Deep-Sea Ocean‑Atmosphere Coupled Buoy Project – SCSIO, South China Sea

Dexonmarine delivered an advanced deep-sea ocean‑atmosphere coupled buoy for the Chinese Academy of Sciences South China Sea Institute of Oceanology (SCSIO). Deployed in the equatorial Indian Ocean, the buoy enables reliable environmental monitoring in ultra-deep waters, integrating Beidou and Iridium dual-link communication for stable real-time data transmission.

• Dual Communication Links: Beidou + Iridium for uninterrupted data transfer.
• High-Frequency Sampling: 1 Hz sensor measurements, aggregated every 30 minutes.
• Comprehensive Monitoring: Surface atmospheric conditions, four-component radiation flux, sea surface skin temperature, and 0–80 m water column profiles.
• Wave Observation: Measures height, period, and direction.
• Remote Programmable: Supports human‑machine interaction for configuration and monitoring.

• Deep-Sea Deployment: Launched from the SCSIO “Experiment 3” research vessel.
• Autonomous Operation: Self-contained buoy with low-power, patented sensor and data acquisition system.
• Real-Time Monitoring: Ensures reliable environmental data transmission to shore stations.

• Provides critical high-quality data for ocean‑atmosphere interaction studies.
• Supports deep-sea dynamics, climate process research, and environmental monitoring networks.
• Enhances scientific infrastructure for extreme offshore conditions.
• Demonstrates Dexonmarine’s expertise in precision marine instrumentation for ultra-deep waters.
