Late autumn–winter precipitation in northeast Turkey

January 27, 2012

Jex et al. published a short paper in Quaternary Research about speleothem-derived reconstruction of late autumn–winter precipitation in Gümüşhane, northeast Turkey. The observation goes back to ~ AD 1500 leading to the first long winter precipitation reconstruction for this region.

Holocene climate change in central Turkey

December 25, 2011

Last 6000 years climate record from Tecer Lake in central Turkey were published in Holoceneby Kuzucuoğlu et al. According to the mineralogy and grain-size distribution of lake sediments, during the mid-Holocene transition, intense droughts occured at the end of the sixth, fifth and fourth millennia BP. The characteristics of some climatic phases at Tecer seem specific to the location of the sequence which, when compared with other sites in the eastern Mediterranean, may record variations in the extent of different climatic systems.

Earthquakes cycles recorded in calcite veins

February 8, 2011

Uysal et al. 2011 have published a new study about long term seismic cycles recorded in southwest Anatolian calcite veins. The study appeared in the Journal of Earth and Planetary Science Letters. They conducted high-resolution micro-sampling, high-precision U-series dating and micro- chemical analysis on an extensional vein system in a tectonically active area. U/Th ages of the vein system is in between 23.9±0.2 ka and 11.8±0.2ka. Their study offers an innovative means of constraining the absolute timing of late Quaternary seismic and inter-seismic events in Anatolia, 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

 

Lake shrinkings from Southwest Turkey

July 1, 2010

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

Drought in the Fertile Crescent

June 14, 2010

Trigo et al. have published a study in the Journal of Agricultural and Forest Meteorology about the recent drought period (driest since 1940) in the Fertile Crescent (today’s south-eastern Turkey, eastern Syria, northern Iraq and western Iran). Precipitation decline was mostly noticeable over Iraq (up to 70%), with the suppression of rainfall particularly acute during 2007–2008. They characterized the drought in temporal and spatial scales and performed the first assessment on the associated impact in the hydrology, vegetation dynamics and cereal productions. They claimed a great impact on cereal production (wheat and barley) in the region and showed that the major grain-growing countries in the area (Syria, Iraq and Iran) were significantly affected by this drought, particularly in the year 2008. doi:10.1016/j.agrformet.2010.05.006

Sea level changes and vertical land movement in the Eastern Mediterranean

June 8, 2010

A new paper, published in the Quaternary International, provides new relative sea level data inferred from 13 archaeological sites along the coastal regions of Turkey and Israel. Anzidei et al. uses these archeological site positions with respect to the present sea level to measure of sea level changes for the last two millennial.
