Processed multichannel seismic data in the Woodlark Basin, acquired during the R/V Maurice Ewing survey EW9510 (1995)

This was an ODP site survey (prior to leg 180) to characterize the rift-to-spreading transition in the Woodlark Basin. The purpose was to study the structural and volcanic processes and the dynamics of the upper mantle that are associated with the splitting of continents. The lateral variation from continental rifting to seafloor spreading within the Woodlark Basin makes it an ideal area to investigate the active process of rifting and spreading center propagation into a continent. The results of this study will provide necessary site survey data with which to plan drilling in the Woodlark Basin. Funded by NSF grant OCE92-01691.

本次ODP（海洋钻探计划）现场考察（在180航次之前）旨在对伍德拉克盆地中裂谷至扩张过渡阶段进行特征描述。考察目的在于研究与大陆分裂相关的结构、火山作用及上地幔动力学过程。伍德拉克盆地内从大陆裂谷到海底扩张的横向变化，使其成为研究裂谷活动过程及其向大陆传播中心扩散的理想区域。本研究的成果将为规划伍德拉克盆地钻探提供必要的现场考察数据。该研究由NSF（美国国家科学基金会）资助项目OCE92-01691支持。
