Advances in understanding calcite varve formation: new insights from a dual lake monitoring approach in the southern Baltic lowlands
(Boreas, 2021-02-09)We revise the conceptual model of calcite varves and present, for the first time, a dual lake monitoring study in two alkaline lakes providing new insights into the seasonal sedimentation processes forming these varves. ... -
Aeolian sedimentation in the Rhine and Main area from the Late Glacial until the Mid-Holocene
(E&G – Quaternary Science Journal; Vol.59, No. 1-2)Äolische Sedimente (sandiger Löss, Flugsand) wurden durch pedologische und geochronologische Methoden (OSL) mit dem Ziel untersucht, hieraus Aussagen zur stratigraphischen Abfolge und zum Ablagerungsalter zu gewinnen und ... -
Aerobic methanotrophy within the pelagic redox-zone of the Gotland Deep (central Baltic Sea)
(Biogeosciences, 2012-12-05)Water column samples taken in summer 2008 from the stratified Gotland Deep (central Baltic Sea) showed a strong gradient in dissolved methane concentrations from high values in the saline deep water (max. 504 nM) to ... -
Aerosol-Cloud-Precipitation Interactions in the Context of Convective Self-Aggregation
(Journal of Advances in Modeling Earth Systems, 2019)We investigate the sensitivity of self-aggregated radiative-convective-equilibrium cloud-resolving model simulations to the cloud condensation nuclei (CCN) concentration. Experiments were conducted on a long (2,000-km × 120-km) ... -
After 100 years: a detailed view of an eumalacostracan crustacean from the Upper Jurassic Solnhofen Lagerstätte with raptorial appendages unique to Euarthropoda
(Lethaia, 2020)The Solnhofen Konservat-Lagerstätte yields a great number of remarkably preserved fossils of eumalacostracan crustaceans that help us understand the early radiation of several groups with modern representatives. One fossil ... -
Age and origin of groundwater resources in the Ararat Valley, Armenia: a baseline study applying hydrogeochemistry and environmental tracers
(Hydrogeology Journal, 2021-08-28)Within the Ararat Valley (Armenia), a continuously growing water demand (for irrigation and fish farming) and a simultaneous decline in groundwater recharge (due to climate change) result in increasing stress on the local ... -
Age constraints on faulting and fault reactivation: a multi-chronological approach
(International Journal of Earth Sciences, 2009)Movement within the Earth’s upper crust is commonly accommodated by faults or shear zones, ranging in scale from micro-displacements to regional tectonic lineaments. Since faults are active on different time scales and can ... -
Age Uncertainty in Recurrence Analysis of Paleoseismic Records
(Journal of Geophysical Research: Solid Earth, 2021-08-07)Determining the aperiodicity of large earthquake recurrences is key to forecast future rupture behavior. Aperiodicity is classically expressed as the coefficient of variation of recurrence intervals, though the recent trend ... -
Agent‐Based Modeling of Alternative Futures in the British Land Use System
(Earth's Future, 2022-11-02)Socio‐economic scenarios such as the Shared Socioeconomic Pathways (SSPs) have been widely used to analyze global change impacts, but representing their diversity is a challenge for the analytical tools applied to them. ... -
Agrarwissen bäuerlicher Gruppen in Mali, Westafrika - standortgerechte Elemente in den Landnutzungssystemen der Senoufo, Bwa, Dogon und Somono
(Dietrich Reimer Verlag, 1991)Im Rahmen dieser Arbeit wird die Frage verfolgt, ob nicht auch in den wechselfeuchten Savannenzonen der westafrikanischen Sahelländer Möglichkeiten für Ecofarming bestehen. Die Grundhypothese ist, daß bei vielen Savannenvölkern ... -
Agricultural Development and Land Use Change in India: A Scenario Analysis of Trade-Offs Between UN Sustainable Development Goals (SDGs)
(Earth's Future, 2020)India has the second largest population in the world and is characterized by a broad diversity in climate, topography, flora, fauna, land use, and socioeconomic conditions. To help ensure food security in the future, ... -
Agronomic suitability studies in the Russian Altai using remote sensing and GIS
(Univ. Dresden, 2007)Diese Doktorarbeit beschreibt Methoden und geeignete Anpassungen bereits existierender Lösungen, um auf zwei verschiedenen Wegen die Landeignung für die Tal- und Beckenregionen der Südsibirischen Altaigebirges innerhalb ... -
Agro‐ecology, resource endowment and indigenous knowledge interactions modulate soil fertility in mixed farming systems in Central and Western Ethiopia
(Soil Use and Management, 2021-02-26)Site‐specific soil fertility management requires a fundamental understanding of factors that modulate soil fertility variability in the local context. To verify this assumption, this study hypothesized that soil fertility ... -
Air quality co-benefits of ratcheting up the NDCs
(Climatic Change, 2020-04-18)The current nationally determined contributions, pledged by the countries under the Paris Agreement, are far from limiting climate change to below 2 ∘C temperature increase by the end of the century. The necessary ratcheting ... -
Airborne and ground level flask sampling for regional carbon budgets - the potential of multiple tracer and isotope analyses ; development of a new "Investigation Strategy" and of an improved "Sampling System"
(Univ. Hamburg, 2005)Aim of the study was to test the capability of multiple trace gas analyses for the assessment of regional carbon budgets. Therefore, air samples were taken by airborne and ground level activities during several field ... -
