Greenhouse gas emissions from soils—A review
Oertel, Cornelius;
; Zurba, Kamal; Zimmermann, Frank; Erasmi, Stefan (Chemie der Erde - Geochemistry, 2016)
Soils act as sources and sinks for greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Since both storage and emission capacities may be large, precise quantifications are needed ... -
Greenhouse Gas Mitigation Potential of Alternate Wetting and Drying for Rice Production at National Scale—A Modeling Case Study for the Philippines
; ; ; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2022-05-09)
Worldwide, rice production contributes about 10% of total greenhouse gas (GHG) emissions from the agricultural sector, mainly due to CH4 emissions from continuously flooded fields. Alternate Wetting and Drying (AWD) is a ... -

Greigite (Fe3S4) Formation in Artificial Sediments via Solid‐State Transformation of Lepidocrocite
; ; (Geochemistry, Geophysics, Geosystems, 2022-08-12)
Greigite (Fe3S4) is a ferrimagnetic iron‐sulfide mineral that forms in sediments during diagenesis. Greigite growth can occur diachronously within a stratigraphic profile, complicating or overprinting environmental and ... -
Grobgeschiebestatistik als Hilfsmittel bei der Kartierung eiszeitlicher Halte
(E&G – Quaternary Science Journal; Vol.17, No. 1)Zu den Zielen der Eiszeitforschung gehört das Erfassen der Stillstandslagen des nordischen Inlandeises. Im Tiefland haben sich dabei Morphologie und Leitgeschiebestatistik bewährt. In mittelgebirgigen Landschaften setzen ... -

Groundwater exploration and management using Geophysics: northern region of Ghana
(Univ. Cottbus, 2006)Groundwater has been identified as the best source for rural water supply in most rural communities in the Northern region of Ghana because it eliminates the problems of water borne diseases which have affected communities ... -
Groundwater flow reversal between small water bodies and their adjoining aquifers: A numerical experiment
; ; ; (Hydrological Processes, 2023-05-24)
Abstract The countless kettle holes in the Late Pleistocene landscapes of Northern Europe are ...

Groundwater fluoride contamination in Coimbatore district: a geochemical characterization, multivariate analysis, and human health risk perspective
(Environmental Earth Sciences, 2021-03-15)In this paper, fluoride geochemistry and health risk of groundwater in Coimbatore district is studied. The order of dominance of ions were HCO3 > Cl > SO4 > CO3 and Na > Ca > Mg > K. Alkaline ... -
Groundwater Modeling Taking Into Account Probabilistic Uncertainties
(Freiberg Online Geosciences; Vol. 10.2003)Auf Basis der Finite-Elemente-Methode wurde ein 3-D-Grundwassermodell weiterentwickelt, das Dichteabhängigkeit berücksichtigt und für gesättigte und ungesättigte poröse Medien gilt. In das Transportmodul ist die ... -
Groundwater Responses to Earth Tides: Evaluation of Analytical Solutions Using Numerical Simulation
; ; (Journal of Geophysical Research: Solid Earth, 2022-10-04)
Harmonic Earth tide components in well water levels have been used to estimate hydraulic and geomechanical subsurface properties. However, the robustness of various methods based on analytical solutions has not been ... -

Growth and Decay of Northwestern Tropical Atlantic Barrier Layers
; ; (Journal of Geophysical Research: Oceans, 2021-05-02)
The growth and decay mechanisms of barrier layers in the northwestern tropical Atlantic are studied by investigating small‐scale processes embedded in the regional circulation of the tropical Atlantic using output from an ... -
Growth and water relations of riparian poplar forests under pressure in Central Asia's Tarim River Basin
; Lang, Petra (River Research and Applications, 2020)
The riparian forests in the Tarim Basin (NW China) are mainly composed of poplar species (Populus euphratica, Populus pruinosa). In the hyper-arid climate of this region, the trees are phreatophytes, which rely on access ... -

Growth of microaerophilic Fe(II)‐oxidizing bacteria using Fe(II) produced by Fe(III) photoreduction
; ; ; ; ; (Geobiology, 2022-01-11)
Iron(II) (Fe(II)) can be formed by abiotic Fe(III) photoreduction, particularly when Fe(III) is organically complexed. Light‐influenced environments often overlap or even coincide with oxic or microoxic geochemical conditions, ... -
Growth response of calcifying marine epibionts to biogenic pH fluctuations and global ocean acidification scenarios
; ; ; ; (Limnology and Oceanography, 2020-12-17)
In coastal marine environments, physical and biological forces can cause dynamic pH fluctuations from microscale (diffusive boundary layer [DBL]) up to ecosystem‐scale (benthic boundary layer [BBL]). In the face of ocean ... -
Großflächige Wiedervernässung des ehemaligen Durchströmungsmoores „Obere Schnöden“ im Pfrunger-Burgweiler Ried (Baden-Württemberg)
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 41; 2011)Abstract: Pfrunger-Burgweiler Ried (2600 ha) is the second largest peatland in south western Germany. In autumn 2010, the first section of the Obere Schnöden fen (235 ha) was rewetted as part of a large scale conservation ... -
