RBRquartz³ APT | Bottom Pressure Recorder with Accelerometer
The RBRquartz³ APT is a combined triaxial quartz accelerometer and a bottom pressure recorder. The alliance of a 16Hz strong- and weak-motion seismometer, and the pressure measurement with 10ppb resolution make this instrument ideal for deep-sea early earthquake warning and tsunami monitoring. The RBRquartz³ APT is designed for both autonomous installation or real-time cabled observatories with ethernet connectivity. Designed for rapid ROV deployment, the instruments penetrates sea bed sediments and has good seismic coupling.
