Abstract

On 24th May 1979 the Council of the European Communities adopted its regulation No 1038/79 on Community support for a hydrocarbon exploration project in Greenland - Project NAD. This project is an integrated aeromagnetic and marine geophysical project off the east coast of Greenland. Part 1 is the aeromagnetic programme - Project EASTMAR Larsen & Thorning, this report); part 2 is the marine geophysical programme. The aim of this project is to map the continental margin of East Greenland, using high sensitivity aeromagnetic surveys and multichannel seismic refiection and marine gravity surveys, and to prepare a preliminary petroleum geological assessment of the region.

Highlights

  • Based on the evidence of both aeromagnetic and marine geophysical work done by various research organisations, sedimentary basins are known to exist offshore East Greenland (Larsen & Thorning, 1979; Larsen, this report)

  • One of the previous surveys employed a multi-coverage seismic survey of a quality sufficiently high for this evaluation (Hinz & Schliiter, 1978). From this survey only a few lines are available on the East Greenland shelf and a more closely spaced grid is needed

  • The data acquisition programme will consist of 48-fold refiection seismic recording, marine gravity and magnetic recording, and sonobuoy refraction measurements

Summary

Background

Based on the evidence of both aeromagnetic and marine geophysical work done by various research organisations, sedimentary basins are known to exist offshore East Greenland (Larsen & Thorning, 1979; Larsen, this report). The data available from these investigations are of a rather varied quality. The new project EASTMAR data will be a most valuable contribution to a detailed delineation of the sedimentary basins. One of the previous surveys employed a multi-coverage seismic survey of a quality sufficiently high for this evaluation (Hinz & Schliiter, 1978). From this survey only a few lines are available on the East Greenland shelf and a more closely spaced grid is needed. It is hoped that the project NAD - Part 2 will provide this
