Ecological parameter reductions, environmental regimes, and characteristic process diagram of carbon dioxide fluxes in coastal salt marshes.

ABSTRACT: We investigated the ecological parameter reductions (termed "similitudes") and characteristic patterns of the net uptake fluxes of carbon dioxide (CO₂) in coastal salt marshes using dimensional analysis method from fluid mechanics and hydraulic engineering. Data collected during May-October, 2013 from four salt marshes in Waquoit Bay and adjacent estuary, Massachusetts, USA were utilized to evaluate the theoretically-derived dimensionless flux and various ecological driver numbers. Two meaningful dimensionless groups were discovered as the light use efficiency number (LUE = CO₂ normalized by photosynthetically active radiation) and the biogeochemical number (combination of soil temperature, porewater salinity, and atmospheric pressure). A semi-logarithmic plot of the
