Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) - Western Australia data release (till Feb 2024)

Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to a low emissions economy, strong resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight-year, $225m investment by the Australian Government.The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) is a collaborative national survey that acquires long-period magnetotelluric (MT) data on a half-degree grid spacing across Australia. This national scale survey aims to map the electrical conductivity/resistivity structure in the crust and mantle beneath the Australian continent, which provides significant additional information about Australia’s geodynamic framework as well as valuable pre-competitive data for resource exploration. As part of the Exploring for the Future Program, Geoscience Australia has completed AusLAMP data acquisition at 32 sites across the southwest and southeast region of Western Australia. The data were acquired using LEMI-424 instruments and were processed using the LEMI robust remote referencing process code. This data release contains acquired time series data and processed data at each site. The time series data are in original format (.txt) recorded by the data logger and in MTH5 hierarchical format. The open-source MTH5 Python package (https://github.com/kujaku11/mth5) was used to convert the recorded data into MTH5 format. The processed data are in Electrical Data Interchange (EDI) format.  We acknowledge the Geological Survey of Western Australia for assistance with field logistics and land access, traditional landowners, private landholders and national park authorities within the survey region, without whose cooperation these data could not have been collected.Time series data is available on request from [e-mail] - Quote eCat# 149416.

澳大利亚地球科学局（Geoscience Australia）的"未来探索计划"（Exploring for the Future）可为政府、社会各界及行业开展澳大利亚矿产、能源与地下水资源可持续开发的决策提供科学支撑。该计划通过收集、分析、解读新获取及已有的预竞争性地球科学数据与知识，构建澳大利亚地质与资源潜力的全国性全貌，最终助力打造强劲的经济、韧性的社会与可持续的环境，惠及全体澳大利亚民众，其中包括支撑澳大利亚向低碳经济转型、巩固资源与农业产业，以及为澳大利亚区域及偏远社区创造经济机遇与社会福祉。该计划于2016年启动，是澳大利亚政府为期8年、投资额达2.25亿澳元的投资项目。

澳大利亚岩石圈结构大地电磁项目（Australian Lithospheric Architecture Magnetotelluric Project, AusLAMP）是一项全国性合作调查项目，将以半度网格间距在澳大利亚全境采集长周期大地电磁（magnetotelluric, MT）数据。此项全国性调查旨在绘制澳大利亚大陆下方地壳与地幔的电导率/电阻率结构，可为澳大利亚地球动力学框架研究提供重要补充信息，同时为资源勘探提供极具价值的预竞争性数据。

作为"未来探索计划"的组成部分，澳大利亚地球科学局已在西澳大利亚州西南与东南区域的32个测点完成AusLAMP的数据采集工作。本次数据采集使用LEMI-424仪器，并通过LEMI稳健远程参考处理代码完成数据处理。本次发布的数据包含各测点的原始时序数据与处理后数据：时序数据包括数据记录仪记录的原始格式（.txt）文件，以及MTH5层级格式文件，本次格式转换使用开源Python工具包MTH5（https://github.com/kujaku11/mth5）完成；处理后数据采用电子数据交换（Electrical Data Interchange, EDI）格式。

我们谨向西澳大利亚州地质调查局致以谢意，感谢其在野外后勤保障与土地准入方面提供的协助；同时感谢调查区域内的传统土地所有者、私人土地持有者与国家公园管理部门，若无各方的配合与支持，本次数据采集工作无法顺利完成。
