Processed Multi-Channel Seismic Data from the Galicia S Detachment, Northern Atlantic Ocean, acquired during the R/V Marcus G. Langseth expedition MGL1307 (2013)

A cooperative project between the U.S., U.K., Germany, Spain, and Portugal, this 2013 two-ship seismic experiment surveyed the Galicia Bank region off Iberia. F.S. Poseidon tended the OBS instruments while R/V Marcus G. Langseth fired the airguns. The goal was to collect data necessary to study the rifted continental to oceanic crust transition in the Deep Galicia Basin west of Spain. Workstation Loading Information (mgl1307.procInfo.pdf), rms velocity field (mgl1307.PSTM_Rms.segy) and eta parameter for VTI anisotropy (mgl1307.PSTM_Eta.segy) are available as a Related Documents. Funding was provided by the U.S. NSF (grants OCE10-31769, OCE10-30650, and OCE10-31769), the U.K. Natural Environmental Research Council (grants (NE/E016502/1 and NE/E015883/1), and the GEOMAR Helmholtz Centre for Ocean Research.本项目由美国、英国、德国、西班牙与葡萄牙联合实施，系2013年开展的双船地震勘探实验，对伊比利亚半岛外侧的加利西亚海台（Galicia Bank）区域完成了勘探作业。作业期间，F.S. Poseidon号负责运维海底地震仪（Ocean Bottom Seismometer，OBS）设备，R/V Marcus G. Langseth号则负责激发气枪震源。本实验的核心目标为采集必要数据，以研究西班牙以西的深海加利西亚盆地（Deep Galicia Basin）内裂谷型大陆地壳向洋壳的过渡特征。相关文档包括工作站加载信息文件（mgl1307.procInfo.pdf）、均方根速度场文件（mgl1307.PSTM_Rms.segy）以及VTI（垂直横向各向同性）各向异性eta参数文件（mgl1307.PSTM_Eta.segy）。本项目的资助方包括美国国家科学基金会（U.S. NSF，项目编号：OCE10-31769、OCE10-30650、OCE10-31769）、英国自然环境研究理事会（U.K. Natural Environmental Research Council，项目编号：NE/E016502/1、NE/E015883/1），以及亥姆霍兹基尔海洋研究中心（GEOMAR Helmholtz Centre for Ocean Research）。
