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.

本数据集收录了经处理的多通道地震（Multi-Channel Seismic, MCS）反射数据，这些数据采集自“尤因号（R/V Ewing）”执行的EW0207航次中针对胡安·德·富卡海岭的区域研究项目。本数据集内的文件均为叠后时间偏移反射叠加数据，可揭示地壳岩浆系统的特征，包括海岭轴部与轴山海丘下方垂直堆叠的岩浆岩床的赋存情况。数据处理流程的详细信息已在相关发表文献Carbotte等人（《地质学》，2020年）以及Carbotte等人（《地球物理学研究杂志》，2021年）中予以说明。数据文件采用SEG-Y格式存储。本研究的资助由美国国家科学基金会（NSF）的OCE 0002488和0648303两项拨款提供。
