Ionic composition of precipitation in Marmaris station

Yücel, Gizem
In this study, wet-only rain samples were collected at a high-altitude rural site, by General Directorate of Meteorology, between July 2011 and November 2016. The sampling station was located at Marmaris Meteorological Radar, which has an altitude of 1000 m from sea level and located 15 km to the North of Marmaris. Collected samples were analyzed for major ions (SO42-, NO3-, NH4+, H+, Ca2+, Mg2+, K+ and Na+) by ion chromatography. Approximately 300 samples were collected and analyzed during study period. Residence time calculations showed that the station is under the influence of emissions at western Turkey and Balkan countries. Average pH of rainwater is 6.0 indicating extensive neutralization, which can be attributed to CaCO3, which is an abundant component in alkaline soil on the Mediterranean coast of Turkey. Neutralization of rainwater acidity is almost complete during summer period and decreases in winter, owing to limited resuspension of soil in winter. Trajectories of the station are grouped into 5 clusters, residence time analysis of trajectory segments with altitudes less than 500 m indicated that western parts of Turkey, Balkan countries, Ukraine and the Black Sea coast of Russia are potential source regions affecting composition of rainwater at Eastern Mediterranean. Most of the ions measured in this work have higher concentrations during summer season. The positive matrix factorization model revealed four factors, which were identified as two anthropogenic, one marine and one crustal factors. Potential source regions for the anthropogenic components in rainwater were identified as to be western Ukraine, Western Black Sea coast of the Turkey, Balkan Countries, North Africa and Georgia.


Chemical composition of precipitation at different parts of Turkey
Ayaklı, Gül; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2014)
In this study major ion composition of rain water samples collected at General Directorate of Meteorology Antalya, Balıkesir and Trabzon rain sampling stations were analyzed. The major ions SO42-, NO3-, NH4+, Cl-, Ca2+, K+ and Na+ were analyzed by ion chromatography. Data generated in these stations are compared to evaluate how chemical composition of rainwater changes as air masses travel on the Anatolian plateau. Data also demonstrate how rainwater composition varies seasonally at different parts of Turke...
Temporal and spatial changes of primary productivity the sea of Marmara obtained by remote sensing
İkis, Didem; Bilgin, Cemal Can; Department of Biology (2007)
Temporal and spatial variations in the Sea of Marmara based on monthly averages of chlorophyll a, which is the major indicator of phytoplankton biomass and primary production, recorded by SeaWiFS and MODIS-Aqua sensors at nearly 100 stations have been analyzed for the period of 1997-2007. Majority of phytoplankton blooms occur during the winter and spring seasons, followed by a smaller secondary bloom during the fall season. The majority of high magnitude blooms occur at the Eastern part of the Sea which ma...

Investigation of the Dependence of Satellite-Based Precipitation Estimate Errors to Distance from the Coastline In this study, Tropical Rainfall Measuring Mission (TRMM) 3B42 v7 satellite based rainfall data are verified by using cumulative monthly rainfall data measured at 257 stations operated by the General Directorate of Meteorology between 1998 and 2014. Long-term mean values of station-based and satellite-based rainfall data, correlation between them, Standard deviation of monthly average and anomaly ...
Akdeniz ve Karadeniz’deki kirletici Düzeylerini etkileyen kaynak bölgelerinin Belirlenmesi.
Güllü, Gülen; Günaydın, Gamze; Tuncel, Süleyman Gürdal (2001-10-01)
Potential source regions of trace elements and major ions measured in the Mediterranean atmosphere were investigated by combining trajectory statistics with emission data reported in the literature. The frequency of air mass transport from different wind sectors was investigated at three selected sites in the eastern Mediterranean, western Mediterranean and Black Sea basins. The upper air mass movements showed fairly similar general features at all three sites, with very small eastern, southeastern and sout...
Monitoring of chemical and isotopic compositions of geothermal waters along the North Anatolian fault zone
Süer, Selin; Güleç, Nilgün Türkan; Department of Geological Engineering (2004)
This study aims to determine the chemical (anion-cation) and isotopic compositions (d18O-dD-3H) of the geothermal waters along the North Anatolian Fault Zone (NAFZ) and highlight any possible seismicity-induced temporal variations during the course of two years (2002-2003) monitoring programme. The geothermal sites are alligned along a 800 km transect of the NAFZ and are, from west to east, Yalova, Efteni, Bolu, Mudurnu, Seben, Kursunlu, Hamamözü, Gözlek and Resadiye. The thermal waters of NAFZ are dominant...
