    Magnetotelluric array in the central Finnish Lapland I: Extreme data characteristics
    (Elsevier, 2020) Autio, U.A.; Smirnov, M.Yu.; Geologian tutkimuskeskus; Geological Survey of Finland
    We present magnetotelluric (MT) data from the northern Fennoscandian shield, which show extreme behavior due to the complex geoelectric setting left behind by the tectonic reworking of the Archaean bedrock during the Palaeoproterozoic. The core of the MT data set from the central Finnish Lapland were acquired in 2014 in the context of the MaSca-project. Extreme data are defined by the condition where the determinant of the real and/or imaginary part of the impedance tensor becomes negative. This is related to, but is a more anomalous condition than out-of-quadrant off-diagonal impedance phases. Physically, these are associated to reversal of e.g. the electric field as compared to its direction for one-dimensional resistivity structure. So far, only few examples of extreme data have been explicitly reported in geophysical literature. Data previously classified as erroneous might belong to the class of extreme data instead and data quality analysis should take this into account. A resistivity contrast of at least ca. 1:1000 is required to observe extreme data, as indicated by synthetic modelling studies. Extreme data are challenging from a modelling point of view and thus also drive the need for new developments in forward and inverse codes for MT.

    A geologically-based approach to map arsenic risk in crystalline aquifers: Analysis of the Tampere region, Finland
    (Elsevier BV; Zhongguo Dizhi Daxue, 2019) Pedretti, Daniele; Luoma, Samrit; Ruskeeniemi, Timo; Backman, Birgitta; 0000-0001-7677-3948; Geologian tutkimuskeskus; Geological Survey of Finland
    The study illustrates the critical role of accurate geological structural mapping to delineate crystalline aquifer zones more prone to high health risk due to elevated dissolved As in drinking wells. The analysis revisits the results from more than 1200 groundwater samples collected over ten years from domestic wells across the Tampere region (Finland).
