High-resolution seismic profiles and petrographic data from surface and subsurface sediment samples from Mersin Bay, together with lithologic data from boreholes, were used to determine the origin and distribution of the pre- or early-Holocene unconformities in Mersin Bay (eastern Mediterranean). Reflectors corresponding to unconformities separate the younger, unconsolidated, marine transgressive sediments (Holocene) from the underlying, relatively coarser, consolidated sediments (Plio-Pleistocene). These unconformities correspond mainly to the erosional and subaerially deposited or later subaerially weathered land surfaces. These unconformities are probably related to the latest Pleistocene or earliest Holocene sea-level low stands.

Superficial deep-water sediments of the Eastern Marmara Basin Evans, G.; Erten, H.; Alavi, S. N.; Von Gunten, H. R.; Ergin, M. (Springer Science and Business Media LLC, 1989-3) Superficial sediments (top ∼ Im) of the Eastern Mediterranean Basin, Sea of Marmara, Turkey accumulated rapidly (0.087 ± 0.012 g/cm2 · y) by hemipelagic sedimentation with only limited amounts of gravity flow or bottom current action under low oxygenated but not anoxic conditions. They have restricted faunas, relatively higher organic carbon (1–1.8%) and lower calcium carbonate (14–20%) contents than other Eastern Mediterranean Basin sediments. Sedimentation shows little change over the last millenium excep...
SEISMIC STRATIGRAPHY OF THE FAULT-CONTROLLED SUBMARINE-CANYON VALLEY SYSTEM ON THE SHELF AND UPPER SLOPE OF ANAMUR BAY, NORTHEASTERN MEDITERRANEAN-SEA EDIGER, V; OKYAR, M; ERGIN, M (Elsevier BV, 1993-11-01) High-resolution shallow seismic reflection (Uniboom) and echosounding profiles obtained on the shelf and upper slope areas of Anamur Bay (Turkey, northeastern Mediterranean) were studied together with previous data on the onshore geology of the area to investigate the origin and related seismic stratigraphy of the submarine Anamur Canyon. It was found that the main axial trend of the submarine Anamur Canyon is aligned with the offshore projection of the N-S orientated, onshore Anamur thrust fault of Late Cr...
Effect of peak ground velocity on deformation demands for SDOF systems Akkar, S; Ozen, O (Wiley, 2005-11-10) The effect of peak ground velocity (PGV) on single-degree-of-freedom (SDOF) deformation demands and for certain ground-motion features is described by using a total of 60 soil site records with source-to-site distances less than 23 km and moment magnitudes between 5.5 and 7.6. The observations based on these records indicate that PGV correlates well with the earthquake magnitude and provides useful information about the ground-motion frequency content and strong-motion duration that can play a role on the s...
The role of mesoscale processes controlling biological variability in the Black Sea coastal waters: inferences from SeaWIFS-derived surface chlorophyll field Oguz, T; Deshpande, AG; Malanotte-Rizzoli, P (Elsevier BV, 2002-06-01) Several different time series of chlorophyll images from the 1997-2000 Seaviewing, Wide Field-of-view Sensor data set have been analysed to gain a perspective on the dynamical and biological variability in the Black Sea, particularly oil its northwestern shelf region and along the Anatolian coastal zone. The images are interpreted in terms of documenting the close link between biological production and physical dynamics of the boundary system, and of emphasizing the role of eddy processes on controlling mes...
Development of a geotechnical and geophysical database for seismic zonation of the Ankara Basin, Turkey Koçkar, Mustafa K.; Akgün, Haluk (Springer Science and Business Media LLC, 2008-07-01) Engineering geological and geotechnical site characteristics were assessed and seismic hazard studies performed for the Upper Pliocene to Pleistocene fluvial and Quaternary alluvial and terrace deposits for a site west of Ankara, Turkey. Sediment conditions were determined and a soil profile was characterized by surface geophysical methods. These studies were integrated with existing in-situ characterization studies to create a seismic and geotechnical database for the site. A seismic zonation map of the si...
