Magnetic anomaly data over central Marie Byrd Land, West Antarctica (GIMBLE.GMGEO2)
Abstract: GIMBLE was proposed as the first systematic aerogeophysical investigation of the subglacial massif underlying central Marie Byrd Land. Aerogeophysically configured Baslers conducted 14 flights from Byrd Surface Camp and WAIS Divide Camp over two field seasons (January 2013 and December 201...

Level 2 data represent geolocated geophysical properties (e.g ice thickness), derived from Level 1B measurements (e.g. radar echo delay). Dataset structures are based on those used for Operation Ice Bridge, and are line based data in ASCII space delimited .txt files, with a header delimited by leading "#" characters documenting column assignment and metadata. Georefering data is contained in .met files. GIMBLE.GMGEO2 contains line based data (in ASCII space delimited txt files) relating to magnetic anomaly. The raw data was obtained by a tail mounted Geometrics G-823A magnetometer. No heading correction, cross over correction, continuation or base correction have been applied. Data with significant geomagnetic activity (restricted to 07-Dec-2014 and 23-Dec-2014) were removed.
