Geophysics in Skäremo near Svenljunga
Or a November day in the sand. Author: Erik Sturkell.
On Sunday the 8th of November Gabrielle, Glitnir, Deli and I (Erik) joined Eric Hegardt and Erik Meland far out in the woods just south of Svenljunga, to do a refraction survey. Eric and Erik had a job to make an estimate of sand volumes for a possible expansion of an existing sand pit. Three 120 meters long refraction lines were made, to determine the depth to solid rock and also if possible to detect the ground water table. In addition, a few profiles with the ground penetrating radar were made. We combined the data collection so the material can be used for a possible student project. Erik and Eric are an excellent team and the work was made during the light hours of the short day. Gabrielle and me took care of the levelling of the seismic line. We established two permanent benchmarks that can tie to an absolute height. Glitnir and Deli enjoyed the fieldwork for most of the time, but as Glitnir did not like the explosions, she retreated to the safety of the car for a while. However, in the afternoon she re-emerged happy to take part in the fieldwork again.
