An environmental survey of the coastal zone was carried out in the eastern section of the Far Eastern Marine Biosphere Reserve on September 5–6 2020, immediately after Typhoon Maysak passed over the south of Primorsky Krai on September 3–4 2020. The survey aimed to study the possible impact of suspended matter flowing down from the road construction in the Land of the Leopard National Park on coastal marine ecosystems of the reserve. Suspended matter was found to have no noticeable effect on water transparency, its salinity, dissolved oxygen content, concentration of chlorophyll-A and plankton community in the surveyed bays. A turbid spot with a slight decrease in the oxygen content was found outside the bay entrance at a depth of more than 15–20 m. Its formation was apparently caused by intensified hydrodynamic processes during Typhoon Maysak.
