(2003)New 27Al NMR data are presented in order to clarify the discrepancies in the interpretation of the previous 27Al Magic Angle Spinning (MAS) spectra from hydrous aluminosilicate glasses. The 27Al MAS data have been collected ...
-
(2001)Transient water table variation in an unconfined horizontal aquifer, lying between two canals located at different elevations above the impermeable barrier and receiving time varying recharge, is predicted by obtaining an ...
-
(2002)Soil saturation is known to be of crucial importance to denitrification and other nitrogen cycling processes within the riparian zone. Since denitrification potential generally increases towards the soil surface, water ...

(PANGAEA, 2018-04-10)Conductivity-Temperature-Depth (CTD) profiles measured along cross-river transects in the inner Lena Delta. Data was measured using a CTD 60M multiparameter probe (Sea & Sun Technology GmbH, Germany).

(1998)Relative changes in the level of Lake Baikal, amounting to hundreds of meters in Quaternary time, are well documented. Data presented here show that tectonic displacements of the lake outlet or former shoreline features ...
-
(2010)The seismic waves excited by the Mw 7.6 Olyutorskii earthquake that occurred on April 20, 2006 in the Koryak Upland gave rise to water-level changes in five wells situated in continental areas of Kamchatka at hypocentral ...
-
(2001)The rare earth element (REE) composition of an acidic spring discharging at pH 2.7 was studied in relation to the REE composition of selected extracts of the coal-bearing strata hydrologically above the discharge. The low ...
-
(2004)Based on specific features of the geological structure and hydrogeological conditions of the Mezen Syneclise, the trend and quantitative estimates of compositional changes of groundwaters in Vendian sandy–clayey rocks in ...
-
(2003)In this paper an attempt is made to present a distributed physiographic conceptual model that uses the principles of flow continuity and momentum. For this purpose, the watershed under study is divided into subwatersheds ...
-
(EDP Sciences, 2019)Geochemical conditions of the formation of various minerals were studied within the oligotrophic pine-shrub and sphagnum peat bog. It was shown that at least two complex barriers function within the peat deposit. These ...
-
(2004)The fast marching method (FMM) is a grid based numerical scheme for tracking the evolution of monotonically advancing interfaces via finite-difference solution of the eikonal equation. Like many other grid based techniques, ...
-
(2013)The work presents a review of natural-science representations on the rotary motion of matter and its piecewise structure. Development of dense GPS-networks allowed to experimentally confirm the concept of block structures ...
-
(2001)N-type earthquakes sometimes occur before the eruption of andesitic volcanoes, but their source mechanism has not been understood well. Their waveforms have stationary periods and decay slowly resembling to damped oscillation. ...
-
(2003)A process-based facies model for asymmetric wave-influenced deltas predicts significant river-borne muds with potentially lower quality reservoir facies in prodelta and downdrift areas, and better quality sand in updrift ...
-
(2003)A new formulation is presented to describe both the wavefield and the static coseismic deformation in depth-dependent elastic models generated by an a priori prescribed plane dislocation seismic source of finite dimensions, ...
-
WAVEFIELD EXTRAPOLATION AND AMPLITUDE-VARIATION-WITH-ANGLE MIGRATION IN HIGHLY DISCONTINUOUS MEDIA (2003)Current macromodel-based one-way wavefield extrapolation ignores the practical highly discontinuous character of rock formations. The main effects of this highly discontinuous behaviour on transmitted wavefields are ...
-
(2001)Wavefront healing is a ubiquitous diffraction phenomenon that affects cross-correlation traveltime measurements, whenever the scale of the 3-D variations in wave speed is comparable to the characteristic wavelength of the ...
-
(2004)Multiresolution wavelet analysis of self-potential signals and rainfall levels is performed for extracting fluctua- tions in electrical signals, which might be addressed to meteorological variability. In the time-scale ...
-
(2000)We performed spectral analysis of the record of relative geomagnetic paleointensity obtained at ODP Site 983, covering the time interval 0-1.1 Ma. The results confirm the presence of significant power at frequencies ...
