Thi.s paper represents the results of a case study of the interaction between sea level rise (SLR), subsidence atid the consequences of this phenomenon on fresh water resources that may be subject to exacerbated salt-water intrusion. The possible reasons for rapid SLR at the permanent tide gauge station located on the southern coast of the Marmara Sea have been investigated based on time series data recorded since 1984. The population in the region relies mainly on groundwater resources for urban, tourism and agricultural water use, which represents a severe risk with regard to the replenishment of the coastal aquifer. Based on the findings, appropriate methods of assessing the coastal vulnerability to future SLR and recommendations for coastal zone management with emphasis on the protection of water resources are discussed.

This study assesses the level of background radiation for Kayseri province of Turkey. Natural radionuclide activity concentrations in soil samples were determined using high-resolution gamma spectroscopy. Outdoor gamma dose measurements in air at 1 m above ground level were determined using a portable gamma scintillation detector. The obtained results of uranium and thorium series as well as potassium ((40)K) are discussed. The present data were compared with the data obtained from different areas in Turkey. From the measured gamma-ray spectra, the average activity concentrations were determined for (238)U (range from 3.91 to 794.25 Bq kg(-1)), (232)Th (range from 0.68 to 245.55 Bq kg(-1)) and (40)K (range from 23.68 to 2718.71 Bq kg(-1)). The average activity concentrations of (238)U, (232)Th and (40)K were found to be 35.51, 37.27 and 429.66 Bq kg(-1), respectively, and 11.53 Bq kg(-1) for the fission product (137)Cs. The highest values of (238)U, (232)Th and (40)K concentrations (794.25 Bq kg(-1), 245.55 Bq kg(-1), 2718.71 Bq kg(-1), respectively) were observed in abnormal samples at Hayriye village. The average outdoor gamma dose rate in air at 1 m above the ground was determined as 114.43 nGy h(-1). Using the data obtained in this study, the average annual effective dose for a person living in Kayseri was found to be about 140.34 µSv.

Opinions and comments on the benthic foraminiferal assemblage observed around the mineral submarine spring in Kuşadası (Aydın, Turkey) mehmet baki yokes 1 , engin meric ‚ 2 , niyazi avs ‚ar 3 , i ‹pek barut 4 , seyfettin tas 4 , mustafa eryilmaz 5 , feyza dinc ‚er 6 and cu ¤ neyt bircan 7The aim of the study was to investigate the benthic foraminiferal fauna around the mineral water spring in Pamucak Cove, north-west Kuşadası (Aydın) and figure out the effects of the spring on the fauna. The spring was located 200 m off the coast at 12.4 m depth and its temperature was 19.68C. The study area was found to include a rich population of Red Sea originated Amphistegina lobifera, of which the distribution pattern is noteworthy. It is abundant in the centre of the spring and its close vicinity; its abundance decreases when getting away from the spring. It is more abundantly observed on the southern and western sides of the spring, whereas, it is outnumbered by Ammonia compacta and Elphidium crispum on the northern and eastern parts. The water currents around the spring were in north-south and north-west directions. The observed diverse diatom population around the spring constitutes the main food source and dispersal according to the currents may explain the reason for the abundance of the Amphistegina population on the southern and western sides of the study area. High abundances of A. lobifera have not yet been observed elsewhere in the Aegean Sea, although large populations of this species have been recorded on the south-west coasts of Turkey and in several stations on the south-east of Gokceada. Abundance of coloured individuals and Red Sea originated benthic species suggests the presence of special environmental as well as ecological conditions around the spring.
