BOREAS TF-11: Water Surface Film Effects on Fen Greenhouse Gas Fluxes

1994 and 1996 field measurements quantify the effect of surface films on carbon dioxide and methane transfer from water to air at the SSA Fen site. The BOREAS TF-11 team used chamber flux methods with a gas chromatograph and LI-COR LI-6200 to calculate gas fluxes. This data complements tower flux measurements for understanding carbon dynamics in a boreal wetland.

Use Cases

• Modeling surface film impacts on gas transfer velocities based on chamber flux measurements.
• Analyzing seasonal or interannual variability in CO2 and methane emissions from boreal fens.
• Calibrating or validating tower-based eddy covariance flux estimates with chamber method data.
• Studying the role of physical barriers (films) in wetland-atmosphere greenhouse gas exchange.

Strengths

• Data collected during two distinct field campaigns (1994 and 1996), providing temporal context.
• Produced by a recognized research organization (NASA) as part of the large-scale BOREAS project.
• Cross-platform presence (Data.gov and NASA Earthdata) signals established scientific use.

Limitations

• Column names and precise row counts are not provided in any source, hindering structural assessment.
• Sources conflict on 'last updated' date (1996 vs. 2026), indicating potential metadata inconsistency.
• Documentation is described but not directly accessible; data formats include non-standard types (ISO, BIN).
