"An Ocean Bottom Seismometer (OBS) that uses acoustic telemetry to deliver near real-time seismic data from the ocean floor to the surface without cables. The Aquarius is a freefall OBS equipped with acoustic data telemetry and a digital feedback tri-axial broadband seismometer. A three-axis magnetometer and a MEMS accelerometer record the seismometer's 3D position on the seabed for data rotation during post-processing. The instrument is fitted with an absolute pressure gauge (APG) and a hydrophone. The standard hydrophone has a frequency response of 2 Hz - 30 kHz, with the option to upgrade to an ultra-low frequency version of 100 s to 8 kHz. There is also the option for an additional high performance APG. operational at +/-90 °, with a flat response between 120s and 100Hz. The long period frequency corner of this design is user-selectable from 120 sec to 1 sec allowing the sensor response to be tailored to the environment."@en .
