Central North Sea Aeromagnetic Survey 2010 (CNAS-10) data acquisition and processing

A regional aeromagnetic survey has been carried out in the North Sea called the Central North Sea Aeromagnetic Survey 2010 (CNAS-10). The acquisition was carried out during the period 26 May – 12 October 2010. The airborne magnetic survey was conducted with constant flight-line orientations. In-lines were running E-W-oriented with perpendicular tie-lines N-S (c. -6° off geogr. N). Line spacing was set to 1 km for the profiles and 4 km for the tie lines to achieve a good control on the diurnal variations of the magnetic field during the data processing.
