Discovery of a cosmogenic 10Be anomaly during the late Miocene in deep-ocean ferromanganese crusts – an independent time marker for marine archives Open
Cosmogenic nuclide dating is a crucial tool in geochronology, relying on the consistent production and incorporation of radionuclides into geological archives. Deviations from this constancy, particularly during the Holocene or Pleistocene…

Potentials and limitations of using cosmogenic Beryllium isotopes for the synchronization of marine sediment and ice cores Open
Variations in the atmospheric production rate of cosmogenic 10Be lead to global changes in 10Be depositional fluxes. This may serve as a powerful tool for synchronizing various paleoclimate archives. For a robust synchronization, however, …

The first glaciers at Ivrea, southern Alpine Foreland  Open
Pleistocene Glaciations and their effects on Alpine topography have drawn scientific attention since well before the days of Penck and Brückner (1909), although this indomitable pair left a strong legacy to build upon. The onset of la…

Variations of the authigenic 10Be/9Be-ratio in marine sediments during the Laschamps event and their use for dating of marine sediments Open
The atmospheric production rate changes of cosmogenic 10Be are caused by variations of the Earth’s and Sun’s magnetic fields and are recorded worldwide in different climate archives (e.g. ice cores, marine/lacustrine sediments,…

Three Pleistocene glacial advances and a warm episode during MIS-3: Towards a more complete glacial history of the Pamir mountains Open
Determining the spatial and temporal variations of Pleistocene glaciations is key to understanding present-day climate-driven glacier changes. Glacial chronologies of high-mountain Asia, which are mostly based on cosmogenic 10Be exposure d…

A regional assessment of the deglaciation history of the Swiss Plateau based on newly obtained and re-evaluated Be-10 cosmic-ray exposure ages Open
During marine oxygen isotope stage (MIS) 2, the Swiss Plateau temporarily hosted large piedmont lobe glaciers that retreated after their maximum advance back to the fringe of the Alps. The presence of moraines in this region indicates that…
