-
(2001)The determination of ground surface temperature history (GSTH) from present borehole temperature defines an ill-posed inverse problem for which the required regularization must reflect the stochastic properties of both ...
-
(1999)Possibilities are discussed for the fast determination of seismic velocities in ocean-continent transition zones based on recordings of oceanic earthquakes, where a third phase (T-phase) arrives besides the ordinary P and ...
-
(2002)The characteristics of an end-member formula are defined as follows: (1) the chemical formula must be fixed no variable chemical components are possible (2) the end-member formula must be compatible with the crystal structure ...
-
(2003)As many particle-associated contaminants and nutrients are supply controlled, the question of particle source is crucial. In addition, sediment storage has important implications for the delivery and fate of pollutants. ...
-
(1996)This article is intended to evaluate the probabilities of occurrence of mainshocks immediately after the occurrence of possible foreshocks and propose an optimal prediction algorithm based on possible foreshocks along the ...
-
(2002)Ground penetrating radar (GPR) has been used as a tool to access information about ground subsurface features. Such information is very important for different types of studies, varying from those related to archeological ...
-
(2002)Although the impact of plantation forestry and ground-preparation drainage on headwater runoff response has been widely studied, there are remaining uncertainties concerning the time scale of changes, scale effects of ...

THE USE OF INSTANTANEOUS POLARIZATION ATTRIBUTES FOR SEISMIC SIGNAL DETECTION AND IMAGE ENHANCEMENT (2003)This paper introduces and discusses a new polarization filter which can aid interpretation of single or multichannel multicomponent seismograms. We define a measure of degree of polarization based on instantaneous polarization ...
-
(1996)The occurrence and development of thermal erosion are affected by many factors: climate, geomorphology, geology and geocryology. The paper presents a mathematical model which can be used to calculate the parameters of ...
-
(PANGAEA, 2002-05-05)Oil polluted and not oil polluted soils (crude oil hydrocarbons contents: 20-92500 mg/kg dry soil mass) under natural grass and forest vegetation and in a bog in the Russian tundra were compared in their principal soil ...
-
(2000)The use of Mössbauer spectroscopic data on the second-order Doppler (SOD) shift to determine the reduced isotopic partition function ratio (β-factor) has been considered by the example of iron. Using the relation between ...
-
(2002)We investigated the potential of using a 24-electrode resistivity imaging apparatus for rapid reconnaissance surveys for natural-aggregate accumulation. The surveys were first calibrated at sites with known geometry of ...
-
(1996)This paper presents the results of a multivariate analysis of changes in groundwater table and chemistry observed in wells and springs at the Petropavlovsk Geodynamic Site during 1986-1992. The objective was to identify ...
-
(2004)The use of the GPS radio occultation technique (GPS RO) for retrieving physical and chemical parameters of the Earth's atmosphere has been deeply and widely investigated over the last decade. The technique has proved to ...
-
(2003)Understanding the pathways by which event water contributes to stream stormflow provides insight into stormflow generation mechanisms. We analyze the impact of storm size on the relative contribution of event water to ...
-
(Общество с ограниченной ответственностью «Георесурсы», 2018)The work considers deposits 302-303 of the Kuakbashsky area of the Romashkino oil field. The deposits 302-303 are confined to the carbonate layer of the Bashkirian and Serpukhovian sediments of the Middle and Lower ...
-
(2002)The anisotropy of magnetic susceptibility (AMS) is often controlled by both ferromagnetic (sensu lato) and paramagnetic minerals. The anisotropy of magnetic remanence (AMR) is solely controlled by ferromagnetic minerals. ...
-
(2002)This study shows that the use of uniaxial recordings maintains the linear dependence of the low frequency displacements, with first polarities included, on the moment tensor components, and thus can be easily incorporated ...
-
(2001)The geochemical behavior of sulfur in magmas depends strongly on the oxidation state of sulfur, but this s not easily determined by standard analytical methods. We have measured XANES absorption spectra at the sulfur K-edge ...
-
(2001)The aim of this Editors’ Message is to highlight the merits of simple equilibrium formulae for analysing pumping test data. It is not the intention to argue that equilibrium approaches should replace the standard non-equilibrium ...
