The geological implications of the upper seismic unit, southeastern Barents Sea

Abstract

An upper Quaternary seismic unit has been mapped to the east and southeast of Bjern~yrennain the Barents Sea. The unit is dcfined by interpretation of shallow seismic (sparker) data, and occurs as an upper, seismically transparent sequence in the Quaternary succcssion. Discontinuous internal reflections do, however, occasionally occur, especially in the lower part of the unit. The sediments in the unit are interpreted to be of a glaciogenic origin and they most likely consist mainly of tlll.
