01.06.2021 - Speleothem deposits indicate phases of precipitation. So far only very few of such archives have been found in the today hyper-arid Saharo-Arabian Desert (SAD). Therefore, the Saquia…
01.06.2021 - The equilibrium oxygen isotope fractionation factor between calcite and water allows in principle to infer temperature variations from carbonate δ18O if carbonate formation occurred in…
20.05.2021 - Spring systems are efficient and fast precipitating non-marine carbonate factories, but they are also prone to (early) diagenesis. This study revisits the Y-10 core, taken at one of the…
11.05.2021 - Quantitative records on deep-water dynamics in the North Atlantic older than ~1 Myr are sparse and typically of low temporal resolution. Kim Jakob and her colleagues provide now a new…
04.05.2021 - Radiocarbon (14C) has become a valuable proxy in paleoclimate research on carbonate archives like corals or stalagmites. For the investigation of past climate change, reproducible and…
20.04.2021 - Laura Lütkes has successfully accomplished her Master thesis project in physics on the study of Nd-isotopes in cold-water corals along a transect of the eastern Atlantic Ocean from…
