Processed multi-channel seismic reflection data from Axial Seamount and the Juan de Fuca Ridge (EW0207 seismic survey)

This data set presents processed Multi-Channel Seismic (MCS) reflection data acquired during a regional study of the Juan de Fuca Ridge conducted on R/V Ewing expedition EW0207. The files in this data set are post-stack time-migrated reflection stacks that reveal characteristics of the crustal magmatic system including the presence of vertically-stacked magma sills beneath the ridge axis and Axial Seamount. Details of the processing work flow are described in the associated publications Carbotte et al., (Geology, 2020) and Carbotte et al (JGR, 2021). The data files are in SEG-Y format. Funding was provided through NSF grants OCE 0002488 and 0648303.

本数据集展示了在R/V Ewing探险EW0207期间，对胡安·德富卡脊进行区域性研究时获取的经过处理的多个通道地震（MCS）反射数据。数据集中的文件为经过时移成像的反射剖面，揭示了地壳岩浆系统的特征，包括位于脊轴下方垂直叠置的岩浆岩床以及轴海山的详细信息。数据处理流程的详细描述见相关出版物Carbotte等（地质学，2020年）和Carbotte等（地球物理研究快报，2021年）。数据文件采用SEG-Y格式。该项目资金由NSF资助，资助编号为OCE 0002488和0648303。
