Seafloor deposits and deformations in shallow marine areas of a paleo-glacial area revealed by side-scan sonar data: a case study from Horseshoe Island, Western Antarctica

Denizhan Vardar, M. Korhan Erturaç, Orkan Özcan, Cem Gazioğlu

Abstract Advances in marine geophysical imaging, including high-resolution side-scan sonar and multibeam bathymetry integrated with ground-truthing methods (e.g., sediment sampling and underwater video observations), have substantially enhanced our ability to map submerged glacial landforms and reconstruct past ice-sheet dynamics. These techniques provide …

Spatiotemporal Evolution of Coastal Dune Systems in the Çukurova Delta Plain: A Multitemporal Analysis Using Historical Aerial Photographs and UAV-Based Photogrammetry

Semih Sami Akay, Orkan Özcan

Coastal dune systems are dynamic landforms shaped by aeolian processes, in which onshore winds transport and deposit sediments behind natural or artificial barriers. The Çukurova Delta Plain, Turkey’s largest delta along the Eastern Mediterranean, contains extensive dune fields, particularly within the Seyhan …
