Transits of the Northwest Passage to End of the 2019 Navigation Season Atlantic Ocean ↔ Arctic Ocean ↔ Pacific Ocean
TRANSITS OF THE NORTHWEST PASSAGE TO END OF THE 2019 NAVIGATION SEASON ATLANTIC OCEAN ↔ ARCTIC OCEAN ↔ PACIFIC OCEAN R. K. Headland and colleagues 12 December 2019 Scott Polar Research Institute, University of Cambridge, Lensfield Road, Cambridge, United Kingdom, CB2 1ER. <[email protected]> The earliest traverse of the Northwest Passage was completed in 1853 but used sledges over the sea ice of the central part of Parry Channel. Subsequently the following 314 complete maritime transits of the Northwest Passage have been made to the end of the 2019 navigation season, before winter began and the passage froze. These transits proceed to or from the Atlantic Ocean (Labrador Sea) in or out of the eastern approaches to the Canadian Arctic archipelago (Lancaster Sound or Foxe Basin) then the western approaches (McClure Strait or Amundsen Gulf), across the Beaufort Sea and Chukchi Sea of the Arctic Ocean, through the Bering Strait, from or to the Bering Sea of the Pacific Ocean. The Arctic Circle is crossed near the beginning and the end of all transits except those to or from the central or northern coast of west Greenland. The routes and directions are indicated. Details of submarine transits are not included because only two have been reported (1960 USS Sea Dragon, Capt. George Peabody Steele, westbound on route 1 and 1962 USS Skate, Capt. Joseph Lawrence Skoog, eastbound on route 1). Seven routes have been used for transits of the Northwest Passage with some minor variations (for example through Pond Inlet and Navy Board Inlet) and two composite courses in summers when ice was minimal (transits 149 and 167). -

Ice algae and phytoplankton are major C sources for Arctic benthic consumers, but climate change-mediated loss of summer sea ice is predicted to change Arctic marine primary production by increasing phytoplankton and reducing ice algal contributions. To investigate the impact of changing algal C sources on benthic C processing, 2 isotope tracing experiments on 13C-labelled ice algae and phytoplankton were conducted in the North Water Polynya (NOW; 709 m depth) and Lancaster Sound (LS; 794 m) in the Canadian Arc- tic, during which the fate of ice algal (CIA) and phytoplankton (CPP) C added to sediment cores was traced over 4 d. No difference in sediment community oxygen consumption (SCOC, indicative of total C turnover) between the background measurements and ice algal or phytoplankton cores was found at either site. Most of the processed algal C was respired, with significantly more CPP than CIA being released as dissolved inorganic C at both sites. Macroinfaunal uptake of algal C was minor, but bacterial assimilation accounted for 33−44% of total algal C processing, with no differences in bacterial uptake of CPP and CIA found at either site. -
Eurythenes Gryllus Reveal a Diverse Abyss and a Bipolar Species

Previous studies, however, indicated the existence of several genetically and morphologically divergent lineages, questioning the assumption of its cosmopolitan and eurybathic distribution. For the first time, its genetic diversity was explored at the global scale (Arctic, Atlantic, Pacific and Southern oceans) by analyzing nuclear (28S rDNA) and mitochondrial (COI, 16S rDNA) sequence data using various species delimitation methods in a phylogeographic context. Nine putative species-level clades were identified within £ gryllus. A clear distinction was observed between samples collected at bathyal versus abyssal depths, with a genetic break occurring around 3,000 m. Two bathyal and two abyssal lineages showed a widespread distribution, while five other abyssal lineages each seemed to be restricted to a single ocean basin. -
Arctic Seabirds and Shrinking Sea Ice: Egg Analyses Reveal the Importance
www.nature.com/scientificreports OPEN Arctic seabirds and shrinking sea ice: egg analyses reveal the importance of ice-derived resources Fanny Cusset1*, Jérôme Fort2, Mark Mallory3, Birgit Braune4, Philippe Massicotte1 & Guillaume Massé1,5 In the Arctic, sea-ice plays a central role in the functioning of marine food webs and its rapid shrinking has large efects on the biota. It is thus crucial to assess the importance of sea-ice and ice-derived resources to Arctic marine species. Here, we used a multi-biomarker approach combining Highly Branched Isoprenoids (HBIs) with δ13C and δ15N to evaluate how much Arctic seabirds rely on sea-ice derived resources during the pre-laying period, and if changes in sea-ice extent and duration afect their investment in reproduction. Eggs of thick-billed murres (Uria lomvia) and northern fulmars (Fulmarus glacialis) were collected in the Canadian Arctic during four years of highly contrasting ice conditions, and analysed for HBIs, isotopic (carbon and nitrogen) and energetic composition. Murres heavily relied on ice-associated prey, and sea-ice was benefcial for this species which produced larger and more energy-dense eggs during icier years. In contrast, fulmars did not exhibit any clear association with sympagic communities and were not impacted by changes in sea ice. Murres, like other species more constrained in their response to sea-ice variations, therefore appear more sensitive to changes and may become the losers of future climate shifts in the Arctic, unlike more resilient species such as fulmars. Sea ice plays a central role in polar marine ecosystems; it drives the phenology of primary producers that con- stitute the base of marine food webs. -

Perceived Implications of Privatization for Canadian Coast Guard Services, Principally Arctic Icebreaking
Perceived Implications Of Privatization For Canadian Coast Guard Services, Principally Arctic Icebreaking by James Parsons A thesis submitted to the University of Plymouth in partial fulfilment for the degree of DOCTOR OF PHILOSOPHY International Shipping and Logistics Group School of Management, Plymouth Business School August 2009 Abstract James Parsons Perceived Implications Of Privatization For Canadian Coast Guard Services, Principally Arctic Icebreaking Climate change, with the possibility of an ice free Arctic ocean by 2015, has generated a renewed interest in the Arctic. This interest is being driven by the possibility of easier access to the abundant supply of resources such as oil, gas, minerals, and fisheries. Interest in Arctic tourism is also growing. Retreating sea ice will provide opportunities to avail of shorter routes for maritime traffic to and from Asia, North America, and Asia via the Arctic Ocean and Northwest Passage. In addition, the rate of population growth of local inhabitants in the Canadian Arctic is the fastest in Canada and one of the fastest in the world. A growing population will increase the demand for sealift resupply to Canada's northern communities. This work presents the first attempt to examine the role of privatization of icebreaking services in light of the present and projected shortages of infrastructure to support development in the Arctic. A unique combination of multiple methods within marine transportation, comprising of Delphi, grounded theory, and quantitative survey, is applied to investigate the potential for private involvement in the delivery of icebreaking services in the Canadian Arctic. This includes a novel application of Strauss and Corbin's Grounded Theory approach to develop hypotheses and relationships grounded in expert opinion. -

The first (No. 138) deals with Kwantung Arm's wartime vigil throughout Manchuria in prepa- ration for operations. The second (No. 154) deals with actual military operations against Soviet forces on the eastern front. This monograph, No. 155, covers operations in the northern and western parts of Manchuria and also in northern Korea. Like No. 154, this monograph is actually a collection of closely related sub-monographs, each a separate--but by no means complete--study in itself. -

Credit: Woods Hole Oceanographic Institution - Advanced Imaging and Visualization Laboratory. 1 Abstract In accordance with the National Environmental Policy Act (NEPA, 42 U.S.C. 4321 et seq.) and the National Marine Sanctuaries Act (NMSA, 16 U.S.C. 1434 et seq.), the National Oceanic and Atmospheric Administration’s (NOAA) Office of National Marine Sanctuaries (ONMS) has prepared a Draft Environmental Impact Statement (DEIS) that considers alternatives for the proposed designation of Wisconsin - Lake Michigan as a National Marine Sanctuary. The proposed action addresses NOAA’s responsibilities under the NMSA to identify, designate, and protect areas of the marine and Great Lakes environment with special national significance due to their conservation, recreational, ecological, historical, scientific, cultural, archaeological, educational, or aesthetic qualities as national marine sanctuaries. ONMS has developed five alternatives for the designation, and the DEIS evaluates the environmental consequences of each under NEPA. The DEIS also serves as a resource assessment under the NMSA, documenting present and potential uses of the areas considered in the alternatives. -
