The marine molluscan fauna of the Prince Creek Formation near Ocean Point, northern Alaska, is of Danian age. It is the only diverse and abundant Danian molluscan fauna known from the Arctic Ocean realm, and is the first evidence for an indigenous Paleocene shallow-water biota within a discrete Arctic Ocean Basin faunal province.A high percentage of endemic species, and two endemic genera, emphasize the degree to which the Arctic Ocean was geographically isolated from the world ocean during the earliest Tertiary. Many of the well-preserved Ocean Point mollusks, however, also occur in Danian faunas of the North American Western Interior, the Canadian Arctic Islands, Svalbard, and northwestern Europe, and are the basis for relating this Arctic Ocean fauna to that of the Danian world ocean.The Arctic Ocean was a Danian refugium for some genera that became extinct elsewhere during the Jurassic and Cretaceous. At the same time, this nearly landlocked ocean fostered the evolution of new taxa that later in the Paleogene migrated into the world ocean by way of the northeastern Atlantic. The first Cenozoic occurrences are reported for the bivalves Integricardium (Integricardium), Oxytoma (Hypoxytoma), Placunopsis, Tancredia (Tancredia), and Tellinimera, and the oldest Cenozoic records given for the bivalves Gari (Garum), Neilo, and Yoldia (Cnesterium). Among the 25 species in the molluscan fauna are four new gastropod species, Amauropsis fetteri, Ellipsoscapha sohli, Mathilda (Fimbriatella) amundseni, and Polinices (Euspira) repenningi, two new bivalve genera, Arcticlam and Mytilon, and 15 new bivalve species, Arcticlam nanseni, Corbula (Caryocorbula) betsyae, Crenella kannoi, Cyrtodaria katieae, Gari (Garum) brouwersae, Integricardium (Integricardium) keenae, Mytilon theresae, Neilo gryci, Nucula (Nucula) micheleae, Nuculana (Jupiteria) moriyai, Oxytoma (Hypoxytoma) hargrovei, Placunopsis rothi, Tancredia (Tancredia) slavichi, Tellinimera kauffmani, and Yoldia (Cnesterium) gladenkovi.

Abstract. The World Ocean Database (WOD) contains over 1.3 million oceanographic casts collected in the Arctic Ocean basin and its surrounding marginal seas. The data come from many submitters and countries, and were collected using a variety of instruments and platforms. These data, along with the derived products World Ocean Atlas (WOA) and the Arctic Regional Climatologies, are uniquely useful – the data are presented in a standardized, easy to use format and include metadata and quality control information. Collecting data in the Arctic Ocean is challenging, and coverage in space and time ranges from excellent to nearly non-existent. WOD has compiled the most complete collection of Arctic Ocean profile data, ideal for oceanographic, environmental and climatic analyses (https://doi.org/10.7289/V54Q7S16).

<p>Desde o período das Grandes Navegações, mais precisamente nos séculos XV e XVI, procura-se uma maneira mais rápida de ligar a Europa, Ásia e América. Nessa procura muitos exploradores se aventuraram no Ártico, porém naquela época, as condições climáticas eram diferentes das atuais, sendo que o gelo marinho cobria quase toda extensão do Oceano Ártico mesmo no verão.  Assim, as rotas marítimas árticas não puderam ser exploradas por muito tempo. Entretanto, com o atual aquecimento no Ártico e a consequente retração do gelo marinho, o que era um sonho passa a ser realidade: as rotas que outrora foram abandonadas por serem de difícil acesso, passam a ligar o mundo de maneira mais rápida e barata. Neste artigo examina a procura por essas rotas em artigos científicos e em livros que relatam registros históricos e qual é a expectativa para o século XXI.</p><p><strong>Palavras–chave:</strong> Rota Nordeste, Rota Noroeste, Ártico.</p><p><strong>Abstract </strong></p><p>Since the Great Navigations period, 15th and 16th centuries, there has been a search for faster sea-lanes to connect Europe, Asia and America.

ABSTRACT As the Arctic becomes more heavily populated and more open to commercial shipping operations, the threat of an oil spill increases. On the Grand Banks of Newfoundland, both fixed and mobile oil rigs drill for the region's highly lucrative natural oil resources. This region also happens to be one of the most dangerous shipping areas in the world. The cold Labrador Current travels south from the Arctic bringing with it icebergs calved from the glaciers along the Western Greenland coast. As these icebergs travel south, they intersect directly with the transatlantic shipping lanes following the Great Circle route just south of Cape Race, Newfoundland. The cold waters of the Labrador Current interact with the warm waters of the Gulf Stream to create extensive regions of fog with little to no visibility. As the Arctic Ocean becomes more accessible to shipping, vessels will not only transit this region travelling east and west, but also north and south to new production areas in the Arctic. Any vessel entering or exiting the Northwest Passage must transit through this region. An oil spill caused by an explosion on one of the Grand Banks' oil rigs, an allision of an iceberg with one of the rigs, or a collision of a commercial tank vessel with an iceberg are just a few of the possible scenarios that could cause a devastating incident in this region. Pervasive fog limiting aerial and satellite coverage, the diverse seabird, fish, and marine mammal population, and the presence of sea ice and icebergs during more than half of the year would result in one of the most challenging responses in the world. Transport Canada, the Canadian Coast Guard, and the Canadian Association of Petroleum Producers have conducted extensive preparations for an oil spill response in this region. However, a more far-reaching response plan must be created through consultation between government and industry stakeholders, using lessons learned from the Deepwater Horizon incident in the Gulf of Mexico to prepare for an internationally-significant event. With the opening of the Arctic Ocean and the increase in the shipping and offshore drilling in this area, a comprehensive plan must be developed before an internationally-significant oil spill occurs.

The sky is a blinding white and blue, and the little minibus from Listvianka to Irkutsk flits over the folds of the Angara Valley like a bumblebee, slightly ungainly and, to an observer, perhaps not quite in control of its trajectory, but confident in its own path and in the completion of its journey. We’ve seen our last of Baikal. One last run alongside daughter Angara and James and I will get our final glimpse of the lake’s cobalt water, bearing northwest for the turbines and factories of the Angarsk industrial corridor and then, slightly tarnished, on to her rendezvous with her beloved Yenisei and finally the Arctic ocean, 2,500 river kilometers downstream. One last pass through Irkutsk, and we’ll be back on the beast-machine bound for Moscow and beyond, and a world more familiar if still not known. We’ve seen our last of Baikal, but I’m pretty sure that I, anyway, am not leaving it behind, that it will never quite stop flowing through me. Blood has the same salinity as the ocean, someone once told me—we never really left the sea, we just carry it around inside us. Alas, this little detail of life turns out to be just too exquisite to be true, but it sure works as metaphor—we all carry around a biological memory of where and what we come from, from the water that makes up roughly sixty percent of our bodies to the ninety-eight or so percent of our genes that we share with chimpanzees. And so it is with Baikal—the lake inseparable from the people who love it in so many complex and ambiguous ways—I’ll carry a piece of it around in every part of me, like a new strand of DNA that has spliced itself in with mine and changed ever so slightly who I am and how I live in the world. For our last couple of nights back in Irkutsk, James and I stay in a downtown hotel, for about three times the cost of the American House, where, Olga tells us, we can finally get our visas properly registered.

Abstract. The World Ocean Database (WOD) contains over 1.3 million oceanographic casts (where cast refers to an oceanographic profile or set of profiles collected concurrently at more than one depth between the ocean surface and ocean bottom) collected in the Arctic Ocean basin and its surrounding marginal seas. The data, collected from 1849 to the present, come from many submitters and countries, and were collected using a variety of instruments and platforms. These data, along with the derived products World Ocean Atlas (WOA) and the Arctic Regional Climatologies, are exceptionally useful – the data are presented in a standardized, easy to use format and include metadata and quality control information. Collecting data in the Arctic Ocean is challenging, and coverage in space and time ranges from excellent to nearly non-existent. WOD continues to compile a comprehensive collection of Arctic Ocean profile data, ideal for oceanographic, environmental and climatic analyses (https://doi.org/10.7289/V54Q7S16).
