Conductivity meters such as the EM31 are in routine use for mapping shallow salinity, but provide no depth information. This research will provide methodology using broadcast radio transmissions to additionally provide the depth information needed to interpret shallow layering and inhomogeneity. Instruments will initially be tested on the ground, but are ultimately intended to be applied from the air, where existing systems have no resolution in the top 5 m. The method will provide crucial root-zone data for precision agriculture in salt-affected areas, and address accurate salt mapping issues in the major efforts to combat Australia's salinity problems.

EM31等电导率仪通常用于绘制浅层矿化度，但无法提供深度信息。这项研究将提供使用广播无线电传输的方法，以额外提供解释浅层和非均匀性所需的深度信息。仪器最初将在地面上进行测试，但最终打算在空中应用，因为现有的系统在最高5米的范围内没有分辨率。该方法将为受盐影响地区的精准农业提供关键的根区数据，并在解决澳大利亚盐化问题的主要努力中解决精确的盐测绘问题。
