Electrical resistivity imaging data for hydrological and soil investigations of virgin Rospuda river peatland (North-East Poland)

Abstract. This publication presents data on geophysical measurements performed in the Rospuda wetlands located in North-Eastern Poland. The measurements were carried out by means of the the Electrical Resistivity Imaging (ERI) method, which so far was to our best knowledge never used in the River Rospuda wetland valley. The ERI data were collected in single survey campaign in November 2022 to account for the wet season. During the campaign two ERI profiles were measured. The aim of the field works was to provide the material for illustration of the arrangement of geological layers creating the wetland. The data repository contains detailed data descriptions for each survey site. The ERI data from the selected survey sites can be used first of all to create the conceptual numerical model of groundwater and surface water interaction in this environmentally valuable area, which is to a certain extent a scientific terra incognita, but also for hydrological investigation of hydraulic conductivity and hydrodynamic field, identify geological structure, and characterize engineering properties of the organic soils.
