Given the effects of steep dips and large lateral variations in seismic velocity beneath Vancouver Island continental shelf, processing travel time inversion are inadequate to obtain a detailed model subsurface. Therefore, full waveform is applied multichannel reflection data high-resolution Tofino fore-arc basin under shelf off margin. Seismic velocities obtained this study help understanding ...

The Cuatro Ciénegas Basin (CCB) is a rare oasis in the Chihuahuan Desert in the state of Coahuila, Mexico. It has a biological endemism similar to that of the Galapagos Islands, and its spring-fed ecosystems have very low nutrient content (nitrogen or phosphorous) and are dominated by diverse microbialites. Thus, it has proven to be a distinctive opportunity for the field of astrobiology, as th...

Advanced oxidation processes (AOPs) have led the way in the treatment of aqueous waste and are rapidly becoming the chosen technology for many applications. In this paper, COD reduction potential of leather tanning industry wastewaters by Electro-Fenton (EF) oxidation, as one of the AOPs, was experimentally evaluated. The wastewater sample was taken from an outlet of an equalization basin in a ...

Magnetotelluric (MT) data can image the Earth's electrical resistivity down to mantle but are rarely used for investigation of offshore rifted margins. In such settings, lower crust and upper altered by distinct tectono-thermal processes often display similar seismic velocities densities. By integrating models from MT data, we aim at resolving ambiguity. Here, 3D inversion long period, marine (...

in this research we have studied tabriz temperature inversion using radio-sound information, during the 2004-2008 periods in daily, monthly and seasonally scales. produced data associated with temperature inversion daily of the surface (2 meters) to 700 h.pa. several different measures are used, including the height of the base and the height of the top of the inversion, the temperature at the ...

State-of-the-art high resolution active remote sensing imaging radar, TerraSAR-X, is having all-weather and all-time data acquisition capability. It is a promising tool for mapping snow and glaciers in mountainous region. The current study has been done using dual polarization (HH/VV) Synthetic Aperture Radar (SAR) data of TerraSAR-X (TSX), to estimate the snow physical properties (snow cover, ...

The Middle-Chelif basin, in northwestern Algeria, is located a seismically active region. In its western part lies the El-Asnam fault, thrust fault responsible for several strong earthquakes. most important being earthquake (Ms = 7.3) of 1980. present study, ambient vibration data with single-station and array techniques were used to investigate dynamic properties ground estimate Vs30 structure...
