Earthsound have a range of handheld and cart-mounted, gridded and RTK GPS-acquired systems which allow for the rapid mapping of magnetic anomalies within the sub-soil, producing a magnetic map of the underlying archaeology. Archaeological features such as kilns, furnaces, hearths and burnt mounds of stone create strong magnetic anomalies from burning and heating processes; other features such as infilled pits and ditches gain a natural magnetism over time which can also be detected across most soils.<\/p>\n<p><a href=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2015\/10\/DSC_5877.jpg\" target=\"_blank\" rel=\"noopener noreferrer\"><img loading=\"lazy\" class=\"wp-image-821 alignnone\" src=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2015\/10\/DSC_5877.jpg\" alt=\"\" width=\"660\" height=\"410\" \/><\/a><\/p>\n<div id=\"attachment_1871\" style=\"width: 296px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCdata.jpg\" target=\"_blank\" rel=\"noopener noreferrer\"><img aria-describedby=\"caption-attachment-1871\" loading=\"lazy\" class=\"wp-image-1871\" src=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCdata-300x215.jpg\" alt=\"\" width=\"286\" height=\"204\" srcset=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCdata-300x215.jpg 300w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCdata-768x550.jpg 768w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCdata-618x442.jpg 618w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCdata-444x318.jpg 444w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCdata.jpg 1020w\" sizes=\"(max-width: 286px) 100vw, 286px\" \/><\/a><p id=\"caption-attachment-1871\" class=\"wp-caption-text\">Example of Magnetometer survey results.<\/p><\/div>\n<div id=\"attachment_1872\" style=\"width: 307px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCinterp.jpg\" target=\"_blank\" rel=\"noopener noreferrer\"><img aria-describedby=\"caption-attachment-1872\" loading=\"lazy\" class=\"wp-image-1872\" src=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCinterp-300x206.jpg\" alt=\"\" width=\"297\" height=\"204\" srcset=\"http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCinterp-300x206.jpg 300w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCinterp-768x526.jpg 768w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCinterp-618x423.jpg 618w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCinterp-444x304.jpg 444w, http:\/\/www.earthsound.ie\/wp-content\/uploads\/2017\/08\/GCinterp.jpg 1016w\" sizes=\"(max-width: 297px) 100vw, 297px\" \/><\/a><p id=\"caption-attachment-1872\" class=\"wp-caption-text\">Interpretation drawing showing features detected by the Magnetometer survey.<\/p><\/div>\n\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>Magnetometer surveys are the most frequently used geophysical technique in Ireland and the UK.
