Terrain-aware cross-attention Swin transformer for digital bathymetric model super-resolution

Geo-spatial Information Science
High-resolution digital bathymetric models (HR DBMs) are crucial for accurate seafloor representation and are widely used in seabed geomorphology, marine mapping, and underwater exploration.

High resolution geomorphological classification of benthic structure on the Western Pacific Seamount

Frontiers in Marine Science, 2022
The benthic structure of seamounts is critical for understanding the ecological environment and for assessing the influence of resource exploitation. However, the characteristics of the benthic structure of the seamount, especially for guyot, are still ...

Increasing Frequency of Coastal Erosion Indicated by a Hindcast Model of Storm‐Driven Forcing Calibrated With Beach Stratigraphy

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Beach stratigraphy at North Beach, Sandy Hook, New Jersey is used to calibrate a model of coastal erosion, establish a model‐based erosion threshold, and evaluate how often threshold conditions have been exceeded since 1979 through hindcast analysis.

Artificial Fish Reef Site Evaluation Based on Multi-Source High-Resolution Acoustic Images

Journal of Marine Science and Engineering
Marine geophysical and geological investigations are crucial for evaluating the construction suitability of artificial fish reefs (AFRs). Key factors such as seabed topography, geomorphology, sub-bottom structure, and sediment type significantly ...

Winter Storm Induced Turbulent Structure Alteration Triggers Sediment Export From an Abandoned Subaqueous Delta

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Winter storms present a major erosional hazard to subaqueous deltas globally, but the associated dynamic mechanisms are still not well understood. Using high‐resolution in situ data collected over a 3‐week period in the abandoned Yellow River subaqueous delta, this study employs three‐dimensional quadrant analysis to examine turbulent ...

On the Influence of Currents and Grain Size on Wave Orbital Motion Scaling Dependence of Sand Ripple Geometry

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Using field observations from the MEGAPEX and Coastal Genesis 2.0 (CG2‐DVT2) campaigns along the Dutch coast, along with laboratory data from the DUNE3 experiment, we examine how ripple geometry responds to variations in orbital diameter, sediment grain size, and current forcing. Results show that ripple wavelength follows a weakly superlinear

New Constraints on Active Normal Faulting in the South Gulf of Evia, Greece: Geometry, Evolution, and Seismic Hazard of the South Coastal Fault System

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In many areas of active faulting, the continuity of normal faults with short or incomplete historical earthquake records and more subdued topographic expressions is not fully understood and consequently the seismic potential of these faults is often underestimated.

Identifying the pre‐Odra river system with hydroacoustic and seismic reflection imagery offshore Rügen Island, southern Baltic Sea

Boreas, Volume 55, Issue 3, Page 790-807, July 2026.
Understanding the course and dynamics of ancient river systems, such as the pre‐Odra, provides valuable insights into the post‐glacial evolution of landscapes and riverine processes. The northwest‐trending pre‐Odra was an important drainage system of the European mainland into the Baltic Basin during and after the Scandinavian Ice Sheet retreat ...

Weichselian history of the Fennoscandian Ice Sheet centre, Kvarken archipelago, western Finland—flow shifts, thermal regime and deglaciation

Boreas, Volume 55, Issue 3, Page 670-701, July 2026.
Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition
