(2021)The German continental seismic reflection program DEKORP (DEutsches KOntinentales Reflexionsseismisches Programm) was carried out in the years between 1984 and 1999. The aim of DEKORP was to investigate the deep crustal ... -
Modellierung der Dichteverteilung in der Unterkruste unter dem Semail Ophiolithen
(2021)Der Semail Ophiolith im Osten der arabischen Halbinsel ist einer der größten und am besten zugänglichen Ophiolithkomplexe der Welt. Um die Obduktion und die weiteren Prozesse, die bei seiner Entstehung eine Rolle gespielt ... -
Induced micro seismicity due to raising mine water level in former coal mines in the eastern Ruhr area (Germany)
(2021)FloodRisk is an interdisciplinary project focusing on the effects of mine water level rise in bandoned coal mine regions in Germany. Such effects are heterogeneous ground uplift, stress changes due to the change in pore ... -
Wind Turbine Noise Reduction from Seismological Data
(2021)Over the last years, installations of wind turbines (WTs) increased worldwide. Owing to negative effects on humans, WTs are often installed in areas with low population density. Because of low anthropogenic noise, these ... -
Classifying infrasound signals at Mount Etna using pattern recognition techniques
(2021)The ongoing activity of Mount Etna and the proximity to the nearby population requires constant monitoring. Infrasound recordings play an important role in volcanic observation because explosive activity near or above ... -
Zerstörungsfreie Untersuchung von Stahlfaserbewehrung in Beton mittels Computertomographie, Spektral Induzierter Polarisation und Ultraschalltransmission
(2021)Stahlfaserbeton (FRC) ist ein zementgebundener Hochleistungswerkstoff, der in vielen Bereichen des Bauwesens breite Anwendung gefunden hat, insbesondere dort, wo hohe Zugfestigkeit, strukturelle Integrität und innovatives ... -
NEXD: A Software Package for Seismic Wave Simulation in Complex Geological Media – New Developments
(2021)NEXD is an open source software package for the simulation of seismic waves in complex geological media. This includes elastic, viscoelastic, porous and fractured media with complex geometries. For the computation of the ... -
TRIPLE – Ice Data Hub, Model-based Mission Support and Forefield Reconnaissance System
(2021)The ocean worlds of our Solar System, like Saturn's moon Enceladus and Jupiter's moon Europa are covered with ice. Recently, these icy moons gained further scientific interest, as they are attributed some potential to ... -
Simulation of Seismic Wave Propagation in Porous Rocks Considering the Exploration and the Monitoring of Geological Reservoirs
(2021)Modelling the propagation of seismic waves in porous media gets more and more popular in the seismological community since it is an important but challenging task in the field of computational seismology. The fluid content ... -
Computational Modelling of Coupled Heat Transport between the Heterogeneous Earth and an Overlying Ice Sheet
(2021)Due to a complex interplay between the Earth and overlying ice sheets, a large variety of subglacial landforms developed. One example is the in the North German Basin widely spread phenomenon of tunnel valleys. An observed ... -
Implementierung und Bewertung einer auf statistischen Momenten basierenden Methode zur automatischen Bestimmung der Einsatzzeiten von P- und S-Phasen
(2021)Für die automatische Detektion von Erdbebenphasen in seismologischen Daten haben sich STA/LTA-Picker bewährt. In dieser Arbeit stellen wir einen alternativen Ansatz vor, der die statistischen Eigenschaften des aufgezeichneten ... -
Dipolinversion mit Komponentengradienten in der Aeromagnetik
(2021)In der Aeromagnetik werden zur Kampfmitteldetektion Multikopter eingesetzt, um belastete Flächen schnell und mit hoher Auflösung zu kartieren. Dabei wurden bisher hauptsächlich einzelne Totalfeldsensoren oder Fluxgate-Magnetometer ... -
Die Form und Füllung des glazial-übertieften Basadingen-Beckens, abgeleitet aus hochauflösenden reflexionsseismischen Messungen - DGG 81. Jahrestagung 2021- SE Seismik, 01.03. - 05.03.2021
(2021)Übertiefte Täler in den Alpen ermöglichen uns glaziale Sedimentation und somit einen Teil der quartären Klimageschichte zu verstehen. Reflexionsseimsik kann dabei verwendet werden, um punktuelle Bohrlochdaten in die Fläche ... -
Möglichkeiten und Grenzen der zerstörungsfreien Erfassung niedriger Feuchtegehalte in teilgesättigten Sandsteinen mit 1H-NMR
(2021)Die zerstörungsfreie Ermittlung der Materialfeuchte in Baustoffen ist für das Bauwesen von großer Bedeutung, denn ein erhöhter Feuchteeintrag kann zu Schimmelbildung, Alkali-Kieselsäure-Reaktionen, Korrosion etc. führen ... -
