Lateglacial and Holocene climate and environmental change in the northeastern Mediterranean region: diatom evidence from Lake Dojran (Republic of Macedonia/Greece) doi Spatial

The juncture between the west–east and north–south contrasting Holocene climatic domains across the Mediterranean is complex and poorly understood. Diatom analysis of Lake Dojran (Republic of Macedonia/Greece) provides a new insight into lake levels and trophic status during the Lateglacial and Holocene periods in the northeastern Mediterranean. Following a very shallow or even desiccated state at the core base at ca. 12,500 cal yr BP, indicated by sedimentological and hydro-acoustic data, diatoms indicate...

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...

Tephrostratigraphic studies on a sediment core from Lake Prespa in the Balkans doi Spatial

A detailed tephrostratigraphic record, which dates back to Marine Isotope Stage (MIS) 5b (ca. 91 kyr), has been established from a 17.76 m long core (Co1215) from Lake Prespa (Macedonia, Albania and Greece). A total of eleven tephra and cryptotephra layers (PT0915-1 to PT0915-11) were identified, using XRF scanning, magnetic susceptibility measurements, and macro- and microscopic inspection of the sediments. The major element composition of glass shards and/or micro-pumice fragments indicates that the...

North-south palaeohydrological contrasts in the central Mediterranean during the Holocene: tentative synthesis and working hypotheses doi Spatial

On the basis of a multi-proxy approach and a strategy combining lacustrine and marine records along a north–south transect, data collected in the central Mediterranean within the framework of a collaborative project have led to reconstruction of high-resolution and well-dated palaeohydrological records and to assessment of their spatial and temporal coherency. Contrasting patterns of palaeohydrological changes have been evidenced in the central Mediterranean south (north) of around 40° N of latitude, the...

Die Klima– und Umweltgeschichte des Balkans während des letzten Glazials und des Holozäns, rekonstruiert anhand von Seesedimenten des Prespasees (Mazedonien/Albanien/Griechenland) Spatial

Lake Prespa is one of the three largest lakes on the Balkan Peninsula and is, with a supposed age of more than three million years, one of the oldest lakes in Europe. The sediments of Lake Prespa constitute an invaluable climate archive for the Balkan region, which was sparsely inves-tigated. The focus of this study in the CRC 806 –Our way to Europe– is to reconstruct the cli-matic and environmental history of the Balkan region during the Late Glacial and Holocene on a high resolution. For this purpose, a...

Seasonal hydrochemical changes and spatial sedimentological variations in Lake Iznik (NW Turkey) doi Spatial

The Marmara region is a key area to investigate the interconnection and environmental changes between the Black Sea and the Eastern Mediterranean related to climate patterns. Lake Iznik is an oligohaline lake located in the southeast of the Marmara Sea. To decipher the long-term signals recorded in the sediment column requires better understanding of the processes in the modern lake environs. Seasonal limnological investigations were paired with geochemical and sedimentological analyses. Lake Iznik is an...

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...

Looking around Peştera Cu Oase: The beginnings of Upper Paleolithic in Romania Spatial

In contrast to the widely acknowledged anthropological finds in Oase Cave and to the key geographical position of Romanian territory for the assumed dispersion of Anatomically Modern Humans in Europe, the archaeological information regarding the emergence of the Upper Paleolithic in Romania remains poorly known to a broader scientific community. The prolonged theoretical and methodological isolation of the Romanian Paleolithic research has particularly contributed to keeping the regional archaeology out...

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...

Distinct lake level lowstand in Lake Prespa (SE Europe) at the time of the 74 (75) ka Toba eruption doi Spatial

The 74 (75) ka Toba eruption in Sumatra, Indonesia, is considered to be one of the largest volcanic events during the Quaternary. Tephra from the Toba eruption has been found in many terrestrial and marine sedimentary deposits, and acidity peaks related to the eruption have been used to synchronize ice core records from Greenland and Antarctica. Seismic profiles and sedimentological data from Lake Prespa on the Balkan Peninsula, SE Europe, indicate a lake level lowstand at 73.6 7.7 ka based on ESR dating...

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...

Late Pleistocene and Holocene contourite drift in Lake Prespa (Albania/F.Y.R. of Macedonia/Greece) doi Spatial

Hydro-acoustic surveys and coring campaigns at Lake Prespa were carried out between 2007 and 2009. This paper presents hydro-acoustic profiles and provide lithological and chronostratigraphical information from three up to 15.75 m long sediment sequences from the Macedonian side of the lake. The sediment sequences comprise glacial and interglacial sediments likely deposited from the end of Marine Isotope Stage (MIS) 5 to present day. The information implies a distinct change of sedimentation patterns at the...
