SMARTIES cruise - Ocean Bottom Seismometer (OBS) data - Datasets from OBS #1 to #9

This dataset contains seismic data from 17 OBS collected in the equatorial Atlantic Ocean during the SMARTIES cruise in 2019. 12 OBSs are located along the eastern Romanche transform and fracture zone, and 5 OBSs are located along the Mid-Atlantic Ridge.

The OBS data are vertical components and recorded in MiniSEED format. The data collection started from 2019-07-20T00:00:00 to 2019-08-16T24:00:00.

This dateset includes raw data from OBS #1 to OBS#9. OBS#8 was lost.

Data from OBS#10 to OBS#19 are available from a companion dataset. OBS#15 recorded no data.
