Накратко на български

Сталактитите и сталагмитите в пещера в Западна Турция разкриват промените в валежите и температурите през последните 6000 години. Тези данни помагат да се разбере как климатът е повлиял върху развитието на древните цивилизации и миграциите в региона.

Holocene climate reconstructions from western Anatolia based on speleothem data

Anatolia served as a crossroad for early human migration and was a key-region for the spread of agriculture into Europe and the development of major empires such as the Hittite and Ottoman. An in-depth understanding of Holocene climate variability in Turkey is thus critical to investigate to what extent climate has shaped major evolutionary and cultural transformations in the region. Main goal of this MSCA-IF project (host institution: METU) is to identify the driving factors of Holocene climate variability in western Turkey and its possible impacts on ancient civilizations, and to distinguish potential anthropogenic signatures in stalagmites. Specific research objectives are: 1) to select the best speleothems from the target caves and to establish a high-precision chronological framework using U-Th dating, 2) to reconstruct high resolution stable isotope (O, C) and trace element time series controlled by robust geochronology, 3) to investigate the stalagmite-forming CO2 degassing system in detail by combining geochemical signals of drip water/host rock/stalagmites and stalagmite microtextural characteristics, and 4) to constrain the geochemical signature of possible anthropogenic signals. This project develops precisely-dated and highly resolved (annual to multi-decadal) records of rainfall (and temperature) from the Sırtlanini Cave (western Turkey) covering the last ~6000 years for western Turkey, and possibly for the Eastern Mediterranean region.

Цел на проекта

Speleothems (calcareous cave deposits) are among the most useful archives that are utilized to reconstruct pastenvironmental conditions, including palaeotemperature and moisture conditions, on decadal to millennial timescales. Highquality(high-resolution, precisely dated, complete, and robust) regional speleothem-based palaeoclimate records,specifically revealing the past variability of rainfall regimes, is of great importance for human water, and hence for the futureestimations pertaining the human-climate-environment relationship. Research suggests that decreases in rainfall-drivenwater availability during the late Holocene in the Eastern Mediterranean region was one of the main reasons for the declineand/or collapse of some former civilizations (e.g., decline of Ottoman Empire in the preindustrial era, collapse of Uruk societyin Mesopotamia during the transition from chalcolithic to the early Bronze Age, societal collapse of the Late Bronze Age).This project will generate an extensive dataset through a multi-proxy approach of isotope and trace element geochemistryusing Holocene-aged stalagmites from several cave sites located in western and southwestern Anatolia (Turkey). The mainobjectives of the proposed action are: (1) to produce precisely-dated (U-series dating) and high temporal resolution paleorecordsconcerning the Holocene climate dynamics that affected the living patterns of ancient Aegean civilizations (e.g.,Classical Greek and Roman), (2) to trace possible impacts of human-induced environmental and atmospheric pollutionthrough a suite of high resolution stalagmite records, including stable isotope and trace element variations (e.g., changes incarbon and sulphur isotope ratios), and (3) to explore whether the speleothems reflect Holocene volcanic activities thatoccurred in the Aegean region, and if so, to distinguish these effects from anthropogenic activities.
