1. Developing data processing program for a new radio magnetotelluric (RMT) instrument
University essay from Uppsala universitet/GeofysikAbstract : The radio magnetotellucic (RMT) method originates from (Tikhonov, 1950) and (Cagniard,1953) who discovered the possibility to estimate resistivity in the Earth’s subsurface using naturally occurring telluric currents. This through measuring the surface impedance of electromagnetic waves. READ MORE

2. Integration of Borehole, Ground, and Airborne Data to Improve Identification of Areas With Quick Clays in Sweden
University essay from Uppsala universitet/GeofysikAbstract : The main focus of the project was the comparison of results from a new towed transientelectromagnetic (tTEM) data set with existing data including airborne transient EM(ATEM), radio magnetotellurics (RMT), cone penetration test with resistivity (CPT-R),geotechnical interpretations and geological observations in a quick clay landslide site atFråstad close to Lilla Edet in south-west Sweden. The tTEM data set was processedand inverted twice in the software Aarhus workbench using different inversion constraintsand settings. READ MORE

3. Comparison of data analysis methods KMSProTF and MsDEMPCA using Magnetotelluric data
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : In this work two ways of processing controlled-source magnetotelluric (MT) data were tried and compared against each other. The aim was to evaluate the differences between a multivariate-based processing method to a bivariate processing method. The software KMSProTF represents conventional processing using bivariate and robust statistics. READ MORE

4. Processing of Noisy Controlled Source Audio Magnetotelluric (CSAMT) Data
University essay from Uppsala universitet/GeofysikAbstract : Controlled Source Audio Magnetotellurics (CSAMT) is a geophysical method for characterizing the resistivity of the subsurface with the help of electromagnetic waves. The method is used for various purposes, such as geothermal- and hydrocarbon exploration, mineral prospecting and for investigation of groundwater resources. READ MORE

5. Data processing of Controlled Source Audio Magnetotelluric (CSAMT) Data
University essay from Uppsala universitet/GeofysikAbstract : During this project three distinct methods to improve the data processing of Controlled Source Audio Magnetotellurics (CSAMT) data are implemented and their advantages and disadvantages are discussed. The methods in question are: Detrending the time series in the time domain, instead of detrending in the frequencydomain. READ MORE
