Probability Distributions of Radiocarbon in Open Linear Compartmental Systems at Steady‐State
(Journal of Geophysical Research: Biogeosciences, 2022-03-24)Radiocarbon (14C) is commonly used as a tracer of the carbon cycle to determine how fast carbon moves between different reservoirs such as plants, soils, rivers, or oceans. However such studies mostly emphasize the mean ... -
Probing quasar sight lines in three dimensions
(Univ. Potsdam, 2005)Strong damped Lyman alpha absorption (DLA) lines seen spectra of distant quasar are believed to arise when the sight line to the quasar goes trough the disc of a galaxy or a proto galaxy. Most of the neutral matter in the ... -
Probleme bei der modernen landwirtschaftlichen Moornutzung
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 13; 1983)Nahezu zwei Drittel aller Hochmoore und fast alle Niedermoore werden in Niedersachsen landwirtschaftlich − überwiegend als Grünland − genutzt. Aktuelle Nutzungsprobleme liegen z.Zt. innerbetrieblich im Bereich der Erhaltung ... -
Probleme der Kartierung und Systematik der Moorböden ‒ Eine Diskussion in Lingen und was bislang daraus geworden ist
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 24; 1994)Es wird über eine 1993 durchgeführte Diskussionsveranstaltung zum Thema einer bundeseinheitlichen Ansprache und Kartierung von Mooren berichtet. Ein wichtiges Ziel der Diskussionen (sowie einiger im Anschluß an die ... -
Probleme der Terrassenbildung
(E&G – Quaternary Science Journal; Vol.02, No. 1)Die meisten größeren Flüsse, z.B. Mitteleuropas, zeigen sich begleitet von einem ganzen System höherer Terrassen. Sind diese Terrassen, soweit nicht überhaupt tektonische Entstehung angenommen wird, glazialen oder ... -
Probleme des Gebirgsbaues und der Morphogenese auf der Insel Kreta
(Schulz, Freiburg im Breisgau, 1958)Zwischen dem Bau eines Gebirgslandes und seiner Morphogenese, d. h. der Entwicklung seiner Reliefeigentümlichkeiten, seines Formenstils, bestehen enge Beziehungen. Man kann keine morphologische Forschung betreiben, ohne ... -
Probleme im Artenschutz des Feuchtgrünlandes auf Niedermooren in Schleswig-Holstein
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 20; 1990)Extensiv genutztes-Feuchtgrünland hat in unserer Kulturlandschaft eine große Bedeutung für den botanischen Artenschutz. Sein Arteninventar ist heute aufgrund der Intensivierung der landwirtschaftlichen Nutzung, andererseits ... -
Problems of landslide chronology in the Mátra mountains in Hungary
(E&G – Quaternary Science Journal; Vol.47, No. 1)Im letzten Jahrzehnt wurden bei der Untersuchung der Rutschungsprozesse und -formen in Ungarn in den Mittelgebirgen, die zumeist in der Mitte und am Ende des Miozäns entstanden sind, viele Rutschungsformen aufgenommen. Als ... -
Problems related to the taxonomic placement of incompletely preserved amber fossils: transfer of the Paleogene liverwort Cylindrocolea dimorpha (Cephaloziellaceae) to the extant Odontoschisma sect. Iwatsukia (Cephaloziaceae)
(Fossil Record, 2017)A revision of the Baltic and Bitterfeld amber fossils assigned to Cylindrocolea dimorpha (Cephaloziellaceae) has yielded evidence of the presence of multicellular, bifid underleaves, which have not previously been reported ... -
Proceedings International Symposium "The stability of tropical rainforest margins - linking ecological, economic and social constraints of land use and conservation"
(Universitätsverlag Göttingen, 2005-09)This proceeding volume results from the submitted abstracts of the international symposium “The Stability of Rainforest Margins: Linking Ecological, Economic and Social Constraints” held on September 19 – 23, 2005 in ... -
Process-Based Simulation of Aerosol-Cloud Interactions in a One-Dimensional Cirrus Model
(Journal of Geophysical Research: Atmospheres, 2020)A new microphysical cirrus model to simulate ice crystal nucleation, depositional growth, and gravitational settling is described. The model tracks individual simulation ice particles in a vertical column of air and allows ... -
Process-oriented analysis of aircraft soot-cirrus interactions constrains the climate impact of aviation
(Communications Earth & Environment, 2021-06-17)Fully accounting for the climate impact of aviation requires a process-level understanding of the impact of aircraft soot particle emissions on the formation of ice clouds. Assessing this impact with the help of global ... -
Processes governing the amplification of ensemble spread in a medium-range forecast with large forecast uncertainty
(Quarterly Journal of the Royal Meteorological Society, 2019)This study provides a process-based perspective on the amplification of forecast uncertainty and forecast errors in ensemble forecasts. A case from the North Atlantic Waveguide and Downstream Impact Experiment that exhibits ... -
Processes of Contaminant Removal in Fe0-H2O Systems Revisited: The Importance of Co-Precipitation
(The @open environmental journal, 2007)The mechanism of aqueous contaminant removal by elemental iron (Fe0) materials (e.g., in Fe0-H2O systems) has been largely discussed in the iron technology literature. Two major removal mechanisms are usually discussed: ... -

Processes of Stratification and Destratification During An Extreme River Discharge Event in the German Bight ROFI
(Journal of Geophysical Research: Oceans, 2020-08-15)Processes of stratification and destratification in the German Bight region of fresh water influence (ROFI) are investigated following an extreme river discharge event in June 2013. For this purpose, a high‐resolution ... -
Process‐Based Flood Risk Assessment for Germany
(Earth's Future, 2021-10-05)Large‐scale flood risk assessments are crucial for decision making, especially with respect to new flood defense schemes, adaptation planning and estimating insurance premiums. We apply the process‐based Regional Flood ... -
