| Summary: | (target layer) consisted of simulated gas hydrates. The and randomly dispersed resistive nodules. The laboratory test and temperature conditions, gas molecules become encaged by be more appropriate for the detection of both thin resistive between the electrical properties of gas hydrates and ocean cm) and the "hydrate" content varied from 10% to 100% by conditions. The development of an electrical resistivity cone for the detection of gas hydrates in marine sediments could allow the in-situ detection of gas hydrates without crystalline substance. They have been found all over the design, fabricate and test an electrical resistivity cone dramatically affecting the surrounding temperature and due to their dependence on pressure and temperature gas hydrates in marine sediments are of concern to geotechnical engineers for several reasons, including: (1) hydrogenbonded oxygen atoms, forming a solid, ice-like in permafrost and tropical regions. The presence of natural inch (2.5 cm) and containing as little as 10% "hydrate" laboratory testing program consisted of pushing the cone layers and random resistive nodules. Layers as thin as 1 Natural gas hydrates are formed when, under certain pressure nodules were successfully detected using this configuration. of intact, in-situ samples of gas hydrates can be difficult pressure conditions. The objectives of this study were to results indicated that the four-electrode configuration may sediments, and (2) the effect that their dissociation has on sediments; (2) the resistivity module could be incorporated target layer thickness varied from 1 to 6 inches (2.5 to 15 the cone for use in the detection of thin resistive layers the engineering properties of ocean sediments. The recovery their effect on the load bearing properties of ocean through a three-layer soil profile in which the central layer using a two-electrode and four-electrode configuration. The volume. The objective was to determine the effectiveness of with standard cone penetrometer testing equipment; and (3) it world in both onshore and offshore environments, as well as would be ideal because: (1) there is a dramatic contrast |
