A Gram-stain-negative, strictly aerobic, rod-shaped and non-motile bacterial strain, designated D-2Q-5-6T, was isolated from a soil sample collected from the Arctic region. Strain D-2Q-5-6T was found to grow at 10–43 °C (optimum, 28 °C), at pH 6.0–9.0 (pH 7.0) and in 0–5 % (w/v) NaCl (0–1 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain D-2Q-5-6T fell into the genus Sphingorhabdus and shared less than 95.8 % identity with all type strains of recognized species of this genus. The major cellular fatty acids of strain D-2Q-5-6T were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c; 31.4 %), summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c; 26.8 %) and C14 : 0 2OH (11.7 %). The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. The predominant quinone was identified as Q10. The DNA G+C content of strain D-2Q-5-6T was 64.5 mol%. Based on the results of phylogenetic analysis and distinctive phenotypic characteristics, strain D-2Q-5-6T is concluded to represent a novel species of the genus Sphingorhabdus , for which the name Sphingorhabdus soli sp. nov. is proposed. The type strain of the species is D-2Q-5-6T (=MCCC 1A06070T=KCTC 52311T).

A Gram-stain-negative, short rod-shaped, motile (by gliding) bacterial strain, designated A12T, was isolated from tundra soil collected from Ny-Ålesund, in the Arctic region of Norway. The temperature, NaCl and pH ranges for growth were 4–25 °C (optimum, 18 °C), 0–2 % (optimum, 0 %) and pH 6–9 (optimum, pH 7). Phylogenetic analysis based on 16S rRNA gene sequences revealed that the Arctic isolate belonged to the genus Pedobacter and showed highest sequence similarity (94.4 %) to Pedobacter daechungensis KCTC 12637T. The DNA G+C content (38.3 mol%), polar lipid profile, presence of sphingolipid, MK-7 as the only respiratory quinone, and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0 and iso-C17 : 0 3-OH as major fatty acids supported the allocation of strain A12T to the genus Pedobacter as a representative of a novel species, for which the name Pedobacter arcticus sp. nov. is proposed. The type strain is A12T ( = CCTCC AB 2010223T = NRRL B-59457T). Emended descriptions of the genus Pedobacter and of Pedobacter heparinus , Pedobacter daechungensis , Pedobacter terricola , Pedobacter glucosidilyticus and Pedobacter lentus are also given.

Purpose – This paper aims to deepen our understanding on circumpolar current dynamics relating to oil and gas exploitation and the role of nations in the polar development process. Additionally, it is fundamental to raise the debate about the energy development in the Arctic and the fact that the exploration of oil and gas resources in the Arctic cannot be performed with the current governance regime, policies and legal framework. Arctic-specific natural ecosystems, the presence of indigenous communities and the commercial interest in the region will require an innovative model of development based on the highest level of responsible exploitation, diplomacy, regulation and policy-making. Design/methodology/approach – This is an unexplored subject but the paper uses a review of past and recent literature, outcomes of recent “petit comités” with some of the involved parties, as a vehicle to discuss possible new approaches and paths for the future development of an innovative model of environmental governance relating to energy development in the Arctic region. Findings – This paper demonstrates the necessity of improving the current governance patterns, as the author believes that energy development will have both positive and negative impacts on micro and macro levels. The first relevant contribution of these operations in the Arctic, undoubtedly, is the benefit for energy security levels at a global platform; however, the framework built up in terms of new legal cooperation agreements, policy-making and technological innovation in different areas will define the new Arctic citizenship as well as the Arctic’s geopolitics, and, consequently, the region’s destiny. Research limitations/implications – This is an unexplored subject, as it is an unexplored region. New literature about the region dynamics is being developed, as new licensing process is ongoing, and there are more questions than answers about open space for reflection and decision-making. Important data have not been published or shared in “petit comités” due to strategic interests and confidentiality reasons. Practical implications – The major drivers of change could be described as energy security, climate change and transportation that will have a huge direct impact in the region under social, economic and environmental perspectives. The core practical implication of this reflection is the energy development model for the Arctic region. Social implications – How the Arctic’s energy resources will contribute to the global energy mix in the decades to come and the impacts of the governance regime to Arctic and non-Arctic societies is the first relevant question. Another fundamental aspect with huge social implications is how the climate changes will impact the Arctic environment and societies. These are themes that deserve more study and deeper analysis. Originality/value – The paper provides a deep reflection of the challenges and future trends involving the new frontiers of the world energy exploration. Multidisciplinary dialogue and research on all aspects of offshore oil and gas development will require a shift in the current conceptual view of the Arctic as well as in the multilateral efforts to negotiate and design an efficient Arctic governance regime that goes beyond the setting of new standards of spill prevention, preparedness and safety, but a regime that congregates the Arctic and Non-Arctic nations’ experience, workforce and leadership.

The acquisition of real-time temperature and relative humidity (RH) profiles in the Arctic is of great significance for the study of the Arctic’s climate and Arctic scientific research. However, the operational algorithm of Fengyun-3D only takes into account areas within 60°N, the innovation of this work is that a new technique based on Neural Network (NN) algorithm was proposed, which can retrieve these parameters in real time from the Fengyun-3D Hyperspectral Infrared Radiation Atmospheric Sounding (HIRAS) observations in the Arctic region. Considering the difficulty of obtaining a large amount of actual observation (such as radiosonde) in the Arctic region, collocated ERA5 data from European Centre for Medium-Range Weather Forecasts (ECMWF) and HIRAS observations were used to train the neural networks (NNs). Brightness temperature and training targets were classified using two variables: season (warm season and cold season) and surface type (ocean and land). NNs-based retrievals were compared with ERA5 data and radiosonde observations (RAOBs) independent of the NN training sets. Results showed that (1) the NNs retrievals accuracy is generally higher on warm season and ocean; (2) the root-mean-square error (RMSE) of retrieved profiles is generally slightly higher in the RAOB comparisons than in the ERA5 comparisons, but the variation trend of errors with height is consistent; (3) the retrieved profiles by the NN method are closer to ERA5, comparing with the AIRS products. All the results demonstrated the potential value in time and space of NN algorithm in retrieving temperature and relative humidity profiles of the Arctic region from HIRAS observations under clear-sky conditions. As such, the proposed NN algorithm provides a valuable pathway for retrieving reliably temperature and RH profiles from HIRAS observations in the Arctic region, providing information of practical value in a wide spectrum of practical applications and research investigations alike.All in all, our work has important implications in broadening Fengyun-3D’s operational implementation range from within 60°N to the Arctic region.
