Abstract

Abstract Electrical resistivity tomography (ERT) is a minimally invasive geophysical method that produces a model of subsurface resistivity from a large number of electrical resistance measurements. Strong resistivity contrasts usually exist between frozen and unfrozen earth materials, making ERT an effective and increasingly utilized tool in permafrost research. In this paper, we review more than 300 scientific publications dating from 2000 to 2022 to identify the capabilities and limitations of ERT for permafrost applications. The annual publication rate has increased by a factor of 10 over this period, but several unique challenges remain, and best practices for acquiring, processing, and interpreting ERT data in permafrost environments have not been clearly established. In this paper, we make recommendations for ERT surveys of permafrost and highlight recent advances in the field, with the objective of maximizing the utility of existing and future surveys.

使用电阻率层析成像研究永久冻土的最佳实践

电阻率层析成像(ERT)是一种微创地球物理方法，通过大量电阻测量产生地下电阻率模型。冻土和非冻土材料之间通常存在强烈的电阻率差异，这使得ERT成为冻土研究中有效且越来越多地使用的工具。在本文中，我们回顾了2000年至2022年的300多篇科学出版物，以确定ERT在多年冻土应用中的能力和局限性。在此期间，年出版率增加了10倍，但仍然存在一些独特的挑战，并且在永久冻土环境中获取、处理和解释ERT数据的最佳实践尚未明确建立。在本文中，我们提出了冻土ERT调查的建议，并强调了该领域的最新进展，目的是最大限度地发挥现有和未来调查的效用。

期刊介绍： Permafrost and Periglacial Processes is an international journal dedicated to the rapid publication of scientific and technical papers concerned with earth surface cryogenic processes, landforms and sediments present in a variety of (Sub) Arctic, Antarctic and High Mountain environments. It provides an efficient vehicle of communication amongst those with an interest in the cold, non-glacial geosciences. The focus is on (1) original research based on geomorphological, hydrological, sedimentological, geotechnical and engineering aspects of these areas and (2) original research carried out upon relict features where the objective has been to reconstruct the nature of the processes and/or palaeoenvironments which gave rise to these features, as opposed to purely stratigraphical considerations. The journal also publishes short communications, reviews, discussions and book reviews. The high scientific standard, interdisciplinary character and worldwide representation of PPP are maintained by regional editorial support and a rigorous refereeing system.
