Expanding the Tephrochronological Record in the Alps: Discovery of the Laacher See Tephra in Lake Plansee (Austria) Open
We present the first documented occurrence of the Laacher See tephra (LST) in the Eastern Alps, identified in lake Plansee, Austria. The LST is a key chronostratigraphic marker for correlating and dating Late Glacial sedimentary archives. …

Cold mountain stream chironomids (Diptera) of the genus <i>Diamesa</i> indicate both historical and recent climate change Open
Chironomids of the genus Diamesa (Meigen, 1835, Diptera: Chironomidae) inhabit cold, oxygen-rich running waters. We have investigated the presence of Diamesa and other freshwater macroinvertebrates at 22 stream sampling sites in 3 European…

The exceptional find of a Bronze Age votive bog offering of millet accompanied by a human sacrifice. Or was it the other way around? Open
The first discovery of prehistoric human remains at the same wetland as millet plants (Panicum miliaceum), which is reported here for the Zahájí site in the Czech Republic, sheds curiously new light on the central European Middle Bronze Ag…

Lake Zapovednoe's Molten Fragments of Tunguska Airburst in 1908 Open
The Tunguska airburst occurred on June 30, 1908 and it was most likely caused by the impact of the Tunguska cosmic body (TCB). It is not clear what the origin of the TCB was as no impact craters or possible body remains have been found to …

Cryptotephra quantification in lake sediments: Two workflows developed for sites with distant Laacher See tephra fallout Open
Cryptotephra research has emerged as a major tool for determination of the age of sediments and unraveling the relationship between past volcanic events and their environmental impacts. Lacustrine deposits are particularly important for co…

Molecular and morphological characterisation of larvae of the genus Diamesa Meigen, 1835 (Diptera: Chironomidae) in Alpine streams (Ötztal Alps, Austria) Open
Diamesa species (Diptera, Chironomidae) are widely distributed in freshwater ecosystems, and their life cycles are closely linked to environmental variables such as temperature, water quality, and sediment composition. Their sensitivity to…

Energy status of chironomid larvae (Diptera: Chironomidae) from high alpine rivers (Tyrol, Austria) Open
Chironomids (non-biting midges) inhabit almost every wet or semi-wet continental environment on Earth with probably 10,000 different species. Species occurrence and composition are undoubtedly limited by environmental harshness and food av…

Paleomagnetic study on Holocene sediments from Upper Toporowy Lake in Tatra Mts, Poland Open
Here we present paleomagnetic investigations on sediments from Upper Toporowy Lake (local name: Toporowy Staw Wyżni), an infilled lake located on the Polish side of the Tatra Mountains. The sampling was done using a peat corer. A tota…

Suzdalevo Lake (Central Siberia, Russia)—A Tunguska Event-Related Impact Crater? Open
In 1908, a massive explosion known as the Tunguska Event (TE) occurred in Central Siberia. However, its origin remains widely discussed and environmental impacts are not known in detail. We investigated evidence of the TE in sediments of S…

Holocene spatio-temporal patterns of biomass burning in the Bohemian-Bavarian Forest Mountains (Central Europe) Open
<p>Long-term perspectives on disturbance dynamics are important for the conservation of protected areas, yet restoration and conservation strategies in the Bohemian-Bavarian Forest Mountains do not consider the long-term role and pat…

Two extreme events near the Allerød-Younger Dryas transition: A story read from Bohemian Forest lake sediments (Central Europe) Open
<p>Near 12,850 cal. yr. BP, the Younger Dryas cooling (YD) abruptly reversed the warming trend from the last glacial to the present interglacial at high northern latitudes. Subsequent YD-onset-related changes, including hydroclimate …

Identification of the Younger Dryas onset was confused by the Laacher See volcanic eruption Open
Structures from the Stone Age can provide unique insights into Late Glacial and Mesolithic cultures around the Baltic Sea. Such structures, however, usually did not survive within the densely populated Central European subcontinent. Here, …

Physical and geochemical proxy data and diatom stratigraphy in ~800-year sedimentary sequences from two shallow Arctic pond basins, Kobbefjord, SW Greenland Open
We present a multi-proxy dataset of two sediment cores (0.61 and 0.41 m long) from interconnected infilled depositional basins in the Kobbefjord area, southwestern Greenland. We performed analyses of magnetic susceptibility, grain size dis…
