Processed pre-stack depth-migrated seismic reflection data from the 2018 SISIE seismic survey (MGL1803)

This data set presents processed Multi-Channel Seismic (MCS) reflection data in segy format. In the SISIE marine seismic experiment, seven major MCS profiles were acquired in 2018 with R/V Marcus Langseth during cruise MGL1803. The files in this data set are pre-stack depth-migrated reflections stacks with advanced processing routines applied. Details of the processing workflow are described in the linked data processing document. Note that profile MCS23AB is a merged version of lines MCS23A and MCS23B as described in the cruise report, while MCS17B and MCS17C were processed as separate lines. The data files are in SEG-Y format and were generated as part of the project called SISIE: South Island Subduction Initiation Experiment. Funding was provided through NSF grants OCE16-54689 and OCE16-54766.

本数据集展示了以 SEGY 格式处理的多元道地震（MCS）反射数据。在 2018 年，由 R/V Marcus Langseth 船在 MGL1803 航次中进行的 SISIE 海洋地震实验中，共采集了七个主要 MCS 轨迹。该数据集中的文件为预处理后的深度偏移反射叠加，并应用了先进的处理流程。处理工作流程的详细信息见相关数据处理文档。请注意，MCS23AB 轨迹是按巡航报告所述，将 MCS23A 和 MCS23B 轨迹合并而成，而 MCS17B 和 MCS17C 则作为独立的轨迹进行处理。数据文件采用 SEG-Y 格式，并作为名为 SISIE：南岛俯冲起始实验的项目的一部分生成。项目资金由 NSF 奖学金 OCE16-54689 和 OCE16-54766 提供。
