Best practices for using electrical resistivity tomography to investigate permafrost<\/strong><\/h2>\n\n\n\n

Une \u00e9tude r\u00e9cente de Teddi Herring<\/a> sugg\u00e8re des moyens d'am\u00e9liorer la fa\u00e7on dont la tomographie par r\u00e9sistivit\u00e9 \u00e9lectrique (Electrical Resistivity Tomography ou ERT) est utilis\u00e9e pour le perg\u00e9lisol et met en \u00e9vidence les progr\u00e8s r\u00e9cents dans cette approche. L'ERT est une technique extr\u00eamement utile pour \u00e9tudier le perg\u00e9lisol, car elle nous permet de conna\u00eetre la profondeur de la couche de perg\u00e9lisol et d'identifier les zones contenant de la glace.<\/p>\n\n\n\n

Le nombre de publications d'\u00e9tudes utilisant l'ERT pour analyser le perg\u00e9lisol a \u00e9t\u00e9 multipli\u00e9 par 10 au cours des 20 derni\u00e8res ann\u00e9es, et bien que des d\u00e9fis demeurent et qu'il n'existe pas encore de \u00ab meilleure fa\u00e7on \u00bb unique de le faire, l'\u00e9tude formule des recommandations pour mener des \u00e9tudes ERT afin de maximiser l\u2019utilit\u00e9 des donn\u00e9es existantes et futures.<\/p>\n\n\n\n
