On-shore data of the amphibious part of the refraction-seismic project INGON in and around Sri Lanka (RV SONNE cruise SO258/2)

In July and August 2017, off-shore seismic measurements have been carried out south of Sri Lanka as part of the INGON project. Main aim of this part of the project was to study the deep structure of the continent-ocean transition south of Sri Lanka and the early plate drift of India and Sri Lanka. The marine profile was extended by 15 seismic stations on-shore Sri Lanka, of which the data is contained in this data publication (land observations of airgun sources). This dataset consists of the raw (continuous) data of the land recorders (in proprietary cube and MSEED formats) and the shot records (airgun sources) in SEGY-format (standard exchange format).

2017年7月至8月，作为INGON项目的组成部分，科研人员在斯里兰卡南部近海开展了近海地震测量工作。本项目此部分的主要目标为研究斯里兰卡南部陆洋过渡带（continent-ocean transition）的深部结构，以及印度与斯里兰卡的早期板块漂移（plate drift）过程。本次海洋测线通过在斯里兰卡境内布设15个陆上地震台站实现了延伸，本次数据发布收录了其中气枪震源的陆上观测数据。本数据集包含陆上记录仪的原始（连续）数据（采用专有cube格式与MSEED格式存储），以及采用SEGY格式（标准交换格式）存储的震源记录（气枪震源数据）。
