INNOVATIVE SLED FOR THE CHALLENGES OF FREE-FALL DEPLOYMENTS

Part of the Atlantis portfolio of OBS solutions, the Abalones autonomous ocean bottom system combines Nanometrics’ industry leading Pegasus OBS digital recorder and Trillium OBS seismometer technologies with Scripps Institution of Oceanography’s versatile OBS deployment technology to provide a turnkey solution for deployments in shallow, intermediate, and deep water up to 6,000 m. The versatile frame and four-channel Pegasus digital recorder are compatible with a range of three-channel seismic sensor options including broadband seismometers, short-period geophones, strong-motion sensors, as well as recording a single channel sensor such as a differential pressure gauge (DPG) or hydrophone.

QUALITY DATA FOR OBS CAMPAIGNS

The Ablones offers a very stable, trawl resistant design and a robust, conformal syntactic foam-based flotation frame. The Abalones releases the seismometer directly onto the seafloor to achieve optimal seismic coupling to the earth and mechanical decoupling from the frame, but still surrounds the seismometer, shielding it from ocean currents to minimize unwanted environmental noise.

STREAMLINE LOGISTICS

Designed specifically for ocean bottom experiments, the Pegasus OBS data acquisition workflow optimizes onshore and shipboard processes to address common challenges of this demanding environment. Powerful planning tools enable pre-configuration of the digital recorder and sensors prior to boarding the ship.

BENEFITS

Robust design Stable and trawl resistant, conformal syntactic foam-based flotation frame.  
Coupling to the earth

Releases the seismometer directly onto the seafloor for optimal seismic coupling.

  
Seismometer shielding

Shielded from ocean currents to minimize unwanted environmental noise.
