Der Rodderberg-Krater bei Bonn
(E&G – Quaternary Science Journal; Vol.59, No. 1-2)Der mittelpleistozäne Vulkankomplex des Rodderbergs südlich von Bonn birgt vermutlich ein höchst wertvolles Klimaarchiv von regionaler und überregionaler Bedeutung. Er sitzt der aus dem älteren Mittelpleistozän stammenden ... -
Geologie, Paläontologie und Geochronologie des Eem-Beckens Neumark-Nord 2 und Vergleich mit dem Becken Neumark-Nord 1 (Geiseltal, Sachsen-Anhalt)
(E&G – Quaternary Science Journal; Vol.59, No. 1-2)Den Schwerpunkt dieser Arbeit bilden die Ergebnisse sedimentologischer, palynologischer, malakologischer und chronometrischer Untersuchungen an Sedimenten aus dem Zentralbereich des Paläoseebeckens Neumark-Nord 2. Die ... -
Impact of an 0.2 km3 Rock Avalanche on Lake Eibsee (Bavarian Alps, Germany) – Part II: Catchment Response to Consecutive Debris Avalanche and Debris Flow
(Earth Surface Processes and Landforms, 2020-11-16)The ~0.2 km3 Eibsee rock avalanche impacted Paleolake Eibsee and completely displaced its waters. This study analyses the lake impact and the consequences, and the catchment response to the landslide. A quasi‐3D seismic ... -
Large‐scale mass movements recorded in the sediments of Lake Hallstatt (Austria)–evidence for recurrent natural hazards at a UNESCO World Heritage site
(Journal of Quaternary Science, 2022-08-28)The Bronze to Iron Age underground salt mining complex of Hallstatt (Austria) is widely recognised for its cultural importance and wealth of archaeological artefacts. However, while the daily life in the salt mines is ... -
Lateglacial and Holocene environmental history of the central Kola region, northwestern Russia revealed by a sediment succession from Lake Imandra
(Boreas, 2020)Bolshaya Imandra, the northern sub-basin of Lake Imandra, was investigated by a hydro-acoustic survey followed by sediment coring down to the acoustic basement. The sediment record was analysed by a combined physical, ... -
Leaf Wax Hydrogen Isotopes as a Hydroclimate Proxy in the Tropical Pacific
(Journal of Geophysical Research: Biogeosciences, 2021-03-25)Hydrogen isotope ratios of sedimentary leaf waxes (δ2HWax values) are increasingly used to reconstruct past hydroclimate. Here, we add δ2HWax values from 19 lakes and four swamps on 15 tropical Pacific islands to an updated ... -
Limnological response to the Laacher See eruption (LSE) in an annually laminated Allerød sediment sequence from the Nahe palaeolake, northern Germany
(Boreas, 2020)This paper presents evidence for a limnological response to the Laacher See eruption (LSE) as detected in lake sediments from Nahe, northern Germany. The sediment section of the Allerød period dating to between 13 422 and ... -
Multiproxy-Untersuchungen zur Paläoökologie und -hydrologie eines spätglazial- bis frühholozänen Flachsees im nordostdeutschen Küstengebiet (Glowe-Paläosee/Insel Rügen)
(E&G – Quaternary Science Journal; Vol.65)The paper presents results of multiproxy-investigations of a 3 m long sediment section from the Glowe Palaeolake, covering the period Pre-Bølling to the middle of the Preboreal. The Lateglacial and early Holocene landscape ... -
Nano-Magnetite Aggregates in Red Soil on Low Magnetic Bedrock, Their Changes During Source-Sink Transfer, and Implications for Paleoclimate Studies
(Journal of Geophysical Research: Solid Earth, 2020)Soil and lake sediments are important paleoclimate archives often forming a source-sink setting. To better understand magnetic properties in such settings, we studied red soil on low-magnetic bedrock and subrecent sediments ... -
New insights into lake responses to rapid climate change: the Younger Dryas in Lake Gościąż, central Poland
(Boreas, 2020-12-16)The sediment profile from Lake Gościąż in central Poland comprises a continuous, seasonally resolved and exceptionally well‐preserved archive of the Younger Dryas (YD) climate variation. This provides a unique opportunity ... -
Precipitation and Lake Water Evaporation Recorded by Terrestrial and Aquatic n‐Alkane δ2H Isotopes in Lake Khar Nuur, Mongolia
(Geochemistry, Geophysics, Geosystems, 2022-02-17)The compound‐specific hydrogen isotopic composition (δ2H) of n‐alkanes is a valuable proxy to investigate hydrological conditions in lake sediments. While terrestrial n‐alkanes reflect the isotopic signal of the local ... -
Sediment imprint of the severe 2002 summer flood in the Lehnmühle reservoir, eastern Erzgebirge (Germany)
(E&G – Quaternary Science Journal; Vol.61, No. 1)Anhand von 18 Kurzkernen aus der Talsperre Lehnmühle (Inbetriebnahme 1932) im Osterzgebirge (Deutschland) wurden mittels mikrofaziellen und hochauflösenden μ-XRF Scanning Verfahren Auswirkungen des extremen Augusthochwassers ... -
The spatial distribution of sedimentary compounds and their environmental implications in surface sediments of Lake Khar Nuur (Mongolian Altai)
(Earth Surface Processes and Landforms, 2021-01-26)Lake sediments are valuable natural archives to reconstruct paleoclimate and paleoenvironmental changes which consist of inorganic and organic sediment compounds of allochthonous origin from the catchment and of autochthonous ... -
What Can We Learn From X-Ray Fluorescence Core Scanning Data? A Paleomonsoon Case Study
(Geochemistry, Geophysics, Geosystems, 2020)X-ray fluorescence (XRF) core scanning of marine and lake sediments has been extensively used to study changes in past environmental and climatic processes over a range of timescales. The interpretation of XRF-derived ... -
Why productive lakes are larger mercury sedimentary sinks than oligotrophic brown water lakes
(Limnology and Oceanography, 2020-12-25)Mercury accumulation in lake sediments is a widespread environmental problem due to the biomagnification of Hg in the aquatic food chain. Soil Hg concentrations, catchment vegetation, erosion, and lake productivity are ...
