Researchers from GEOMAR, Ocean Networks Canada, and the University of Victoria have launched a geophysical survey expedition off the Canadian Pacific coast. The team is gathering essential subsurface data to support the development of future carbon dioxide storage monitoring systems.
Why it matters
The survey provides the foundational geophysical data necessary to ensure the reliability and safety of future underground carbon dioxide storage sites. Establishing this baseline is a critical step toward implementing permanent, long-term monitoring systems.
The expedition uses 12 Ocean Bottom Electromagnetic (OBEM) stations to measure electrical resistance in basalt formations. The team utilizes a CAGEM transmitter to send signals along profiles in two distinct directions to account for measurement uncertainty.
The players
GEOMAR
This is a leading marine research institution based in Germany that specializes in ocean and climate science.
Ocean Networks Canada
This organization operates world-leading ocean observatories to collect real-time data from the Pacific, Atlantic, and Arctic coasts.
University of Victoria
This public research university located in British Columbia is a key partner in Canadian marine and geological studies.
The details
Operating from the research vessel SONNE, the team is mapping subsurface basalt formations to determine their suitability for carbon sequestration. These results will inform the engineering design for a future, permanently installed geophysical monitoring network.
Timeline
October 3, 2026: Expedition SO321-3 departed from Vancouver.
October 5, 2026: Geophysical survey operations commenced on the seabed.
October 13, 2026: The expedition is scheduled to conclude in San Diego.
The Big Picture
This project follows the rigorous baseline monitoring protocols established under the SO321-3 expedition framework. By validating these geophysical methods now, researchers are setting a new standard for the technical requirements of industrial-scale carbon storage.
Developing these baseline monitoring systems could eventually lower the costs and risks associated with industrial-scale carbon capture technology. Reliable monitoring ensures that sequestered carbon remains securely stored, potentially accelerating the transition to lower-carbon energy solutions.
The takeaway
Reliable sequestration requires detailed subsurface mapping to ensure long-term site integrity and safety. These geophysical methods represent the essential first steps in verifying that carbon storage is both viable and secure.
