Seismic processed data (Ocean Bottom Seismometer working area dataset, profile P400) during RRS JAMES COOK cruise JC228, Guatemala Basin, North Pacific Ocean

The data comprise processed active-source seismic data acquired with ocean bottom seismometer (OBS) along profle P400. The data were collected in the Guatemala Basin of the Eastern Pacific Ocean during the joint German/United Kingdom expedition JC228 of the research vessel RRS JAMES COOK in December of 2022. The data set consists of 11 OBS stations deployed at an interval of 7.5 km receiving shots of a tuned 5000 cubi-inch airgun array, fired at an interval of 75 m, along a 90 km long profile. Each OBS consists of 4 channels (channel 1: hydrophone; channel 2: horizontal component 1; channel 3: horizontal component 2; channel 4: vertical component).

本数据集包含沿剖面P400采集、经处理的主动源地震数据，采集设备为海底地震仪（Ocean Bottom Seismometer，OBS）。该数据于2022年12月由德英联合科考航次JC228搭载科考船RRS JAMES COOK，在东太平洋危地马拉海盆完成采集。数据集沿90公里长的剖面布设了11台海底地震仪站点，站点布设间距为7.5公里；系统接收经调校的5000立方英寸气枪阵列所激发的震源信号，气枪激发间距为75米。每台海底地震仪均配备4道采集通道：第1通道为水听器（hydrophone）；第2通道为水平分量1；第3通道为水平分量2；第4通道为垂直分量。
