三亚附近海域海洋温盐深信息分析数据

通过抛弃式温盐深探头实时采集海洋中的温度、盐度、深度、密度、声速数据实现对海洋环境实时监测。通过对比同一经纬度下不同时间测试数据的差异，分析海洋环境变化情况。将分析的结果应用到实际场景中，为研究海洋物理学、声纳等海域探测设备、船舰等海洋运输作战工具提供数据支撑。利用抛弃式温盐深探头水下部分实时获取随深度变化的温度、电导率数据，以DPSK方式进行信号调制，通过漆泡线传递数据至数据采集模块。对采集到的原始数据以DPSK方式进行信号解调，获取实时深度、温度、电导率数据，进行数据公式推导计算盐度：
S=0.008-0.1692*Rt^0.5+25.3851*Rt+14.0941*Rt^1.5-7.0261*Rt^2+2.7081*Rt^2.5+(T-15)/(1+0.0162*(T-15))*0.0005-0.0056*Rt^0.5-0.0066*Rt-0.0375*Rt^1.5+0.0636*Rt^2-0.0144*Rt^2.5;
计算声速：
V=1449.2+4.6*T-0.055*T^2+0.00029*T^3+(1.34-0.01*T)*(S-35)+1.6*0.01*D
计算密度：
ρ=ds0/(1-(P*10/Kstp));
其中,T:温度,S:盐度,P:压力,D:深度，V:声速，ρ：密度，Rt:电导率比值。

Real-time marine environmental monitoring is realized by collecting temperature, salinity, depth, density and sound speed data in the ocean via expendable conductivity-temperature-depth (XCTD) probes. By comparing differences between test data at the same longitude and latitude across different time points, changes in the marine environment are analyzed. The analyzed results are applied to practical scenarios, providing data support for marine physics research, marine detection equipment such as sonar, and marine transportation and combat tools such as vessels.

The underwater part of the XCTD probe acquires real-time temperature and conductivity data varying with depth. The signals are modulated using DPSK (Differential Phase Shift Keying) and transmitted to the data acquisition module via enameled copper wire. The collected raw data are demodulated via DPSK to obtain real-time depth, temperature and conductivity data. Salinity is calculated via the following formula:
$$S = 0.008 - 0.1692 imes R_t^{0.5} + 25.3851 imes R_t + 14.0941 imes R_t^{1.5} - 7.0261 imes R_t^2 + 2.7081 imes R_t^{2.5} + frac{T-15}{1 + 0.0162 imes(T-15)} imes 0.0005 - 0.0056 imes R_t^{0.5} - 0.0066 imes R_t - 0.0375 imes R_t^{1.5} + 0.0636 imes R_t^2 - 0.0144 imes R_t^{2.5}$$

Sound speed is calculated via:
$$V = 1449.2 + 4.6 imes T - 0.055 imes T^2 + 0.00029 imes T^3 + (1.34 - 0.01 imes T) imes(S-35) + 0.016 imes D$$

Density is calculated via:
$$
ho = frac{ds_0}{1 - frac{P imes10}{K_{stp}}}$$

Where: T = temperature, S = salinity, P = pressure, D = depth, V = sound speed, ρ = density, and $R_t$ = conductivity ratio.
