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

BOREAS TF-11 team data quantifies the effect of surface films on carbon dioxide and methane transfer from water to air at the SSA Fen site. Measurements were made in 1994 and 1996 using the chamber flux method, with concentrations analyzed by gas chromatograph and a LI-COR LI-6200. This dataset complements tower flux measurements for the Boreal Ecosystem-Atmosphere Study.

Use Cases

• Modeling surface film impacts on gas exchange coefficients based on chamber flux measurements.
• Analyzing seasonal or interannual variability of CO2 and CH4 fluxes from a boreal fen.
• Validating tower-based eddy covariance flux measurements with ground-truth chamber data.
• Studying the role of abiotic surface conditions in wetland methane emissions.

Strengths

• Data collection is part of the large, well-documented BOREAS campaign, lending credibility.
• Covers two field seasons (1994 and 1996), allowing for temporal comparison.
• Uses established measurement methods (chamber flux, gas chromatograph, LI-COR LI-6200).

Limitations

• Critical metadata conflicts: 'last updated' dates differ drastically (1996 vs. 2026) across platforms.
• Column names and row counts are unknown, limiting immediate usability.
• Documentation is sparse, with no author specified and incomplete size information.
