Howard East Region, Northern Territory, AEM SkyTEM® airborne electromagnetic data

This package contains airborne electromagnetic (AEM) data from the "SkyTEM helicopter EM Howard East region" survey which was flown over Howard East region, Northern Territory during July - August 2017. The area is comprised of 2073.6 line kilometres in total. The aim of the survey is to provide at a reconnaissance scale: a) trends in regolith thickness and variability b) variations in bedrock conductivity c) conductivity of key bedrock (lithology related) conductive units under cover d) the groundwater resource potential of the region This report lists the SkyTEM system information and specifications relevant for this survey, and describes the processing carried out on the data. Geoscience Australia commissioned the survey as part of the Exploring for the Future (EFTF) program. The EFTF program is led by Geoscience Australia (GA), in collaboration with the Geological Surveys of the Northern Territory, Queensland, South Australia and Western Australia, and is investigating the potential mineral, energy and groundwater resources in northern Australia and South Australia. The EFTF is a four-year $100.5 million investment by the Australian Government in driving the next generation of resource discoveries in northern Australia, boosting economic development across this region (https://www.ga.gov.au/eftf).本数据集包含来自“SkyTEM直升机电磁霍华德东区”勘测的航空电磁（airborne electromagnetic, AEM）数据，该勘测于2017年7月至8月在北领地霍华德东区实施。该勘测区域总测线长度共计2073.6公里。本次勘测旨在以踏勘尺度达成以下目标：a）风化层厚度及其变化趋势；b）基岩电导率的空间变化特征；c）覆盖层下与岩性相关的关键基岩导电单元的电导率；d）该区域的地下水资源潜力。本报告列出了本次勘测相关的SkyTEM系统信息与技术规格，并详述了针对该数据开展的处理流程。澳大利亚地球科学局（Geoscience Australia，简称GA）将本次勘测作为“未来勘探（Exploring for the Future，简称EFTF）”计划的组成部分委托开展。EFTF计划由澳大利亚地球科学局牵头，与北领地、昆士兰州、南澳大利亚州及西澳大利亚州的地质调查机构协作实施，旨在调研澳大利亚北部与南澳大利亚州的矿产、能源及地下资源潜力。EFTF计划是澳大利亚政府为期四年、总投资达1.005亿澳元的项目，旨在推动澳大利亚北部新一代资源勘探发现，助力该区域整体经济发展（详情参见：https://www.ga.gov.au/eftf）。
