Description

Technical Field

[0001] The utility model relates to the technical field of turbulence observation devices, in particular to an integrated turbulence observation device. Background Art

[0002] With the advancement of technology, the use of unmanned vessels for ocean observation and surveys has become a new trend in marine surveys due to their low cost, high flexibility, and ability to achieve twice the result with half the effort. Semi-submersible unmanned vessels combine the functional features of unmanned vessels and submersibles and are currently primarily used in offshore hydrographic surveying and topographic mapping. Unlike surface unmanned vessels, these vessels operate with their main hull submerged, with only a portion of the hull's appendages above the surface. This significantly reduces surface wind and wave interference, significantly improving safety and stability.

[0003] Turbulence, a type of irregular, small-scale motion in fluids, has been called "the last major unsolved problem in classical physics" (Feynman, 1963). It defies precise physical and mathematical explanations, representing an unresolved bottleneck in physical oceanography and the entire theory of fluid dynamics. This situation stems from a lack of sufficient observational data to clearly discern the patterns of small-scale turbulent mixing under varying conditions. For example, numerical simulations have shown that when the model resolution is sufficiently high to resolve submesoscale events, the sea surface turbulent heat flux exhibits systematic changes, with its intensity approaching its average value (Suetal, 2008). This suggests that multiscale ocean processes, including those at the submesoscale, influence turbulence, but these results remain unconfirmed by observation. Therefore, breaking through the constraints of conventional thinking and adopting innovative technical solutions to acquire sufficient first-hand turbulence data is crucial for achieving breakthroughs in turbulence theory and a focal point of international competition in oceanography and fluid dynamics.

[0004] In addition to influencing large-scale circulation, water masses, and carbon dioxide distribution by affecting the vertical redistribution of ocean heat, turbulence also has significant climatological effects. In current oceanographic and atmospheric science research, small-scale ocean turbulence processes, on the scale of 0.1 to 1 m, are a hotspot, primarily influencing climate change by affecting heat fluxes at the air-sea interface. For example, changing the turbulent mixing coefficient within the ocean interior in ocean models can dramatically alter the structure of deep-ocean circulation (e.g., Simmons et al., 2003). Changing the intensity of turbulent mixing in the ocean barrier layer or thermocline in ocean-climate models can significantly alter the intensity of the El Niño Southern Oscillation (ENSO), potentially suppressing or even eliminating ENSO (e.g., Maes et al., 2005; Meehl et al., 2011). Therefore, turbulent mixing is considered an important theoretical approach for improving ENSO forecasts in the future (Wenge et al., 2021).

[0005] Given the scientific significance of turbulence and its close connection to climate and human ocean activities, clarifying the impact of turbulence has become a major national need. Currently, there is a lack of in-depth understanding of the mechanisms governing turbulent mixing, including its temporal and spatial distribution variability and its interrelationships with multiscale ocean and atmospheric processes. This inability to accurately establish the relationship between turbulence and other processes further restricts our understanding of the resulting redistribution of ocean heat, salinity, and carbon dioxide concentration. This impedes the accurate parameterization of subgrid processes in traditional ocean and ocean-atmosphere dynamic models, hindering the accurate construction of ocean and ocean-atmosphere numerical models. This leads to biased forecasts of high-impact events such as typhoons and ENSO, and also hampers our understanding of the ocean's absorption and storage of carbon dioxide. Furthermore, turbulent mixing can affect depths of up to hundreds of meters, significantly altering the vertical density structure of the water column, thereby affecting the direction and intensity of underwater sound propagation and significantly impacting the operational stability, maneuverability, and communication security of underwater platforms. Insufficient understanding of the "turbulence" process and mechanism has led to the inability to accurately predict the changes in ocean background and underwater acoustic propagation fields, limiting the maneuverability and safety of underwater mobile platforms, and has therefore become a technical problem that urgently needs to be solved.

[0006] Due to the limitations of instruments and equipment, it is impossible to achieve simultaneous observation of turbulence and temperature, salinity, depth / current, which hinders the study of the mechanism of turbulence generation and variation. This is one of the reasons why there has been no breakthrough in ocean turbulence theory for a long time. Summary of the Invention

[0007] In view of the above-mentioned deficiencies in the prior art, an integrated turbulence observation device is provided to achieve synchronous observation of turbulence and temperature, salinity, depth / flow.
