Processed line aeromagnetic data over the Institute and Moller region (2010/11 season)
During the 2010/2011 Antarctic field season a collaborative NERC AFI (Antarctic Funding Initiative) project studying the basal boundary conditions of the Institute & Moller ice streams, West Antarctica, collected ~25,000 km of new high quality aeromagnetic data. Data were acquired using scintrex...

description |
During the 2010/2011 Antarctic field season a collaborative NERC AFI (Antarctic Funding Initiative) project studying the basal boundary conditions of the Institute & Moller ice streams, West Antarctica, collected ~25,000 km of new high quality aeromagnetic data. Data were acquired using scintrex cesium magnetometers mounted on the BAS aerogeophysical equiped Twin Otter. Data are provided as XYZ ASCII line data. Data were collected as part of the UK Natural Environment Research Council AFI grant NE/G013071/1. : IMAFI aeromagnetic data and details of survey design and location are presented in (Jordan et al., 2012). The dataset available here includes all channels from raw through to levelled, and draped products. Channel naming follows SCAR/ADMAP2 data release protocols. Key data processing steps are described below. 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. 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- Low pass filtered (60 minute) magnetic base station correction. MagBRTC- calculated as MagBRTC= MagRTC- Bcorr (nT). ACorr- Additional low pass filtering (30 fiducial cutoff) to account for any remnant noise in lines. MagF- Final mag value before levelling. (nT) MagL- Statistically levelled mag data. (nT) MagL_Drape Microlevelled data draped to a uniform level of 2100m above the bed topography, using the method of (Pilkington and Thurston, 2001). (nT) MagML- Microlevelled magnetic data following technique of (Ferraccioli et al., 1998). Note tie lines are not included in the microlevelled data channel. (nT) Basic Channels Line_no 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: -82 Longitude of false origin: -14 Latitude of 1st standard parallel -84 Latitude of 2nd standard parallel -80 False easting 2000000 False northing 2000000 |
