Impact of the Central American and the Indonesian seaways on the ocean circulation and oxygen minimum zone in the tropical Pacific Open
The tectonic change in geometry of two tropical seaways, the Central American Seaway (CAS) and Indonesian seaway, during the mid-Miocene to mid-Pliocene (~16-3 Ma BP) is thought as a key factor for the development of the present-day tropic…

Projections of hypoxia: Abiotic tracer-based insights into model parameter uncertainty Open
There is growing concern that global warming will lead to declining oxygen levels and the expansion of so-called "dead zones”. This endangers local ecosystems. Model-based projections are essential for assessing the impact of respect…

Holocene overbank sedimentation in Central Europe between natural and human drivers - The Weiße Elster River (Central Germany) Open
Up to several meters thick fine-grained Holocene overbank deposits are ubiquitously found in most Western and Central European lowland floodplains. However, despite their large importance for the geomorphological and geoecological floodpla…

Effect of an Open Central American Seaway on Ocean Circulation and the Oxygen Minimum Zone in the Tropical Pacific From Model Simulations Open
The tectonic closure of the Central American Seaway (CAS) during the mid‐Miocene to mid‐Pliocene (∼16–3 Ma BP) is thought of as a key interval for the onset of the present‐day tropical Pacific oxygen minimum zone (OMZ). In this study we in…

Ocean Oxygen: the role of the Ocean in the oxygen we breathe and the threat of deoxygenation Open
EMB Future Science Brief No. 10 highlights the most recent science on Ocean oxygen, including causes, impacts and mitigation strategies of Ocean oxygen loss, and discusses whether “every second breath we take comes from the Ocean”. It clos…

Late Weichselian–Holocene valley development of the Elbe valley near Dresden – linking sedimentation, soil formation and archaeology Open
Valley infills are essential for understanding changes in hydrology and landscape. Anthropogenic activities are proven by prehistoric settlement remains, which mark distinct sediments and soils as usable land during certain time periods. I…

No Consistent Simulated Trends in the Atlantic Meridional Overturning Circulation for the Past 6,000 Years Open
The Atlantic Meridional Overturning Circulation (AMOC) is a key feature of the North Atlantic with global ocean impacts. The AMOC's response to past changes in forcings during the Holocene provides important context for the coming centurie…

Effect of tectonic closure of the American Seaway on oxygen minimum zone in the tropical Pacific from model simulations Open
The world’s largest oxygen minimum zone (OMZ) resides in the eastern tropical Pacific where poorly ventilated “shadow zone”, created by stagnant tropical cyclonic gyre is complemented by intensive biological consumption o…

Holocene human-environmental interactions and seismic activity in a Late Bronze to Early Iron Age settlement center in the southeastern Caucasus Open
Long-term human-environmental interactions in naturally fragile drylands are an actual topic of geomorphological and geoarchaeological research. Furthermore, many prehistoric societies in drylands were also affected by seismic activity. Th…

Climate change disrupts core habitats of marine species Open
Driven by climate change, marine biodiversity is undergoing a phase of rapid change that has proven to be even faster than changes observed in terrestrial ecosystems. Understanding how these changes in species composition will affect futur…
