Abstract

The paper studies the synoptic variability of the light beam attenuation coefficient and intensity of chlorophyll a fluorescence on the sea surface and its relationship with the distributions of hydrological parameters based on the hydrological and bio-optical measurements carried out off the coast of Crimea during the 127th cruise of R/V Professor Vodyanitsky in summer 2023. The measurements were carried out on a finer station grid with the vessel moving from west to east twice with a weekly interval (14–20 June and 22–28 June). It is shown that due to Rim Current penetration into the polygon during the 2nd stage of measurements, the Azov-Kerch waters flew into the polygon water area more intensely. This was accompanied by a decrease in waters transparency and salinity, and an increase in temperature, which was also influenced by the ongoing seasonal heating. In most of the study area, data from both measurement stages revealed a significant tendency of increasing chlorophyll a fluorescence intensity in water areas with a higher beam attenuation coefficient. Changes of the vertical thermohaline and biooptical waters structure on a scale of about a week were observed in the entire measurement layer and were manifested in changes in the number and values of the maxima of the chlorophyll a fluorescence intensity, the light beam attenuation coefficient, temperature and salinity vertical gradients, as well as their depths. The main maximum of the light beam attenuation coefficient was observed either in the surface layer or in the layer of seasonal thermocline and halocline, while the maximum of the chlorophyll a fluorescence intensity was located under the layer of seasonal thermocline and halocline. The study found a significant linear correlation between the distributions of the depth of the seasonal thermocline and the depths of the maximum of the light beam attenuation coefficient and chlorophyll a fluorescence intensity, as well as between the depths of the seasonal halocline and the maximum intensity of chlorophyll a fluorescence
