Aquarius
产品介绍
The revolutionary Aquarius is an evolution of our Liber ocean bottom seismometer, utilising acoustic telemetry capability to deliver near real-time seismic data from the ocean floor to the surface without cables.
Fully operational at +/- 90 degrees, the Aquarius OBS system is a compact, free-fall seismic underwater observatory, ideal for free-fall deployment onto the sea floor at depths of up to 6000 m. The low profile and compact design is optimised to minimise the noise generated by the current flow whilst reducing transportation and deployments costs.
The seismometer has a flat response between 120 s and 100 Hz, with a user-selectable long-period corner from 120 s to 1 s, so you can tailor the response to the environment. Additional sensors including an APG and a Hydrophone are also incorporated into the system.
The acoustic telemetry is used, following deployment, to transfer state-of-health parameters and noise performance plots from the seabed, select the desired response of the sensor and to measure the time offset of the digitiser housed in the OBS pressure vessel. If desired, there are options to utilise the acoustic telemetry to transmit triggered event data to a receiver located at the surface on a buoy or rig in near-real-time for alert applications.
Once on the seabed, the Aquarius can be accurately located using integrated location and ranging software. It is also compatible with Sonardyne USBL systems.
The Aquarius recovery system is initialised either via the acoustic link, through a pre-programmed time-out, or with the optional critical level battery trigger. Once activated, a burn-wire system releases the ballast for recovery of the instrument and a satellite tracking system tracks the instrument on the sea surface.
