Abstract:
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).

Comment:
The data are provided in SEG-Y format (reduced with 8 km/s and recording time starting at -1 s). Each uploaded file (44 files in total) consists of the airgun shots recorded with the individual Ocean-Bottom-Seismometers (OBS).
The naming convention is as follows using one file p400.obs401.1.sgy as an example:
p400: profile name of JC228 survey
obs401: OBS-station number (from 401 to 410 & 235)
1: channel number (1, 2, 3, 4)
sgy: data type
Each segy-data file has header-information set that can be used for plotting and analyses:
trace-count (tracr, byte : 1) shotpoint number (byte: 17-20)
shot X coordinate (sx, byte :73-76, coordinate: latitude x 360000)
shot Y coordinate (sy, byte: 77-80, coordinate: longitude x 360000)
OBS X coordinate (gx, byte: 81-84, coordinate: latitude x 360000)
OBS Y coordinate (gy, byte: 85-88, oordinate: longitude x 360000)
