Direct evidence of active tectonics along the offshore sector of the Dinaric Fault System [PDF]

open access: yesScientific Reports
Tectonic deformation along the External Dinarides fold-and-thrust belt is slow, with transpressional crustal strain redistributed along multiple faults. Some of these faults reach the surface along the NE Adriatic coast as part of the strike-slip Dinaric

Seabed sub-bottom sediment classification using parametric sub-bottom profiler [PDF]

open access: yesNRIAG Journal of Astronomy and Geophysics, 2016
AbstractMany studies have been published concerning classification techniques of seabed surfaces using single beam, multibeam, and side scan sonars, while few paid attentions to classify sub-bottom layers using a non-linear Sub-Bottom Profiler (SBP). Non-linear SBP is known for its high resolution images due to the very short pulse length and aperture ...
