Status, number, and monitoring of the common eider (Somateria mollissima) population in the barents sea and the White Sea

The purpose of the article is to introduce into scientific circulation little-known and controversial objects made of stones discovered during our field surveys in 2019 on the Tersk Coast of the White Sea near the Khlebnaya River. The monument consists of 27 boulder structures of four types: ring-shaped layouts with a recess in the center –– boulder pits (24), “seid”, “pile”, a flat boulder with stones laid on it. Boulder pits within the borders of the Russian Federation are found in the coastal zone of the Western and Northern White Sea regions and the Barents Sea. The distribution of such objects is noted in Finnmark and Finnish Lapland and correlates with the area of historical settlement of local Sami groups. We tend to interpret the “boulder pits” as objects associated with non-Christian cult practices, possibly of a funerary nature.

The polyphenol content in the brown algae of the Barents, White Seas, as well as the water areas of the Northwest Atlantic (the Norwegian Sea, the Faxflow bay of the Atlantic Ocean) located in Russia, Norway, Greenland, and Iceland are compared. Algae of the following species were used for this study: Fucus vesiculosus, Fucus spiralis, Fucus serratus, Ascophyllum nodosum, Fucus evanescens. It was found that the most productive raw materials for the extraction of polyphenolic compounds are brown algae F. vesiculosus, growing in Zavalishin Bay of the Barents Sea (Russia): the highest polyphenol content (14.4%) in the summer of 2019 was noted here. Polyphenols detected in F. vesiculosus in the summer from the White Sea on about. Great burnt (13.3%) (Russia), as well as in the Norwegian Sea, Cape Sydspissen (11.6%) (Norway). The minimum content of polyphenols was found in F. spiralis (0.7% dry mass) on the coast of Iceland (Faxflow bay), a low content of polyphenols was characteristic of all types of algae from this location (0.7–2.4%). Three-way analysis of variance (MANOVA) on the example of three types of algae (F. vesiculosus, F. spiralis, A. nodosum) showed that all the studied factors (place of collection, type of algae, fertile phase) are significant. The most significant factor affecting the accumulation of polyphenols by brown algae is the location of algae growth. The high content of polyphenols in the types of algae we studied from Russian water areas allows us to recommend their use as food and medicinal raw materials, as well as raw materials for biologically active additives.

Russian priority - the study of storm surges and wave climate in the Arctic seas due to the active development of offshore oil and gas. Researching the formation of storm surge and wave are necessary for the design and construction of facilities in the coastal zone, as well as for the safety of navigation. An inactive port ensues considerable economic losses. It is important to study the variability of storm surges, wave climate in the past and forecast the future. Consequently, this information would be used for planning the development of the Arctic in accordance with the development programme 2020. Mathematical modeling is used to analyze the characteristics of storm surges and wave climate formation from 1979 to 2010 in the White and Barents Seas. Calculation of storm surge heights in the seas is performed using model AdCirc on an unstructured grid with a 20 km pitch in the Barents Sea and 100 m in the White Sea. The model AdCirc used data of wind field reanalysis CFSv2. The simulation of storm surge was conducted with/without pressure, sea state, tides. A non-linear interaction of the surge and tide during the phase of destruction storm surge was detected. Calculation of the wave climate performed using SWAN spectral wave model on unstructured grids. Spatial resolution is 500 m-5 km for the White Sea and 10-20 km for the Barents Sea. NCEP/CFSR (~0.3°) input wind forcing was used. The storminess of the White Sea tends to increase from 1979 to 1991, and then decrease to minimum at 2000 and increase again till 2010.

Atka mackerel, Pleurogrammus monopterygius was proposed for acclimatization to the Barents Sea long ago (Russ, 1958) and has been thoroughly studied in this regard. However, the number of experimental works by the transplantation of Atka mackerel from Kamchatka to the Barents Sea was small and their scale is insignificant. A total of 2 attempts were made in the 70s and 80s. The last time in 1982-1984, 6.5 millions of Atka mackerel caviar was transported from Kamchatka to Murmansk. Unfortunately, the systematic works by introduction was stopped. Meanwhile, the experience of acclimatization of Atka mackerel is very valuable not only for its practical orientation, which has in the future the additional production of fish in the Barents Sea, but also for a certain contribution to the development of the theory of acclimatization. The article provides information on the two repeated capture of Atka mackerel in the Barents Sea and six repeated in the White Sea. It is advisable to purposefully check the information on the White Sea; it is possible that the short time of the stay of adults Atka mackerel in the reservoir during the breeding period does not allow them to be identified during the annual ichthyological survey of the White Sea. It would be useful to catch of the Teribersky Cape of the Barents Sea, where adult Atka mackerel can be found during the breeding season. If the facts will not be confirmed, then our supposition remains true that the scale of work on the transplantation of Atka mackerel caviar was insignificant and the amount of imported caviar is small

Harp seal pups (4 ind.) were caught and marked with satellite telemetry transmitters (STT) in the White Sea in March-April 2010, the average tenure of STT was 226 ± 51.7 (103.6) days. In April the seals on the growth stage of "beater" left the White Sea on the drifting ice. In the Barents Sea the seals migrated north through the eastern part of the Barents Sea. Seals came to the northernmost point of their migration route, i.e. edge of the pack ice in the August – October period. One seal came out to the Greenland Sea. Seals’ return migration was in winter along the Novaya Zemlya to the south-eastern part of the Barents Sea. Result data of marking showed harp seal juveniles during the first seasonal migration may leave the traditional feeding areas, and during the return migration may not come to molt to the White Sea. According to satellite telemetry data the Czech Bay (Barents Sea) can be one of the molt areas of harp seal juveniles.

This paper presents a review of available published and unpublished material on the ringed seal (Phoca hispida) in the western part of the Russian Arctic, including the White, Barents and Kara seas. The purpose of the review is to discuss the status of ringed seal stocks in relation to their primary habitat, the history of sealing, and a recent harvest of the species in the region. The known primary breeding habitats for this species are in the White Sea, the south-western part of the Barents Sea, and in the coastal waters of the Kara Sea, which are seasonally covered by shore-fast ice. The main sealing sites are situated in the same areas. Female ringed seals become mature by the age of 6, and males by the age of 7. In March-April a female gives birth to one pup in a breeding lair constructed in the shore-fast ice. The most important prey species for ringed seals in the western sector of the Russian Arctic are pelagic fish and crustaceans. The maximum annual sealing level for the region was registered in the first 70 years of the 20th century: the White Sea maximum (8,912 animals) was registered in 1912; the Barents Sea maximum (13,517 animals) was registered in 1962; the Kara Sea maximum (13,200 animals) was registered in 1933. Since the 1970s, the number of seals harvested has decreased considerably. There are no data available for the number of seals harvested annually by local residents for their subsistence.
