Scheme, Software and Data of an Open Source Datalogger for Marine Seismology and Acoustics

Here some file from an open source datalogger created for marine seismology and Acoustic named GEOCARD.
These files are some design files for the hardware (KiCAD), sources code programming the microcontroller (software from STMCubeIDE), and some data from an Ocean Bottom Seismometer (OBS) tested near the island of Martinique in the Caribbean Sea at a depth of 1,200 meters.
