High performance broadband ocean bottom seismometers

Introducing Aquarius, a compact, free-fall OBS that offers the option of near real-time alert notifications for tsunami or earthquake early warning.

We are pleased to introduce a new form of free-fall, stand-alone OBS that utilises acoustic telemetry to aid installation and data retrieval to depths of up to 6000 m. There is also an enhanced version, Aquarius+, that can deliver triggered event alerts to the surface in near real-time, and is controllable from the surface to retrieve more detailed data selected by time frame or by event. For more information see our Aquarius datasheet here.

 

Or, choose from our wide range of OBS housings, enhanced and developed over thirty years, with options for virtually every deployment scenario.

We have designed OBS housings to perform at different depths via the most appropriate deployment method. Each can be combined with the sensor or sensors that you need to give you the data you require.

All of our OBS systems are fitted with a magnetometer to determine instrument orientation at depth to maximise data quality and your investment. To find out more about our OBS range take a look at our Güralp OBS brochure View as PDF.

Key Features

  • Choose from:
    • Full autonomous operation with or without acoustic communication/alert capability
    • Real time cabled systems for incorporation into monitoring networks
  • Deployable by ROV, free-fall or on a winch
  • All OBS systems are fitted with a magnetometer to determine instrument orientation at depth
  • Option to incorporate differential pressure gauges (DPGs) or absolute pressure gauges (APGs) for applications such as tsunami early warning systems
