Processed line aeromagnetic data over the Black Coast (1996/97 season)
Using the British Antarctic Survey''s DeHavilland Dash-7, approximately 10,000 line-km of data were collected from the Black Coast and adjacent Weddell Sea embayment, which is situated ca. 600 km southeast of the airfield at Rothera Station . Flight lines were spaced at 10-km intervals with perpendicular tie lines spaced at 40 km. Where time and fuel allowed, selected areas were infilled at a 5-km line spacing. The marine part of the survey was flown at around less than 1000 m above sea level.We present here the processed line aeromagnetic data acquired using scintrex cesium magnetometers mounted on the BAS aerogeophysical equiped Dash-7.
Data are provided as XYZ ASCII line data.

Survey flights were restricted to times when a minimum of five satellites could be recorded both on the aircraft and at the ground station. The relative Dilution of Precision (RDOP) never rose above 5.0. Post-flight continuous kinematic differential GPS processing was carried out using Trimble GPSurvey software. RMS errors were ca. 0.08 m and the absolute positional accuracy is thought to be better than 5 m.
Caesium-vapour magnetometers have a sensitivity of 0.005 nT, but the Dash-7 serves a dominantly logistic role, and so, it cannot provide the same data quality as a dedicated aeromagnetic survey plane. As a result, fourth digital differences (a commonly used figure of merit) for a typical uncompensated flight line are within 1.5 nT and this value drops to below 1 nT after compensation.
No values are given for MagC, TCorr, MagRTC, BCorr, MagBRTC and SCorr. These channels are included for compatibility with ADMAP2 convention.
