Grain-Size Control on Petrographic Composition of Sediments: Compositional Regression and Rounded Zeros
(Mathematical GeosciencesMathematical Geosciences, 2009)It is well-known that sediment composition strongly depends on grain size. A number of studies have tried to quantify this relationship focusing on the sand fraction, but only very limited data exists covering wider grain ... -
Grain‐Size Distribution and Propagation Effects on Seismic Signals Generated by Bedload Transport
; ; ; ; ; (Water Resources Research, 2021-04-02)
Bedload transport is a key process in fluvial morphodynamics, but difficult to measure. The advent of seismic monitoring techniques has provided an alternative to in‐stream monitoring, which is often costly and cannot be ... -
Gran Paradiso — Mont Blanc: Prähistorische und historische Gletscherstände
(E&G – Quaternary Science Journal; Vol.16, No. 1)Das Untersuchungsgebiet umfaßt die westlichen und südlichen Teile der Aosta-Region vom Hauptkamm der M. Blanc-Gruppe bis zum nach N entwässernden Teil der Paradiso-Gruppe. Die Untergrenze bildet das Moränengebiet von ... -
Granitic dimensional stones in Uruguay: evaluation and assessment of potential resources
(Environmental Earth Sciences, 2012)In Uruguay commercial granite varieties comprise mafic rocks, granitoids, and syenitoids. There is a long tradition in Uruguay, as well as worldwide, of using dimensional stones in architecture and art, specially granitic ... -
Grassland greening on the Mongolian Plateau despite higher grazing intensity
; Sun, Zhanli; Ren, Yanjun; Schierhorn, Florian; (Land Degradation & Development, 2020-10-01)
Changes in land management and climate alter vegetation dynamics, but the determinants of vegetation changes often remain elusive, especially in global drylands. Here we assess the determinants of grassland greenness on ... -

Gravitationally Consistent Mean Barystatic Sea Level Rise From Leakage‐Corrected Monthly GRACE Data
; ; ; ; ; Thomas, Maik; ; (Journal of Geophysical Research: Solid Earth, 2020-11-19)
Gravitationally consistent solutions of the Sea Level Equation from leakage‐corrected monthly‐mean GFZ RL06 Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow‐On (GRACE‐FO) Stokes coefficients reveal that ... -
Gravitative Deformationserscheinungen aus dem Älteren Quartär der Leipziger Tieflandsbucht
(E&G – Quaternary Science Journal; Vol.44, No. 1)Am Beispiel eines im mitteldeutschen Braunkohlentagebau Schleenhain im Übergangsbereich Quartär/Tertiär aufgeschlossenen Profils weiden typische genetische Formen kryogen verursachter gravitativer Deformationen aus dem ... -
Gravity and magnetic investigations along the Peruvian continental margin
(Univ. Hamburg, 2002)This work presents the first three-dimensional gravity and magnetic investigation along the convergent Peruvian margin. Three-dimensional magnetic modelling is still a relatively untried and challenging technique. The ... -
Gravity Field Modeling Using Tesseroids with Variable Density in the Vertical Direction
; ; (Surveys in Geophysics, 2020-03-26)
We present an accurate method for the calculation of gravitational potential (GP), vector (GV), and gradient tensor (GGT) of a tesseroid, considering a density model in the form of a polynomial up to cubic order along the ... -
Gravity field modelling for the Hannover 10 m atom interferometer
; ; ; ; ; ; ; ; (Journal of Geodesy, 2020-11-27)
Absolute gravimeters are used in geodesy, geophysics and physics for a wide spectrum of applications. Stable gravimetric measurements over timescales from several days to decades are required to provide relevant insight ... -

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 ... -
