Processed line aeromagnetic data over Wilkes Subglacial Basin (2005/06 season)
This data set contains aeromagnetic data collected during the WISE/ISODYN project. This collaborative UK/Italian project collected ~ 61000 line km of new aerogeophysical data during the 2005/2006 austral summer, over the previously poorly surveyed Wilkes subglacial basin, Dome C, George V Land and Northern Victoria Land.
We present here the processed line aeromagnetic data collected using scintrex cesium magnetometers mounted on the BAS aerogeophysical equipped Twin Otter.
Data are provided as XYZ ASCII line data.

Methodology:
WISE-ISODYN aeromagnetic data presented in (Ferraccioli et al., 2009), further details on basic data acquisition are described in (Ferraccioli et al., 2007). The dataset available here includes all channels from raw through to levelled, and draped products. Channel naming follows SCAR/ADMAP2 data release protocols
Magnetic data channels and processing flow:
MagR- Raw magnetic total field intensity data (nT).
MagC- Compensated, or low pass filtered magnetic data. Adjustments to compensate for aircraft roll, pitch and yaw were applied (see Ferraccioli et al, 2007 for details). For this survey, both compensation, and low pass filtering of MagR were used.
RefField- Geomagnetic reference field value for which the magnetic data has been compensated. IGRF model 2005 as implemented in Geosoft (nT).
MagRTC- Compensated magnetic value adjusted for Tip tanks (where used) and geomagnetic reference field values. MagRTC= MagR- RefField.
BCorr- Low pass filtered (60 minute) magnetic base station correction.
MagBRTC- calculated as MagBRTC= MagRTC- Bcorr.
ACorr- Additional correction applied to compensate for heading errors.
MagF- Final mag value before levelling.
MagL- Statistically levelled mag data.
MagML- Microlevelled magnetic data following technique of (Ferraccioli et al., 1998). Note tie lines are not included in the microlevelled data channel.
MagML_Drape Microlevelled data draped to a uniform level of 2800m above the bed topography, using the method of (Pilkington and Thurston, 2001).
Basic channel descriptpion:
Line name Line Number
Flight ID Sequential flight number
x x projected meters *
y y projected meters *
Lon Longitude WGS 1984,
Lat Latitude WGS 1984,
Height_WGS1984 Aircraft altitude (meters) in WGS 1984,
Date Date of flight in time format e.g. 2006/01/08
Time Time (UTC) of flight e.g. 23:52:42.0
*Projected coordinates (x and y) are in Lambert conic conformal with two standard parallels defined as follows:
Latitude of false origin: -74.018118
Longitude of false origin: 179
Latitude of 1st standard parallel -72.66666666667
Latitude of 2nd standard parallel -75.33333333333
False easting 1444000
False northing 1123000
Data quality:
No value given for SCorr. This channel is provided for compatibility with ADMAP2 convention.
