Lay Summary (German)

Lead
Lay summary
Kleinasien ist im Klima der Nordhemisphäre eine interessante Schlüsselstelle; insbesondere ist dieses Gebiet eine sensible Schnittstelle verschiedener athmosphärischer Zirkulationsmuster. Wir untersuchen die Paläozirkulation über Anatolien anhand der Vergletscherung während der letzten Eiszeit und wollen insbesonders den Feuchtigkeitstransport der zu Gletschervorstössen geführt hat, rekonstruieren. Schwerpunkt unserer Arbeiten sind die Gebirge im NE der Türkei

Abstract

The geological records of paleoglaciations in Anatolia are one of the key archives to quantify paleoclimate change in the Eastern Mediterranean region. With our two project phases we have produced a data set on the timing and paleogeography of paleoglaciations in the Kaçkar Range of NE Anatolia, of the Western-Central Taurus and of Uludag (Fig. 2). However, there is not sufficient information available yet to link precisely the Alpine/Western Mediterranean cyclonic to the Eastern Mediterranean/Arabian/Asian monsoon paleocirculation pattern.We plan to supplement our data from the Kaçkar area by mapping and dating paleoglacial features to the south and southeast of Verçenik and Kavron Valleys (Fig. 3). This is necessary in order to reconstruct the paleogeography of former glaciers across the main weather divide as prerequisite for paleoprecipitation modeling. The reconstructions of the former ice-bodies by mapping trimlines and terminal moraine features will follow the methods used by Florineth (1998) and Kelly et al. (2002) in the Alps. The glacier reconstructions will be used to interpret paleocirculation patterns that nourished build-up of LGM-ice. And the resulting paleocirculation data are essential for, among others, NOAA’s experiments and models.With the detailed mapping program in the valleys of the southern Kaçkar Mountains (Fig. 3), we are collecting at least 110 samples from erratic boulders and/or glacially polished surfaces for exposure dating. The samples will be prepared by the PhD students under the supervision of Dr. Akçar for exposure dating in Bern and measured at the ETH/PSI Tandem AMS facility at Hönggerberg. In this context we benefit from the close cooperation with the surface exposure dating group at ETH and with the CRONUS program.This extension of our first two projects, we will also use the cosmogenic radionuclide 36Cl for the surface exposure dating. This method is well established as such and it is also routinely done at Bern in order to use others than quartz-bearing lithologies.The final academic product of the project will be two PhD-Thesis: N.N(A) and N.N(B) to be finished in spring 2012. The two candidates will begin in spring 2009 in order to enjoy a short overlapping time with Conradin Zahno for basic training. Our project relies substantially on Dr. Akçar’s highly respected reputation as a head of our SED-Laboratory, as co-supervisor of the PhD-students and as the liaison-person to our colleagues in Istanbul and Ankara.The scientific products of our project will be: (1) LGM ice reconstructions for the selected sites, produced by conventional field mapping and using a GIS-system for editing; (2) surface exposure dates of the LGM in the southern Kaçkar Mountains and of glacier events during the last glacial/interglacial transition, (3) maps of interpreted/inferred paleocirculation; (4) interdisciplinary papers in collaboration with archeologists and climatologists on the evolution of the physical environment of the Fertile Crescent in the eastern Mediterranean region; (5) cooperation within IGCP-521 “Black Sea - Mediterranean Corridor during the last 30 ka” and with the geoscience and paleoclimate community of Turkey.
