Nanometrics - Model Abalones -Autonomous Ocean Bottom System
For streamlined autonomous OBS deployments requiring high-quality seismic and sensor data. 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.
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.
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.
KOPRI`S RESEARCH PROGRAM
