Processed line aeromagnetic data over the Jutulstraumen rift area (2001/02 season)
GB/NERC/BAS/PDC/01275

Summary

Abstract:
A British Antarctic Survey Twin Otter and survey team acquired 15,500 line-km of aeromagnetic data during the 2001/02 Antarctic field season along a 1-km line spacing grid with tie-lines 8 km apart. Twenty-five flights were flown from the South African base SANAE, for a total of 100 survey hours. We present here the processedline aeromagnetic data acquired using scintrex cesium magnetometers mounted on the BAS aerogeophysically equipped Twin Otter.The aeromagnetic data were acquired at a constant barometric altitude of 2600 m.This provided a terrain clearance of 100 m over the highest peaks. The choice of a barometric survey mode was acompromise for the acquisition of reliable aerogravity data.
Data are provided as XYZ ASCII line data. This high-resolution aerogeophysical survey was part of the "Magmatism as a Monitor of Gondwanabreak-up" project (MAMOG) of the British Antarctic Survey, which included new geochemical investigations, structural geology, geochronology, and AMS studies over western Dronning Maud Land.
