Project EASTMAR: acquisition of high sensitivity aeromagnetic data off East Greenland

Abstract

Project EASTMAR, an aeromagnetic survey of major parts of the continental margin off East Greenland, is an energy research project originally funded by the Danish government through the Energy Agency (Thorning, 1978; Larsen & Thorning, 1979). During 1979, the EASTMAR project has been included in an EEC supported geophysical project called the NAD project (North Atlantic D; see also Risum, this volume). The aim of the NAD project is to map the deep and regional structures of the continental margin off East Greenland by using high sensitivity aeromagnetic surveys, multichannel seismic reflection and marine gravity surveys, and to prepare a preIiminary assessment of the petroleum geology of the region. In 1979, the main work of EASTMAR has been the acquisition of new aeromagnetic data between latitudes 600 N and 800 N in accordance with the flight programme (fig. 31; and Larsen & Thorning, 1979) and compilation of existing aeromagnetic and seismic data (Larsen, 1980).
