This study was conducted to determine potential groundwater storage areas in the semi-arid Oltu Basin northeastern Turkey. The of basin analyzed by evaluating eight geographical factors: lithology, linear density, soil depth, land use, precipitation, geomorphology, slope, and drainage density. These factors were classified weighted using remote sensing, information systems (GIS), analytic hierarchy process (AHP). obtained data modeled ArcGIS software, a map created. results show that there...
ABSTRACT We apply Ground Penetrating Radar (GPR) to detect a prehistoric canoe at the Maoshan site, Zhejiang Province, China. A complex attribute analysis of GPR data allows enhancing precision in target detection and provides more details about burial environment. The depth bottom interface is detected integrity whole assessed through survey. Difficulties application dense sampling 2D pseudo 3D originate from micro‐topographical disturbance that specifically affects investigation results...
Abstract Ice cores in Antarctica and Greenland reveal ice-crystal fabrics that can be softer under simple shear compared with isotropic ice. Owing to the sparseness of ice regions away from divide, we currently lack information about spatial distribution its association flow. Radio-wave reflections are influenced by alignments, allowing them tracked provided recorded simultaneously orthogonal orientations (polarimetric measurements). Here, image variations thickness extent fabric across Dome...
ABSTRACT Radio-echo sounding (RES) can be used to understand ice-sheet processes, englacial flow structures and bed properties, making it one of the most popular tools in glaciological exploration. However, RES data are often subject ‘strip noise’, caused by internal instrument noise interference, and/or external environmental which hamper measurement interpretation. For example, strip result reduced power from bed, affecting quality ice thickness measurements characterization subglacial...
The 3-dimensional finite difference thermodynamic coupled model on Antarctic ice sheet, GLIMMER model, is described. An idealized sheet numerical test was conducted under the EISMINT-1 benchmark, and characteristic curves of sheets steady state were obtained. Based this, this simplified from a one to 2-dimensional one. Improvement method coordinate system proposed. Evolution flow simulated temperature field conditions. results showed that deriving conservation mass, momentum energy agree...
The Gamburtsev Subglacial Mountains are completely buried by the East Antarctic Ice Sheet and hence one of most enigmatic tectonic features on Earth. mountain range is underlain 50-60 km thick crust seismically fast Precambrian lithosphere, which over 200 thick. Here we present gravity aeromagnetic images derived from AGAP aerogeophysical survey, depth to magnetic source estimates a joint forward model along an independent passive seismic line investigate crustal structure Province. reveal...
Abstract The application of RES technology is the most important method for study inner structure on Antarctic ice sheet. multi‐polarization radar developed in recent years can deduce feature and changing rule COF sheet according to variation reflecting power different orientations, determine history stain stress further. It understand flow mechanism dynamic process explain law past, present future. In this paper we deduced 3‐D FDTD equations which were derived from Maxwell equation adapted...

Summary Electrical resistivity tomography (ERT) has become an important component in archaeological investigation, attracting more and attention of the researchers thus leading to continuous improvements survey. In order develop detailed subsurface images for prospection, a full 3-D ERT is indispensable, particularly when complex heterogeneity exists. our study, surveys with electrode configurations pole-pole, pole-dipole, dipole-dipole wenner were carried out 128 electrodes Ancient city...
The rheology and evolution of the polar ice sheet are deeply influenced by anisotropy crystals. Studying crystals can help to well understand predict behavior then sea level rising global climate change. In this paper, firstly, we deduce expression eigenvalues eigenvectors anisotropic media, which determined permittivity tensor geometry media. Then, analytic formulas reflection transmission coefficients derived directly matrix transformation. Some models with real parameters tested, they...
Abstract Within electrical resistivity tomography (ERT), the selection of arrays and electrode locations can effectively enhance resolution imaging. By properly selecting optimizing survey design, a better will be obtained with fewer electrodes configurations than traditional arrays. Previous work has demonstrated that optimized design using ‘Compare R’ method provide conventional This paper adds target-oriented modified original method. The first selects target area in comprehensive data...
