Bibliography , INTRODUCTION The ringed seal (Phoca hispida Schreb.) is the most widespread and, possibly, most characteristic animal of the Arctic seas in the Soviet Union. In economic importance it is preceded by the Greenland seal in the west and by the walrus in the east. Its reserves up to the present time remain almost untouched for ,a large part of the marine area of the Soviet Arctic. In the Barents and Kara seas the most intensive hunting is developed essentially along the western shore of Novaya Zemlya. In the other regions there is sporadic hunting only where there is coastal settlement. The large quantity of ringed seal and the great need for its products,which ib felt both in local areas and in the entire economy,opehs up wide possibilities for future develop- ment in the hunting of this animal. Information on the ringed seal as an object of hunting has hitherto remained on a very, low level, being based on data which have been published more than thirty years ago. The last ten years have been marked, as we know, by great progress in the many-sided study of the Soviet Arctic and its exploitation. As a result of the composite hunting and biological studies whichhnve been conducted during the last five years by numerous Soviet research workers significant though incomplete data has been accumulated on ringed seal as well. The present report sums up what is known at the present time about the biology and morphology of the northern ringed seal and about the quantitative and, in part, the qualitative indices of the obtained commercial raw material. Since the work is composite in nature, the,.author included all .of the new data which were accessible to him which had been . collected by the scientific personnel of different expeditions and winterings, particularly, by V. Antipin, M. Vladimirskaya, V. Vagin, G. Galkin, G. Gorbunov, A. Dubroyskii, N. Demme-Ryabtseya, K. Kovalev, A. Lepin, L. Leonbv, N. Mikhel, N. Provorov, G.Rutilevskii. A. Tyulin, A. Chechulin, I. YakimoVich et. al, and by hunters'and : other workers in the Arctic. IL THE MORPHOLOGIC NATURE 1. Size of Animal Since the size of the body is a changing value, it should not be recorded except in close connection with age, particularly in the periôd of intensive growth of the orgahism- After many - considerations the following age categories were adopted: 1) the offspring at birth; 2) half-year-olds; 3) year-olds; 4) older offspring not sexually mature; 5) mature Males and females. The establishment of these age groups was preceded by very laborious and long work on developing age criteria and on the rationale of the selected age categories. The incompleteness of the data, the broad limits of uncertainty concerning individual • features, the disappointing gaps in the collections - all of this complicated the work to a considerable degree and could not but - reflect on the final calculations which are cited in Table 1.

Note: The figures in brackets which are next to the average values indicate the number of measurements. The method of measurement and the designation of individual measurements were borrowed from Professor N.A. Smirnov. The zoological length (Lc) is adopted as the base (from the tip of the snout to the tip of the tail); it is determined by placing a tape.measuremarked in centimeters on the dorsal surface of the body. In addition, the total length (Lp) (the zoological length which is extended to the tip of the flippers) and a projection of the zoological length on a horizontal plain (Lcv) are used. All three methods of expressing the body length are represented in Table 1. In exàmining the Table, the following should be borne in mind.

  • Transit Passage in the Russian Arctic Straits
    International Boundaries Research Unit MARITIME BRIEFING Volume 1 Number 7 Transit Passage in the Russian Arctic Straits William V. Dunlap Maritime Briefing Volume 1 Number 7 ISBN 1-897643-21-7 1996 Transit Passage in the Russian Arctic Straits by William V. Dunlap Edited by Peter Hocknell International Boundaries Research Unit Department of Geography University of Durham South Road Durham DH1 3LE UK Tel: UK + 44 (0) 191 334 1961 Fax: UK +44 (0) 191 334 1962 e-mail: [email protected] www: http://www-ibru.dur.ac.uk Preface The Russian Federation, continuing an initiative begun by the Soviet Union, is attempting to open the Northern Sea Route, the shipping route along the Arctic coast of Siberia from the Norwegian frontier through the Bering Strait, to international commerce. The goal of the effort is eventually to operate the route on a year-round basis, offering it to commercial shippers as an alternative, substantially shorter route from northern Europe to the Pacific Ocean in the hope of raising hard currency in exchange for pilotage, icebreaking, refuelling, and other services. Meanwhile, the international law of the sea has been developing at a rapid pace, creating, among other things, a right of transit passage that allows, subject to specified conditions, the relatively unrestricted passage of all foreign vessels - commercial and military - through straits used for international navigation. In addition, transit passage permits submerged transit by submarines and overflight by aircraft, practices with implications for the national security of states bordering straits. This study summarises the law of the sea as it relates to straits used for international navigation, and then describes 43 significant straits of the Northeast Arctic Passage, identifying the characteristics of each that are relevant to a determination of whether the strait will be subject to the transit-passage regime.

  • Chronology of the Key Historical Events on the Eastern Seas of the Russian Arctic (The Laptev Sea, the East Siberian Sea, the Chukchi Sea)
    Chronology of the Key Historical Events on the Eastern Seas of the Russian Arctic (the Laptev Sea, the East Siberian Sea, the Chukchi Sea) Seventeenth century 1629 At the Yenisei Voivodes’ House “The Inventory of the Lena, the Great River” was compiled and it reads that “the Lena River flows into the sea with its mouth.” 1633 The armed forces of Yenisei Cossacks, headed by Postnik, Ivanov, Gubar, and M. Stadukhin, arrived at the lower reaches of the Lena River. The Tobolsk Cossack, Ivan Rebrov, was the first to reach the mouth of Lena, departing from Yakutsk. He discovered the Olenekskiy Zaliv. 1638 The first Russian march toward the Pacific Ocean from the upper reaches of the Aldan River with the departure from the Butalskiy stockade fort was headed by Ivan Yuriev Moskvitin, a Cossack from Tomsk. Ivan Rebrov discovered the Yana Bay. He Departed from the Yana River, reached the Indigirka River by sea, and built two stockade forts there. 1641 The Cossack foreman, Mikhail Stadukhin, was sent to the Kolyma River. 1642 The Krasnoyarsk Cossack, Ivan Erastov, went down the Indigirka River up to its mouth and by sea reached the mouth of the Alazeya River, being the first one at this river and the first one to deliver the information about the Chukchi. 1643 Cossacks F. Chukichev, T. Alekseev, I. Erastov, and others accomplished the sea crossing from the mouth of the Alazeya River to the Lena. M. Stadukhin and D. Yarila (Zyryan) arrived at the Kolyma River and founded the Nizhnekolymskiy stockade fort on its bank.

For a modern development of the operation in the northern seas it is very important to learn from the previous ice pilot experiences. PetroArctic project has gathered the information about Russian activities in the Arctic. First part of the research is a description of the five Russian Arctic Seas from the navigation point of view. Both common and unique features for each of the seas are under consideration. Trends in the development of the ships (materials and means of a stronger hull form) and navigation (preferable routes and time) have been deduced. Appreciable amount of written documentation and interviews with actual persons involved were processed. Information about extreme situations (ice drift and ice jet, icing and hummocking, ridging ice opening and closing) and special weather and ice conditions were collected from the sailors and ice pilots. Items of special interest were connected to the shipwrecks and other accidents. Data about vessel type, location and time of wrecks and damages, weather and ice conditions, description of events has been organized into a data base. For many accidents information on distinguished features and the behaviour of humans in the Arctic waters (reactions in stressful situations and reasons for deaths) has been collected.

Climate variability in the Russian Arctic in 1991-2017 is examined based on the mesurements of the air temperature at 19 meteorological stations. The average annual air temperature at the stations fluctuated relative to the climatic baseline of 1961-1990 by 0.5-4°C in 1991-2004. Since 2005, it was higher than the climatic baseline at all stations annually. The increase in the air temperature was most pronounced in the winter months from November to February at all stations (more than 15ºɋ at some stations in some years). The increase in the air temperature in the summer months was noticeably smaller. The baseline level of the average monthly air temperature from November to February was exceeded most prominently at high latitude meteorological stations located at Wiese Island, Severnaya Zemlya, and Franz Josef Land (16-17ºɋ in some years, starting with 2005). Stations located at a distance from the ocean, such as Khatanga and Tiksi, are characterized by a smaller temperature increase compared to coastal and island stations, such as Barenzburg, Wrangel Island and others. Smaller deviations of the air temperature from the baseline level are typical in the western sector of the Russian Arctic (Murmansk, Svyatoy Nose).

Main emphasis is on regional aspects of the plankton communities and their seasonal dynamics using mostly data collected between 1996 and 2001. In the zooplankton, for which most data were available, four regional aggregations were separated: (1) the rivers and estuaries of the Southern Kara Sea, (2) the south-western and (3) the central Kara Sea, and (4) the northern troughs and slope. The phytoplankton communities had a similar distribution. To provide components for detailed carbon budgets the regional dynamics of bacterial, phytoplankton and zooplankton biomass and production are described and carbon requirements of bacteria and zooplankton are estimated. For completeness a short literature review on higher trophic levels is included. Finally, recent observations of the pelago-benthic coupling are con- sidered.

The famous Norwegian polar explorer andscientist Fridtjof Nansen wrote: ``We speak about the ®rst discovery of the NorthÐbut how can we know when the ®rst man appearedin the Earth's northern regions? We know nothing except for the very last migration stages of humanity. What occurredduring these long centuries is still hidden from us'' (Nansen, 1911). Indeed, we have some evidence on Pytheas, a Greek from Massalia, who between 350 and310 bc reachedEnglandandthen a ``gloomy land''he calledThule, beyond which ``there is no sea or landor air with some mixture of all these elements hanging in space'' (Belkin, 1983). Such a perception of the earth's northern regions was preserved for many centuries andonly began to change in the 9th to 11th centuries with the appearance of ®rst the Norsemen in the Barents andWhite Seas. Between 870 and 890 ad, more than a thousandyears after the voyage of Pytheas, the Norwegian seafarer Ottar rounded the northern tip of Europe and explored the Barents and White Seas.

  • The Ringed Seal (Phoca Hispida) in the Western Russian Arctic
    The ringed seal (Phoca hispida) in the western Russian Arctic Stanislav E. Belikov and Andrei N. Boltunov, All-Russian Research Institute for Nature Protection, Znamenskoe-Sadki, Moscow 113628, Russia. ABSTRACT 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 pri­ mary habitat, the history of sealing, and a recent harvest of the species in the region. The known pri­ mary 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 con­ structed 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 ani­ mals) 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.
