23.03.06 - Introducing recent arrivals at CGF!
Tobias has an M.Tech in Computer Science from NTNU that focuses on HPC and optimising linear solvers connected to Newton-Raphson iterations of nonlinear systems using heterogeneous computing. His thesis was a collaboration between the CGF and the HPC-Lab to enhance today's cutting-edge CO2 storage simulation software. For his PhD, he will continue this work by combing different simulation software in a framework and investigate in which scenarios advanced physics modelling is advantageous as opposed to simplified analytical solutions. Tobias will be part of WP5.
Maren completed a M.Tech in Computer Science from NTNU with a specialisation in algorithms and HPC. Her Master's thesis was a collaboration between the CGF and the HPC-Lab at NTNU, where she analysed mixed-precision and GPU matrix accelerators for high-order FEM for seismic wave propagation. As part of WP5, Maren’s PhD research will concentrate on tools and techniques to facilitate the performance engineering of FWI codes on emerging computer architectures, primarily focusing on optimisations targeting data movement and especially looking at FWI for seismic imaging.
Claudi comes to us from the Center of Mathematical Research at the Autonomous
University of Barcelona, where he obtained his bachelor's degree in mathematics and was subsequently employed in the modelling group, working with cutting-edge mathematical advances and their implementation to real-life problems for various industry clients. While enrolled in a master's degree in modelling for science and engineering at the same university, he participated in a project on high-performance computing during his work placement and master's thesis at the Barcelona Biomedical Research Park. In his PhD thesis with WP5, he will be working on developing a

The disastrous magnitude 7.8 earthquake that struck Turkey and Syria on Monday 6th February was reported by our Partner, NORSAR and was also clearly observed on the seabottom fibre connecting Longyearbyen and Ny-Ålesund (Svalbard), which we are monitoring with DAS.
The image represents DAS data from roughly half an hour (vertical axis) and 60 km of the cable located in Kongsfjorden. The earthquake occurred at 01:17:35 UTC, as reported by USGS. The first arrival (P) is clearly observed at 01:25:42 (UTC). This wave travelled deep into the earth and took 8 minutes to arrive. The next observed signal (generated by the same earthquake) is the secondary (shear) wave arriving 18 minutes after the quake and the final (third) signal is the surface (Rayleigh) wave arriving 26 minutes after the quake.
The approximate epicentral distance to Svalbard is 4,780 km. If we assume that the P-, S- and surface- waves each travelled roughly the same distance we can estimate the following velocities for the three waves: 9.8 km/s, 4.3 km/s and 3.0 km/s.

We are delighted to announce the award of a CGF-spin off EU-project SUBMERSE (SUBMarine cablEs for ReSearch and Exploration), bringing in some 2.6 MEuro for CGF-partners, including funding for two new PostDocs at IES/CGF.
SUBMERSE responds to the call Next generation of scientific instrumentation, tools and methods (2022) (HORIZON-INFRA-2022-TECH-01). The project directly addresses challenges to develop a new world-class research instrument integrating already existing NREN and EPOS infrastructures and Copernicus Marine service. This project will enable continuous recording of these types of data for research use by NRENs for the first time, thus supporting diverse academic, industrial and governmental user communities. Through the integration with EPOS data infrastructure , existing research communities in solid earth (EPOS) and marine science (EMSO), industrial and public body communities can be complimented with entirely new types of data sets unavailable to them before, which it is believed will lead to new areas of research.

22.08.12
International interest continues to reverberate following the peer-reviewed scientific article by CGF researchers on using Fibre-Optic cables to listen to whales off Svalbard. A number of popular science channels and international newspapers have picked up on it, including The Independent, EOS Science News by AGU, Newsweek, La Nacion, Stern and others.
Norwegian media have also been featuring the paper, both locally and nationally, including:
Norwegian Science and Technology news (https://norwegianscitechnews.com/2022/07/eavesdropping-on-whales-in-the-high-arctic/)
The Svalbard Post (https://www.svalbardposten.no/arktis-hval-ntnu/tjuvlytter-pa-hvaler-i-arktis/488205)
NRK (https://www.nrk.no/tromsogfinnmark/forskarar-bruker-fiberkablar-for-a-tjuvlytte-til-kval-1.16036560)
Our work has even drawn the attention of Greenpeace, with the Norwegian Greenpeace leader Frode Pleym welcoming the research and efforts to reduce collisions between ships and whales.
22.07.06
Léa Bouffaut, along with several other CGF researchers, has published a paper in Frontiers of Marine Sciences, entitled "Eavesdropping at the Speed of Light: Distributed Acoustic Sensing of Baleen Whales in the Arctic".
The article details the first case of wildlife monitoring using Distributed Acoustic Sensing (DAS), employing an interrogator to monitor signals along a 120 km long fibre-optic cable in Svalbard. The test was conducted in cooperation with CGF partners ASN and Sikt in 2020 over a period of 40 days, with the researchers being able to record vocalising baleen whales, demonstrating the first time whale-sounds have been recreated from fibre-optic cables, without having to use underwater hydrophones.
With fibre-optic cables being globally available, this first example's success suggests DAS's potential for real-time and low-cost monitoring, allowing researchers to cover a much larger area than previously, with unprecedented spatial resolution. This highlights the huge potential for fibre-optic cables for underwater sensing.
The success is covered in a comprehensive write-up by the Norwegian SciTech news Gemini - read more here!
22.06.10
NTNU and Sikt installed a DAS (Distributed Acoustic Sensing) interrogator in Ny-Ålesund last week. The purpose of the test is to record environmental data from the area west of Svalbard over a long time period. Earthquakes, ships, whales and weather data are expected to be recorded. In August we plan to install interrogators also in Longyearbyen to extend the experiment for a shorter period of time (14 days). From CGF, Frode Storvik (Sikt), Kurosh Bozorgebrahimi (Sikt), Kristina Skarvang (NTNU) and Martin Landrø (NTNU) participated.

21.10.05 - More new arrivals at CGF!
After his Bachelors in Geoscience, Kevin worked for 1.5 years at GEOMAR Kiel and IPG Paris on seismic data from the Mid-Atlatic-Ridge, imaging crustal and upper mantle structures. Afterwards he pursued the IDEA LEAGUE Master in Applied Geophysics at TU Delft, ETH Zürich and RWTH Aachen. Within his Master’s Thesis he used ambient noise correlation techniques to constrain the subsurface reflectivity below NASA’s InSight lander on Mars. His PhD research here at the CGF will be anchored in WP3 and will focus on using DAS for monitoring shallow subsurface properties as a potential tool for landslide forecasting.
Kristoffer graduated with an M.Sc. in geophysics from the University of Bergen in August 2021. The theme of his Master’s thesis was the use of acoustic waves to estimate temperatures in the ocean over large distances. In particular, he worked on forward modelling in the Fram Strait, where the presence of non-geometric arrivals is causing difficulties in analysing the acoustic data. Here a new and efficient modelling technique based on the ray-Born approximation was introduced, which used a GPU to do the computationally-demanding raytracing. At CGF his research will focus on ray tracing and inversion in anisotropic media.
Nick studied his first master’s in Petroleum Geoscience at the University of Aberdeen and then worked as a logging geologist for a year before undertaking a second master’s in Applied Geophysics as part of the IDEA League programme between TU Delft, ETH Zurich and RWTH Aachen. His master’s thesis focused on leveraging advances in rotational seismology alongside applying machine learning techniques to efficiently classify and separate different wave-modes from large datasets. His research will focus on multi-physics modelling for in- well monitoring of production and injection wells using fibre-optic data as part of WP3.
21.10.03
A team of leading CGF researchers has just published an overview article entitled "Next generation geophysical sensing: exploring a new wave of geophysical technologies for the energy transition" in the October edition (volume 39) of 'First Break' in the special topic issue on 'Delivering for the energy challenge: Today and Tomorrow'.
21.09.24
One of the major focus areas for CGF is to develop and test methods for different types of geophysical monitoring of nature and the environment and to create innovative products in service of the community. CGF has been working with Indre Fosen municipality to identify a place that is of social interest to conduct research experiments. In connection with the construction of a new road between Sund and Bradden, we thought it might be valuable to drill some test wells and instrument them with geophysical measuring equipment such as hydrophone cables and FO for DAS.
CGF has previously made geophysical measurements over time in shallow wells, and shown that one can measure tube-wave velocities with quite high accuracy. We want to use the same measurement setup for observation and monitoring of any changes in the subsoil in connection with road construction. The first results are now coming through and show that DAS does indeed detect a multitude of signals of interest!
21.09.22 - New arrivals at CGF!
CGF welcomes several new PhD students to its ranks, following a successful recruiting campaign earlier this year, bringing in fresh young energy and ideas to energise our Work Packages.
First up we have Andrea, a geologist from Brazil who has 
worked in the energy industry in the US, UK and Norway. Andrea has extensive experience in fit-for-purpose reservoir modelling and integrated uncertainty analysis. She developed a keen interest in research and innovation on CO2 storage while working on her Master’s thesis, investigating factors impacting multi-layer plume distributions in CO2 storage reservoirs, followed by involvement in the Northern Lights project while working as a consultant for Equinor in Trondheim. Her research will focus on improving quantification of CO2 migration into the overburden and detection of possible leakage out of the storage complex. Andrea is working with Phil Ringrose in WP 2.
Next we have Franz, a geophysicist with a background in active seismics who became interested in using fibre-optics for seismic monitoring as part of his Master’s thesis. In his PhD work he is interested in registering and monitoring avalanches as well as other geohazard events using Distributed Acoustic Sensing. Franz is working in WP 1.
Kristina studied Applied Physics at Waseda University in Japan, and then graduated with a Masters in Physics at NTNU. Kristina is working on embedding geophysical activity sensors in optical data communication systems. The project aims to develop a sensor that can be integrated into an optical fibre infrastructure that can differentiate geophysical from other activities, such as manufacturing. Using the optical fibre itself as a sensing element could allow us to operate at distances beyond current DAS limitations. Kristina is excited to be working as a PhD candidate at CGF as part of WP1 and is looking forward to contributing to accurate monitoring and forecasting of the Earth.
Finally (for the moment) we welcome Ricardo, a geophysicist with degrees from Universidad Simón Bolívar (USB) in Venezuela and NTNU in Norway. Ricardo is passionate about quantitative seismic interpretation and rock physics, and he has been working for the last 3 years at CGG in the UK, doing both seismic data processing and velocity model building. During his research project, he plans to combine his experience in seismics with plume dynamical models, to improve the detection and monitoring of CO2 injected into a reservoir as part of WP2.

CGF researchers Martin Landrø and Ståle Emil Johansen presented the paper "Using DAS-fibre for lunar seismic imaging" at the European Lunar Symposium 2022 May 24th-26th together with co-authors Nicole Schmitz and Hans Amundsen.
A set of major mission themes has emerged from the 2020 ESA Call for Ideas, "Exploring the Moon with a large European lander", with a polar ice prospecting missjon identified and currently being studied as a candidate EL3 science mission. A combination of Ground-Penetrating Radar (GPR), Magnetic Induction Spectroscopy (MIS) and Distributed Acoustic Sensing (DAS) has been propsed to localize and 3D-map water ice and volatiles in the subsurface. Based on several terrestrial DAS-experiments and the rapid development of high sensitive DAS interrogators, we think there is great potential to use this technology for lunar subsurface exploration.

We had the pleasure of inviting all partners to a half-day discussion and presentation meeting at the CGF offices. The meeting was attended by the following partners: ASN, Equinor, Magseis Fairfield, Bane NOR, Sikt and Shearwater. The purpose of the meeting was two-fold; to create an opportunity for partners to meet and present CGF-related activities to each other and to discuss further areas of mutual interest. A more comprehensive partner meeting will be arranged in October, so there will be more upcoming opportunities for those who could not attend. CGF is also happy to host individual visits from partners at any time.

Steinar Bjørnstad from Tampnet gave an inspiring presentation on the potential for "Using State of Polarisation data from fibre-optical communication systems for monitoring purposes". This is a new DAS technique which does not require the fibre to be dark and which can relatively easily be installed on existing fibres worldwide to provide massively extensive sensing coverage of the Earth's low-frequency activity.
21.03.11 - Webinar on AI in HPC by Prof. Anne Elster
This talk will focus on how AI techniques can be used in the development of HPC environments and tools. As HPC systems become more heterogeneous by adding GPUs and other devices for performance and energy efficiency, they also become more complex to write and optimise the HPC applications for. For example, both CPU and GOUs have several types of memories and caches that codes need to be optimised for. We show how AI techniques can help us pick among 10's of thousands of parameters one ends up needing to optimise for the best possible performance of some given complex applications. Ideas for future opportunities will also be discussed.

PhD + PostDoc positions
The CGF periodically issues invitations to apply for funded PhD positions. Being a strongly interdisciplinary centre, we are looking for entrepreneurial students with a wide variety of interests and backgrounds, from electronic engineering to fibre optics, from geophysics to acoustic wave propagation modellers, from heterogeneous computing to statistical and data scientists. Successful applicants will work at the CGF premises at NTNU in Trondheim as part of our international team of key researchers. The CGF PhD research fellowships are hosted by several departments at NTNU: Computer Science, Electronic Systems, Geoscience and Petroleum and Mathematical Sciences. The Centre has close contact with industry partners as well as research partners NORSAR and Jamstec in Japan.
PhD students will use and develop advanced models and methods for combining diverse geophysical data to effectively monitor the earth. PhD students will be involved in the planning of new surveys and the acquisition of valuable geophysical information to improve forecasts and provide important decision support for the various application domains of the CGF.
The CGF is developing novel methods for the cost-effective use of fibre optic cables, creating Distributed Acoustic Sensing (DAS) systems for Earth monitoring. Such DAS data complement traditional geophysical data sources such as seismic waveform measurements, electromagnetic data, and geomodelling information.
To extract the important variables from massive spatio-temporal geophysical data, the CGF will work on heterogeneous platform computing and AI-based approaches for feature extraction, enabling efficient monitoring and early warning systems in the various geosciences applications.
PhD research work will be led by supervisors with strong scientific profiles in the specific disciplines at the CGF.
The CGF is determined to deliver research-based innovation, and it will strongly stimulate PhD candidates to create and develop innovative ideas into business potential both for the Centre partners as well as in spin-off companies. The key innovation areas of the CGF are in CCS management, hydrocarbon production monitoring and geohazards monitoring and forecasting.
