Barrow Dampier Offshore Magnetic Line Data

Total magnetic intensity data measures variations in the intensity of the Earth's magnetic filed caused by the contrasting content of rock-forming minerals in the Earth's crust. The data are collected on airborne geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.

总磁强度数据（Total magnetic intensity data）用于测量地球磁场（Earth's magnetic field）强度的变化，这种变化由地壳（Earth's crust）中造岩矿物（rock-forming minerals）的含量差异所致。该数据通过联邦政府（Commonwealth）、州及北领地政府（State & NT Governments）与私营部门（private sector）开展的航空地球物理测量（airborne geophysical surveys）收集获得。
