The Polar branch of Russian Federal Research Institute of Fisheries and Oceanography (VNIRO) carries out annually comprehensive surveys in the Barents Sea. This allows obtaining relevant data on distribution and occurrence of marine mammals, in particular cetaceans – the key link in the World Ocean ecosystem. In recent years, marine mammals monitoring has become increasingly important due to climate change and temperature rise in seas and oceans, that can result in habitat displacement and even possible extinction of certain species. This article summarizes the results of the vessel surveys of cetaceans carried out by the Polar branch of VNIRO in the Barents Sea in 2010–2019, as well as provides retrospective data on baleen whales (Mysticeti) and toothed whales (Odontoceti). Based on vessel survey material and taking into account data from literature sources, the current composition of the Barents Sea cetacean fauna is presented; at the beginning of the XXI century, it may include up to 16 species of 7 families. The analysis of vessel survey data made it possible to determine the status of marine mammals of this water area and to identify the frequency of their occurrence. The article presents population abundance for most species of baleen and toothed whales and shows the most likely spots of cetacean occurrence. According to the data obtained, white-beaked dolphin Lagenorhynchus albirostris is the most abundant, frequently sighted, and a year-round species: it accounts for more than 80 % of the total number of surveyed animals and about 50 % of all sighted cetaceans. Beluga whale Delphinapterus leucas and harbor porpoise Phocoena phocoena are also classified as permanent residents of the water area, and their localization is mainly confined to the Kola Peninsula coastal zone. May to October, the Barents Sea is regularly visited by species arriving from other Atlantic Ocean areas for feeding: minke whale Balaenoptera acutorostrata, fin whale Balaenoptera physalus, and humpback whale Megaptera novaeangliae. Narwhal Monodon monoceros and northern bottlenose whale Hyperoodon ampullatus are rarely sighted in the Russian Arctic western area.

The Russian fishery for invertebrate hydrobionts in the Barents Sea includes the list of a dozen species of crustaceans, mollusks, and echinoderms. This type of fishery is characterized by great diversity in relation to the status of exploited stocks, catch size, and economic efficiency of the fishery. The list of up-to-date problems of this industry is long and includes biological, scientific, commercial, socio-economical, and market issues. Among the main problems of the Russian invertebrate fishery in the Barents Sea, overfishing, underutilization of a number of stocks, and significant emissions from fishing waste are considered. The causes of these problems, possible solutions and the priorities of such a solution are analyzed.

AbstractCanada has five unresolved maritime boundaries. This might seem like a high number, given that Canada has only three neighbours: the United States, Denmark (Greenland), and France (St. Pierre and Miquelon). This article explores why Canada has so many unresolved maritime boundaries. It does so through a comparison with Norway, which has settled all of its maritime boundaries, most notably in the Barents Sea with Russia. This comparison illuminates some of the factors that motivate or impede maritime boundary negotiations. It turns out that the status of each maritime boundary can only be explained on the basis of its own unique geographic, historic, political, and legal context. Canada’s unresolved maritime boundaries are the result of circumstances specific to each of them and not of a particular policy approach in Ottawa.

Expert Assessments

Identification of water masses in areas with complex water dynamics is a complex task, which is usually solved by the method of expert assessments. In this paper, it is proposed to use a formal procedure based on the application of the method of optimal multiparametric analysis (OMP analysis). The data of field measurements obtained in the 68th cruise of the R/V “Academician Mstislav Keldysh” in the summer of 2017 in the Barents Sea on the distribution of temperature, salinity, oxygen, silicates, nitrogen, and phosphorus concentration are used as a data for research. A comparison of the results with data on the distribution of water masses in literature based on expert assessments (Oziel et al., 2017), allows us to conclude about their close structural similarity. Some differences are related to spatial and temporal shifts of measurements. This indicates the feasibility of using the OMP analysis technique in oceanological studies to obtain quantitative data on the spatial distribution of different water masses.
