Ocean bottom hydrophone sgy-files of wide-angle seismic data across the Xisha Trough profile OBH_IV, South China Sea@en

Wide-angle seismic data acquired across the Xisha Trough in the South China Sea. The data were acquired with 10 Ocean Bottom Hydrpobones from GEOMAR in 1996. The records are reduced to 6 km/s, relocated, and filtered using a bandpass filter, and wiener predictive error filter. Navigation is included as an ASCII file with longitude and latitude of shots.本数据集为采集自南海西沙海槽的广角地震数据。1996年，科研团队采用来自GEOMAR的10台海底水听器（Ocean Bottom Hydrophones）完成了本次数据采集。所获取的地震记录已完成6 km/s参考速度折算、观测系统重新定位，并分别通过带通滤波器（bandpass filter）与维纳预测误差滤波器（Wiener predictive error filter）完成滤波处理。数据集附带ASCII格式导航文件，内含各炮点的经纬度信息。
