Abstract

The paper presents results of investigations of bottom sediments in Hornsund, Wijdefjorden and Isfjorden as well as of the shelf around the Bjornoya. carried out in 1982—1985 by a continuous seismic profiling. Geophysic structures and bottom sediments on the bedrock to a depth of 170 ms have been recognized, particularly in the Hornsund region. The following seismoacoustic units have been distinguished: unit A — bedrock, unit В — till and/or compacted glaciogenic deposit, unit С — glaciomarine ice-front deposit, unit D — glaciomarine mud. These results allowed to present a model of glaciomarine sedimentation in a fiord, fed by warm tidewater glaciers.
