Dead Sea pollen provides new insights into the paleoenvironment of the southern Levant during MIS 6-5 doi Spatial Temporal

The paleoclimate of the southern Levant, especially during the last interglacial (LIG), is still under debate. Reliable paleovegetation information for this period, as independent evidence to the paleoenvironment, was still missing. In this study, we present a high-resolution pollen record encompassing 147-89 ka from the Dead Sea deep drilling core 5017-1A. The sediment profile is marked by alternations of laminated marl deposits and thick massive halite, indicating lake-level fluctuations. The pollen...

Holocene vegetation history of the southern Levant based on a pollen record from Lake Kinneret (Sea of Galilee), Israel doi Spatial Temporal

Lake Kinneret, also known as the Sea of Galilee and Lake Tiberias, is located in the northeast of Israel. At a lake level of 211 m b.s.l. (below mean sea level), the central basin is 43 m deep. The maximum length of the lake is 21 km (N–S) and its maximum width is 12 km (W–E). Lake Kinneret’s surface area is 166 km². A new 17.8 m long sedimentary core was drilled in 2010. Here, we present the entire palynological record from it, which covers the last ~ 9,000 years. Special emphasis is given to the natural...

Palaeoclimate Reconstruction in the Levant and on the Balkans Spatial

For an understanding of the climate system’s variability, knowledge of the past climate is essential. Continuous observations are not available for longer than the last 100 years, a period that is insufficient to understand the variability and sensitivity of the climate system. Since information of both is necessary to build good climate models, the reconstruction of the past climate is fundamental. With palaeoclimate reconstructions it is possible to get information about the past climate and the climate...

Three climatic cycles recorded in a loess-paleosol sequence at Semlac (Romania) – implications for dust accumulation in south-eastern Europe doi Spatial

Recent investigations of the Semlac loess section in the south-eastern Carpathian Basin, which is situated at an undercut slope position on the right bank of the Mureş River in its lower reaches (Banat region, western Romanian), are presented and discussed. Dating back to marine isotope stage (MIS) 10, the more than 10 m thick loess sequence includes four fossil soil-complexes developed in homogenous and relatively fine silty loess. Because of the good preservation of the sediment, Semlac is regarded as a...

Impacts of climate and humans on the vegetation in northwestern Turkey: palynological insights from Lake Iznik since the Last Glacial doi Spatial

The Marmara region in northwestern Turkey provides a unique opportunity for studying the vegetation history in response to climate changes and anthropogenic impacts because of its location between different climate and vegetation zones and its long settlement history. Geochemical and mineralogical investigations of the largest lake in the region, Lake Iznik, already registered climate-related changes of the lake level and the lake mixing. However, a palynological investigation encompassing the Late...

Paleolimnology of Lake Iznik (NW Turkey) during the past ~ 31 ka cal BP Spatial

Lake Iznik, situated in the Marmara region (NW Turkey), is an alkaline lake with about 300 km2 surface area, inserted in an area of typical Mediterranean climate. During the dry summer season, carbonates are precipitating from the water column. The endogen carbonate accumulation, e.g. aragonite, is expected to hold past climate information. A detailed understanding of the limnological system is required to differentiate site specific signals and responses to climatic forcing. Geochemical and mineralogical...

Genesis of loess-like sediments and soils at the foothills of the Banat Mountains, Romania - Examples from the Paleolithic sites Romanesti and Cosava doi Spatial

The Paleolithic sites Romanesti and Cosava, situated at the foothills of the Banat Mountains in Romania, provide an important testament of life of the first European modern humans (Homo sapiens sapiens) during the Middle Pleniglacial. Even though these sites have been extensively excavated, little is known about the site formation of related loess-like sediments and soils. First luminescence data at the two investigated sections confirm sediments from the penultimate glacial period to the Holocene. ...

Late Quaternary ecosystem and climate interactions in SW Balkans inferred from Lake Prespa sediments Spatial

The transboundary Lake Prespa and its watershed enclose a remarkable biodiversity that is protected by several national and international treaties. Situated at 849 m a.s.l., the area is characterized by a transitional climate and the closed nature of the basin controls Lake Prespa’s modern hydrology. An 18 m-long sediment sequence was retrieved from a distal location, away from stream inflow, where preliminary hydroacoustic investigations suggested undisturbed sedimentation. Consequently, the sediments were...

A Late Glacial to Holocene record of environmental and human variability derived from a sediment record from Lake Dojran (Macedonia, Greece) doi Spatial

A Late Glacial to Holocene sediment sequence (Co1260, 717 cm) from Lake Dojran, located at the boarder of the F.Y.R. of Macedonia and Greece, has been investigated to provide information on climate variability in the Balkan region. A robust age-model was established from 13 radiocarbon ages, and indicates that the base of the sequence was deposited at ca. 12 500 cal yr BP, when the lake-level was low. Variations in sedimentological (TOC, CaCO3, TC, N, S, grain-size, XRF, δ18Ocarb, δ13Ccarb, δ13Corg) data...

Climatic and environmental evolution of Lake Iznik (NW Turkey) over the last ~4700 years doi Spatial

Magnetic susceptibility, geochemistry, mineralogy and palynology of sediments from Lake Iznik in Northwestern Anatolia, Turkey, provide a 4700 year record of climatic trends and events. The measured proxies allow a reconstruction of variations in humid/dry periods and lake level changes. The Lake Iznik sedimentary sequence points to an oscillating trend of humid periods interrupted by rapid climate change (RCC) to arid periods. Especially abrupt lithologic and geochemical changes at 4.2 and 3.3 ka calBP may...

Holocene climate variability in the Levant from the Dead Sea pollen record doi Spatial Temporal

The Dead Sea, located at the deepest place on continent and between the subtropical Mediterranean zone and the desert, reflects in its water composition and levels, and sedimentary records the hydrological conditions in the southern Levant region. Temporal variations in rainfall and temperatures of the Holocene Levant are reconstructed here from pollen data recovered from a sediment core drilled at the Ein Gedi shore, applying a novel biome model based on Bayesian statistics. Our results suggest that the...

Climate variability over the last 92 ka in SW Balkans from analysis of sediments from Lake Prespa Spatial

The transboundary Lake Prespa (Albania/former Yugoslav Republic of Macedonia/Greece) has been recognized as a conservation priority wetland. The high biodiversity encountered in the catchment at present points to the refugial character of this mountainous region in the southwestern Balkans. A lake sediment core retrieved from a coring location in the northern part of the lake was investigated through sedimentological, geochemical, and palynological analyses. Based on tephrochronology, radiocarbon and...
