Book Description
The Arctic region has long held a fascination for explorers and scientists of many countries. Despite the numerous voyages of exploration, the na ture of the central Arctic was unknown only 90 years ago; it was believed to be a shallow sea dotted with islands. During Nansen's historic voyage on the polarship Fram, which commenced in 1893, the great depth of the central basin was discovered. In the Soviet Union, investigation of the Arctic Ocean became national policy after 1917. Today research at several scientific institutions there is devoted primarily to the study of the North Polar Ocean and seas. The systematic exploration of the Arctic by the United States com menced in 1951. Research has been conducted year-round from drifting ice islands, which are tabular fragments of glacier ice that break away from ice shelves. Most frequently, ice islands originate off the northern coast of Ellesmere Island. These research platforms are occupied as weather sta tions, as well as for oceanographic and geophysical studies. Several inter national projects, conducted by Canadian, European, and U. S. groups, have been underway during the last three decades. Although much new data have accumulated since the publication of the Marine Geology and Oceanography of the Arctic Seas volume in 1974 (Yvonne Herman, ed. ), in various fields of polar research-including present-day ice cover, hydrogra phy, fauna, flora, and geology-many questions remain to be answered.

Recent Benthic Foraminifera from the Central Arctic Ocean
Author: Martin B. LagoePublisher:
ISBN:
Category : Foraminifera, Fossil
Languages : en
Pages : 478
Book Description
Benthic Foraminifera are present in 97 of 118 samples taken from the central Arctic Ocean. Samples range in depth from 1069 to 3812 meters. Sixty-seven samples contained at least 300 specimens and are termed quantitative samples. The samples were secured from the top three centimeters of sediment cores taken from the Alpha Cordillera, Canada Abyssal Plain and Canada Continental Rise regions of the Arctic Ocean. Seventy-three species of Foraminifera are identified including Triloculina frigida, n. sp.; Chilostomella elongata, n. sp.; and Buliminella elegantissima hensoni, n. var. The fauna is overwhelmingly calcareous and is dominated by the rotaline species Stetsonia horvathi Green, Eponides tumidulus horvathi Green, Eponides tener (Brady) and Epistominella arctica Green.

Book Description
Marine geological and geophysical investigations were carried out in Wellington Channel, Byam Martim and Austin channels, and in eastern Barrow Strait-western Lancaster Sound in 1986, providing information on the distribution, thickness, composition, depositional environments, geotechnical properties, and regional geological setting of the surficial sediments, and on the structure of the near surface bedrock.
Pliocene and Pleistocene Foraminifera Populations in Arctic Ocean Sediment Cores

ISBN:
Category : Foraminifera
Languages : en
Pages : 222
Book Description
The Foraminifera populations and distributions of five deep sea sediment cores recovered from the Arctic Ocean yielded data on 126 species of Foraminifera. Abundance data and species appearance and mortality data across geomagnetic reversal intervals in the cores show no positive correlation. Arctic Ocean Foraminifera apparently do not respond in any significant way to magnetic reversals of the earth's magnetic field. (Modified author abstract).
