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 ... -

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 ... -
