Analysis of long-term data (from 2002 to 2020) obtained from the MODIS spectroradiometer showed that a seasonal increase of chlorophyll a concentration near the southeastern coast of Kamchatka Peninsula in September – October is typical for this area. However, the development of phytoplankton in this water area in late September – early October 2020 was very active, the pigment content was several times higher than the long-term average, including in the Avacha and Kronotsky bays. High concentrations of the substance were marked not only in coastal areas with intense river runoff, but also in areas of the shelf and continental slope at a distance of up to 100 km. The probable cause of this phenomenon was the influx of nutrients from deeper layers as a result of wind-wave mixing caused by the passage of three deep cyclones over the study area in the period from September 19 to October 7, 2020. When assessing thermal conditions, it was found that in the autumn period of 2020, significant positive water temperature anomalies were observed off the coast of Kamchatka. However, high concentrations of chlorophyll a in this area have been observed repeatedly, for example, in October 2018 and 2019 under normal temperature conditions. Thus, in autumn, the correlation between water temperature variations and pigment content in the Avacha and Kronotsky bays is weakly expressed. In the time function of the first decomposition mode according to EOF, two seasonal peaks of active photosynthetic activity were determined: in May and October. Since 2016, autumn phytoplankton breeding has been more abundant than spring. In the spatial distribution of the first mode, coastal areas and a vast zone along the edge of the shelf in the area of Avacha Bay are highlighted, while the second mode shows the estuarine areas of the Kamchatka Bay.
