Methane distribution and oxidation across aquatic interfaces
… ecosystems are Arctic fresh water bodies and the Elbe estuary which represent interfaces between freshwater-terrestrial and freshwater-marine environments, respectively. Arctic water bodies are significant atmospheric sources of methane. At the same time the methane cycle in Arctic water bodies is …

The Influence of Changing Nutrients and Warming on Phytoplankton and its Interactions with Zooplankton in the North Sea
… German Bight, with localized increases near the Elbe estuary. SST explains part of the long-term Chl-a variability, but responses differ strongly in space. In situ analyses indicate that spring Chl-a peaked in the 1980s–1990s and has since declined, though higher values persist in southern inner …

Investigation of Planar Channeling Radiation on Diamond and Quartz Crystals at Electron Energies between 14 and 34 MeV and Probing the Influence of Ultrasonic Waves on Channeling Radiation
… first measurements of CR at the Radiation source ELBE of the Forschungszentrum Dresden-Rossendorf have been performed in the fall of 2003, where the most important attempt for an application of CR in radiobiological research was the optimization of its yield and spectral line width as well. Since …
