Robin has accepted a post doc position at CGF, where we welcome his continued contributions.

Kit is moving back to Bangkok, Thailand to work as a geophysicist in the Subsurface Technical Solutions Division of PTT Exploration and Production Plc. (PTTEP).


CGF are delighted to celebrate Prof. Lasse Amundsen, a CGF board member, Adjunct Professor at NTNU and senior leader at Equinor, being presented with the Reginald Fessenden Award by the SEG at their meeting in Houston, Texas on 29th August for his extensive contributions to exploration geophysics over many years.  Lasse Amundsen is well known for his work in seabed seismic acquisition and in a variety of areas in seismic and electromagnetic data processing and analysis.  He coauthored SEG's Introduction to Petroleum Seismology, second edition in 2018.  In addition, he coauthored, along with our Director, Martin Landrø, Bivrost's Introduction to Exploration Geophysics in 2018 and From Arrhenius to CO2 Storage in 2023.


Robin Rørstadbotnen, one of our talented PhD students, was recently invited by EAGE to record an E-Lecture for its educational portal, Learning Geoscience.  The invitation recognises Robin as a distinguished lecturer following his presentation at the EAGE Annual 2022 in Madrid, where his paper 'Analysis of a Local Earthquake in the Arctic Using a 120 KM Long Fibre-Optic Cable´ was presented. It was rated as one of the best rated talks at the event and was selected by the EAGE Education Committee.  Robin's e-Lecture can be accessed at Analysis of a Local Earthquake in the Arctic using a 120 km long Fibre-Optic Cable (


Professor Philip Ringrose (CGF WP leader on CO2 and gas/energy storage) has won the SINTEF and NTNU CCS Award 2023. He received the award during the conference dinner at the 12th Trondheim CCS Conference (TCCS-12). 

Building on a solid scientific background as a geoscientist, Philip has specialised in applying his knowledge of the subsurface to CO2 storage, and has worked directly on several large-scale storage projects, such as Sleipner, Snøhvit and In Salah. He currently works as a specialist in geoscience at Equinor and an adjunct professor of CO2 storage at NTNU.  On receiving the award, Philip declared “I’m really honoured, it’s really humbling to receive such a reward, thank you very much, it is a team effort and I’m really proud to be part of this huge team.”  He chairs the Scientific Committee in the Norwegian CCS Research Centre (NCCS), and has been influential in establishing the CO2 DataShare project, which is an open digital portal for sharing data from international CCS projects.

TCCS is a non-profit, leading scientific conference that focuses on the research and development of CCS. Its objective is to advance, present and discuss the latest work in the field undertaken by R&D institutions, universities and industry. TCCS takes place every other year in Trondheim, Norway.


It is wonderful to see one of our papers in Geophysics is currently the top-featured publication for May/June 2023 on the SEG library webpage.  The paper is on DAS sensing of storms and other low-frequency features, with lead author Kittinat Taweesintananon.



John Potter delivered a keynote presentation at the Oceanoise 2023 conference in Vilanova i la Geltrú, Spain on the potential for DAS to monitor whales and ships.  John subsequently participated in the conference closing discussion panel, which decided to draft an urgent call to governments and operators worldwide to address the growing problem of noise in the ocean.  This call to action was released on 8th June, World Ocean Day.


One of our talented PhD students, Kristina Shizuka Yamase Skarvang, was recently awarded ´Best Poster Presentation´ for her paper entitled "Comparing Sensitivity of State of Polarization Monitoring and Distributed Acoustic Sensing in the Svalbard Arctic Submarine Communication Cable" at the SubOptic 2023 conference in Bangkok.  SubOptic is a triennial event for the submarine cable industry and this year was focussed on ´Collaborating on our Critical Infrastructure´.  

23.03.20 - CGF supervised student wins Best Masters' Thesis award

The winner of the best Masters' thesis in Electronic Systems at NTNU for 2022 was Martin Ericsson with the thesis "Fish-farm Integrated Sensor Cluster: Environmental and Biological Surveillance in Fish-farming Aquaculture with Emphasis on Sensor Fusion". While Martin is not part of CGF, he was supervised by John Potter and the technological focus is of considerable interest, fusing optical and acoustic sensing with AI interpretation.  His award has been written up (in Norwegian) in the elektronikknett magazine.

23.03.10 - GeoExPro article on global data sharing

An article in GeoExPro on global data sharing has been published, featuring Phil Ringrose, our WP leader on CO2 storage.  The article  announces the CO2 DataShare online portal, an initiative by the international CO2 Storage Data Consortium, with the goal to make available curated and well-documented datasets from CO2 storage projects. So far, the portal has seen 28,000 downloads from a wealth of different countries.  This is an important development in CO2 storage capability development and sharing and CGF is pleased to see this portal become available.

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
high-performance computing framework for preprocessing large datasets related to high-resolution geophysical monitoring, combining his mathematical modelling background with his high-performance computing experience.


Our Research Director, Prof. Jo Eidsvik, is featured in the European Consortium for Mathematics in Industry (ECMI) blog today!


One of our CGF students, Robin Rørstadbotnen, has been invited to record his EAGE presentation made at the annual EAGE conference in Madrid in 2022 as an e-lecture.  His presentation was one of the best-rated at the conference and also selected by the EAGE Education Committee.


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.


`Inside Telecom´ has recently published (in Norwegian) an article about CGF DAS research and how it could be used to monitor and protect cables, a service already offered by a CGF partner.  The piece is entitled (translated) `NTNU researchers will soon be able to ensure that submarine cables monitor themselves even around the clock.  New technology means that the cables themselves signal when vessels are approaching.´. The article is behind a paywall but can be seen at

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 (

The Svalbard Post (


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.  


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!


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.

21.11.01 - Visit by MEP Markus Pieper

CGF was pleased to host a visit of Dr. Markus Pieper, Member of the European Parliament for Germany, on Monday 1st November. Dr. Pieper was visiting Trondheim as a part of a visit hosted by Equinor to present an overview of R&D on CCS, renewables and low-carbon hydrogen. Professor Philip Ringrose and Professor Martin Landrø presented an overview of C02 storage research with a focus on emerging geophysical methods, including the latest findings in fibre-optic sensing, that can support future expansion of CCS in a low-emissions society. 

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. 




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'.




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.

Happy Constitution Day Norway!  


On 13th December CGF convened at 'To Rom og Kjøkken' in downtown Trondheim for a wonderful 'Julebord'.  There was time to reflect on a year's hard work and achievements, celebrate in the good company of friends and colleagues, laugh over a playful 'Kahoot' quiz (thanks Helene!), tell a tall story or two and, perhaps the highlight of the evening, to enjoy an informal recital by our very own Kristina Skarvang, who played a traditional Norwegian fiddle, the "Hardingfele" in Norwegian, or "Hardanger fiddle" in English.  Kristina played two pieces:"Rotnheimsknut, Halling" and "Kongstunen, Rudl", both greatly appreciated in the warm and cosy environment.


On the 18th October CGF hosted a site visit from the Norwegian Research Council (NRC).  This is the first time the SFI-team from NRC has been able to visit CGF.  CGF Director Martin Landrø and the leadership team spent 3 hours with the NRC visiting delegation, presenting the Centre and leading visits to some of our laboratory facilities and offices.  

The NRC team comprised Liv Jorunn Jenssen (leader), Tarjei Malme and Pål Sigurd Malm.  Two CGF commercial partners were also invited to give presentations; Espen Raknes from AkerBP and Olaf Schjelderup from Sikt.  Thomas Tybell, Head of the Electronics Systems Department (IES) gave an overview of IES and the role IES plays in supporting the CGF.  The discussions were very positive and CGF received valuable feedback, which will later be summarised in a report, including recommendations for future directions. 









The CGF convened its first all-member workshop at the Scandic Nidelven hotel in Trondheim from 5-7 October, bringing engagement from partners, both research and commercial, to connect with NTNU researchers and each other over an intensive 3-day event.  The first two days were spent in discovery, with partners and NTNU PhD researchers interleaving short presentations, with ample discussion time, coffee breaks and wonderful buffet lunches, for which the Scandic Nidelven is famous.  Day 3 featured a series of working sessions, including Main, Research and Innovation Advisory Board meetings, together with group working sessions on ideas for what to change, what to keep, what to start afresh at CGF.  The workshop was completed with distillation and focus sessions, into which was injected some exciting new perspectives, harvesting the best and most valued ideas generated during our joint work.  CGF senior management now has some work on its hands to gather the products of this workshop, issue summary reports, and take action on the items that were identified!


The CGF ran a course on the geology and geophysics of CO2 storage in Spanish Pyrenees. The course was run by Philip Ringrose (NTNU, IGP/CGF) and Allard Martinius (TU Delft - Civil Engineering and Geosciences) 22-27th August in and around Ainsa in the foothills of the Pyrenees in Spain. 

The focus was on understanding deltaic and fluvial sedimentary deposition and their influence on CO2 storage processes. The group also looked at the nature of caprocks, faults and fractures in the context of CO2 storage. The course blended field-site visits to outcrop sites with invited evening lectures on fluid dynamics, geophysics, geomechanics and sedimentology, providing a valuable training and team-building event for CGF PhDs and staff.

Professor Martin Landrø held the course "Geophysical Monitoring of CO2 Storage" on the last day of the third EAGE Workshop on Marine Acquisition arranged in Oslo 22-24 August. See the full program here.


Professor Anne Elster gave a Distinguished Lecture at the University of Bergen, entitled "Parallel Computing and AI: Impact and Opportunities". The lecture focused on adapting to developing technologies in the field and the potential to develop better algorithms and techniques to solve problems in the field for HPC. 


Philip Ringrose and colleagues in WP2 in CGF gave a keynote talk on "Monitoring challenges for CO2 storage: interplay of fluid dynamics with 4D seismic response" at the SEG summer workshop: Toward Gigatonnes CO2 Storage Grand Geophysical Challenge.

This was part of a four-day workshop at the University of Stanford, California, focused on the subsurface challenges of large-scale geological sequestration and how geophysical methods can provide solutions to these challenges. Half the participants attended in person and half were online. As well as reviewing the latest work on CO2 storage, the workshop included brainstorming sessions on "hot topics" for CCS-related research. The summary of these discussions will be shared with the applied geophysics community as a basis for broader discussions in the years to come. 


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. 



The EAGE Annual Conference 2022 will be taking place in Madrid June 6th-9th. We are pleased to announce that several of CGF's associated PhDs will be presenting at the conference, covering the following topics:

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.

The CGF was pleased to host Tone Holm-Trudeng, Director of Renewables, and Fons ten Kroode, Chief Geophysicist, from our partner Magseis Fairfield for a site visit to the CGF on Gløshaugen campus in Trondheim.  An initial introduction and orientation to the CGF and some of the Centre’s facilities expanded into an impromptu presentation by Fons on Full Wave Inversion techniques that was well-received by research staff and students, with interest to apply this innovative iterative approach to modelling DAS seismic data.


CGF is delighted to welcome Helene Alnes Vedlog to her new full-time role as Coordinator of the CGF.  Helene first came to us on a ‘temporary attachment’ of a few weeks in March 2021, but was very quickly enticed to continue working with the CGF part-time, shared with the IES administrative office. We are now very happy that Helene has accepted the position of full-time coordinator and look forward to working with her for many years to come.  Helene comes to us with a degree in Psychology and a Masters’ in Organisational Psychology, so is unusually well-qualified for building bridges across our pool of academics and industry partners.


After more than a year of tumultuous growth and development, we are both sad to say goodbye to Liv Elin Sandnes as our coordinator, but also delighted to congratulate her on taking up her new role as Organisation and Communications manager at the Museum of South Trøndelag (Museene i Sør-Trøndelag – MiST).  Liv Elin was instrumental in overcoming many of the initial teething troubles of setting up the new Centre and managing the many liaison tasks with our partners.  All at CGF wish Liv Elin the very best in her new role.

CGF-researcher and head of research at NORSAR, Volker Oye, has been interviewed by NRK about the earthquake risk in connection to a huge new road construction work in Rogaland, Norway. The current plans involve the construction of the longest underwater tunnel in the world. Read more here



Prof. Anne Elster, an IEEE CS Distinguished Visitor Program Speaker, will be giving a talk to IEEE Computer Society's largest chapter (12,000+ members) entitled "AI for High Performance Computing: Experiences and Opportunities" tonight at 6pm PST, which is 3am here in Norway!  The talk will focus on how AI techniques can be used in the development of the HPC environment and tools.


Prof. Potter delivered the inaugual seminar of the Distinguished Lecture Series on Cutting Edge Technologies for Underwater Communications, invited by the Technology Innovation Institute (TII) Autonomous Robotics Research Center (ARRC) of the United Arab Emirates (UAE).  The TII is a brand new cutting-edge scientific research centre based in the UAE under the umbrella of the Advanced Technology Research Council of Abu Dhabi.


Volker Oye from Norsar is presenting an invited talk at the Oslo SEG meeting on the Energy Transition today entitled "Passive Seismic Monitoring of CO2 Storage Sites".





Every year, NTNU runs a public outreach and education event called 'Researchers' Night'.  This is an important dissemination event that brings together students and teachers from upper secondary schools and high schools in Trøndelag.  This presented an excellent opportunity for CGF to connect with young minds and communicate our research.  A CGF team designed, prepared and delivered a multi-media stand activity that included video, hands-on props, posters and a Kahoot competition on the subject of 'Listen to the Ocean', featuring FO DAS results and in-situ acoustic/video whale tags.  The stand attracted many groups of students over three hours of display time and we even got a request for our preprint DAS paper from one student, who thought it should be published in Nature!


The chronicle article by Philip Ringrose and Martin Landrø is sparking a spirited debate!  A reply to one of the commentaries on the article was published today by Martin Landrø, thanking Tore Torp for a post that we mainly agree with. Assessing what is expensive and not in connection with the capture and storage of CO₂ is demanding and Tore Torp is absolutely right in that it is possible to see this from a different point of view. We emphasise that capture and storage is not a "quick fix" with industrial companies queuing up to get involved.


Prof. Anne Elster gave an invited talk to the ScalPerf´21 meeting in Bertinoro, Italy entitled "From Norwegian Computing & IBM to Benchmarking Challenges & Autotuning"


Prof. Phil Ringrose gave an invited Keynote talk entitled “A Global Perspective on the CO2 Storage Potential for Africa” at the PESGB/HGS Africa E&P Conference (14-15 September 2021), an event co-sponsored by one of our Partners, Shearwater.

This was followed by a technical talk given by his PhD student Oscar Nhabanga (based on his PhD thesis work) entitled: “Shale Depth Functions for the Rovuma Basin Compared with Other Offshore Basins as a basis for Estimation of Ch4 and CO2 Containment Systems.”  

Oscar is now at the Eduardo Mondlane University, in Mozambique (having completed his PhD at NTNU) and was awarded 'Best Overseas presentation' at the Conference.

21.09.14 - Chronicle article on CO2 storage by Landrø and Ringrose

As part of our public science outreach, two leading CGF professors (Martin Landrø and Philip Ringrose) recently published a chronicle article on the feasibility of CO2 capture and storage.  The title points out that "Carbon capture and storage is too expensive, too uncertain, but is it still possible?"  As the energy transition gathers place, the interest in this subject is growing.  10 years ago the authors started teaching CO2 storage subjects at NTNU.  At that time there were approximately 8-10 students who took the subject. This year there are over 30 students.  The article has stimulated several thoughtful responses, some claiming that the prospect for carbon capture and storage is too faciful to be practical, others saying that the article is too conservative and under-estimates the impact of this technology area in our future.


Our oceans are critical to the health of our planet and its inhabitants.  Increasing pressures on our marine environment are triggering an urgent need for continuous and comprehensive monitoring of the oceans and stressors, including anthropogenic activity. 

A team from CGF has just published a pre-print entitled "Sensing whales, storms, ships and earthquakes using an Arctic fibre-optic cable" describing recent results from a DAS experiment carried out using an interrogator from ASN on a Fibre-Optic (FO) cable offshore Svalbard owned by Uninett.  For the first time, whales have been detected and can be localised using DAS.  Ships are evident, and can be located within an rms error of 50m, compared to AIS 'ground truth'.  There are also many exciting results from both local and distant seismic events and storms over 10,000 km distant, showing that DAS is capable of detecting and discriminating pressure, interface and compressional waves, including separating diving waves that interact with different layers of the earth's mantle.  The large distance that the authors were able to probe down the FO cable (over 120 km) opens the door to the creation of a global atmosphere-ocean-earth monitoring observatory network.


An IEEE OES distinguisehd lecture was delivered by Prof. John Potter in collaboration with IEEE Oceanic Engineering Society through the Italian and Norwegian chapters on 23 July 2021 entitled "Fusion reactors, Fuel Cells, and Distributed Acoustic Sensing - What do they have in common and what might DAS now offer?"  The lecture was given both in person at the University of Pisa and simultaneously online.


Prof. Potter was invited to give a plenary presentation at the Chinese Ocean Acoustics conference on 15th July, entitled "The best way to predict the future is to invent it - Some emerging game-changers in marine sensing".  The lecture was delivered remotely to a live audience in China.


We are delighted to announce that a CGF paper entitled "Source level and vocalizing depth estimation of two blue whale subspecies in the western Indian Ocean from single sensor observations" has published in JASA today.  The paper is a detailed examination of Ocean Bottom Seismometer data from a single hydrophone, showing how this can be used to investigate the range, sources levels and vocalisaion depths of two sub-species of blue whale in the Indian Ocean.

21.05.24 - Anne Elster's Keynote

Prof. Anne Elster gave a keynote talk at the Mobile Intelligent and Ubiquitous Computing Conference, on May 26th 2021, entitled "Parallel Computing and AI- Impact and Opportunities".

21.04.08 - Presentation on using polarisation data from FO network

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.
