The Planning and Execution of Offshore Site Investigations for A North Sea Gravity Platform

AbstractAnalysis of offshore data at scales varing from macroscopic to kilometric suggest the former presence of permafrost in the North Sea. However due to the nature of marine data, the techniques used in recognizing features due to former permafrost differ from that used on land. The evidence can also occur in forms unique to the marine field. Awareness of the former existence of permafrost in the North Sea will aid geological assessment of offshore site investigations.

Sedimentation Processes

AbstractUsing late Quaternary ice marginal sites from the North Sea and Iceland a comparison of the sedimentary information available from subaerial and submarine site investigations was made. This was with regard to palaeo-environmental reconstructions of ice marginal Sedimentation processes. A detailed high resolution seismic survey in-the North Sea was compared to a similar subaerial site in Iceland. Submarine cores were compared with logged sections available from cliffs. These comparisons highlighted the differences in resolution of the structural information available and also the problems of applying existing modeis of glacimarine Sedimentation to offshore sites. This has raised questions concerning the accuracy of reconstructing palaeo-environments and processes in offshore sites presently under investigation. The implications of this for engineering projects in offshore areas requiring very precise site information about relict glaciated areas are significant.
