The broadband Ocean Bottom Seismograph is a marine instrument that collects natural earthquakesartificial sound sources.OBS project has been leading by TORI, Academic Sinica,National Sun Yat-sen University from designing, testing to success. OBSs have been deployedrecovered in several research cruisesobtained the great results.

Application of a high reduction mechanism to design leveling device, with full 360 degrees restoring leveling device,0.1 degree accuracy, will auto-leveling from all possible orientations.

The technology can be used in academic research to increases the observation area on the sea,also used in marine resource exploration. The application targets research institutesthe marine energy industry.
