Palynological Investigations of Miocene Deposits on the New Siberian Archipelago (U.S.S.R.)
ARCTIC VOL. 45, NO.3 (SEPTEMBER 1992) P. 285-294 Palynological Investigationsof Miocene Deposits on the New Siberian Archipelago(U.S.S.R.)’ EUGENE v. ZYRYANOV~ (Received 12 February 1990; accepted in revised form23 January 1992) ABSTRACT. New paleobotanical data (mainly palynological) are reported from Miocene beds of the New Siberian Islands. The palynoflora has a number of distinctive features: the presence of typical hypoarctic forms, the high content taxa representing dark coniferous assemblages and the con- siderable proportion of small-leaved forms. Floristic comparison with the paleofloras of the Beaufort Formation in arctic Canada allows interpreta- tion of the evolution of the Arctic as a landscape region during Miocene-Pliocene time. This paper is a preliminary analysis of the mechanisms of arctic florogenesis. The model of an “adaptive landscape” is considered in relation to the active eustaticdrying of polar shelves. Key words: palynology, U.S.S.R., NewSiberian Islands, Miocene,Arctic, florogenesis RÉSUMÉ. On rapporte de nouvelles données paléobotaniques (principalement palynologiques) venant de couches datant du miocène situées dans l’archipel de la Nouvelle-Sibérie. La palynoflore possède un nombre de caractéristiques particulières, parmi lesquelles, la présence de formes hypoarctiques typiques, la grande quantité de taxons représentant des assemblages de conifires sombres, ainsi qu’une collection considérable de formes à petites feuilles. Une comparaison floristique avec les paléoflores de la formationde Beaufort dans l’Arctique canadien permet d’interpréter I’évolution de l’Arctique en tant que zone peuplée d’espèces végetales durant le miocbne et le pliocène. Cet article est une analyse préliminaire des mécanismes de la genèse de la flore arctique.

Over a decade (2003-2015) of satellite data of sea-ice extent, sea surface temperature (SST), and methane 11 (CH4) concentrations in lower troposphere over 10 focus areas within the Barents and Kara Seas (BKS) were 12 analyzed for anomalies and trends relative to the Barents Sea. Large positive CH4 anomalies were discovered around 13 Franz Josef Land (FJL) and offshore west Novaya Zemlya in early fall. Far smaller CH4 enhancement was found 14 around Svalbard, downstream and north of known seabed seepage. SST increased in all focus areas at rates from 15 0.0018 to 0.15 °C yr-1, CH4 growth spanned 3.06 to 3.49 ppb yr-1. 16 The strongest SST increase was observed each year in the southeast Barents Sea in June due to strengthening of 17 the warm Murman Current (MC), and in the south Kara Sea in September. The southeast Barents Sea, the south 18 Kara Sea and coastal areas around FJL exhibited the strongest CH4 growth over the observation period.

PETERSBURG 199106, RUSSIA ABSTRACT Plate-tectonic models for the Paleozoic evolution of the Arctic are numerous and diverse. Our detrital zircon provenance study of Upper Paleozoic sandstones from Kotel’ny Island (New Siberian Island archipelago) provides new data on the provenance of clastic sediments and crustal affinity of the New Siberian Islands. Upper Devonian–Lower Carboniferous deposits yield detrital zircon populations that are consistent with the age of magmatic and metamorphic rocks within the Grenvillian-Sveconorwegian, Timanian, and Caledonian orogenic belts, but not with the Siberian craton. The Kolmogorov-Smirnov test reveals a strong similarity between detrital zircon populations within Devonian–Permian clastics of the New Siberian Islands, Wrangel Island (and possibly Chukotka), and the Severnaya Zemlya Archipelago. These results suggest that the New Siberian Islands, along with Wrangel Island and the Severnaya Zemlya Archipelago, were located along the northern margin of Laurentia-Baltica in the Late Devonian–Mississippian and possibly made up a single tectonic block. Detrital zircon populations from the Permian clastics record a dramatic shift to a Uralian provenance. The data and results presented here provide vital information to aid Paleozoic tectonic reconstructions of the Arctic region prior to opening of the Mesozoic oceanic basins.

Ice sheets extending over parts of the East Siberian continental shelf have been proposed during the last glacial period, and during the larger Pleistocene glaciations. The sparse data available over this sector of the Arctic Ocean has left the timing, extent and even existence of these ice sheets largely unresolved.

THE PAST CLIMATE OF THE NORTH POLAR REGION 1 By EDWARD W. BERRY THE JOHNS HOPKINS UNIVERSITY The plants, coal beds, hairy mammoth and woolly rhinoceros ; the corals, ammonites and the host of other marine organisms, chiefly invertebrate but including ichthyosaurs and other saurians, that have been discovered beneath the snow and ice of boreal lands have always made a most powerful appeal to the imagination of explorers and geologists. We forget entirely the modern whales, reindeer, musk ox, polar bear, and abundant Arctic marine life, and remember only the seemingly great contrast between the present and this subjective past. Nowhere on the earth is there such an apparent contrast between the present and geologic climates as in the polar regions and the mental pictures which have been aroused and the theories by means of which it has been sought to explain the fancied conditions of the past are all, at least in large part, highly imaginary. Occasionally a student like Nathorst (1911) has refused to be carried away by his imagination and has called to mind the mar- velously rich life of the present day Arctic seas, but for the most part those who have speculated on former climates have entirely ignored the results of Arctic oceanography.

AN ABSTRACT OF THE THESIS OF MIAH ALLAN BEAL for the Doctor of Philosophy (Name) (Degree) in Oceanography presented on August 12.1968 (Major) (Date) Title:Batymety and_Strictuof_thp..4rctic_Ocean Redacted for Privacy Abstract approved: John V. The history of the explordtion of the Central Arctic Ocean is reviewed.It has been only within the last 15 years that any signifi- cant number of depth-sounding data have been collected.The present study uses seven million echo soundings collected by U. S. Navy nuclear submarines along nearly 40, 000 km of track to construct, for the first time, a reasonably complete picture of the physiography of the basin of the Arctic Ocean.The use of nuclear submarines as under-ice survey ships is discussed. The physiography of the entire Arctic basin and of each of the major features in the basin are described, illustrated and named. The dominant ocean floor features are three mountain ranges, generally paralleling each other and the 40°E. 140°W. meridian. From the Pacific- side of the Arctic basin toward the Atlantic, they are: The Alpha Cordillera; The Lomonosov Ridge; andThe Nansen Cordillera. The Alpha Cordillera is the widest of the three mountain ranges. It abuts the continental slopes off the Canadian Archipelago and off Asia across more than550of longitude on each slope.Its minimum width of about 300 km is located midway between North America and Asia.In cross section, the Alpha Cordillera is a broad arch rising about two km, above the floor of the basin.The arch is marked by volcanoes and regions of "high fractured plateau, and by scarps500to 1000 meters high.The small number of data from seismology, heat flow, magnetics and gravity studies are reviewed.The Alpha Cordillera is interpreted to be an inactive mid-ocean ridge which has undergone some subsidence.
