A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Bathymetric effects and corrections in marine CSEM data

Bathymetric effects and corrections in marine CSEM data
The effect of seafloor topographic variations on controlled-source electromagnetic (CSEM) responses is investigated using a finite-difference deling approach for both petroleum and gas-hydrate exploration scenarios. In a deepwater reservoir model, distortions in the inline electric field responses are mainly due to galvanic effects, particularly at ...

Sediment transport and depositional hydrodynamics on the eastern Korean continental margin revealed by surface sediment granulometry

Sedimentology, EarlyView.
ABSTRACT Terrigenous sediments are transported from coastal areas and shelves to deeper continental margins by multiple processes. Understanding these processes is critical for evaluating the ecological impacts of fine‐grained sediment deposition and predicting future changes in sediment dispersal under rapid climate change.

Quantitative analysis of channel characteristics of distributive fluvial systems

Sedimentology, EarlyView.
ABSTRACT Distributive fluvial systems (DFSs) are characterised by a radial distributive channel pattern in planform and dominate modern‐day sedimentary basins. Where aggradation occurs, such as in sedimentary basins, there is increased preservation potential, and therefore, DFSs are hypothesised to constitute a significant portion of the continental ...

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, EarlyView.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In
