It is often used to identify areas of interest to develop a detailed geophysical strategy. Magnetic Susceptibility surveys can also be used within excavation areas, mapping individual features, divisions or zones. Earthsound often supplement other survey techniques, such\u00a0 as magnetometer investigations, with Magnetic Susceptibility surveys. Magnetic Susceptibility usefully indicates the ability of a soil to become magnetised, which has implications for the success or otherwise of a magnetometer survey and is influenced by environmental, geological, agricultural and archaeological sources. Soils are assessed in the field using a hand-held device placed upon the ground surface; its susceptibility to a temporary magnetic field is recorded using a GPS, creating a digital basemap of potential archaeological activity.<\/p>\n<div id=\"attachment_2100\" style=\"width: 292px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2019\/02\/MS-317-a.jpg\"><img aria-describedby=\"caption-attachment-2100\" loading=\"lazy\" class=\"wp-image-2100\" src=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2019\/02\/MS-317-a-973x1024.jpg\" alt=\"\" width=\"282\" height=\"297\" srcset=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2019\/02\/MS-317-a-973x1024.jpg 973w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2019\/02\/MS-317-a-285x300.jpg 285w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2019\/02\/MS-317-a-768x808.jpg 768w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2019\/02\/MS-317-a-618x651.jpg 618w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2019\/02\/MS-317-a-422x444.jpg 422w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2019\/02\/MS-317-a.jpg 1158w\" sizes=\"(max-width: 282px) 100vw, 282px\" \/><\/a><p id=\"caption-attachment-2100\" class=\"wp-caption-text\">A wintery Magnetic Susceptibility survey being carried out<\/p><\/div>\n<div id=\"attachment_1194\" style=\"width: 279px\" class=\"wp-caption aligncenter\"><img aria-describedby=\"caption-attachment-1194\" loading=\"lazy\" class=\"wp-image-1194\" src=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/Knocknashee_MS_SR.jpg\" alt=\"\" width=\"269\" height=\"381\" \/><p id=\"caption-attachment-1194\" class=\"wp-caption-text\">An example of data acquired from a Magnetic Susceptibility survey<\/p><\/div>\n<p style=\"text-align: center;\"><span style=\"color: #003366;\">&copy; 2002- 2026 Earthsound Geophysics Ltd.<\/span><\/p>\n<p><img loading=\"lazy\" class=\"aligncenter size-full wp-image-1000\" src=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/EAG_header_alt_old.jpg\" alt=\"\" width=\"1260\" height=\"240\" \/><\/p>\n\n<div class=\"twitter-share\"><a href=\"https:\/\/twitter.com\/intent\/tweet?via=EAG_Earthsound\" class=\"twitter-share-button\">Tweet<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Magnetic Susceptibility is a rapid reconnaissance technique that can provide a broad assessment of large sites.
