Earthsound directors Dr. James Bonsall and Heather Gimson flew over to the University of Warsaw this week to participate in the 11th International Conference on Archaeological Prospection.<\/p>\n

Earthsound provided equipment and logistical support for the investigation while Earthsound surveyor Darren Regan assisted James every month for the 14 month long time-lapse earth resistance survey carried out at Tuam, Co. Galway. The investigation examined the impact of weather on the outcomes of earth resistance surveys on behalf of the archaeology section of the National Roads Authority. The paper was live\u00a0tweeted – here are some of the highlights:<\/p>\n\n\nLast but not least, @DrJamesBonsall<\/a> talking about using repetetive time-lapse earth resistance data to optimise survey conditions #ISAP2015<\/a><\/p>\n— Kayt Armstrong (@girlwithtrowel) September 17, 2015<\/a><\/p><\/blockquote>\n<\/div>\n\n\n#ISAP2015<\/a> @DrJamesBonsall<\/a> @resandmag<\/a> headlining today's conference #seasonalityrules<\/a><\/p>\n— Robert Fry (@robfry2000) September 17, 2015<\/a><\/p><\/blockquote>\n<\/div>\n\n\nMoisture contrasts obvs important for earth resistance surveys. 2nd most used technique in Irish archaeology #ISAP2015<\/a><\/p>\n— Kayt Armstrong (@girlwithtrowel) September 17, 2015<\/a><\/p><\/blockquote>\n<\/div>\n\n\nDeveloper led survey: you can't chose when you work.
