Ardmucknish Bay on the Scottish west coast was the site of a controlled sub-seabed CO2 release experiment from May to October 2012. The study deployed three pCO2 sensor technologies alongside instruments measuring oxygen, temperature, salinity, and currents to monitor leakage. Researchers used a multivariate statistical approach to distinguish natural forcing from CO2 release signals.
Use Cases
- Compare pCO2 measurements from fluorescence, NDIR, and ISFET-based sensors to evaluate performance under controlled leakage conditions.
- Analyze correlations between pCO2 and O2 variations to identify periods dominated by natural forcing versus CO2 release influence.
- Model localized CO2 impact using high-frequency parallel measurements from instruments placed within 1 meter of each other.
- Assess spatial heterogeneity of seafloor CO2 emissions using 2D horizontal mapping data from release and control sites.
Strengths
- Data includes parallel high-frequency measurements from multiple co-located instruments for validation.
- Experiment recorded peak pCO2 values up to ~1250 µatm at the release epicenter.
- Study combines in-situ sensor data with a hydrodynamic circulation model calibrated for background conditions.
Limitations
- Dataset scope is limited to a single six-month experiment at one location, reducing generalizability.
- Specific data structure, row count, column names, and file formats are unknown from the provided description.
- Temporal coverage is from 2012, and the data may not reflect current sensor technologies or conditions.
