QICS Data: 2D Seismic Reflection from Controlled CO2 Release in Ardmucknish Bay

2D high-resolution seismic reflection data were collected before, during, and after a controlled injection of CO2 into shallow marine sediments in Ardmucknish Bay, Oban, in 2012 and 2014. The dataset was collected by the National Oceanography Centre Southampton and the British Geological Survey under the NERC-funded QICS program to monitor gas migration. It includes SEGY files, a results presentation, and a map of post-release seismic data extent.

Use Cases

• Track the spatial and temporal evolution of free gas anomalies based on repeated seismic surveys.
• Investigate changes in sediment acoustic properties like reflectivity and attenuation based on CO2 presence.
• Model gas migration pathways and controlling mechanisms in unconsolidated marine sediments.

Strengths

• Data covers multiple time points: pre-release (15/05/2012), syn-release (six days in May-June 2012), and post-release (two days in April 2014).
• Project is linked to a peer-reviewed publication (Cevatoglu et al., 2015) with a DOI.
• Data collection involved major research institutions: National Oceanography Centre Southampton and the British Geological Survey.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The post-release data is currently restricted, limiting full temporal analysis.
• Row count and dataset size are unknown, which may limit suitability assessment.
