Key controls on carbon budgets in stormwater ponds

This reasoning chain connects how different physical zones (littoral vegetation, open water, forebay) and external drivers (land use, meteorology, seasonality) determine differences in greenhouse gas fluxes and overall carbon budget of urban stormwater ponds.
