Seismic processed data (Ocean Bottom Seismometer working area dataset, profile P200w) during RRS JAMES COOK cruise JC228, Guatemala Basin, North Pacific Ocean@en

The data set comprise processed active-source seismic data collected with ocean bottom seismometer (OBS). The seismic shots were recorded in the Guatemala Basin studying the structure of oceanic crust. Data were obtained during the expedition JC228 of the research vessel RRS JAMES COOK in December 2022. The data set consists of 35 OBS stations deployed at an interval of approx. 7 km receiving shots of a tuned 5000 cubi-inch airgun array, fired at 90 s interval. The seismic line is a 220 km long West-East trending transect running in flowline dircetion of seafloor spreading. Each OBS consists of 4 channels (channel 1: hydrophone; channel 2: horizontal component 1; channel 3: horizontal component 2; channel 4: vertical component).
