Side-Scan Sonar Applications for Evaluating Coastal Structures [PDF]
, 1988 Applications of side-scan sonar for inspecting coastal structures were evaluated. Results were based on 6 years of structure inspections, including structures on the Atlantic, Pacific, Gulf, and Great Lakes coasts of the United States. Most of the structures inspected were jetties and breakwaters; however, applications for vertical wall structures and ...

Deep Learning Methods for Assessing Time‐Variant Nonlinear Signatures in Clutter Echoes
Advanced Intelligent Systems, Volume 8, Issue 4, April 2026.Motion classification from biosonar echoes in clutter presents a fundamental challenge: extracting structured information from stochastic interference. Deep learning successfully discriminates object speed and direction from bat‐inspired signals, achieving 97% accuracy with frequency‐modulated calls but only 48% with constant‐frequency tones. This work

Tectonics, Volume 45, Issue 4, April 2026.Abstract The Northern Aegean region preserves a complex deformation pattern shaped by Miocene extension driven by retreat of the Hellenic subduction system, later overprinted by Plio–Pleistocene transtension linked to the westward propagation of the North Anatolian Fault (NAF). Although numerous structural, geophysical and geochronological studies have

Sedimentology, Volume 73, Issue 3, Page 620-644, April 2026.ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.
