Analysis of detailed statistics shows remarkable fluctuations in the volume and composition of voyages on the Northern Sea Route (NSR) along the northern coast of Russia since international use began in 2010. There has been strong growth in destination shipping between the Arctic and ports outside the region, but transit shipping between the Pacific and the Atlantic has not experienced the growth many had anticipated. Explanations are found in international market conditions as well as in the management of the NSR, with important lessons for the future development of different shipping segments. Shipping companies from several countries took part in the period up to 2019, but they seem to have become less central in the current phase of NSR shipping, which is dominated by the transport of hydrocarbons out of the Arctic. Russia expects international transit to pick up later. However, Russia alone cannot determine the volume of international traffic: it is the international shipping industry that will assess the balance of factors and conditions, and conclude if and when the shorter Arctic routes are safe, efficient, reliable, environmentally sound and economically viable in comparison with other routes.

Today due to global climate change the Northern Sea Route is being formed along the northern coast of Russia as a new international maritime passage in the Arctic. Due to the rapid increase in the interest of regional and non-Arctic states, the scientific community and business to this transportation route, there is a need to study the prospects for cooperation between Russia and other countries on the development of the Northern Sea Route. The paper provides a detailed analysis of the interests of external players in the NSR area, taking into account the latest changes and events, while the author uses swot-analysis and a comparative analytical approach to conduct the study. The results of the study have shown that cooperation with some Arctic countries on the development of the NSR could bring mutual benefits: Canada and Russia would exchange experience on the development of similar sea routes, and Norway and Iceland would receive advantages as hubs on new routes. Non-regional countries, such as China, South Korea, Japan, Singapore and India, are interested in the NSR. For them, the Northern Sea Route is potentially shorter and safer compared to traditional routes, and it also allows to participate in projects located near its water area in science, energy and transport sectors. In turn, the participation of foreign partners is important for Russia, since it is usually accompanied by the active use of the route, the creation of large projects throughout its entire length, the attraction of serious funds, modern technologies and knowledge to the Arctic zone of the country.

Subject Shipping in the Arctic between China and Europe. Significance Climate change is leaving Arctic waters navigable for longer periods, opening a new shipping route from East Asia to Europe along Russia's northern coast. Dubbed the ‘Polar Silk Road’ (PSR) in China and 'Northern Sea Route' (NSR) in Russia, it could eventually become an alternative to the main Strait of Malacca and Suez Canal route, altering global supply chains and geopolitics. Impacts The PSR's economic viability is premised on it being a reliable and safe route; that time is still far off. Melting ice will unlock new natural resources and commercial opportunities. The foremost use of the PSR initially will probably be for shipping resources extracted from the Arctic to markets elsewhere.

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.

Ciguatera fish poisoning (CFP) is one of the most frequently reported seafood poisoning diseases. It is endemic to the tropical region and occurs most commonly in the regions around the Pacific Ocean, Indian Ocean, and Caribbean Sea. The principal toxins causing CFP are ciguatoxins (CTXs). In the Pacific region, more than 20 analogs of CTXs have been identified to date. Based on their skeletal structures, they are classified into CTX1B-type and CTX3C-type toxins. We have previously reported species-specific and regional-specific toxin profiles. In this study, the levels and profiles of CTXs in fish present in the tropical western Pacific regions were analyzed using the liquid chromatography–tandem mass spectrometry (LC–MS/MS) technique. Forty-two fish specimens, belonging to the categories of snappers, groupers, Spanish mackerel, and moray eel, were purchased from various places such as Fiji, the Philippines, Thailand, and Taiwan. Only the fish captured from Fijian coastal waters contained detectable amounts of CTXs. The toxin levels in the fish species found along the coastal regions of the Viti Levu Island, the main island in Fiji, and the toxin profiles were significantly different from those of the fish species present in other coastal regions. The toxin levels and profiles varied among the different fish samples collected from different coastal areas. Based on the toxin levels and toxin profiles, the coast was demarcated into three zones. In Zone-1, which covers the northern coast of the main island and the regions of the Malake Island and Korovau, CTXs in fish were below the detection level. In Zone-2, CTX3C-type toxins were present in low levels in the fish. CTX1B-type and CTX3C-type toxins co-occurred in the fish present in Zone-3. The toxin profiles may have reflected the variation in Gambierdiscus spp.

Ice Concentration

The Arctic sea ice concentration (SIC) in summer is a key indicator of global climate change and important information for the development of a more economically valuable Northern Sea Route. Passive microwave (PM) sensors have provided information on the SIC since the 1970s by observing the brightness temperature (TB) of sea ice and open water. However, the SIC in the Arctic estimated by operational algorithms for PM observations is very inaccurate in summer because the TB values of sea ice and open water become similar due to atmospheric effects. In this study, we developed a summer SIC retrieval model for the Pacific Arctic Ocean using Advanced Microwave Scanning Radiometer 2 (AMSR2) observations and European Reanalysis Agency-5 (ERA-5) reanalysis fields based on Random Forest (RF) regression. SIC values computed from the ice/water maps generated from the Korean Multi-purpose Satellite-5 synthetic aperture radar images from July to September in 2015–2017 were used as a reference dataset. A total of 24 features including the TB values of AMSR2 channels, the ratios of TB values (the polarization ratio and the spectral gradient ratio (GR)), total columnar water vapor (TCWV), wind speed, air temperature at 2 m and 925 hPa, and the 30-day average of the air temperatures from the ERA-5 were used as the input variables for the RF model. The RF model showed greatly superior performance in retrieving summer SIC values in the Pacific Arctic Ocean to the Bootstrap (BT) and Arctic Radiation and Turbulence Interaction STudy (ARTIST) Sea Ice (ASI) algorithms under various atmospheric conditions. The root mean square error (RMSE) of the RF SIC values was 7.89% compared to the reference SIC values. The BT and ASI SIC values had three times greater values of RMSE (20.19% and 21.39%, respectively) than the RF SIC values. The air temperatures at 2 m and 925 hPa and their 30-day averages, which indicate the ice surface melting conditions, as well as the GR using the vertically polarized channels at 23 GHz and 18 GHz (GR(23V18V)), TCWV, and GR(36V18V), which accounts for atmospheric water content, were identified as the variables that contributed greatly to the RF model. These important variables allowed the RF model to retrieve unbiased and accurate SIC values by taking into account the changes in TB values of sea ice and open water caused by atmospheric effects.

AbstractUnprecedented quantities of heat are entering the Pacific sector of the Arctic Ocean through Bering Strait, particularly during summer months. Though some heat is lost to the atmosphere during autumn cooling, a significant fraction of the incoming warm, salty water subducts (dives beneath) below a cooler fresher layer of near-surface water, subsequently extending hundreds of kilometers into the Beaufort Gyre. Upward turbulent mixing of these sub-surface pockets of heat is likely accelerating sea ice melt in the region. This Pacific-origin water brings both heat and unique biogeochemical properties, contributing to a changing Arctic ecosystem. However, our ability to understand or forecast the role of this incoming water mass has been hampered by lack of understanding of the physical processes controlling subduction and evolution of this this warm water. Crucially, the processes seen here occur at small horizontal scales not resolved by regional forecast models or climate simulations; new parameterizations must be developed that accurately represent the physics. Here we present novel high resolution observations showing the detailed process of subduction and initial evolution of warm Pacific-origin water in the southern Beaufort Gyre.

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.

AbstractThe plate tectonic cycle produces chemically distinct mid-ocean ridge basalts and arc volcanics, with the latter enriched in elements such as Ba, Rb, Th, Sr and Pb and depleted in Nb owing to the water-rich flux from the subducted slab. Basalts from back-arc basins, with intermediate compositions, show that such a slab flux can be transported behind the volcanic front of the arc and incorporated into mantle flow. Hence it is puzzling why melts of subduction-modified mantle have rarely been recognized in mid-ocean ridge basalts. Here we report the first mid-ocean ridge basalt samples with distinct arc signatures, akin to back-arc basin basalts, from the Arctic Gakkel Ridge. A new high precision dataset for 576 Gakkel samples suggests a pervasive subduction influence in this region. This influence can also be identified in Atlantic and Indian mid-ocean ridge basalts but is nearly absent in Pacific mid-ocean ridge basalts. Such a hemispheric-scale upper mantle heterogeneity reflects subduction modification of the asthenospheric mantle which is incorporated into mantle flow, and whose geographical distribution is controlled dominantly by a “subduction shield” that has surrounded the Pacific Ocean for 180 Myr. Simple modeling suggests that a slab flux equivalent to ~13% of the output at arcs is incorporated into the convecting upper mantle.

An expanded description of a little-known arctic species Montacuta spitzbergensis from the Sea of Okhotsk with new data on its morphology, ecology and geographical distribution is given. This is the first record of M. spitzbergensis from the north-western Pacific. It differs from other species of Montacuta in its large (to 8.4 mm), elongate–ovate, thick shell with wide, slightly curved hinge plate, wide, short, and shallow resilifer, and weakly developed external ligament. This species occurs in the Arctic Ocean (Spitsbergen, Barents, Kara, Laptev and Chukchi Seas) and the Pacific Ocean (Sea of Okhotsk) at depths from 9 to 232 m at a bottom temperature from −1.62°C to +2.50°C. The hinge structure of the type species of the genera Montacuta and Tellimya is also discussed.
