Airborne electromagnetic estimation of groundwater quality and distribution in the top 100m of the earth. This research will develop processing methodology to predict groundwater concentration and quality in the top 100m of the earth, using continuously sampled airborne electromagnetic data. The method to be developed will process received responses to separate and identify propagation delays, distinct from the usual diffusive delays caused by shallow conductive materials. The extracted propagation delays then predict ground moisture content. With proposed changes to transmitter hardware, we can also achieve improved shallow resolution of conductive structures, such as shallow saline groundwater layers. However, the new method will pioneer the remote detection of fresh waters.

地下水质量和分布的航空电磁估计在地球顶部100米。这项研究将开发处理方法，预测地下水浓度和质量在地球的顶部100米，使用连续采样的航空电磁数据。待开发的方法将处理接收到的响应，以分离和识别传播延迟，不同于由浅导电材料引起的通常的扩散延迟。提取的传播延迟，然后预测地面水分含量。通过对发射机硬件的拟议更改，我们还可以提高导电结构（例如浅层咸水地下水层）的浅层分辨率。然而，新方法将开创远程探测淡水沃茨的先河。
