The LIAG's two-week lecture series begins on 22 March with a new programme on specialist insights into ongoing projects and geophysical method applications.
With numerous formats, the LIAG presented itself with exciting research topics at the annual conference of the German Geophysical Society (DGG) from 7 to 10 March.
Research at LIAG simply explained: The seismic measuring instruments developed at the institute are used to gain knowledge about processes and structures as well as changes in the subsoil, which is difficult to access. This is particularly important for issues relating to groundwater and geohazards. But how exactly do we work with the method?
A new DFG project enables research on near-surface faults at the Osning Lineament in northern Germany in the context of neotectonics - so far little is known about the reactivation of the fault. However, there have been several earthquakes in the past 400 years.
The EU Commission has asked for feedback on the topic "Climate change - restoring sustainable carbon cycles". In its commentary, the LIAG points out the possibilities of using geophysics to improve the understanding of CO2 storage. It recommends detailed studies in laboratory and field environments and a combination of soil, geochemical and geophysical methods to assess carbon uptake under diverse conditions and from laboratory to field scale.
"Meet the Scientist": LIAG researchers answer questions from the interested public on the topics "Earthquakes in focus" (4.11.) and "Drones as measuring platforms: Geophysical exploration" (8.11.) on November of Science in cooperation with FZ:GEO online. Participation is free of charge.

Meeting with Lord Mayor City of Hannover Belit Onay at the opening of the "November of Science" aka #knowember: The #LIAG is a new member of the "Initiative Wissenschaft Hannover"! With this cooperation, LIAG and its partners will strengthen the attractiveness and #internationalisation of Hannover as a science location.
In the DESMEX II project, a helicopter with a flight probe will explore the geological subsurface in the western Harz region (north of Germany) at an altitude of about 70 metres as part of a geophysical measurement campaign starting on 23 August. In addition to its involvement in the ground measurements, the LIAG is also significantly involved in the development of a programme for complex data processing in order to make the structures in the subsurface visible in a 3-D model.
New piece of the puzzle for understanding changes in future natural systems: In the Lichtenberg project, the LIAG and partners researched landscape stability and development during the Eemian warm period about 120,000 years ago in the Wendland region of Hanover. The Eemian is climatically comparable to the forecasts for the 21st century.
Leibniz institutions and LIAG launch novel research initiative: Scientists from a wide range of disciplines from Leibniz Association institutions are launching an initiative for "Integrated Earth System Research". Together with partners from Germany, Europe and other countries, they will investigate the current epoch of the Earth’s history, which is strongly influenced by humans, in a coordinated and interdisciplinary way as never before. The findings will point out both high-risk and safe development paths for politics, business and civil society.
On the recommendation of the German Research Foundation (DFG), the Joint Science Conference (GWK) decided on 2 July to fund the National Research Data Infrastructure for Earth System Research (NFDI4Earth) consortium and nine other consortia. This concludes the second round of calls for proposals, in which 16 initiatives applied for funding. With the help of the National Research Data Infrastructure (NFDI), data from science and research is to be systematically made accessible, secured, made more widely available and networked internationally.

Climate-friendly and reliable - this is how near-surface geothermal energy is proving itself in more and more practical examples for heating and cooling buildings. It is therefore high time to recognize its potential as a possible key to the heat transition and to use it even more intensively. On May 5 and 6, numerous experts from politics, companies, authorities and research discussed how this can be achieved at the North German Geothermal Conference organized by BGR, LBEG and LIAG.
How did the climate in the Alpine region change during the ice ages and how did it shape glaciers, flora and fauna over the millennia? The LIAG, in cooperation with the Albert Ludwig University in Freiburg and the State Office for Geology, Raw Materials and Mining in the Freiburg Regional Council (LGRB), is starting three research boreholes near Winterstettenstadt at the beginning of April. The boreholes, which are up to 160 meters deep, mark the start of the international project "DOVE - Drilling Overdeepened Alpine Valleys". This aims to reconstruct the spatial and temporal climate development during the ice ages over the past 2.6 million years in the entire Alpine region.

How can we imagine the Cretaceous period in Lower Saxony, Rehburg - how far exactly did the inland sea extend at that time and what did the coastal region look like where the dinosaurs lived? Geophysicists from LIAG are measuring the properties of the sediments in a 180-meter-deep borehole drilled by the State Office for Mining, Energy and Geology (LBEG) in Rehburg in the Nehrenbruch, near the Steinhuder Meer, in January to help answer these questions, among others.
According to the current state of research, the eastern Periadriatic Fault System (PAF), on the border between the Eastern and Southern Alps, shows barely any historical and instrumental earthquakes - although it is one of the most important tectonic features of the Alps. In this new project, the Leibniz Institute for Applied Geophysics (LIAG) and the Friedrich Schiller University Jena are now using new dating methods, which for the first time will allow the most recent geological fault activities to be revealed.
Full press release
Neotectonic movements on faults can be a major hazard. In northern Germany, however, little is known about neotectonic activity, despite evidence of it. At the Osning Lineament on the southern edge of the Lower Saxony Basin, there have been ten earthquakes in the last 400 years, one in 1612 with particularly severe consequences for Bielefeld. The project aims to demonstrate the significance of near-surface faults in relation to neotectonic activity - and why the Osning Lineament in particular is unique.

An international team of Geoscientists met in the middle of October in the city of Xi’an (China) for a workshop in preparation of a potential large-scale scientific project. The “International Scientific Drilling Programme” (ICDP) supports scientists to conduct international drilling projects. The international teams solve questions of high societal relevance, such as the past climate development. One of the next scientific wells might be drilled in central China, in the so-called Weihe basin. The drill is supposed to be about 7,500 m deep, in order to understand the palaeo-climate of the past 50 Mio years in detail. Two scientists of the LIAG have been involved in the workshop, and may join the drilling project. Their contribution would be knowledge in the field of cyclostratigraphy, which gives information upon age and sedimentation rates of rocks. Additionally, petrophysical investigations, by using especially the method of spectral induced polarization, which has been never utilized for ICDP projects before, have been proposed as potential project work.
Scientists from different German universities and research institutes have met at the beginning of October in Hannover, in order to talk and to discuss about new methodical and technical developments in the field of induced polarization. At the workshop, which was organized by LIAG staff, new methodical approaches to explore water-rock interactions were introduced. Furthermore, results of a time-domain IP field survey, which is amongst others used to investigate groundwater pollution, have been discussed. The working group IP of the German Geophysical Society meets half-yearly. These meetings are used for scientific exchange and networking, as well as especially for the strategic and content alignment of this methodical research field.
Within the framework of the Bund-Länder Initiative for the support of the National Research Data Infrastructure (NFDI), higher education institutions, non-university research institutions, sector research institutions and other publicly-funded information infrastructure institutions have the opportunity to join together in thematically/methodologically oriented consortia in order to submit a joint application for funding. The selection procedure is organised by the DFG. As early as 4 July 2019, LIAG submitted an expression of interest for a geology/geophysics consortium to the DFG, after it became clear that no other NFDI consortium emphazises on geological/geophysical data of the upper Earth crust.
On 9th of October, 2019, a kick-off meeting took place in the Geocentre Hannover under the lead of the LIAG to gather interested institutions with geological/geophysical data of the Earth crust. 21 representatives from universities, non-academic research institutions and geological surveys participated to exchange information about the existing research data infrastructure of the various geological/geophysical sub-disciplines and to discuss objectives and further steps for a geological/geophysical NFDI consortium.
The participants agreed in the necessity of a NFDI for the solid Earth crust, which is complementary to the climate research in Earth Sciences. As a first result, a new name was voted on. The preliminary "NFDI for Solid Earth" becomes "NFDI Lithosphere". In contrast to many other NFDI consortia, this consortium is still open for further members. The next meeting is scheduled for January 2020 in Hannover.
The working group on induced polarization meets twice a year. It consists of researchers from twelve different universities and research institutes. Induced polarization was originally developed for the exploration of ore deposits. By applying an electric current, an electric field is generated, and should expand unhindered in the subsurface. Sometimes metallic mineral grains block the pore space and therefore the flow paths of the electric current. The electrical charge accumulates in some areas and forms a kind of pattern. The researches can measure this electrical information and deduce, for example, whether the underground contains ores or contaminated sites or whether the groundwater is polluted. Matthias Halisch (LIAG) is hosting this year’s AK meeting at the Geozentrum Hannover. More than 12 presentations and as many scientific posters are waiting for the attendees of the meeting in October. Basic research will be discussed in the working group as well as questions of application or technical innovations.
About 2.6 million years ago, the peaks and valleys of the Alps were much higher. However, the advancing glaciers first eroded deep into the bedrock during different ice ages. The overdeepened valleys were filled with different sediments at the same time. Within the framework of the DOVE project, researchers from the LIAG and other partners will to use these sediments to draw conclusions on the climate history of the Alps. In Germany, Austria and Switzerland, the researchers will try to understand the valleys using core drillings. In order to provide the best possible information about the various glacial events, researchers need to know exactly where they have to drill. At this moment, with the help of the seismic method, employees from LIAG are clarifying this question in Basadingen, Switzerland. Using various seismic measuring methods, they look as deep as possible into the underground of the valleys to find the best location for drilling next year.
At the end of August, the partners of the DESMEX II project met to start the three-year project. The follow-up project to DESMEX I, is funded by the German Federal Ministry of Education and Research (BMBF), and intends to use electromagnetic methods in order to find deposits of ores and critical minerals at depths of more than 500 metres. So far, there are only limited methods to reliably explore deposits at greater depths. In the DESMEX project, the partners from science, public administration and industry developed sensors to measure the electromagnetic fields generated in the ground more accurately. In order to obtain the most comprehensive image possible, the sensors will be mounted on helicopters, including drones, and flown over areas several square kilometers in size. The LIAG researchers are developing algorithms to reconstruct a precise image of the subsurface from the measured data. In the new project phase, the focus will be on applying the developed sensors and algorithms, refining them and making them ready for practical use.
Dust storms are quite common in India. Repeatedly, the wind carries large quantities of dust into the Asian country, sometimes across long distances. There have also been dust storms in India thousands of years ago, making them suitable for reconstructing local climate history. If the climate is rather warm and humid, thick soils form. If, on the other hand, it is cold and dry, the dust remains a loose and gray/ochre sediment. Christian Zeeden (LIAG) has recently travelled to Kashmir to take sediment samples together with colleagues from the University of Kashmir. In the laboratory they will determine how old the samples are and under which climatic conditions they have deposited. If these initial studies are promising, Zeeden and his colleagues intend to collect comprehensive data from northern India in order to compare the climate development of the region with surrounding Central Asia.
In March 2019, the joint IODP and ICDP Colloquium took place in Cologne/Germany. The colloquium was a meeting place for those geoscientists who are drilling on the seabed, on land, or in lakes around the world and who are using drill cores to study the origin and climate of planet Earth. During this conference, two science journalists interviewed Dr. Thomas Burschil (LIAG) about his work on overdeepened valleys using the example of the Lienz Basin. Valleys like the one in East Tyrol have been filled with sediments since the last cold period. Originally, some Alpine valleys were much deeper than they are today. The result of the interview has now been published on the planeterde® website.
About 70,000 years ago, Neanderthals lived in Wendland, on the border with Saxony-Anhalt. Researchers at the Max Planck Institute for Evolutionary Anthropology were able to identify them using tool finds. However, why did the Neanderthals settle so far north, while large parts of northern Europe were covered by ice? The scientists assume that the Neanderthals lived near a lake that was fed by the water of the River Elbe during the Pleistocene. The Max Planck Institute asked LIAG and LBEG for support to investigate the geological structure of the site. With the help of auger and core drillings, the geoscientists are investigating the lake and want to unlock its secrets: How often did the lake dry out? What living conditions had the Neanderthals on the lake shore? And for how long could they rely on stable conditions?
Not all questions have been answered yet. In autumn, further drilling will be carried out to learn more about the living conditions of the Neanderthals in Wendland 70,000 years ago.
For the last four years, Sarah Hupfer worked on her dissertation in the junior research group "Subrosion" at the LIAG. At the beginning of July, she submitted her completed doctoral thesis to the Clausthal Technical University and is now waiting for her oral defense. In the subproject "Petrophysics" she investigated the transport and dissolution processes that take place in carbonate rocks (limestones). Among other things, she used the "Spectral Induced Polarization" (SIP) method. With her doctoral thesis, Sarah Hupfer is doing basic scientific research. She used the SIP method to determine systematically the complex electrical properties of different carbonate types for the first time. This basic knowledge of limestone is an important key component that will enable researchers to predict better future subrosion processes in which the subsoil is leached and becomes unstable.
The LIAG congratulates Sarah Hupfer on her completed dissertation and wishes her every success in her defense.

In the province of Xinjiang in northwestern China, the ground is burning. This is because coal mining repeatedly leads to coal fires. The coal is located relatively close to the surface and is particularly reactive. Improper handling brings it in contact with atmospheric oxygen, so that the coal ignites spontaneously. Once it burns in the ground, the fires are difficult to extinguish, as the fire is constantly supplied with oxygen through self-generated cracks. On the surface one recognizes hidden fires by factors like temperature increases, gas leaks and changes in the electromagnetic properties of the subsurface. With the help of numerical modeling, researchers want to understand how coal fires arise, spread and can be extinguished efficiently. Dr. Manfred Wuttke (LIAG) introduced Chinese colleagues to the possibilities of geophysical exploration and numerical modeling of coal fires at a joint German-Chinese workshop at the University of Urumqi, the capital of Xinjiang. This workshop is part of the XJU-LIAG Joint Center for Underground Coal Fire Research. Next year, a return visit of the Chinese scientists to another international workshop in Hanover is planned.
Sumiko Tsukamoto (LIAG) conducts researches on the age determination of sediments and rocks using luminescence and electron spin resonance dating. Such age determinations are important to understand the temporal changes of climate, for example the age and duration of cold and warm periods, in different regions of the world. The scientists of this research field meet regularly at conferences all over the world. However, there is yet no organization through which the community can network and advance common goals. The scientific community will change this and found the "Trapped Charge Dating Association (TCDA)". The members of the working group recently elected Sumiko Tsukamoto (LIAG) as Chair. She thus bears the decisive responsibility for the formation of the professional association.

Nico Skibbe is a PhD student at LIAG and develops a software for the evaluation of surface NMR. Nuclear magnetic resonance (NMR) has long been used to visualize underground structures or water without drilling holes. So far, changes in more than one direction can only be accounted for using proprietary software and their capabilities are limited. Changes to the left and right of the measurement often had to be neglected, using the previous evaluation programs. With the new program, this is no longer necessary. The idea was awarded the Paper Prize at the SAGEEP Conference, a major international conference on applied geophysics. Thanks to the award, Nico Skibbe has the chance to present his idea at the Near Surface Geoscience Conference and Exhibition in The Hague in September.

LIAG strengthens and extends its scientific cooperation in the research field of geothermal energy utilization with various Latin American universities, research institutes and state energy suppliers. A memorandum of understanding has already been signed with the Universidad de Sancti Spirítus José Martí Pérez, Cuba at the beginning of the year. A similar agreement with the Universidad Técnica Federico Santa María in Valparaíso, Chile is nearly completed.
The sustainable use of water resources is a particular challenge in coastal regions worldwide. Salinisation can endanger the groundwater and thus the drinking water supply. For a long-term study of the freshwater-saltwater boundary in the subsurface, LIAG employees recently installed a vertical electrode chain in the area close to the Ems-Jade Canal at a depth of about 30-50 m. With this measuring system, physical parameters are recorded daily and evaluated as part of the go-CAM project.
