2 EMIW 2018 | Helsingør, Denmark

Welcome On behalf of the IAGA Division VI Committee, it is a pleasure to

welcome you to the 24th International Electromagnetic Induction Workshop in Helsingør, Denmark.

Since 1972, when the first EMIW was held in Edinburgh, Scotland, we have held 23 international electromagnetic induction workshops in many countries across the world. Posters, talks and reviews, presented at our workshops constitute the “gold reserve” of EM induction studies and have contributed greatly to the development and evolution of our sub-discipline.

Since 2015 we are a sixth division of the International Association of Geomagnetism and Aeronomy, while IAGA is one of eight associations of the International Union of Geodesy and Geophysics, and IUGG is one of 32 scientific unions of the International Council for Science. Thus, we are a branch of a large scientific family.

I’m sincerely grateful to the members of the Local Organizing Committee and its chair, Prof Toivo Korja for the organization of the workshop within an extremely short time limit. They have done their best to make the Nordic Workshop possible.

I greatly appreciate our sponsors’ support which made it possible for many young participants to attend the workshop, to say nothing about other important issues.

I’d like to thank Dr Stephan Thiel and other members of the financial support committee for coordinating fund raising and distribution of funds. I’d like to thank the members of the Division VI Committee, Program Committee and the session conveners who contributed greatly to the preparation of the workshop’s scientific program.

We are very grateful to the scientific reviewers and everyone who has contributed posters or oral presentations for the workshop. In addition, I would like to encourage young colleagues to communicate with other participants, expand international contacts, establish new cross- country scientific links, and not just attend different events. Make sure that you get the most of the workshop in terms of communication.

I wish you an enjoyable exchange of ideas and inspiration for new challenges in the field of science. Have a nice time in legendary Helsingør!

(Nikolay Palshin)

Nikolay Palshin Chair, IAGA Divison VI Committee


Dear 24th EMIW delegates, Welcome to the 24th EMIW in Helsingør, Denmark! The workshop is a joint endeavour of the Nordic countries: Denmark, Finland, Iceland, Norway, and Sweden, and their associated territories Greenland, the Faroe Islands, Svalbard and the Åland Islands. They are located in the NW part of the Eurasian plate and in NE part of the North-American plate.

When traveling by train from Copenhagen to Helsingør (Elsinore), globetrotters note a rather flat topography with only minute variations. A geophysicist might add that the surficial calmness is a decoy masking larger variations at depth. Helsingør is located within the Sorgenfrei-Tornquist zone, the NW branch of the Trans-European Suture Zone - TESZ. This major European suture zone and paleo plate boundary separates the old Precambrian Europe in NE from the younger Phanerozoic Europe in SW. In Helsingør, Denmark, the crust is 35 km in thickness and across the Øresund strait, in Helsingborg, Sweden, the crust is 50 km in thickness. At greater depths, the TESZ marks the boundary between thick Precambrian lithosphere and thinner Phanerozoic lithosphere. From the Earth scientist’s perspective, Denmark is indeed a fascinating place.

Geological record spans over 3700 Ma in the Nordic countries. The structure of the lithosphere reflects process spanning from the frozen Precambrian to modern active mid-ocean ridge extension and hot-spot tracking and from closing of the Iapetus to rising of the recent rise of Keel Mountains in Norway/Sweden. The area and its underlying lithosphere is still recovering from the last ice-age, and ongoing postglacial rebound is still shaping the surface heights and the location of the coastal line. The interplay between solar wind and the Earth’s geomagnetic field is expressed as the magnificent northern lights, Aurora Borealis making technological systems vulnerable (GIC).

You are very warmly welcomed to the workshop! We hope for a successful workshop with inspiring presentations and discussions as well as for new emerging collaborations and future scientific initiatives. We also hope that you will also have time to enjoy Helsingør and its surroundings and maybe take a ferry to have a late-night dinner in Helsingborg, Sweden.

The Local Organizing Committee (LOC) would like to thank our sponsors: Carlsberg Foundation, Phoenix Geophysics, Metronix Geophysics, KMS Technologies, Nord-West Ltd., SkyTEM, Aarhus GeoSoftware, Crystal Globe, Geonics, IUGG, IAGA and GW Hohmann Memorial Trust. Their financial support has enabled us to continue the policy of the reduced student registration fee and student travel grants.

We also wish to thank Nick Palshin, the chair of Program Committee (PC), and other members of the PC; Stephan Thiel and Ute Weckmann, chair and co-chair of the Financial Support Committee (FSC), and other FSC members. We would also like to thank Oliver Ritter and Maxim Smirnov for maintaining the IAGA Div VI web pages and database of the workshop, and all session conveners for evaluating abstracts and drafting the sessions. We wish to thank the DTU team: Nils Olsen and Maria Gleerup Tammelin, for their work on visa invitation letters. Finally, we wish to thank Sofie Gradmann and Vikas Baranwal for editing this program book. Thanks also to Saman Tavakoli for the coordination of the work of Student Assistants Team as well as to all SAT members.

The Excursion Thursday, August 16th, 8:00 – 19:00 The excursion will bring us to some fine historical places in Northern Sealand. After half an hour ride on the bus from Helsingør, we will reach Hillerød with Frederiks castle and exploring its beautiful park around. The second bus stop bus is in Roskilde, where we will visit the dome and the Viking ship museum, which give insight into thousands of years in Danish history. In between the visits we will have lunch, a picnic in an open-air theatre in Folkeparken. In the afternoon we will continue to Klampenborg and stay for an hour or longer in the oldest amusement park in the world, Bakken. Entrance for Bakken is free, but you have to pay for your activities. From here, you can either take the excursion bus back to Helsingør, arriving there at about 19 h – or you are staying longer and going back by train (taking about 40 min) on your own.

Further details of the excursion you will find in the web pages of the workshop.

Please note: • Buses leave at 8.00 h from the bus parking

behind Kulturværftet, NW of Værftshallerne,Kronborgvej. Please, be there well ahead intime.

• Bring your name badge! Entrance fees in Roskilde are included.

• In case of poor weather, do not forget yourrain gear. Lunch will be served in the open-air theatre.

• Have some Danish crowns in cash, you may need them in Bakken and elsewhere.

• Once having chosen your bus (which is numbered),you should NOT change it during the excursion – otherwise you and the LOC may get in trouble.

• Buses will be back in Helsingør at 19 h.

Enjoy, and have a wonderful day in Northern Sealand.

Location: GEUS – Geological Survey of Denmark and Greenland Øster Voldgade 10, 1350, Copenhagen C Theodor Sorgenfri Auditorium


Session Descriptions SESSION 1: INSTRUMENTATION, SOURCES AND DATA PROCESSING This session solicits contributions on EM data processing, source field analysis, instrumentation, and field practice. We welcome contributions on all aspects of data processing, including theory and practical applications. Development and application of time lapse observations (monitoring) of transfer functions and other parameters as well as new approaches to estimation of transfer functions and their uncertainty can be presented here. We also solicit studies on source fields, whether controlled or uncontrolled. This includes characterization of external source spatial structure and temporal variability, novel (distributed) transmitter configurations, and effects of finite spatial-scale sources (natural and anthropogenic) on transfer functions. Contributions on new instrumentation and field practice and related methodological developments are also appropriate for this session. Studies of sensor fidelity either by noise level analysis or by field comparison with other sensors are appropriate. Sensors can include ohmic or capacitively coupled electrodes, magnetometers, and any other instruments whose inter-comparison with EM data demonstrates new insights.

Conveners: Pierre Wawrzyniak, Karl Kappler, Maxim Smirnov

SESSION 2: THEORY, MODELLING AND INVERSION The geo-electromagnetic phenomenon is fundamentally governed by Maxwell's equations, in which the Earth's electric properties are often the sought parameters associated with specific geoscientific problems. This session covers all aspects of theory, modelling and inversion when working with Maxwell's equations. We invite contributions on advances in EM theory, analytic and numerical solutions, physical modelling, imaging and inversion algorithms, software implementations, as well as case studies related to the above topics. We further welcome methodological contributions, which solve or provide new insight into multi-disciplinary data integration, complex earth medium modelling, 3D/4D inversion algorithms and initiatives like open source software that benefit the community at large. Works that make good use of emerging technologies, like machine learning and cloud computing, are also warmly invited.

Sub-sessions: S2.1 - Theory; S2.2 - Modelling; S2.3 - Inversion (general); S2.4 - Inversion (joint or constrained); S2.5 - Software and Framework

Conveners: Alexander Grayver, Dikun Yang, Tomas Kalscheuer, Hao Dong

SESSION 3: EXPLORATION, MONITORING AND HAZARDS EM methods are widely used for obtaining electrical properties of the underground (the resistivity, magnetic permeability, dielectric constant, or IP parameters) ranging from the near surface to the upper mantle. Different techniques and their combinations are applied for different tasks in exploration, monitoring and hazard assessment. We are pleased to invite researchers to submit abstracts of their works related to recent developments and case studies that highlight the role of EM induction in mineral exploration, oil and gas, groundwater and geothermal, environmental and engineering, and natural hazards assessment. We will appreciate contributions on different aspects of EM methods application to exploring, tracking, fluid injections and sequestration studies. We warmly solicit contributions that emphasize and evaluate the role of EM methods to natural resources exploitation, hazard assessment through


EM monitoring both in seismic and volcanic environments. Finally, we also encourage contributions addressing the data processing and interpretation of EM exploration techniques aimed at lithological characterization as well as at determination of petrophysical and hydrophysical properties of rocks.

Sub-sessions: S3.1 - Exploration (Geothermal, Hydrocarbons, Minerals, Groundwater); S3.2 - Monitoring; S3.3 - Hazards

Conveners: Shimeles Fisseha, Jared Peacock,Ted Bertrand, Yin Changchun

SESSION 4: TECTONICS, MAGMATISM, GEODYNAMICS Electromagnetic (EM) methods provide information on the Earth’s electrical conductivity, a parameter that is sensitive to the presence of fluids, melts and/or conductive mineral phases. Fluid processes play a key role at subduction margins and in continental collision zones. Electrical resistivity models also allow us to map temperature variations and to image shallow and deep magmatic processes, phase transitions and mineralization. Therefore, EM methods play an important role in geophysical studies of major geodynamic processes in the Earth. We invite a wide range of crust and mantle studies in different tectonic settings, including active continent collision zones, subduction zones, stable tectonic settings and volcanic areas. We encourage submission of multiparameter geophysical-petrological studies, in which electrical conductivity models are used alongside other geophysical methods to provide new insights into tectonics, magmatism and geodynamics.

Sub-sessions: S4.1 - Tectonics; S4.2 - Magmatism; S4.3 - Geodynamics

Conveners: Wiebke Heise, Perla Piña-Varas, Kate Selway

SESSION 5: MARINE EM Marine EM encompasses both active and passive soundings of the sub-seafloor from the Arctic to the tropics and from mid-Ocean ridges to continental shelves. We invite contributions from authors working at all scales of marine EM, stretching from large arrays for offshore and amphibious exploration to borehole logging and monitoring. We welcome results of basic and applied research including the challenges inherent in running field campaigns, developing instruments, processing data, estimating errors, and implementing inversion algorithms. We encourage discussions on state-of-the art methods for marine magnetotelluric and controlled source electromagnetic data acquisition, inversion and interpretation as well as where active exploration is heading given recent emphasis in deep-sea mineral deposits, petroleum exploration and shallow water CO2 sequestration.

Conveners: Romina Gehrmann, Kim Senger, Yuguo Li

SESSION 6: ROCK AND MINERAL RESISTIVITY, AND ANISOTROPY The link between electrical resistivity from the laboratory/outcrop scale to lithospheric-asthenospheric scale is challenging due to several factors (sampling procedure, local heterogeneity, anisotropy on multiple scales, geological structure, coupling between rocks and fluids, etc.). Despite major experimental, theoretical and modelling advances a remaining future goal is the development of meaningful experiments and models that allow us to identify and quantify the relationship between causative processes and electrical rock resistivity on different scales and in different environments (P,T, fluids). This is a critical step in order to


unravel the complex evolution and dynamics of the earth's lithosphere-asthenosphere and also to develop predictive capabilities for energy applications. In this session, we therefore welcome studies that adopt novel approaches and combined methodologies using experimental and numerical methods in the laboratory and the field related to rock and mineral resistivity, as well as developments in the study of electrical anisotropy.

Conveners: Jana Boerner, Juanjo Ledo, Ute Weckmann

SESSION 7: GLOBAL AND PLANETARY STUDIES We solicit new contributions on induced electromagnetic fields at a planetary scale. We invite presentation of studies that shed light on the progress in our understanding of global electrical conductivity structures in the Earth´s mantle. Development of new methods of global forward and inverse modelling, use of new transfer functions, joint inversion for ionospheric sources and mantle conductivity, and interpretation of satellite magnetic field data are welcome. New methods that incorporate space physics constraints on the sources of electromagnetic induction at periods relevant to the Earth's mantle conductivity structures are particularly welcome. We also call for studies dedicated to magnetism and induction on other planets.

Conveners: Joan Campanya, Jakub Velimsky, Svetlana Kovacikova

SESSION 8: EM INDUCTION EDUCATION AND OUTREACH (POSTER SESSION) In addition to the advancement and application of electromagnetic induction science, members of IAGA Division VI play critical roles in education and outreach. In terms of education, this work may involve teaching undergraduate or graduate students, supervision of undergraduate or graduate research, or training new scientists how to use electromagnetic equipment. In terms of outreach, it may involve promoting large-scale electromagnetic projects to senior officials or other scientists, writing statements on the socioeconomic importance of electromagnetic induction studies, or providing entertaining visits to high school students. This session, the second of its kind at our electromagnetic workshops, is intended to collect posters highlighting novel, interesting, and/or important experiences from the teaching and outreach of electromagnetic induction. The sharing of ideas and information in these areas will help contribute to the overall public understanding of electromagnetic induction studies.

Phoenix also maintains a service division for specialized surveys, client training, and equipment testing. Phoenix equipment has been used in approx. 100 countries. In hydrocarbon exploration, MT complements seismic in poor-seismic areas; provides rapid reconnaissance of new basins where seismic is expensive or difficult; and sometimes shows direct hydrocarbon indicators. Phoenix EM/MT are also used in exploration for geothermal, base and precious metals, coal, diamonds, uranium, and some industrial minerals. Engineering uses include dam site studies, railway tunnel planning, and mining hazards prediction (water inrush in coal beds). Research applications include earthquake prediction research and crustal mapping.

Sponsors Metronix has released the 8th generation of MT data loggers in 2017. One of the outstanding features is the frequency range from 256 kHz down to DC. The LINUX based system records all frequencies continuously using opensource timeseries. The instrument including all sensors are automatically calibrated without user interaction. Data can be sent to your own cloud directly (encrypted transport). All metronix sensors are auto detected by the system and the calibration data is loaded into the timeseries. For the scientist and expert users this flexibility is a must and allows to make a competitive data processing with all available MT codes.
