Reconstructing the paleotopography beneath the loess cover with the aid of an electromagnetic induction sensor
Reconstructing the paleolandscape at a detailed scale is almost impossible by conventional procedures based on soil augerings. Therefore, the use of the electromagnetic induction sensor was evaluated as an alternative for mapping the depth
Prospecting frost-wedge pseudomorphs and their polygonal network using the Electromagnetic Induction Sensor EM38DD
The focus of this paper is on locating and mapping frost-wedge pseudomorphs using electromagnetic induction (EMI). The AA. used EMI at a test site in Belgium to develop a new methodology for locating near-surface frost-wedge pseudomorphs. Besides
Electromagnetic scattering from layer of finite length, randomly oriented, dielectric, circular cylinders over a rough interface with application to vegetation
Measuring water velocity in highly turbulent flows : field tests of an electromagnetic current meter (ECM) and an acoustic Doppler velocimeter (ADV)
Two field tests were completed to compare the performance of an electromagnetic current meter (ECM) with that of an acoustic Doppler velocimeter (ADV) in gravel-bed rivers. Research was particularly motivated by the need to measure flow properties
of rocks. Micro-resistivity, microgravimetry, electromagnetic and diagraphic sounding means permit detailed investigations of conditions at depth below the surface. (LW).
Extending airborne electromagnetic surveys for regional active layer and permafrost mapping with remote sensing and ancillary data, Yukon Flats Ecoregion, Central Alaska
The goal of this study was to map active-layer thickness (ALT) and the presence or absence of near-surface permafrost at 30-m resolution throughout the Yukon Flats Ecoregion (YFE) of central Alaska. The AA. 1) compiled airborne electromagnetic (AEM
field. High-frequency velocity measurements obtained using an array of electromagnetic current meters are combined with results from grid and transect sampling of bed sediments from 9 sites on 3 small upland rivers in N. Exmoor, U.K.
Ground Penetrating Radar (GPR) is a shallow geophysical exploration technique based on the reflection of electromagnetic impulses. It gives a continuous image of the subsurface, like reflection seismics. The strong attenuation of radar waves in most
and high stress gradients characterize the East African Rift Valley areas, the Afar triangle, and some of the swells e. g. Tibesti and Jebel Mara. Data from electromagnetic deep soundings, gravity and teleseismic delay time studies are incorporated
of hyperspectral imaging, radiometrics and electromagnetics. Remote sensing is also beginning to offer capacity in terms of close-range (
platforms, as well as briefly reviewing more traditional multispectral scanners, and radiometric and electromagnetic systems. Examples of the applications of these techniques are summarized and presented within the context of geomorphometric analysis
