Fitzroy and Margaret rivers spatial mapping of radon and helium-4 in surface water

This data set contains shape files representing the locations and results of radon(222Rn) and helium-4(4He) surface water sampling from in-stream reaches and pools, as well as off-channel wetlands of the Fitzroy and Margaret rivers Western Australia. The data provides information about the spatial nature of connectivity between groundwater and surface water along approximately 300 km of the Fitzroy River and 80 km of the Margaret River. The data was collected via helicopter in June 2017. The purpose of the data set is to graphically communicate the results of 222Rn and 4He sampling in surface water and how that relates to spatial changes in groundwater – surface water connectivity.

本数据集包含形状文件（shape files），用于表征澳大利亚西部菲茨罗伊河与玛格丽特河的河道内河段、塘池以及河道外湿地的地表水中氡（radon, ²²²Rn）与氦-4（helium-4, ⁴He）的采样点位及检测结果。该数据集提供了沿菲茨罗伊河约300公里、玛格丽特河约80公里河段的地下水与地表水之间连通性的空间特征信息。数据采集工作于2017年6月通过直升机完成。本数据集旨在可视化呈现地表水中氡-222与氦-4的采样结果，以及该结果与地下水-地表水连通性的空间变化之间的关联。
