Vertical profiles of temperature, salinity, fluorescence, and irradiance were obtained using the CTD and profiling radiometer.
A profiling Reflectance Radiometer (PRR) system (Biospherical Instruments, USA) was used for optical sampling, which consists of an underwater profiler PRR-800 and a surface reference radiometer PRR-810. The sampling frequency of the PRR is 5 Hz, and the lower limit of irradiance detection reaches 10−5 μW/(cm2·nm). The PRR measures 18 bands from 305–875 nm, and the bandwidth is 10 nm. A compact CTD (Alec Electronics, Japan) was deployed together with PRR-800 and is equipped with temperature, salinity, pressure and fluorescence sensors.169.98333333333332-164.1166666666666773.9833333333333380.76666666666667National Key Research and Development Program of Chinahttps://doi.org/10.13039/5011000121662021YFC2801103National Natural Science Foundation of Chinahttps://doi.org/10.13039/50110000180942276239
