Photo credit: Andreas H\u00f6rdt\/TU Braunschweig<\/p><\/div>\n<p>The palsas are an exciting object of study: mounds within a peat bog that are thought to have a solid ice core and are slowly disintegrating as a result of climate change. The aim of the measurement campaign in Norway was to investigate the structure within the palsas and in the surrounding peatlands. Geophysics allows us to look below the surface without drilling. Electrical methods and georadar are used to produce images of the subsurface, which provide important information about the material composition.<\/p>\n<h3>Unique method of measuring ice content<\/h3>\n<p>In particular, the ice content, which can vary from around 20 per cent to a complete ice core, was the aim of the measurements. The High Frequency Induced Polarisation method was developed at the Institute of Geophysics and Extraterrestrial Physics for this purpose. It is the only method of its kind in the world that has been specifically designed to estimate ice content. Because of its great potential, its application in the Scandinavian peat bogs is funded by the German Research Foundation (DFG).<\/p>\n<div id=\"attachment_65586\" style=\"width: 1510px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65586\" class=\"size-full wp-image-65586\" src=\"https:\/\/magazin.tu-braunschweig.de\/wp-content\/uploads\/2024\/06\/20240518_145813.jpg\" alt=\"\" width=\"1500\" height=\"1000\" \/><p id=\"caption-attachment-65586\" class=\"wp-caption-text\">Heavy equipment had to be carried several 100 metres through the moor or &#8230; Photo credit: Andreas H\u00f6rdt\/TU Braunschweig<\/p><\/div>\n<h3>Hard work in the moor<\/h3>\n<p>Collecting the data also involved some hard work. Heavy equipment had to be carried several hundred metres across the bog, or transported in boats lent by the very helpful local people and the Institute of Geoecology. Occasionally things got a bit adventurous, but apart from the odd soaked gumboots and a stuck car that had to be freed under our own steam, there were no incidents worth mentioning.<\/p>\n<div id=\"attachment_65590\" style=\"width: 1510px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65590\" class=\"size-full wp-image-65590\" src=\"https:\/\/magazin.tu-braunschweig.de\/wp-content\/uploads\/2024\/06\/20240521_122806.jpg\" alt=\"\" width=\"1500\" height=\"1000\" \/><p id=\"caption-attachment-65590\" class=\"wp-caption-text\">&#8230; transported by boat.
