    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.
  • Consensus Statement

    Consensus Statement

    Arctic Climate Forum Consensus Statement 2020-2021 Arctic Winter Seasonal Climate Outlook (along with a summary of 2020 Arctic Summer Season) CONTEXT Arctic temperatures continue to warm at more than twice the global mean. Annual surface air temperatures over the last 5 years (2016–2020) in the Arctic (60°–85°N) have been the highest in the time series of observations for 1936-20201. Though the extent of winter sea-ice approached the median of the last 40 years, both the extent and the volume of Arctic sea-ice present in September 2020 were the second lowest since 1979 (with 2012 holding minimum records)2. To support Arctic decision makers in this changing climate, the recently established Arctic Climate Forum (ACF) convened by the Arctic Regional Climate Centre Network (ArcRCC-Network) under the auspices of the World Meteorological Organization (WMO) provides consensus climate outlook statements in May prior to summer thawing and sea-ice break-up, and in October before the winter freezing and the return of sea-ice. The role of the ArcRCC-Network is to foster collaborative regional climate services amongst Arctic meteorological and ice services to synthesize observations, historical trends, forecast models and fill gaps with regional expertise to produce consensus climate statements. These statements include a review of the major climate features of the previous season, and outlooks for the upcoming season for temperature, precipitation and sea-ice. The elements of the consensus statements are presented and discussed at the Arctic Climate Forum (ACF) sessions with both providers and users of climate information in the Arctic twice a year in May and October, the later typically held online.

Geologicheskaya 49, Novosibirsk, 630010, Russia Received 25 May 2010; accepted 7 October 2010 Abstract The resistivity pattern at the site of the “Crystal” underground nuclear explosion (Daldyn–Alakit district of Yakutia) of 1974 which led to an accident has been imaged using TEM data. The local background pattern corresponds to a three- or four-layer earth with a conductor at the base. The uppermost layer, with a resistivity of tens to hundreds of ohm ⋅ m, has its bottom at 190–260 m asl and consists of perennially frozen Late Cambrian carbonates. The resistivity structure of shallow subsurface at the blast epicenter remained unperturbed though being subject to mechanic and thermal effects. The bottom of the second layer is at 20 to 190 m below the sealevel and its resistivity is 7–10 ohm ⋅ m. It is composed of frost-bound and unfrozen cold rocks that belong to a Late Cambrian water-bearing sequence (an aquifer).

    Sediment transport to the Laptev Sea-hydrology and geochemistry of the Lena River V. RACHOLD, A. ALABYAN, H.-W. HUBBERTEN, V. N. KOROTAEV and A. A, ZAITSEV Rachold, V., Alabyan, A., Hubberten, H.-W., Korotaev, V. N. & Zaitsev, A. A. 1996: Sediment transport to the Laptev Sea-hydrology and geochemistry of the Lena River. Polar Research 15(2), 183-196. This study focuses on the fluvial sediment input to the Laptev Sea and concentrates on the hydrology of the Lena basin and the geochemistry of the suspended particulate material. The paper presents data on annual water discharge, sediment transport and seasonal variations of sediment transport. The data are based on daily measurements of hydrometeorological stations and additional analyses of the SPM concentrations carried out during expeditions from 1975 to 1981. Samples of the SPM collected during an expedition in 1994 were analysed for major, trace, and rare earth elements by ICP-OES and ICP-MS. Approximately 700 h3freshwater and 27 x lo6 tons of sediment per year are supplied to the Laptev Sea by Siberian rivers, mainly by the Lena River. Due to the climatic situation of the drainage area, almost the entire material is transported between June and September. However, only a minor part of the sediments transported by the Lena River enters the Laptev Sea shelf through the main channels of the delta, while the rest is dispersed within the network of the Lena Delta. Because the Lena River drains a large basin of 2.5 x lo6 km2,the chemical composition of the SPM shows a very uniform composition.

    Mikhail Gorbachev's Speech in Murmansk at the Ceremonial Meeting on the Occasion of the Presentation of the Order of Lenin and the Gold Star to the City of Murmansk

    MIKHAIL GORBACHEV'S SPEECH IN MURMANSK AT THE CEREMONIAL MEETING ON THE OCCASION OF THE PRESENTATION OF THE ORDER OF LENIN AND THE GOLD STAR TO THE CITY OF MURMANSK Murmansk, 1 Oct. 1987 Indeed, the international situation is still complicated. The dangers to which we have no right to turn a blind eye remain. There has been some change, however, or, at least, change is starting. Certainly, judging the situation only from the speeches made by top Western leaders, including their "programme" statements, everything would seem to be as it was before: the same anti-Soviet attacks, the same demands that we show our commitment to peace by renouncing our order and principles, the same confrontational language: "totalitarianism", "communist expansion", and so on. Within a few days, however, these speeches are often forgotten, and, at any rate, the theses contained in them do not figure during businesslike political negotiations and contacts. This is a very interesting point, an interesting phenomenon. It confirms that we are dealing with yesterday's rhetoric, while real- life processes have been set into motion. This means that something is indeed changing. One of the elements of the change is that it is now difficult to convince people that our foreign policy, our initiatives, our nuclear-free world programme are mere "propaganda". A new, democratic philosophy of international relations, of world politics is breaking through. The new mode of thinking with its humane, universal criteria and values is penetrating diverse strata. Its strength lies in the fact that it accords with people's common sense.

DOI: 10.1515/orhu-2018-0030 Abstract We describe the migration pathways of 12 Peregrine Falcons Falco peregrinus cali­ dus breeding on the Yamal Peninsula, Russia. Overall, we tracked 30 complete (17 autumn and 13 spring) and 5 incomplete seasonal migration routes. Winter ranges extended from the Atlantic coast of southern Portugal in the west to Kish Island in the Arabian Gulf in the east, and from Krasnodar in southern Russia in the north to South Sudan. Eight birds were tracked to their wintering sites, with migration pathways ranging from 3,557 km to 8,114 km, taking 14 to 61 days to complete. Birds spent an average of 190 days in their winter ranges (range 136 to 212 days, N = 14), and departure on spring migration took place in April. The home ranges used by win- tering Peregrines were varied including coastal habitats, agricultural landscapes, savannah, desert and an urban city. Departure from breeding areas took place in September with birds returning in May. Peregrines exhibited a high degree of fidelity to their winter ranges, with four birds tracked over three successive migrations until the 2012 breeding season.

Abstract Background: Broad-scale phylogeographic studies of freshwater organisms provide not only an invaluable framework for understanding the evolutionary history of species, but also a genetic imprint of the paleo- hydrological dynamics stemming from climatic change. Few such studies have been carried out in Siberia, a vast region over which the extent of Pleistocene glaciation is still disputed.
