Pre-stack depth migrated multi-channel seismic images and velocity models of the sediment section near the Cascadia deformation front off Oregon and Washington, acquired during the R/V Marcus G. Langseth survey MGL1211 (2012)

This dataset contains the pre-stack depth-migrated MCS data along two transects across the Cascadia deformation front, offshore central Oregon near 44.6?N and Washington near 47.4?N acquired during the 2012 R/V Langseth survey. The seismic reflection images and seismic velocity of the two transects reveal contrasting deformation styles and consolidation states of the sediment section offshore central Oregon and Washington. Funded by NSF grants OCE10-29411 and 1457221.

本数据集包含2012年由朗塞斯号（R/V Langseth）研究船采集的叠前深度偏移多道地震（Multi-Channel Seismic, MCS）数据，这些数据沿两条横穿卡斯卡迪亚变形前缘的测线分布，采集区域分别位于俄勒冈州中部近海（约44.6°N）与华盛顿州近海（约47.4°N）。两条测线对应的地震反射图像与地震波速度数据，揭示出俄勒冈州中部近海与华盛顿州近海的沉积剖面具有截然不同的变形样式与固结状态。本数据集的采集工作受到美国国家科学基金会（National Science Foundation, NSF）项目OCE10-29411与1457221的资助。
