Some Highlights of Finnish Research in Solid Earth and Applied Geophysics in the 20th Century

摘要

The development of non-seismic aspects of solid Earth geophysics in Finland is described along five major lines: geomagnetic research at observatories, applied geophysics to assist mineral prospecting and geological mapping, geothermal research, and induction studies. Finally examples of high-quality work on numerical modelling of electromagnetic geophysics are given. The paper describes first some key results from the earliest Finnish geomagnetic recordings, the Development of the Finnish geomagnetic observatory system and its present state.
