| Abstract |
The modern depositional environment of the deep Norwegian-Greenland Sea is highly asymmetric in an E-W direction because of the hydrography of the surface water masses and because of the more or less permanent pack ice cover of the East Greenland Current regime along the Greenland continental margin. By means of sedimentation rates the authors have tried to investigate whether this hydrographic asymmetry influenced the sediment input to the Norwegian-Greenland Sea over the past 60 m.y. Sediment input can be quantified if thicknesses of sediment sections accumulated over known time intervals can be measured and if some of their physical properties have been determined. Sedimentation rates have been estimated for Tertiary and Quaternary times, and their temporal as well as their spatial changes are discussed. |
