Assessing Volcanic Controls on Miocene Climate Change
(Geophysical Research Letters, 2022-01-18)The Miocene period saw substantially warmer Earth surface temperatures than today, particularly during a period of global warming called the Mid Miocene Climatic Optimum (MMCO; ∼17–15 Ma). However, the long‐term drivers ... -
Contrasting State‐Dependent Effects of Natural Forcing on Global and Local Climate Variability
(Geophysical Research Letters, 2022-05-17)Natural forcing from solar and volcanic activity contributes significantly to climate variability. The post‐eruption cooling of strong volcanic eruptions was hypothesized to have led to millennial‐scale variability during ... -
Der quartäre Osteifel—Vulkanismus im Rahmen der Lößbildung—ein Beitrag zur Lößgenese
(E&G – Quaternary Science Journal; Vol.30, No. 1)Seit dem Mittelpleistozän ist im Laacher Vulkangebiet, einem räumlich präzise faßbaren Areal, ein intensiver Vulkanismus überliefert. Mittels Schwermineralanalysen und Korngrößenuntersuchungen an Lössen der engeren und ... -
Die Schädelkalotte des Neanderthalers von Ochtendung/Osteifel - Archäologie, Paläoanthropologie und Geologie
(E&G – Quaternary Science Journal; Vol.50, No. 1)In der Osteifel wurde in den Deckschichten einer Kratermulde der Wannenköpfe-Vulkangruppe bei Ochtendung die Schädelkalotte eines Hominiden im Zusammenhang mit drei Steinartefakten gefunden. Aufgrund der anatomischen ... -

Schwermineralverteilung und Alter pleistozäner mariner Sedimente in Mittelitalien
(E&G – Quaternary Science Journal; Vol.34, No. 1)In den südlichen Maremmen zwischen Civitavecchia und dem Monte Argentario gelang es, mittels der Schwermineralanalyse pleistozäne marine Sedimente unterschiedlichen Alters voneinander abzugrenzen. Anhand der Beschreibung ... -
Tephra Deposition and Bonding With Reactive Oxides Enhances Burial of Organic Carbon in the Bering Sea
(Global Biogeochemical Cycles, 2021-11-07)Preservation of organic carbon (OC) in marine sediments exerts a major control on the cycling of carbon in the Earth system. In these marine environments, OC preservation may be enhanced by diagenetic reactions in locations ... -
The Hidden Giant: How a rift pulse triggered a cascade of sector collapses and voluminous secondary mass‐transport events in the early evolution of Santorini
(Basin Research, 2022-04-19)Volcanic island sector collapses have the potential to trigger devastating tsunamis and volcanic eruptions that threaten coastal communities and infrastructure. Considered one of the most hazardous volcano‐tectonic regions ...
