La Romaine Project: Methane Emissions from Young Boreal Reservoirs, 2015-2022

Data from 2015 to 2022 for three young boreal hydroelectric reservoirs in Quebec, Canada, measuring CH4 diffusive, ebullitive, and degassing emissions, CH4 concentration in water, environmental variables, and carbon isotopic signatures. The dataset was created by Maia Barbosa, Pedro to perform a complete methane mass balance and estimate ecosystem CH4 production, a process rarely measured in aquatic systems.

Use Cases

• Modeling methane mass balance in hydroelectric reservoirs based on measured diffusive, ebullitive, and degassing emissions.
• Estimating ecosystem methane production in aquatic systems based on the complete mass balance approach described.
• Analyzing relationships between methane emissions and environmental variables measured at the reservoir sites.
• Studying carbon isotopic signatures to trace methane sources and processes in boreal reservoirs.

Strengths

• Multi-year temporal coverage from 2015 to 2022.
• Includes multiple measurement types for methane emissions (diffusive, ebullitive, degassing) and supporting environmental variables.
• Focuses on a specific, complex process (ecosystem CH4 production) rarely measured in aquatic systems.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
