RBRquartz³ APT | Bottom Pressure Recorder with Accelerometer
Bottom pressure recorder with accelerometer

RBRquartz³ APT:
Accelerometer, Pressure, Temperature

The RBRquartz³ APT combines a triaxial quartz accelerometer with the capabilities of the RBR bottom pressure recorders. The alliance of a 16Hz strong- and weak-motion seismometer, and the pressure measurement with 10ppb resolution make this instrument ideal for deepsea early earthquake warning and tsunami monitoring.

  • Long deployments
  • High accuracy
  • Quartz stability
  • Up to 16Hz sampling
  • Ethernet connectivity
  • 10ppb resolution

RBRquartz³ APT

The RBRquartz³ APT  is ideal for ocean bottom earthquake and tsunami early-warning systems, providing continuous measurements while connected to a cabled realtime network. The instrument is designed for rapid ROV deployment, and penetrates the seabed to ensure good seismic coupling and insulation from potential noise sources. The RBRquartz³ APT supports both autonomous installations and realtime data streaming to cabled observatories.

The sub-second integration time consumes less power during sampling, significantly extending the time until the next battery replacement. User selectable integration time for each reading means you can adjust the resolution to your measurement needs. Datasets can be read directly in Matlab, or exported to Excel, OceanDataView®, or text files.
