Compounded effects on wetland greenhouse gas fluxes from climate change and water management along a saline to freshwater gradient.

ABSTRACT: Saline and freshwater wetlands store large amounts of carbon, which has driven interest in their role as nature-based climate solutions. Because these ecosystems can be both sinks and sources of carbon to the atmosphere as environmental conditions and human influence change, the net climate mitigation potential of wetlands at regional to global scales remains uncertain. We used a data-driven approach to measure ground-based and airborne fluxes to upscale carbon dioxide (CO₂) and methane (CH₄) fluxes using satellite-based surface reflectances at 500-m resolution across a gradient of saline to freshwater wetlands in Southern Florida, USA. Daily time series of CO₂ and CH₄ fluxes from 2000 to 2024 integrated surface properties related to vegetation p
