High Resolution Analysis of the Nature and Volume of Gas Hydrate and Carbonate Mineralization Across the Oregon Margin Accretionary Complex

提供资金用于对整个俄勒冈州增生复合体的天然气水合物和碳酸盐矿化的性质和体积进行高分辨率分析。这项研究将确定空间和体积的碳酸盐气体水合物和碳酸盐存在的走廊跨越水合物省的俄勒冈州边缘。侧扫声纳和高分辨率地震反射工作将绘制以ODP站点892为中心的地表和地下水合物。这些数据将允许评估液体排出的分布。此外，计划在2000米深处钻探100米岩心，以获取样品，对气相、孔隙沃茨、固体水合物和碳酸盐进行元素和同位素分析。岩心将通过新开发的便携式遥控钻机（PROD）获得。

Funds are provided for a high-resolution analysis of the nature and volume of gas hydrates and carbonate mineralization across the Oregon accretionary complex. The research will define spatial and volumetric carbonate gas-hydrate and carbonate presence in a corridor spanning a hydrate province of the Oregon margin. Side scan sonar and high-resolution seismic reflection work will map the surface and subsurface hydrates, centered on ODP site 892. These data will allow to assess the distribution of fluid venting. In addition, drilling of up to 100 m cores are planned in depths of 2000 m to obtain samples for elemental and isotopic analyses of the gas phase, pore waters, solid hydrate and carbonates. The cores will be obtained by a newly developed portable remotely operated drill (PROD).
