圣罗莎岛附近海域温盐深信息分析数据

通过抛弃式温盐深探头实时采集圣罗莎岛附近海域中的温度、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 implemented by collecting temperature, salinity, depth, density, and sound speed data in the sea area adjacent to Santa Rosa Island using expendable conductivity-temperature-depth (XCTD) probes. Marine environmental variations are analyzed by comparing discrepancies among test data collected at identical longitude and latitude coordinates across different time points. The analyzed findings are applied to practical scenarios, offering data support for research in marine physics, marine detection apparatus such as sonar, and marine transportation and combat tools including ships and naval vessels.

The underwater section of XCTD probes is utilized to acquire real-time temperature and conductivity data that vary with water depth. Signal modulation is conducted via Differential Phase Shift Keying (DPSK), and data is transmitted to the data acquisition module through enameled wire. Subsequently, signal demodulation via DPSK is performed on the collected raw data to obtain real-time depth, temperature, and conductivity data. Salinity is calculated via formula derivation as follows:
S = 0.008 - 0.1692*R_t^0.5 + 25.3851*R_t + 14.0941*R_t^1.5 - 7.0261*R_t^2 + 2.7081*R_t^2.5 + (T-15)/(1+0.0162*(T-15))*0.0005 - 0.0056*R_t^0.5 - 0.0066*R_t - 0.0375*R_t^1.5 + 0.0636*R_t^2 - 0.0144*R_t^2.5;
Sound speed is calculated as:
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;
Density is calculated as:
ρ = ds0/(1 - (P*10/Kstp));
Where T represents temperature, S represents salinity, P represents pressure, D represents depth, V represents sound speed, ρ represents density, and R_t represents conductivity ratio.
