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 …

Evidence for the onset of the last Glacial Period at Barton Peninsula (King George Island, Antarctica): Luminescence (pIRIR) dating of glacial till underlying the Holocene patterned ground structures

Eren Şahi̇ner, M. Korhan Erturaç, Alper Gürbüz

ABSTRACT Understanding the long‐term Quaternary glacial history of the Antarctic Peninsula and South Shetland Islands is crucial for contextualizing ice sheet responses to climate change. While Holocene deglaciation is relatively well‐studied, direct terrestrial evidence for pre‐Last Glacial Maximum (LGM) events remains scarce. …

Advanced luminescence dating of the Karapürçek formation reveals middle pleistocene tectonic reorganization of the North Anatolian Fault Zone

Eren Şahi̇ner, M. Korhan Erturaç

This study establishes the first numerical age constraints for the Karapürçek Formation in northwestern Anatolia, Türkiye, using thermally assisted optically stimulated luminescence (TA-OSL) dating. This formation represents the sedimentary fill of a former pull-apart basin and thus records a critical phase in …

Geochemistry and Geochronology of Horseshoe Island (Antarctic Peninsula) Igneous Rocks

Raif Kandemir, Orhan Karslı, Hadi Shafaii Moghadam, Cüneyt Şen et autres

The geotectonic evolution of the Antarctic Peninsula (AP), one of the most important parts of the West Antarctic mosaic, began before the breakup of the Gondwana continent during the Triassic. The geotectonic events that formed the AP continued after the breakup. Horseshoe …

Timing of glacier retreat and spatio-temporal variations in the vertical deformation rate of the Horseshoe Island, Marguarite Bay, west Antarctic Peninsula

M. Korhan Erturaç, Eren Şahi̇ner, Raif Kandemir, Hilal Okur et autres

The Antarctic Peninsula is uplifting rapidly due to the isostatic response to ice sheet unloading since the Holocene. Understanding the timing and rate of this process is crucial for addressing several key research questions: (1) exploring the elastic interactions between the mantle …

Reconstructing the relative sea level of the Black Sea during the last glacial period

Eren Şahi̇ner, M. Korhan Erturaç, Raif Kandemir, Konstantin Kostov et autres

The Black Sea is currently a nearly enclosed basin connected to the Mediterranean via the Bosphorus Strait (sill depth at 35 m bsl), the Marmara Sea, and the Dardanelles (65 m bsl). During the last glacial period, this connection was severed due …
