“…7). Thus, the early Lateglacial at 17-16 ka in the High Tatra Mountains was slightly wetter and warmer than in Central Alps but much colder and drier than in southern Europe (Makos et al, 2013a;Ivy-Ochs et al, 2006;Sarikaya et al, 2009). The first Lateglacial cold stage coincides well with other chronologies in the mountains of Europe (e.g.…”

“…Using cosmogenic radioisotope dating, Akçar et al (2007Akçar et al ( , 2008 found evidence that glacier expansion in the Kaçkar Mountains (NE Anatolia) started at ∼ 26 ± 1.2 ka BP and lasted until ∼ 18.3 ± 0.9 ka BP. Maximum glacier expansion occurred at ∼ 20.3 ± 1.5 ka BP in north-western Anatolia (Zahno et al, 2010), at ∼ 21.3 ± 0.9 ka BP in central Anatolia (Sarıkaya et al, 2009), and at ∼ 20.4 ± 1.3 ka BP in western Taurus (Arz et al, 2007); together with regional data from northern Anatolia: (c) δ 13 C from Sofular Cave (Fleitmann et al, 2009) reflecting changes in C3 and C4 plants and from Black Sea core 25-GC1: (d) arboreal pollen record (%) and Quercus curve (thin line); (e) xerophytic biome (%) with smoothed curve (thick line; simple moving 20 points average) (please note the reverse scale); (f) temperate biome (%) with smoothed curve (thick line); (g) concentration of marine dinocysts and acritarchs (specimens cm −3 ); (h) concentration of freshwater algae (specimens cm −3 ).

Abstract. High-resolution pollen and dinoflagellate cyst records from sediment core M72/5-25-GC1 were used to reconstruct vegetation dynamics in northern Anatolia and surface conditions of the Black Sea between 64 and 20 ka BP. During this period, the dominance of Artemisia in the pollen record indicates a steppe landscape and arid climate conditions. However, the concomitant presence of temperate arboreal pollen suggests the existence of glacial refugia in northern Anatolia. Long-term glacial vegetation dynamics reveal two major arid phases ∼ 64-55 and 40-32 ka BP, and two major humid phases ∼ 54-45 and 28-20 ka BP, correlating with higher and lower summer insolation, respectively. Dansgaard-Oeschger (D-O) cycles are clearly indicated by the 25-GC1 pollen record. Greenland interstadials are characterized by a marked increase in temperate tree pollen, indicating a spread of forests due to warm/wet conditions in northern Anatolia, whereas Greenland stadials reveal cold and arid conditions as indicated by spread of xerophytic biomes. There is evidence for a phase lag of ∼ 500 to 1500 yr between initial warming and forest expansion, possibly due to successive changes in atmospheric circulation in the North Atlantic sector. The dominance of Pyxidinopsis psilata and Spiniferites cruciformis in the dinocyst record indicates brackish Black Sea conditions during the entire glacial period. The decrease of marine indicators (marine dinocysts, acritarchs) at ∼ 54 ka BP and increase of freshwater algae (Pediastrum, Botryococcus) from 32 to 25 ka BP reveals freshening of the Black Sea surface water. This freshening is possibly related to humid phases in the region, to connection between Caspian Sea and Black Sea, to seasonal freshening by floating ice, and/or to closer position of river mouths due to low sea level. In the southern Black Sea, Greenland interstadials are clearly indicated by high dinocyst concentrations and calcium carbonate content, as a result of an increase in primary productivity. Heinrich events show a similar impact on the environment in the northern Anatolia/Black Sea region as Greenland stadials.

Quaternary glaciation in the Mediterranean mountains: a new synthesis

The Mediterranean mountains were repeatedly glaciated during the Pleistocene. Glaciers were present in most of the major mountains areas from Morocco in the west to the Black Sea coast of Turkey in the east. Some mountains supported extensive ice caps and ice fields with valley glaciers tens of kilometres long. Other massifs sustained only small-scale ice masses, although this was the exception rather than the norm. Glaciers still exist today and there is evidence that small glaciers were a common sight in many regions during the Little Ice Age. The Mediterranean mountains are important for palaeoclimate research because of their position in the midlatitudes and sensitivity to changes in the climate regimes of adjacent areas including the North Atlantic. These mountains are also important areas of biodiversity and long-term biological change through the Quaternary ice age. All of this provided challenges and opportunities for Palaeolithic societies. This paper reviews the history of the study of glaciation in the Mediterranean mountains from pioneer nineteenth century observations through to the detailed geomorphological mapping and advanced geochronological datasets of recent times. We also review the current state of knowledge to frame the contributions presented in this volume. Lastly, this new synthesis then identifies outstanding research problems and assesses the prospects for new studies of glaciation in the Mediterranean mountains.
