.... Imaging between different traverses relies solely on this diffractive component. Many migration methods treat such contributions in approximation.. A final CDP-based image can deliver good to excellent data quality. We investigate here the effect of parameters such as the number of data planes...

... ABSTARCT Shallow seismic surveys were carried out for 520 1km in 3 bays viz., Jaigad, Ambwah and Verwada along the Maharastra coast in the western part of India In Total, 53 traverses Were run across the shelf perpendicular to the Coast upto about 20m water depth. These surveys were used...

... ABSTRACT Consideration is given to the hazard presented by moving ice islands. A review of ice island occurrences, as reported in the literature, is supplemented by details of our observations of several recently-discovered ice islands north of Ellesmere Island. Systematic traverses...

... ABSTRACT Regional traverses of 3045 nautical miles of 12 fold seismic reflection data and four detailed grids of 1419 nautical miles of 24 fold seismic refection data are reported for the Gulf of Mexico. This is the first phase of a Gulf of Mexico Tectonic Framework Study. Observations...

... a circular loop of wire l50-m in diameter laid on the lake bottom and excited by a 400-Hz AC generator as source. With the ship's position regulated by electronic navigation, concentric arcs were traversed about the loop to measure the radial magnetic field, Hr, and the tangential electric field, Et...

... ABSTRACT The thickness and a real extent of an offshore spoil dump have been determined using recently developed remote acoustic sensing techniques. Computer processing of multi-channel reflection acoustic data acquired during traverses over the dump site exhibit characteristic compressional...

... is then able to carefully select his collection points, photograph, and describe the rocks in place. TYPICAL DIVE Field procedure with the Shelf Diver was to run traverses across areas - thought to have subsea outcrops. The traverses were first run with a surface ship and precision depth recorder (PDR...
