In this study, the influence of synoptic-scale atmospheric transport patterns on observed levels of trace elements at Eastern Black Sea region of Turkey was examined. Daily PM2.5 samples were collected at station (40°32’34”N, 39°16’57”E) on the Eastern Black Sea region of Turkey and collected samples were analyzed with ICP-MS for trace element composition. Five-day long back trajectories for March 2011 to December 2013 were calculated for 3 different arrival heights, 100m, 500m and 1500m, and combination of these 3 arrival heights. Back trajectories of air masses arriving in Eastern Black Sea of Turkey were classified into distinct transport patterns by cluster analysis. Cluster Analysis grouped back trajectories into 10 clusters depending on their direction and speed. Measured concentrations of trace elements were assigned to clusters to examine their cluster to cluster variations. Kruskal Wallis test was used to test for significant differences in mean elemental concentration across clusters. Significant cluster to cluster differences were observed in levels of crustal, anthropogenic and mixed origin source elements

The experimental analysis on the Late Quaternary deposits of the Black Sea
Tekiroglu, SE; Ediger, V; Yemenicioglu, S; Kapur, S; Akca, E (Elsevier BV, 2001-01-01)
Holocene sediments taken from the south-eastern and western Black Sea have been investigated in relation to their geochemical, sedimentological and mineralogical characteristics. Their textures are characterized by their low amount of sand, upward-increasing silt and downward-increasing clay contents. While the terrigenous materials transported from Anatolian volcanic-based sources and European alluvial sediments form the shore deposits, the deep-sea sediments mainly consist of the marine biological product...
The diel vertical distribution of zooplankton in the southeast Black Sea
Erkan, F.; Gücü, Ali Cemal; Zagorodnyaya, J. (2000-01-01)
The diel changes in the vertical distribution of zooplankton in the southeast Black Sea were described in this study. The zooplankton were sampled using two different sampling methods throughout one day in October 1996 and July 1997 at the same station. The zooplankton counts, the length measurements and biomass estimates showed that the zooplankton in the southeast Black Sea is dominated by small organisms, among which Noctiluca scintillans is the dominant species. In the vertical distribution of zooplankt...
Estimation of phytoplankton biomass using HPLC pigment analysis in the southwestern Black Sea
Ediger, D.; Soydemir, N.; Kıdeyş, Ahmet Erkan (2006-01-01)
The phytoplankton population of the southwestern Black Sea in May 2001 was studied by taxonomic analysis using microscopic examination and by pigment analyses using high-performance liquid chromatography (HPLC). Pigment data, which identified phytoplankton assemblages dominated by dinoflagellates, diatoms and coccolithophores in May 2001, were compared to phytoplankton cell counts and biomass. There were significant (p < 0.002-0.01, r=0.56-0.67) relationships between the taxon-specific pigment concentration...
Examining the Lycian Sites by Using GIS
Aydın, Ervin Kenan; Toprak, Vedat; Department of Archaeometry (2006)
This study investigates the relationship between the ancient settlements (in Lycia) and physical environmental parameters including topography, rock and soil types using GIS. Modern settlements are also included in the study to analyze if the response has changed to these parameters from past to the present. The databases created in the study include three topographic attributes (elevation, slope and aspect), rock type, soil type, ancient settlements and modern settlements. Analyses performed in the study i...
