Røst Basin Aeromagnetic Survey (RAS-03). ra 3 aeromagnetic compilation. Data acquisition and processing report

A high sensitivity aeromagnetic survey (RAS-03) was carried out in an area of c. 41400 km2 over the Røst Basin offshore Lofoten, Northern Norway. Data processing comprised spike removal and data editing, IGRF correction, loop closure levelling and floating differential median micro-levelling. Four m...
