Sedimentary deposits in the Istanbul’s Byzantine harbour

January 27, 2012

Bony et al. published an interesting study in Quaternary International about a Byzantine harbour (Theodosian harbour) which has been uncovered during excavations in Istanbul. The stratigraphic sequence goes back to 7000 BP. In the marine part of the sedimentary sequence, the authors interpreted high-energy deposit as tsunami deposits and related to the earthquake of 557 AD.

Hydropower energy potential on Coruh River, Turkey

November 7, 2010

Muratli Dam on Coruh River (Source: Akpinar et al.)

A new review paper on hydropower energy potential of Turkey has been published by Akpinar et al. in Renewable and Sustainable Energy Reviews. Akpinar et al. investigated the hydropower plants in the Çoruh river basin, in the NorthEastern Turkey. There are total installed 37 dams and run of river (without storage) hydropower plants developed at various project stages, which corresponds 6.3% of total electricity energy production of Turkey.

Solar energy for sustainable future of Turkey

October 7, 2010

Solar energy map of Turkey (from Kaygusuz, 2010)

A review on solar energy potential of Turkey is published in the Journal of Renewable and Sustainable Energy Reviews by Dr. Kaygusuz from Karadeniz Technical University. He claimed in the paper that the Concentrating Solar Power (CSP) generation has the potential to become cost-effective energy production of Turkey in the future as the electricity demand of Turkey is rapidly increasing. Turkish government recently supporting the development of this type of technology strongly. For more details please go to doi:10.1016/j.rser.2010.09.042

 

Water quality in the Kucukcekmece Lake, Istanbul

September 27, 2010

A recent paper published by Taner et al., in the Journal of Ecological Indicators have discussed about the the Lagoon Water Quality Index (L-WQI) of Kucukcekmece Lake, a highly polluted watershed located in western metropolitan Istanbul by focusing on primary problems of the system such as increasing stress on aquatic biota, eutrophication and organic pollution. They used environmental indicators like dissolved oxygen saturation, total nitrogen to total phosphorus ratio, nitrate, orthophosphate, chlorophyll-a, chemical oxygen demand, pH, turbidity and electrical conductivity. The results from Küçükçekmece Lagoon were correlated with the observed water quality trends and reflect the impact of pollution in its tributaries.

Bronze age vegetation in the Middle East

August 22, 2010

by George Perfors

Deckers and Pessin have published a paper in the Quaternary Research about the Bronze age vegetation changes in the Middle Euphrates and Upper Jazirah (Syria and Turkey) based on more than 51,000 charcoal fragments of more than 380 samples from nine Bronze Age sites. Human impacts first took place within the riverine forests, and followed by land clearing within the woodland steppe. Local wood supplies at that time were still available despite the increased deforestation. For details, doi:10.1016/j.yqres.2010.07.007

Coastlines of Turkey

July 6, 2010

A new book chapter about the geomorphological features of Turkish coastlines appeared in the Encyclopedia of the World’s Coastal Landforms by Springer. It is the re-edited version of previously published chapter from The World’s Coasts: Online (2003) written by the famous geomorphologist Prof. Oguz Erol. It is a nice reference chapter to keep in mind. doi:10.1007/978-1-4020-8639-7_10.1

Coastline changes of Aksehir and Eber Lakes (SW, Turkey) have been investigated by Sener et al. from Suleyman Demirel University, Isparta, using multi-temporal satellite images since 1975. According to their results, published in the Journal of Water Resources Management, the surface area and volume of these two lakes have been decreased significantly. The Aksehir Lake was even dried up completely during the summer of 2008. doi:10.1007/s11269-009-9467-5
