description |
Long-range airborne geophysical measurements were carried out in the ICEGRAV campaigns (2010-2013), covering hitherto unexplored parts of interior East Antarctica and part of the Antarctic Peninsula. The airborne surveys provided a regional coverage of gravity, magnetic and ice-penetrating radar measurements for major Dronning Maud Land ice stream systems, from the grounding lines up to the Recovery Lakes drainage basin, and filled in major data voids in Antarctic data compilations.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. : The dataset available here includes all channels from raw through to levelled and microlevelled products. Channel naming and processing 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 (nT). Adjustments to compensate for aircraft roll, pitch and yaw were applied. 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 2010 as implemented in Geosoft (nT). MagRTC- Compensated magnetic value adjusted for Tip tanks (where used) and geomagnetic reference field values. MagRTC= MagR- RefField (nT). BCorr_FD83- Low pass filtered (60 minute) magnetic base station (located at camp FD83) correction. BCorr_Halley- Low pass filtered (60 minute) magnetic base station (located at Halley) correction. BCorr_Applied- Which of the two base station correction values were applied. 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. Basic channel description: 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 Weddell Lambert with two standard parallels defined as follows: Latitude of false origin: -80 Longitude of false origin: -81 Latitude of 1st standard parallel -82 Latitude of 2nd standard parallel -78 False easting 26501 False northing 1977093 : No values are given for Scorr. |
