Bathymetry and physiography
Published:January 01, 1990
The oceanic regions located north of the Arctic Circle are the Arctic Ocean, the Norwegian-Greenland Sea, and Baffin Bay (Plate 1). The latter is described in Keen and Williams (1990). Despite the bold isobaths in Plate 1, the bathymetry of the Arctic Ocean is still poorly known. Most of the Norwegian-Greenland Sea, on the other hand, is quite precisely charted. Exceptions are the areas east of Greenland often covered by the pack ice that exits the Arctic Ocean in the East Greenland current.
The names used for the physiographic features in this volume are those shown on Plate 1....

The Arctic Ocean Region
Most Quaternary sediments in North America north of 45 ON post-date the last deglaciation. This volume looks at those extensive deposits from the standpoints of timing, cause, and mechanism of the wastage of North American ice during the last deglaciation and the accompanying environmental changes in the nonglaciated and deglaciated areas. It particularly examines the mechanisms by which a mass of ice equivalent to 100 m of global sea-level was returned to the ocean within about 8,000 years. A truly comprehensive synthesis of marine and terrestrial information in 22 chapters grouped into five sections: Chronology of Disintegration of the North American Ice Sheets, Ice Core and Other Glaciological Data, the Nonglacial Physical Record on the Continent, Biological Record on the Continent, and Analysis and Summary. Includes two oversize color plates showing time-series maps of pollen densities and vegetation changes since 18 ka.
