Quaternary climate change and Heinrich events in the southern Balkans: Lake Prespa diatom palaeolimnology from the last interglacial to present doi Spatial

Lake Prespa, in the Balkans, contains an important palaeo-archive in a key location for understanding Quaternary climate variability in the transition between Mediterranean and central European climate zones. Previous palaeoenvironmental research on sediment cores indicates that the lake is highly sensitive to climate change and that diatoms are likely to be strong palaeohydrological proxies. Here, we present new results from diatom analysis of a ca. 91 ka sequence, core Co1215, which spans the time from...

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...

Seen in der Sahara doi

Große Wasserflächen inmitten der Wüste sind nicht nur ein Naturspektakel, sondern auch ein hochpräzises Umweltarchiv. Die aus ihnen gewonnenen Sedimente dokumentieren die Klimaentwicklung und geben Aufschluss über Staubstürme, Savannenbrände und Vulkanausbrüche. Eine Reise in den Nordosten des Tschad. Von Stefan Kröpelin

Lakes in the Sahara doi

Large bodies of water in the middle of the desert are not only a natural spectacle, they also contain extremely precise environmental archives. Sediments extracted from these lakes document climate evolution and provide information on dust storms, savannah fires and volcanic eruptions. A journey to north-east Chad By Stefan Kröpelin

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...

Understanding past climatic and hydrological variability in the Mediterranean from Lake Prespa sediment isotope and geochemical record over the Last Glacial cycle doi Spatial

Here we present stable isotope and geochemical data from Lake Prespa (Macedonia/Albania border) over the Last Glacial cycle (Marine Isotope Stages 5-1) and discuss past lake hydrology and climate (TIC, oxygen and carbon isotopes), as well as responses to climate of terrestrial and aquatic vegetation (TOC, Rock Eval pyrolysis, carbon isotopes, pollen). The Lake Prespa sediments broadly fall into 5 zones based on their sedimentology, geochemistry, palynology and the existing chronology. The Glacial sediments...
