Georadar is a high-tech apparatus used in geophysics, where the image of the internal structure of the soil is displayed using the pulses of radio waves. In other words, radar allows us to see underground. In the peat deposits of the peatlands, the boundary between the peat and the mineral bed is clearly distinguished, i.e. the thickness of the peat layer can be known, as well as layers with different water content and different degree of decomposition and botanical composition. You can also see the stumps in the peat and the boulders in the bottom layer of the deposit.<\/p>\n\n\n\n<p>The advantage of georadar over drilling a deposit is efficiency and continuous data. However, the interpretation of radar data requires specific knowledge and experience. Our radar expert is Hannes T\u00f5nisson, a senior researcher at the Institute of Ecology in Tallinn University with great experience. As georadar is relatively heavy, we use an 8-wheel off-road vehicle to tow it.<\/p>\n<p>Georadar surveys are needed in the Life Peat Restore project area to gain a better knowledge of the geological structure and development of the restoration area. It helps better to predict the processes that will take place after the restoration of the water regime.<\/p>\n<p>&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"700\" height=\"393\" src=\"https:\/\/life-peat-restore.eu\/en\/wp-content\/uploads\/sites\/7\/2020\/08\/hannes-georadariga.jpg\" alt=\"\" class=\"wp-image-2769\" srcset=\"https:\/\/life-peat-restore.eu\/en\/wp-content\/uploads\/sites\/7\/2020\/08\/hannes-georadariga.jpg 700w, https:\/\/life-peat-restore.eu\/en\/wp-content\/uploads\/sites\/7\/2020\/08\/hannes-georadariga-556x312.jpg 556w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><figcaption>Georadar behind the off-road vehicle &#8211; this is how the measurements were held.<\/figcaption><\/figure>\n\n\n\n<p>We use two antennas \u2013 one for the upper two metres peat (the 300 MHz antenna) and other (70 MHz antenna) for deeper peat.
