A Numerical Assessment of Electrical Imaging for Seawater Intrusion Monitoring in Heterogeneous Coastal Aquifers
Speaker: Andres Gonzalez Quiros,
Bio: Andres Gonzalez Quiros is a research scientist at the British Geological Survey (UK) based at the Lyell Centre (Edinburgh). He holds a BSc in Geology, MSc in Geological Resources and PhD in Mining Engineering specialized in hydrogeophysics (“Identification of hydrogeological properties via joint use of microgravimetry and pumping test data analysis”). His main research interests are the development of multiphysical modelling approaches to integrate quantitative information (geophysics, remote sensing) to build, inform and calibrate hydrogeological numerical models. Previously he hold a “Royal Society – Newton International Fellowship” (“Monitoring and coupled hydrogeophysical modelling of saltwater intrusion in coastal aquifers “) at the University of Aberdeen (UK) and worked as a postdoctoral research fellow in the numerical modelling of water flow and contaminant transport to assess the environmental impact of closed underground coal mines within the EU RFCS project MERIDA (“Management of Environmental Risks During and After Mine Closure”). He has been awarded with the IAMG Mathematical Geosciences Student Award 2014 (“Study of the gravity anomaly produced by a pumping test in an unconfined aquifer: coupled modeling and survey optimization”) and the “Alfons Bayó” Early Career Award 2020 from the International Association of Hydrogeologists – Spanish Chapter.
Characterization of a complex fault system by 2D acoustic Random Objective Waveform Inversion
Speaker: Daniel Koehn, lecturer and research scientist at the Institute of Geoscience at Christian-Albrechts University Kiel
Bio: Dr. Daniel Koehn is a lecturer and research scientist at the Institute of Geoscience at Christian-Albrechts University Kiel (Germany).He studied physics and geophysics in Kiel and Freiberg, before obtaining a PhD in 2011. His PhD thesis deals with the development and application of the elastic seismic Full Waveform Inversion open-source software package DENISE Black-Edition. Daniels current research focuses are the field data application of seismic SH/PS Full Waveform Inversion/Imaging on different scales. From non-destructive testing using ultrasonic waves to near-surface characterization in engineering geophysics and archaeological prospection with surface waves to the inversion of body wave data to map complex fault systems and geothermal reservoirs on the exploration scale.
Speaker: Magdalena Markovic
Bio: Magdalena is PhD student at Uppsala University (Sweden) and her research deals with reflection seismic imaging and interpretation for deep targeting of mineral deposits. Her research focus is application of deep-learning algorithms for diffraction delineation and denoising in hardrock environment. Successful case studies cover iron-oxide deposits in Sweden and massive sulphides in Canada, some of which show clear diffraction signature suitable for deep-learning solutions.
New electromagnetic sensors as the drive for a much more widespread usage of geophysical subsurface images
Speakers: Esben Auken
Bio: Esben Auken is Deputy Director at the Geological Survey of Denmark and Greenland (GEUS) and a former professor of geophysics at the Department of Geoscience, Aarhus University, Denmark. He gained an MSc (1991) and PhD (1996) in geophysics from Aarhus University. As a professor he did high level research with electrical and electromagnetic methods for high resolution mapping of the shallow subsurface with focus on surface and groundwater processes. Today he is responsible for GEUS’s research program within water and climate adaptation, research and innovation on the highest level and for the benefit of the Danish and international society. He is still an active researcher with focus on development of geophysical instrumentation. He co-founded three successful spinn-out companies: SkyTEM Surveys Aps (2003), Aarhus GeoSoftware ApS (2015, in 2021 owned by Seequent) and Aarhus GeoInstruments Aps (2020).
