LBA-ECO LC-07: Methane and Carbon Dioxide Emissions from Balbina Reservoir

LBA-ECO LC-07 provides flux measurements and concentration data for methane and carbon dioxide from the Balbina Reservoir in the central Amazon Basin. Measurements include gas fluxes from surface waters to the atmosphere, as well as dissolved CH4, CO2, and O2 concentrations in surface and bottom water at 10 to 14 sites. Data collection occurred monthly from April to November 2005, with additional sampling in February 2006, and includes vertical profile data from September 2004 to February 2006.

Use Cases

• Quantifying greenhouse gas emissions from a tropical hydroelectric reservoir based on flux chamber measurements.
• Analyzing seasonal patterns in dissolved methane and carbon dioxide concentrations across multiple reservoir sites.
• Modeling vertical stratification of dissolved gases and temperature in a reservoir water column.
• Assessing the impact of reservoir age and tropical conditions on carbon cycling based on long-term concentration data.

Strengths

• Provides multi-year temporal coverage from July 2004 to February 2006.
• Includes measurements from 10 to 14 distinct sampling sites within the reservoir.
• Contains multiple data types: gas flux, surface water concentration, and vertical profile data.

Limitations

• Column names and exact row counts are not provided in the available metadata.
• Conflicting last-updated dates exist between sources (2006-02-15 vs. 2026-04-10), casting uncertainty on data currency.
• Documentation of sampling and analytical methods is implied but not detailed in the provided descriptions.
