Ensuring successful outcomes for every deployment

From experiment design to science-ready-data, this is the industry's most advanced, integrated and autonomous Ocean Bottom Ecosystem that brings together Scripps' industry-leading technology with Trillium OBS seismometers and the revolutionary new Pegasus OBS digitizer.

The Triton OBS features a hinged sensor cover that shields the seismometer from ocean currents when it is dropped from the Triton onto the ocean floor.


The Triton Ocean Bottom System was developed with an emphasis on ensuring scientific outcomes by providing an intuitive experience that yields ready-to-use, complete data sets. This versatile system combines minimal size, weight and power requirements with advanced data transfer and a mobile user interface to provide the most efficient OBS solution possible.  


A mobile user interface removes the need to open pressure vessels on the ship which greatly improves the onboard workflow; the robust internal memory eliminates the inherent risks in using swapable media. Multiple available configurations of the primary, reserve and backup batteries provides highly reliable power to all critical subsystems. 


The integrated Triton system provides added smart-system capabilities including:


  • Manage attached seismometer with plug+play sensor API, identifies model, serial, instrument response and sensitivity
  • Configurable automatic sensor/gimbal levelling schedule
  • One-click time-sync of internal clock to GPS before/after deployment
  • Sensor, digitizer and gimbal state-of-health (SoH)
  • Sensor-digitizer instrument response metadata automatically generated
  • Companion control and harvesting apps to manage complete system

Combining expertise in ocean science and seismic instrumentation

The long-standing collaboration between Nanometrics and Scripps Institution of Oceanography has led to a joint R&D partnership that integrates Scripps’ industry-leading OBS technology with Nanometrics’ OBS seismometers and the revolutionary, new Pegasus digitizer technology. 


The Triton OBS system features a low-profile design and a robust conformal syntactic-foam flotation‑based structure. To minimize environment noise, the seismometer is mechanically decoupled from the system while still completely shielded from ocean currents. 


Designed to be deployed for shallow, intermediate, and deep water up to 6,000 m, for durations ranging from days to over two years. The Triton is also equipped with self‑contained anchor and flotation designed for quick deployment and recovery.


Ocean Bottom Seismometers

Trillium Compact OBS


Nanometrics has a long history of developing reliable, high-performing Ocean Bottom Seismometers (OBS) which have earned a reputation for rugged dependability. The Trillium Compact OBS is an ultra-low power broadband seismometer for deployments up to 6,000 m depth. 


The precise, kinematic 360° gimbal auto‑levels from any orientation ensuring successful deployment and implementation providing the full performance of a land‑based seismometer, including its exceptional dynamic range, low noise floor and low power consumption. A titanium pressure vessel and proven glass epoxy connectors ensure exceptional ruggedness and resistance to corrosion in marine and freshwater environments.

Pegasus Data Collection, Handling and Management 

The Pegasus series of digitizers are a revolution in size, weight and power consumption while maintaining the fidelity and versatility of a modern broadband data acquisition system. The class-leading low power consumption significantly reduces battery requirements and overall OBS system size and weight. With a boot time of a few seconds, smart sensor auto configuration and the ability to recover one year of data in just 1-2 minutes, Pegasus is optimized for simplicity and ease-of-use ensuring the highest possible data quality and availability from even the most demanding environments.


Pegasus, modernizing the way you collect and process your data

Data recovery is via lightning-fast USB 3.0, where one year of data can be seamlessly downloaded ready for processing in just 1-2 minutes (1 GB/10 s). Pegasus operators have the option of utilizing the Nanometrics Cloud based Deployment Manager which provides all the tools required to archive, distribute, verify, audit and process the data collected. Advanced platform tool sets allow users to take high volumes of raw data right through to research-grade catalogs benefiting from our state-of-the-art machine learning, advanced beamforming and template matching algorithms.

iOS and Android mobile applications connect to the digitizer to provide the primary field interface for the Pegasus digital recorder.​​​​​​
