With 70% of the Earth covered in water, there is a significant gap in the seismic data catalogue which offshore datasets could refine and compliment current surface research. Güralp Systems have understood this and have been developing broadband Ocean Bottom Seismometers (OBS) systems for over 25 years.

Güralp have deployed systems in a range of ocean environments, from the Japan Trench to the North Sea, including passive and active seismic surveys, ambient noise recording, real-time reservoir monitoring and ocean bottom observatories. These applications can be achieved with Güralp’s cabled and autonomous OBS family.

We have taken our knowledge and success, and invested into developing the next generation of autonomous OBS, the Aquarius family. The Aquarius family allows researchers to download raw seismic data via acoustic communications with zero cables to shore or other infrastructure during any period of the deployment. This capability allows the scientist to visit the deployment location multiple times to download data from events of interest and continue with their research whilst the system is still deployed at depth without disturbing the unit providing unparalleled flexibility.

The seismic community are highly motivated to perform transportable array style projects on land. Now Güralp can support the community with Aquarius; easily accessible, portable, off the shelf systems for similar array ocean based seismological research ventures.

The Aquarius family bridges the gap between real-time and offline ocean bottom systems and continues the trend of Güralp supporting the research community and supplying innovative OBS designs to meet operational requirements.
