Satellite magnetic field over the Nares Strait region
The general characteristics of the total field magnetic anomalies from satellite data over the region adjacent to Nares Strait are briefly described. The interpretation of satellite data is still at an early stage, but it is favoured that the regional anomalies in this region reflect variations in c...
