Previous studies

Seismic acquisition for geothermal energy near Storvorde, Jutland

Acquisition of 80 km of 2D seismic data along eight profiles near Storvorde, northern Jutland. We used a single 16.5 tonnes vibroseis truck as the source and 1200 wireless nodes laid out at 10 meter interval. The target depth was 4-5 km, to image the deep subsurface prior to the drilling of a geothermal well in Storvorde.

The acquisition was carried out during March and April 2026 with assitance from geoscience students from the universities in Aalborg, Aarhus and Copenhagen.

Moen klit

Imaging the glaciotectonic complex at Møn, Denmark

Active and passive seismic acquisition at Møn, Denmark, to image the impressive glaciotectonic complex which raises up to 128 above sea level along the coast.

We collected a 2.5 km seismic profile in May 2025, using one of our vibroseis trucks as source. In addition, we did passive listening with 300 nodes distributed in the terrain for ambient noise tomography.

The seismic study is part of a larger project on landslides in Denmark and aims to understand how the glaciatectonic structures influence the landslide processes at Møn.  

Seismic truck

Vibroseis at Lesbos, Greece

In October 2024, we provided the vibroseis source for 25 km 2D profiles for an evaluation of the potential for geothermal energy in the island of Lesbos.

The project was done in collaboration with the research institutions National Technical University of Athens (NTUA), National & Kapodistrian University of Athens (NKUA) and the Swedish Uppsala University.

Test of equipment at Stenlille, Denmark

Upon receipt of new land seismic equipment in 2024, we did a small seismic acquisition at the Stenlille gas storage site, Denmark, to test the data quality.

Two 2.5 km profiles were acquired in a cross-spread configuation using wireless nodes with MEMS (micro-electrical-mechanical system) sensors laid out with 10 meter intervals, and a single 16.5 tonnes vibroseis truck as source. The data were subsequently processed in-house and described in this brief report.

Boat on ice

Marine seismic acqusitions west of Svalbard

As part of the GoNorth 2024 expedition, 724 km of seismic reflection data were acquired in the ice-infested waters of Fram Strait onboard the Norwegian icebreaker Kronprins Haakon.

Seismic adquisition

Marine seismic acqusitions in fjords of West Greenland

Collaboration with University of Texas to quantify the effect of moraine building on Greenland tidewater glaciers onboard the Irish research vessel Celtic Explorer in 2024.

Marine seismic acqusitions in the Baltic Sea

GEUS supported several marine seismic acqusitions of the Swedish Geological Survey (SGU) for CCS related studies in 2023 and 2025.

Marine seismic equipment

Marine seismic acqusitions in the North Sea

In April 2023, 1450 km of seismic reflection data were acquired across the Jammerbugt structure for CCS purposes onboard the Faroese research vessel Jakúp Sverri in collaboration with Federal Institute for Geosciences and Natural Resources (BGR) in Germany.

Bridging the marine gap between islands of Sjælland and Nekselø

In 2022, as part of the CCS related study of the Havnsø structure, marine receivers (ocean bottom seismometers and a hydrophone cable at the seafloor) were used to record Vibroseis signals to bridge the 2-km wide marine gap.

Stenlille

Monitoring for micro earthquakes at Stenlille

Monitoring for micro earthquakes at the Stenlille underground gas storage facility, Denmark, to investigate the effect of pumping large amounts of gas into the subsurface. Data from 2018–2020 was screened for microseismicity, but no events above the estimated detection level of ML 0.0 were detected within the Stenlille gas storage.

Imaging the glaciotectonic complex at Møn, Denmark

Active and passive seismic acquisition at Møn, Denmark, to image the impressive glaciotectonic complex which raises up to 128 above sea level along the coast.

We collected a 2.5 km seismic profile in May 2025, using one of our vibroseis trucks as source. In addition, we did passive listening with 300 nodes distributed in the terrain for ambient noise tomography.

The seismic study is part of a larger project on landslides in Denmark and aims to understand how the glaciatectonic structures influence the landslide processes at Møn.
