Purpose. The work is aimed at assessing the temporal and spatial scales of variations in the physical and biological parameters of the seawater surface layer in the immediate vicinity of the urban rainwater drainage outlets in the Sevastopol Bay. Methods and Results. The study area was limited to the Sevastopol Bay. Measurements were taken at the locations of the rainwater drainage outlets, namely in the Artilleriyskaya, Apollonova and Gollandiya bays. Temperature and salinity were measured by an unmanned surface vehicle (USV) using the TMA-21 sensor. The stations were located in a straight line normal to the coast from the rainwater drainage outlet. Quantitative and size composition of total suspended matter and bacterioplankton particles were determined using the Cytomics TM FC 500 flow cytometer. Water temperature was shown to vary within 1.5 °C and its horizontal gradient was weakly pronounced. -1 In the salinity field, the gradient reached 0.5 m . The maximum concentrations of suspended matter 6 -1 were revealed in the apical part of the Artilleriyskaya Bay (about 0.5 × 10 particles mL )...
