Circum-Arctic Mapping Project - Gravity and magnetic maps (CAMP - GM)
An international effort to compile Circum-Arctic geophysical and bedrock data has been conducted by several national agencies (Russia, Sweden, Finland, Denmark, USA, Canada, Germany and Norway). This project produced an atlas that comprise geological and geophysical digital maps at a scale of 1: 5 m...
