(PANGAEA, 2018-09-24)Four automatic stations measuring soil temperature and VWC were deployed in the central Lena River Delta, Siberia in August 2013 and retrieved in August 2014. They were installed in a very shallow depth on the islands ...

-
(2001)Forsterite single crystals doped with vanadium were grown from melt using the Czochralski technique in various oxidation-reduction conditions: nitrogen, nitrogen with oxygen, argon, and argon with hydrogen atmospheres. The ...
-
(1996)We assess the potential of using foraminiferal calcite as a paleoceanographic indicator of seawater V concentrations. Laboratory culture experiments show that living benthic and planktonic foraminifera incorporate V into ...
-
(2003)The compatibility of vanadium (V) during mantle melting is a function of oxygen fugacity (fO2): at high fO2’s, V becomes more incompatible. The prospects and limitations of using the V content of peridotites as a proxy for ...
-
(2002)New measurements of partition of vanadium (V) between spinel, garnet and a pigeonite-like high pressure (P) pyroxene and magnesian liquids on the mantle solidus as a function of oxygen fugacity (fO2) are presented. The ...
-
(2004)We measured the adsorption of V(V) onto goethite (α-FeOOH) under oxic (PO2 = 0.2 bar) atmospheric conditions. EXAFS spectra show that V(V) adsorbs by forming inner-sphere complexes as VO2(OH)2 and VO3(OH). We predicted the ...
-
(2001)Seismograms recorded by the Global Seismic Network can be processed to obtain receiver strips for each earthquake. The receiver strips for all earthquakes can be analysed simultaneously in the time domain by using the ...
-
(1996)Dehydration-melting experiments from 10 to 20 kbar were performed on a metavolcanoclastic rock containing (in vol. %) biotite (16), amphibole (15) and epidote (13) in addition to plagioclase and quartz. At 10 and 12.5 kbar ...
-
(2002)Spatial patterns of soil in alpine tundra just above timberline may determine patterns of advance by woody species. Patterns of advance since the Little Ice Age show spatial aggregation. If soil resources have similar ...

VARIABILITY IN FAULT SIZE SCALING DUE TO ROCK STRENGTH HETEROGENEITY: A FINITE ELEMENT INVESTIGATION (2003)Practical application of fault size scaling relationships usually involves extrapolation of a limited data set over a scale range beyond that observed or into adjacent unstudied areas. Here we investigate the validity of ...
-
(2002)Fine-grained sediment waves have been observed in many modern turbidite systems, generally restricted to the overbank depositional element. Sediment waves developed on six submarine fan systems are compared using high-resolution ...
-
(1997)We have analyzed the stable carbon isotope ratios of various organic-walled microfossils preserved in marine sediments of Silurian and Devonian age. The aim of this study is to determine the amplitude of isotopic fractionations ...
-
(2004)Variability in sorbed water content was studied on several standard smectites, as dependent on the relative humidity (RH=0.5, 0.95 and 1.0), on temperature (constant 30 °C and variable room temperature) and on sorption ...
-
(2000)Three sediment cores from the Laptev Sea continental margin were investigated for their clay mineralogy by X-ray diffraction to study the fluvial sediment supply since the late Weichselian. In the study area, the clay-mineral ...

(PANGAEA, 2000-10-02)Three sediment cores from the Laptev Sea continental margin were investigated for their clay mineralogy by X-ray diffraction to study the fluvial sediment supply since the late Weichselian. In the study area, the clay-mineral ...
-
(2000)In order to reconstruct the depositional environment from the Laptev Sea continental slope and shelf during the past ~15,000 years BP maceral analysis was carried out on two sediment cores (PS2458-4, PS2725-5) and compared ...
