Book Description
A study of Arctic Ocean sediment cores was undertaken to define the occurrence and relationship of two planktonic Foraminifera, Globigerina pachyderma and Globigerina quinqueloba. The two species were compared morphologically and their abundance peaks were correlated with magnetic stratigraphy as well as with abundance peaks of benthonic Foraminifera. Finally their distribution in the modern oceans was examined as an aid in determining possible changes in the Arctic Ocean of the Late Cenozoic.

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.

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).
