Evaluation of glaciation and glacial shapes using geographic information systems and remote sensing (Eastern Black Sea)

Geçen, Reşat
This study investigates the actual glaciers and the major properties of glacial landscapes (valleys, cirques and lakes) located over the Eastern Black Sea mountain chain using Geographic Information Systems (GIS) and Remote Sensing (RS) technologies. A database is created for each glacial feature that includes fundamental properties of each landscape. Data layers used in the study include digital and analog topographic maps, satellite images, geological maps and drainage maps. The studies carried out yielded identification of 93 glacial valleys (30 main, 63 tributary), 1222 cirques and 685 lakes. Several properties (length, size, aspect, elevation, slope, orientation, roundness, elongation) of each glacial landscape are investigated for the northern and southern parts separately. The frequency of each landscape is found to be more in the northern part of the area. Total area of the actual glacier is found as 0.43 to 0.53 km2 by two methods of remote sensing applications.


Relationship between settlement location and morphological landform : a GIS method applied to Çankırı province
Sürmeli, Biricik Gözde; Toprak, Vedat; Department of Geodetic and Geographical Information Technologies (2003)
This study aims to develop a method to investigate the relationship between settlement locations and the morphological landforms using geographical information systems (GIS). The method is applied to Çankiri province, a mountainous terrain, which is covered in seventy-seven sheets of topographic maps at 1:25.000 scale. Three databases are created and used in this study: 1) Settlement database comprising various topographic and landform attributes of 891 settlements, 2) Morphological landform database compos...
Measurement and evaluation of the hydrodynamics and secondary currents in and near a strait connecting large water bodies - A field study
Gueler, Isikhan; Yueksel, Yalcin; Yalçıner, Ahmet Cevdet; Cevik, Esin; Ingerslev, Christian (Elsevier BV, 2006-09-01)
The straits connect two large water bodies show highly strong and stratified currents related to meteorological, morphological and hydrodynamic conditions. In some cases, spatial and temporal changes of the stratified currents and their thickness, direction and magnitude are so complex. This complexity directly affects the circulation pattern in the region, water exchange between both ends of the straits and migration of fish species. In order to understand general characteristics of this kind of straits an...

The aim of this study is to the evaluate land use and the land cover changes of an abandoned coal mine in Central Anatolia. The mining activity in the region was started at 1987 and after working for 18 years, all the rights of the mine was passed to an another company which after a while the came up with no coal production since its concession was cancelled on February 2008. Unfortunately, during the life of the mine, there were no mine closure and reclamation activities on the field. There was only a limi...
Analysis of Plio-Quaternary deep marine systems and their evolution in a compressional tectonic regime, Eastern Black Sea Basin
Sipahioglu, N. O.; Karahanoğlu, Nurkan; Altıner, Demir (Elsevier BV, 2013-05-01)
Facies architecture of submarine fans and channel-levee complexes in the Eastern Black Sea Basin and their evolution from the Late Miocene until the present day are studied using a three-dimensional seismic data set covering an area of approximately 1161 km(2). The interpretation of the observations reveals the outcome of the changing interplay between rate of sedimentation and compressional tectonism in the area through time.
Investigation of Sea Surface Temperature (SST) Anomalies over Cyprus Area
Georgiou, Andreas; Akcit, Nuhcan (2016-04-08)
The temperature of the sea surface has been identified as an important parameter of the natural environment, governing processes that occur in the upper ocean. This paper focuses on the analysis of the Sea Surface Temperature (SST) anomalies at the greater area of Cyprus. For that, SST data derived from MODerate-resolution Imaging Spectroradiometer (MODIS) instrument on board both Aqua and Terra sun synchronous satellites were used. A four year period was chosen as a first approach to address and describe t...
