Trillium Compact OBS

An ultra-low power broadband seismometer for ocean campaigns.

A reputation for dependability

The Trillium Compact Ocean Bottom Seismometer (OBS) is an ultra-low power broadband seismometer for ocean bottom deployments to 6000m depth. The OBS vessel and gimbal design preserves the full performance of the land-based Trillium Compact seismometer, including its exceptional dynamic range and low noise floor

Performance & Dependability

Incorporating a robust and reliable leveling gimbal that operates over a full 360° range, the Compact OBS will auto-level from all orientations. A full titanium cylindrical pressure vessel for 6000m deployments, or aluminum-anodized enamel painted vessel for 1800m deployments. Proven glass epoxy connectors ensure exceptional resistance to corrosion in marine environments.

Availability via two connections

The system employs two separate connections: the primary analogue connection as well as a digital connection. The digital connector is provided for final configuration and sensor verification prior to deploying the OBS overboard.
