  • Northern Sea Route Cargo Flows and Infrastructure- Present State And
    Northern Sea Route Cargo Flows and Infrastructure – Present State and Future Potential By Claes Lykke Ragner FNI Report 13/2000 FRIDTJOF NANSENS INSTITUTT THE FRIDTJOF NANSEN INSTITUTE Tittel/Title Sider/Pages Northern Sea Route Cargo Flows and Infrastructure – Present 124 State and Future Potential Publikasjonstype/Publication Type Nummer/Number FNI Report 13/2000 Forfatter(e)/Author(s) ISBN Claes Lykke Ragner 82-7613-400-9 Program/Programme ISSN 0801-2431 Prosjekt/Project Sammendrag/Abstract The report assesses the Northern Sea Route’s commercial potential and economic importance, both as a transit route between Europe and Asia, and as an export route for oil, gas and other natural resources in the Russian Arctic. First, it conducts a survey of past and present Northern Sea Route (NSR) cargo flows. Then follow discussions of the route’s commercial potential as a transit route, as well as of its economic importance and relevance for each of the Russian Arctic regions. These discussions are summarized by estimates of what types and volumes of NSR cargoes that can realistically be expected in the period 2000-2015. This is then followed by a survey of the status quo of the NSR infrastructure (above all the ice-breakers, ice-class cargo vessels and ports), with estimates of its future capacity. Based on the estimated future NSR cargo potential, future NSR infrastructure requirements are calculated and compared with the estimated capacity in order to identify the main, future infrastructure bottlenecks for NSR operations. The information presented in the report is mainly compiled from data and research results that were published through the International Northern Sea Route Programme (INSROP) 1993-99, but considerable updates have been made using recent information, statistics and analyses from various sources.

Over a decade (2003-2015) of satellite data of sea-ice extent, sea surface temperature (SST), and methane 11 (CH4) concentrations in lower troposphere over 10 focus areas within the Barents and Kara Seas (BKS) were 12 analyzed for anomalies and trends relative to the Barents Sea. Large positive CH4 anomalies were discovered around 13 Franz Josef Land (FJL) and offshore west Novaya Zemlya in early fall. Far smaller CH4 enhancement was found 14 around Svalbard, downstream and north of known seabed seepage. SST increased in all focus areas at rates from 15 0.0018 to 0.15 °C yr-1, CH4 growth spanned 3.06 to 3.49 ppb yr-1. 16 The strongest SST increase was observed each year in the southeast Barents Sea in June due to strengthening of 17 the warm Murman Current (MC), and in the south Kara Sea in September. The southeast Barents Sea, the south 18 Kara Sea and coastal areas around FJL exhibited the strongest CH4 growth over the observation period.

Prior to this development, small offshore islands were of central importance for marine related activity due to their proximity to fishing grounds. This article presents four settlements on small and “marginal” islands in Arctic Norway from 68◦19’ to 71◦05’Nlatitude as cases that illustrate the centrality of such locations in a maritime context since the Viking Age (AD 800–1050).

  • History of Radiation and Nuclear Disasters in the Former USSR
    History of radiation and nuclear disasters in the former USSR M.V.Malko Institute of Power Engineering National Academy of Sciences of Belarus Akademicheskaya Str.15, Minsk, 220 000, Republic of Belarus E-mail: [email protected] Abstracts. The report describes the history of radiation and nuclear accidents in the former USSR. These accidents accompanied development of military and civilian use of nuclear energy. Some of them as testing of the first Soviet nuclear, Kyshtym radiation accident, radiation contamination of the Karachai lake and the Techa river, nuclear accidents at the Soviet submarine on August 10, 1985 in the Chazhma Bay (near Vladivostok) as well as nuclear accidents on April 26, 1986 at the Chernobyl NPP were of large scale causing significant radiological problems for many hundreds thousands of people. There were a number of important reasons of these and other accidents. The most important among them were time pressure by development of nuclear weapon, an absence of required financial and material means for adequate management of problems of nuclear and radiation safety, and inadequate understanding of harmful interaction of ionizing radiation on organism as well as a hypersecrecy by realization of projects of military and civilian use of nuclear energy in the former USSR. Introduction. The first nuclear reactor in the USSR reached the critical state on the 25 December 1946 [1] or 4 years later than reactor constructed by Enrico Fermi [2]. The first Soviet reactor was developed at the Laboratory N2 in Moscow (later I.V.Kurchatov Institute of Atomic Energy). This was a very important step in a realization of the Soviet military atomic program that began in September 1942.

The basic directions for reducing the anthropogenic impact of the spent booster of the first stage of the «Irtysh» type LV in the areas of falling are: determination of optimal areas for the spent booster to fall in selected areas of the FA with the highest stability and minimum cost of works on restoring the soil state — (A); controlled descent of the spent booster after separation from the LV to the designated section of the fall with an accuracy not exceeding the size of the selected optimal section — (B). To solve problems of direction A, it is proposed to create an additional information and analytical system of the area of falling.

  • Appendix I Lunar and Martian Nomenclature
    APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject.

Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.
