| Abstract: |
| One of the most reliable and accurate methods for monitoring the marine environment is the ocean submerged buoy. Submerged buoys work underwater and their observations complement those of sea-surface buoys to achieve stereoscopic observation of the marine environment. To make forecasts for the dynamic deep-sea environment and safeguard the marine military environment, real-time data is required. As such, the development of a quasi-real-time fixed-point continuous observation system is both urgent and necessary. In this study, we designed a domestic deep-sea quasi-real-time-transmission submerged buoy system. We focused on performing a hydrodynamic analysis of the anchoring system, synchronizing the observation equipment and optimizing the overall design technologies used to ensure the safety, reliability, and low power consumption of the quasi-real-time communication systems. We investigated real-time transfer technologies such as the manufacture of light inductively coupled transmission cables, deep-sea inductive coupling transmission, and intelligent receiving and transmitting communications. In addition, we studied their applications in deep-sea areas to test their stability and reliability, and developed two types of real-time submerged buoys. The quasi-real-time-communication submerged buoy system integrates 1 anti-pollution conductivity-temperature-depth (CTD) sensor, 19 inductively coupled CTDs, 8 inductively coupled water temperature (T) sensors, 4 inductively coupled transmission acoustic Doppler current profilers (ADCP), 2 single-point ocean current meters, 6 inductively coupled data transmission instruments, and 2 sets of acoustic release transponders. The body of the submerged buoy system contains three underwater streamlined buoys, one set of communication floats, a quasi-real-time satellite communication device (semi-submersible underwater winch or sea surface float), and a mooring system. The deep-sea quasi-real-time-communication submerged buoy system obtains high-frequency, multi-element, multi-level, long-term, continuous observation data such as temperature and salt depth and ocean current data at a depth of 2 000 m, which is transferred to a shore-based lab in quasi-real-time for solving scientific problems and providing timely data to ensure safety in the marine environment. |
