“…The coldest month is December, with an average monthly air temperature at the head of Penzhina Bay of about minus 23 • C. The absolute minimum temperature the air reaches here is minus 52.6 • C. The warmest month of the year is July, when the average monthly air temperature reaches 14 • C, while the air warms up to 19 • C on average in the daytime. Permafrost is widespread in the region, and its thickness reaches tens of meters near the coast of Penzhina Bay (references to primary sources are in [39]).…”

“…Its catchment area is 24,100 km 2 ; its average annual discharge is 230 m 3 /s. At its flooding peak, this is usually 2074 m 3 /s; its minimum discharge in the summer-fall period is 141 m 3 /s (references to primary sources are in [39]). The relatively large Penzhina River flows into Penzhina Bay at its north-east end; this is the second largest river to enter the Sea of Okhotsk after the Amur River [38].…”

“…It is located at a subpolar latitude. Despite a significantly lower salinity in summer, daily tidal variations cause strong mixing and a vertical homogeneity of the temperature and salinity of the water at the head of Penzhina Bay [39,40]. This basin is ideal for studying the natural variations of carbonate system parameters and understanding how they act as controlling factors in a hypertidal estuary.…”

Understanding the factors that control carbonate systems is an important goal due to the complex interactions between the hydrophysical and chemical–biological conditions in coastal basins. The results of this paper present the state of the carbonate system in Penzhina Bay and its adjacent waters—the Shelikhov Gulf—in July 2023, during spring tides with 13 m height. The area we studied included the length of the largest river in the region, the Penzhina River, from the peak of its summer flood to its boundary with the Shelikhov Gulf (the Sea of Okhotsk). This unique dynamic basin, with a length of about 800 km, was studied over 17 days. During this period, the entire water column of Penzhina Bay, down to a depth of about 60 m, and the surface water layer of the Shelikhov Gulf were undersaturated in terms of CO2, with low levels relative to those of the atmosphere. To explain this observation, the dissolved oxygen, nutrients in mineral and organic forms, humic substances, chlorophyll a, and photic zone thickness are presented for the entire basin under study, together with its hydrological data. The results of daily observations of the carbonate system at fixed anchorage stations characterize two contrasting regions of Penzhina Bay: one that was more exposed to continental runoff, which had salinity levels in the range of 8.0–21.3 psu during one tidal cycle; the second had smaller variations in salinity in the range of 31.6–32.9 psu during one tidal cycle. This study emphasizes the importance of biological processes and continental runoff on the variability of the carbonate system parameters and CO2 fluxes at a water/atmosphere boundary with extreme tidal conditions in this ecosystem that is barely affected by human activities.

The paper dwells upon the problem of multi-criteria choice of ways to develop generating capacities to supply power to remote consumers. We herein propose a two-step multi-criteria analysis method: choosing promising power-generation technology first, and then specifying the generating-capacity structure. The paper describes the structure of the proposed multi-criteria methods: the interval TOPSIS method for Step 1; for Step 2, an upgraded analytic hierarchy process based on identifying the structure of the decision maker’s preferences. We demonstrate the use of this method with evidence from the Penzhinsky District, Kamchatka Krai. Thermal power plants, hydroelectric power plants, diesel power plants, as well as solar and wind power are analyzed as power sources. Step 1 includes: analyzing the potential power-supply loads in a specific area; formulating alternative power-generation technology; formulating goals and criteria; criterion-based evaluation of alternative options using objective and subjective models; multi-criteria evaluation of alternatives; analyzing the sensitivity of results and the selection of promising technology. Step 2 includes: formulating goals and criteria on the basis of the selected power-generation technologies; formulating the available alternatives; criterion-based evaluation of alternatives; multi-criteria evaluation and final decision-making.
