Simplified Procedure

The article is devoted to the analysis of the role of the Northern Sea Route (NSR) in the socio-economic development of the Arctic zone of Russia. The authors believe that climate change, gradually leading to the melting of polar ice, opens up new opportunities for the development of Arctic resources and navigation in the seas of the Arctic Ocean. Of particular interest to the NSR are non-Arctic countries, critically dependent on the supply of foreign mineral and carbon resources, as well as on the export of their goods to Europe. Among them, China stands out, considering the NSR as the Arctic Blue Economic Corridor as part of the global Silk Road system. The NSR is intended to become an essential tool for further development of the Arctic zone of Russia. Development of port infrastructure and creation of a modern ocean and maritime fleet will accelerate the pace of socio-economic development of this strategically important region. To do this, it is necessary to adopt a federal law on special system of preferences for investors, including foreign ones, implementing their projects in the Arctic. Among such preferences there are preferential profit tax rates, reduction in Mineral Extraction Tax (MET) rates, a declarative procedure for VAT refunds, a simplified procedure for granting land plots and unchanged conditions for the implementation of investment projects. In addition, it is important to make the NSR safe and profitable both in terms of quality of service and of price for the shippers. In particular, the payment for icebreakers’ escort of vessels should be competitive and reasonable. The largest Russian private and state-owned companies should be involved into Arctic projects. It is important to synchronize the Arctic oil and gas projects with nuclear and LNG icebreakers’ construction, as well as with the launch of two logistics hubs in Murmansk and Kamchatka. In this case, year-round NSR navigation will be organized, which will ensure the high competitiveness of Russian products supplied to the Asian Pacific markets.

The concept of a new approach to environmental assessment is offered in the system of integrated management of the resource and environmental safety of the coastal area of the Black Sea. The studies of the season and daily changeability in the bioluminescence field in the Sevastopol coastal waters has been conducted. For the first time considerable differences in the bioluminescence field seasonal changes in the surface and deep water layers and the reasons conditioning this phenomenon have been shown, using a method of multidimensional statistical analysis. The bioluminescence field vertical profile change in the Black sea coastal waters in the autumn period at night has been studied. It has been shown that according to the character of bioluminescence parameters dynamics a water column can be divided into layers: upper (0 – 35 m) and deep water (36 – 60 m). It has been revealed that life rhythms of the plankton community are the main reason for the bioluminescence field intensity variability. It has been revealed that 14-hour periodicity of the bioluminescence field is related to the changes in light and its variations with 2,5…4,5 hours are conditioned by planktonts endogenous daily rhythms. And here biotic factors effect mostly periodicity of the bioluminescence field intensity increase and fall down at the dark time of the day. Abiotic factors are of less importance in circadian rhythmic of the bioluminescence field in the neritic zone.

PurposeThe purpose of this study is to evaluate the profitability of the Northern Sea Route (NSR) as a shipping lane from the financial perspective of shipping companies under post 2020 sulphur regulations.Design/methodology/approachThis study develops profit estimation model, and the profitability of the NSR is assessed for a Handymax Medium Range (MR) tanker vessel using scenarios in combination with spot market earning levels, the regulation compliance method and destination ports. The required freight rates are calculated to justify the decision of shipowners to transit a tanker from the Baltic spot market to the NSR navigation.FindingsResults suggest that the required freight rates from the Arctic trade to justify the transit to the NSR are higher than the actual agreed rates in the past, which implies low viability of the NSR as a regular shipping lane. It was also found that the required freight rates are affected by the spot market earning levels, compliance method and duration of the voyage.Research limitations/implicationsThis study takes a new approach on assessing the NSR viability by comprehensively assessing the annual profitability and including the spot market trade as an opportunity cost for the NSR shipping. Despite various scenarios used in this study, a sensitivity analysis would be useful for future research.Practical implicationsThis study suggests how much freight rates a shipping company would need to charge if it were to offer tanker shipping services to four major Asian ports while simultaneously operating at the Baltic Sea during the remainder of the year.Originality/valueThis study adopts a market-oriented approach by incorporating both earnings and costs (including opportunity costs) in the profitability model rather than merely analyzing the total cost of shipping via the NSR. This study also analyzes impact of IMO 2020 Sulphur regulation on the NSR profitability.

INTRODUCTIONOphiacantha bidentata (Retzius) is a widespread arctic-boreal ophiuroid with a circumpolar distribution in the shallow waters of the Arctic seas and penetrating into the deep sea of the.North Atlantic and North Pacific (Mortensen, 1927, 1933a; D'yakonov, 1954). Early observations of this species were confined to defining zoogeo-graphical and taxonomic criteria including the separation of deep water specimens as the variety fraterna (Farran, 1912; Grieg, 1921; Mortensen, 1933a). Mortensen (1910) and Thorson (1936, pp. 18–26) noted the large eggs (o.8 mm diameter) in specimens from Greenland and Thorson (1936) proposed that this species had ‘big eggs rich in yolk, shed directly into the sea. Much reduced larval stage or direct development’. This evidence is supported by observations of O. bidentata from the White and Barents Seas (Semenova, Mileikovsky & Nesis, 1964; Kaufman, 1974)..

The Arctic Mediterranean Seas constitute an oceanic region in which the thermohaline circulation has a strong advective component and deep ventilation processes are very active relative to other oceanic areas. Details of the nature of these circulation and ventilation processes have been revealed through use of Cs and Sr isotopes from bomb-fallout and nuclear-waste sources as ocean tracers. In both cases, their regional input is dominated by advective supply in the Norwegian Atlantic Current and Norwegian Coastal Current, respectively. The different temporal, spatial, and compositional input patterns of these tracers have been used to study different facets of the regional circulation. These input differences and some representative applications of the use of these tracers are reviewed. The data discussed derive from samples collected both from research vessels and from Arctic ice camps. The topics addressed include: ( a ) the role of Arctic Intermediate Water as source, supplying recent surface water to North Atlantic Deep Water via the Denmark Strait overflow; ( b ) deep convective mixing in the Greenland Sea; ( c ) circulation or recirculation of Atlantic water in the Arctic basins; and ( d ) the role of Arctic shelfwaters in the ventilation of intermediate and deep water in the Eurasian and Canadian basins.

Meridional Overturning

Abstract Analyses of a 500-yr control integration with the non-flux-adjusted coupled atmosphere–sea ice–ocean model ECHAM5/Max-Planck-Institute Ocean Model (MPI-OM) show pronounced multidecadal fluctuations of the Atlantic overturning circulation and the associated meridional heat transport. The period of the oscillations is about 70–80 yr. The low-frequency variability of the meridional overturning circulation (MOC) contributes substantially to sea surface temperature and sea ice fluctuations in the North Atlantic. The strength of the overturning circulation is related to the convective activity in the deep-water formation regions, most notably the Labrador Sea, and the time-varying control on the freshwater export from the Arctic to the convection sites modulates the overturning circulation. The variability is sustained by an interplay between the storage and release of freshwater from the central Arctic and circulation changes in the Nordic Seas that are caused by variations in the Atlantic heat and salt transport. The relatively high resolution in the deep-water formation region and the Arctic Ocean suggests that a better representation of convective and frontal processes not only leads to an improvement in the mean state but also introduces new mechanisms determining multidecadal variability in large-scale ocean circulation.
