The Lower Loup and Middle Republican Nebraska Natural Resources Districts (NRDs) conducted AEM flights in Summer 2022 using Water Sustainability Fund (WSF) grant dollars awarded in 2021.  In eastern Nebraska, a private entity in the Lower Platte South NRD also conducted an AEM reconnaissance survey in Cass County Nebraska in 2022 as a follow-up to the previous 2020 AEM Cass County survey.  

Approximately 133 line-miles of AEM survey were acquired with the SkyTEM 304-HR75 system for the Cass County 2022 AEM survey.  Collected data was processed in the Spatially Constrained Inversion (SCI) AEM earth models with 39 layers.  In addition to covering a larger area, the 2022 survey lines were tighter in pattern as compared to the 2020 Cass County AEM survey lines conducted with the SkyTEM304M system.
