摘要： A method for identifying features in the Earth's subsurface below a body of water using transient controlled source electromagnetic measurements includes acquiring a plurality of transient controlled source electromagnetic measurements. Each measurement represents a different value of an acquisition parameter. Each measurement is indexed with respect to a time at which an electric measuring current source is switched. The plurality of measurements is processed in a seismic trace display format, in which each trace corresponds to the measurement acquired for a value of the acquisition parameter. A subsurface feature is identified from the processed measurements.

摘要： A method for determining the liquefaction tendency of a water saturated soil is provided in which a driven or self boring probe with a plurality of expanding and contracting bladders imposes a cyclic shear stress reversal on a body of soil in situ, and from the measurement of pore water pressure, the liquefaction potential of the soil can be quantified. A pore water pressure increase during cyclic shear stress reversals indicates a contractive soil which has the potential to liquefy. The method can also quantify the potential of electro-osmosis in preventing soil liquefaction, by energizing a group of at least three electrodes by a d-c power source during the potential onset of liquefaction, and measure the reduction in pore water pressure during subsequent repeated shear stress reversals imposed on the soil by the device.

摘要： The apparent electrical resistivities of various parts of a marine bottom (3) are determined by supplying an alternating electrical current to a pair of current supply electrodes and measuring potential differences between pairs of measuring locations. The locations are on a straight line on the marine bottom. There is a fixed ratio between the distance between the locations of each pair and the distance between said pair and the pair of current supply locations. Adjoining pairs of measuring locations have a measuring location in common. A flexible cable (1) for taking these measurements is described. The determined resistivities are subsequently compared with calculated resistivities to determine the compositions and thicknesses of the soil layers (4,5) of the marine bottom.

摘要： In order to increase result accuracy the noise effect during vessel motion is reduced, wherefore direct current pulses are excited the parameters of which are set basing on section conductivity and deposit depth, the electric field is measured simultaneously on pairs of receiving electrodes basing on the spatial averaging of potential of double electric layer that is generated on the boundary of electrode and water during the pulses and pauses between them, and geoelectrical parameters are determined. The device consists of an exciting field generating unit where a switchboard generates pulses on feeding electrodes, a generator consists of two parallel cable lines with emitting electrodes, a non-emitting ballast device that is a pair of alternating electric dipoles with equal moments, and a measuring unit with pairs of sectional receiving electrodes, the total length of an electrode section does not exceed 5% of the distance between the electrodes, and the connection between the electrode elements that are connected to the receiver line through a common input/output provides composition of the EMF that are generated in them.
