We conducted a study of the inertial oscillations of the speed of currents in Peter the Great Bay, induced by typhoon Lionrock. The study is based on the measurements of the moored acoustic Doppler current profiler. Data analysis showed that under the action of the typhoon a field of currents with inertial oscillations (IO) of anomalous characteristics was formed in the bay. It is found that the spectral energy of the IO of currents with left and right rotation are of the same order while the major axis of the hodograph of the speed of these currents exceeds its small axis by an order of magnitude. A change of the inertial frequencies of the currents with cyclonic rotation, as well as the “red shift” of this frequency in the bottom and the “blue shift” in the surface layer of the inertial currents with anticyclonic rotation were found. Parametric IO interaction with anticyclonic rotation and the synoptic component of the currents with the same direction of rotation was detected. It has been suggested that the anomalous characteristics of inertial currents with two types of rotation are due to their interaction with the low-frequency component of the stream of Primorsky Current induced by the typhoon.

Two territories on the western coast of Peter the Great Bay were mapped in the large scale. The geobotanical mapping means revealing and displaying the essential regularities of vegetation cover. Both the spatial and temporal regularities of vegetation under natural and anthropogenic influences are well pronounced in the territory under consideration. The concept of the vegetation spatial unit (vegetation complexes) was applied as a basis for mapping. The maps and their legend were worked out as a system of vegetation combination types (vegetation combination is a spatial unit of the supracoenotic level). Such categories, as vegetation of tops and slopes, lowlands and river valleys, sea coasts reflect maximal contrasts in vegetation cover, so they are the highest level divisions of the map legend. Types of succession series and stages of series are developed for construction of the second and third levels of the legend. Communities, similar in ecotope, total species composition, saplings and some other characteristics, are referred to one type of series. 5 types of series have been distinguished: dry, fresh, moist, very moist, wet. The main factor of dynamics in considered territory is fire and the series are mainly pyrogeneous. Series are presented as sequences of vegetation stages. The vegetation stages for tops and slopes are: closed low forest — open low woodland — shrub thicket with saplings — meadow with saplings, for lowlands and river valleys they are: open low woodland — thicket of saplings — meadow or mire with saplings.

Dynamics of the sea ice cover in Peter the Great Bay is considered, for the first time for its whole area, on the base of satellite images received in 2004-2011 from the spectroradiometers MODIS mounted on the satellites Terra and Aqua. High spatial resolution maps of the ice drift are constructed for various wind conditions. Mean values of the drift velocity and wind coefficient are calculated for four parts of the Bay. In usual conditions of winter monsoon, the ice in the central part of Peter the Great Bay drifts southward with the velocity 0.5-0.6 m/s with deviation from the wind direction about 40° to the right; the ice at the western coast drifts along the island chain with the velocity 0.1-0.4 m/s under wind of any direction in the quadrant from northwest to northeast.
