Aeromagnetic data are presented in Jordan et al. (2014) and datasets available here include all channels from raw through to levelled, and microlevelled products. Channel naming follows SCAR/ADMAP2 data release protocols. It should be noted that in the Fuchs magnetic database, channels are sorted by x coordinates ascending. Note in the database split by line the sections are defined as follows L= main survey grid lines, T=main survey tie lines. Magnetic data channels and processing flow for HRAM low and high cap surveys: MagR- Raw magnetic total field intensity data (nT). MagC- Compensated, or low pass filtered magnetic data (nT). 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. TCorr- Manual corrections made to account for tip tank events, data spikes etc. RefField- Geomagnetic reference field value for which the magnetic data has been compensated. IGRF model 2010 as implemented in Geosoft (nT). MagRTC- Compensated magnetic value adjusted for Tip tanks (where used) and geomagnetic reference field values (nT). MagRTC= MagR- RefField. BCorr- Low pass filtered (60 minute) magnetic base station correction (nT). MagBRTC- calculated as MagBRTC= MagRTC- Bcorr (nT). ACorr- Additional correction applied to compensate for heading errors. MagF- Final mag value before levelling (nT). MagL- Statistically levelled mag data (nT). MagML- Microlevelled magnetic data following technique of (Ferraccioli et al., 1998) (nT). Note tie lines are not included in the microlevelled data channel. Magnetic data channels and processing flow for Fuchs survey: MagR- Raw magnetic total field intensity data (nT). TCorr- Manual corrections made to account for tip tank events, data spikes etc. RefField- Geomagnetic reference field value for which the magnetic data has been compensated. IGRF model 2010 as implemented in Geosoft (nT). MagRT- Compensated magnetic value adjusted for Tip tanks (where used) and geomagnetic reference field values. (nT) MagRTC= MagR- RefField. BCorr- Low pass filtered (60 minute) magnetic base station correction. MagBRT- calculated as MagBRT= MagRT- Bcorr (nT). ACorr- Additional correction applied to compensate for low amplitude, high frequency remnant noise in the data. A high-pass filter with a cutoff wavelength of 15 fiducials was used. MagF- Final mag value before levelling (nT). MagL- Statistically levelled mag data (nT). MagML- Microlevelled magnetic data following technique of (Ferraccioli et al., 1998) (nT). Note tie lines are not included in the microlevelled data channel.
