NANOMETRICS SMART CABLE CAPABILITIES
Scientific Monitoring and Reliable Telecommunication (SMART) cables represent an emerging space that addresses the data connectivity needs of the world in conjunction with the largely uninstrumented swath of water bodies on the planet. Nanometrics collaborated with Alcatel Submarine Network (ASN) to engineer an integrated seismic instrumentation sub-system to fit within the confines of their SMART Cable Climate Change Node (CC-node). The integrated technology includes Nanometrics Trillium Compact OBS Module, Titan Accelerometer, and Pegasus Digitizer that have been customized for ASN requirements. The first commercially available SMART cable solutions will be deployed by ASN beginning in 2026. This technology will play a critical role in monitoring seismic activity and other environmental conditions, contributing to disaster preparedness and scientific research.
Nanometrics offers compact seismic instrumentation packages customized for your SMART Cable project.

ABALONES
OCEAN BOTTOM SYSTEM FOR AUTONOMOUS DEPLOYMENTS DOWN TO 6,000 m FOR UP TO 20 MONTHS
The Abalones provides an ideal platform for autonomous OBS experiments that provides research institutes worldwide with unparalleled seismic technologies and geophysical studies on the seafloor. It has a very stable, trawl resistant sled design and a robust, conformal syntactic foam-based flotation frame that was developed in collaboration with Scripps Institute of Oceanography. The Abalones system 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.

CABLED OBS OBSERVATORY
INTEGRATED SYSTEM FOR PERMANENT, OBSERVATORY CLASS SEISMIC AND MULTIDISCIPLINARY DEPLOYMENTS
The Cabled Ocean Bottom Seismic Observatory (COBSO), is the most compact yet highly customizable subsea station. A part of the Atlantis portfolio, the COBSO provides the reliability, flexibility, and high-fidelity, real-time data required for groundbreaking multidisciplinary research projects and low-latency early warning systems. By combining the best-in-class Trillium broadband seismometer, Titan ‘Class A’ strong motion accelerometer, along with the Centaur data logger, it provides the highest-quality ocean bottom seismic data acquisition and management. Housed in a purpose-built titanium pressure vessel proven for deployments up to 6,000 meters.

OCEAN BOTTOM SEISMOMETERS
Nanometrics’ extensive portfolio of reliable, high-performing Seismometers have earned a reputation for high quality data and dependability. Choose from three OBS seismometers to fit the needs of your ocean-bottom deployment - in its own instrumentation pressure vessel, in a system pressure vessel from Nanometrics, or your own pressure vessel.

The Trillium Compact Ocean Bottom Seismometer (OBS) is an ultra-low power broadband seismometer for ocean bottom deployments to 6000m depth.

The Trillium 120 OBS delivers observatory grade performance with the ease-of-use and durability of our industry-leading, land-based Trillium seismometers.

The Trillium 360 OBS delivers broadband performance with the ease-of-use and durability of our industry-leading land-based Trillium seismometers.
OCEAN BOTTOM ACCELEROMETERS
Nanometrics Titan Accelerometers have been pre-integrated into our Atlantis Cabled Observatory and Smart Cable solutions, and can be adapted for deployments in customer or Nanometrics supplied pressure vessels. The Titan features industry leading dynamic range that, when combined with ultra-low self-noise performance, mitigates environmental noise resulting in accurate measurements and high quality data.
DATA LOGGERS
Discover the advanced capabilities of Nanometrics Data Loggers, engineered to withstand the harsh underwater environment, providing precise and reliable data collection for a variety of marine research applications. Nanometrics ensures that your ocean science is supported by accurate and comprehensive data.

Every aspect of the Pegasus OBS ecosystem has been optimized to provide the greatest efficiency for autonomous ocean bottom experiments.

Centaur Gen5 is an all-in-one digitizer, recorder, and telemetry instrument with advanced on-board data processing capable of data manipulation and detecting events in the field.
