1. Product Advantages

• Deep-Sea Tsunami Monitoring: Pressure detectors deployed on the seabed continuously acquire pressure data and invert sea level variations to effectively identify tsunami long-wave signals in open and deep ocean environments.

• Underwater Acoustic Data Transmission: Both the seabed base station and surface main buoy are equipped with acoustic communicators to transmit and receive underwater data reliably.

• Optional Multi-Satellite Communication Modes: Fitted with satellite communication modules supporting satellite or low-orbit satellite communication for remote data transmission in far oceans.

• Anomaly Identification & Alert Reporting: Identifies anomaly events based on pressure and water level variations; automatically switches to intensive data reporting mode when preset thresholds are exceeded.

• Recoverable Subsea Equipment: Seabed base station features releasers and floats that separate the subsea device from the anchoring structure during recovery, allowing it to float to the surface.

• Modular Expansion Capability: Supports integration of various marine environmental sensor modules for multi-scenario applications.
