Ocean Bottom Seismometer (OBS) data across Hydrate Ridge, Cascadia convergent margin, northwest Pacific, acquired during the R/V Maurice Ewing survey EW0203 (2002)

This 3-D survey was conducted at the Hydrate Ridge, Cascadia convergent margin, northwest Pacific. The seismic experiment used the R/V <i>Maurice Ewing</i> and the <i>Joides Resolution</i> to collect multichannel seismic (MCS) data, vertical seismic profile (VSP) data, and ocean-bottom seismometer (OBS) data. This cruise was designed to acquire three sets of seismic data to map the elastic properties of gas hydrates. This was a three-part project to examine gas hydrate properties in the vicinity of an Ocean Drilling Program set of wells. Funded by NSF grant OCE0002487.

本三维地震勘探作业实施于西北太平洋卡斯卡迪亚汇聚边缘的水合物脊（Hydrate Ridge）。本次地震实验依托“莫里斯·尤因号研究船（R/V Maurice Ewing）”与“乔迪斯·决心号（Joides Resolution）”，采集了多道地震（multichannel seismic, MCS）数据、垂直地震剖面（vertical seismic profile, VSP）数据以及海底地震仪（ocean-bottom seismometer, OBS）数据。本次航次旨在获取三类地震数据，以绘制天然气水合物的弹性属性分布图。本项目分为三个子部分，用于研究大洋钻探计划（Ocean Drilling Program）井群周边的天然气水合物属性，由美国国家科学基金会（National Science Foundation, NSF）的OCE0002487号项目资助。
