AWI-AEROMAG 93-96

The regional aeromagnetic datasets were acquired from the Alfred Wegener Institute for Polar and Marine Research (AWI), Bremerhaven, Germany, in four field campaigns along the coastal regions of Northeast Greenland from 1993-1996. The line spacing ranges both in inline and crossline direction from 10-40 km and the levels range up to 3700 m. Presented maps are based on data reprocessed by GEUS.

Statement: Magnetic maps are based on data acquired and processed in the 90s. The acquisition pattern with sparse and irregular line spacing from 5 to 40 km results into a rather low spatial resolution such the use of these data is mainly limited to regional studies. Data quality is limited since flights were partly acquired in periods with distinct geomagnetic activities and with the larger distances to the next magnetic reference station (stations at Zackenberg, Constable Point and Station Nord were used). However, recent reprocessing (2019) with modern leveling methods has improved the data quality by reducing levelling artefacts.”
