphic and rheological transformations.
