Large datasets of greenhouse gas and energy surface-atmosphere fluxes measured with the eddy-covariance technique (e.g., FLUXNET2015, AmeriFlux BASE) are widely used to benchmark models and remote-sensing products. This study addresses one of the major challenges facing model-data integration: To what spatial extent do flux measurements …

Biophysical Drivers Of Net Ecosystem And Methane Exchange Across Phenological Phases In A Tidal Salt Marsh
Vázquez-Lule, A., Vargas, R.

Salt marshes are large carbon reservoirs as part of blue carbon ecosystems. Unfortunately, there is limited information about the net ecosystem (NEE) and methane (CH4) exchange between salt marshes and the atmosphere to fully understand their carbon dynamics. We tested the influence of biophysical drivers by plant phenological phases …

Linking Vegetation Spectral Reflectance With Ecosystem Carbon Phenology In A Temperate Salt Marsh
Hill, A. C., Vázquez-Lule, A., Vargas, R.

Salt marshes constitute an important terrestrial-aquatic interface that remains underrepresented in Earth System Models due to constraining biophysical controls and spatially limited land cover. One promising approach to improve representativeness is the application of proximal remote sensing to generate phenological information, …

Tidal Wetland Gross Primary Production Across The Continental United States, 2000–2019
Feagin, R. A., Forbrich, I., Huff, T. P., Barr, J. G., Ruiz‐Plancarte, J., Fuentes, J. D., Najjar, R. G., Vargas, R., Vázquez‐Lule, A., Windham‐Myers, L., Kroeger, K. D., Ward, E. J., Moore, G.

L., Bergamaschi, B., King, J. S., Miao, G.

We mapped tidal wetland gross primary production (GPP) with unprecedented detail for multiple wetland types across the continental United States (CONUS) at 16‐day intervals for the years 2000–2019. To accomplish this task, we developed the spatially explicit Blue Carbon (BC) model, which combined tidal wetland cover and field‐based …

Carbon Dioxide And Methane Emissions From A Temperate Salt Marsh Tidal Creek
Trifunovic, B., Vázquez‐Lule, A., Capooci, M., Seyfferth, A. L., Moffat, C., Vargas, R.

Coastal salt marshes store large amounts of carbon but the magnitude and patterns of greenhouse gas (GHG; i.e., carbon dioxide (CO2) and methane (CH4)) fluxes are unclear. Information about GHG fluxes from these ecosystems comes from studies of sediments or at the ecosystem‐scale (eddy covariance) but fluxes from tidal creeks are …

Experimental Influence Of Storm-Surge Salinity On Soil Greenhouse Gas Emissions From A Tidal Salt Marsh
Capooci, M., Barba, J., Seyfferth, A. L., Vargas, R.

Storm surges can substantially alter the water level and salinity in tidal salt marshes. Little is known about how changes experienced during storm surges affect greenhouse gas emissions (GHG; CO2, CH4, N2O) from tidal salt marsh soils. Understanding how storm surges influence ecosystem processes is critical for evaluating the ecosystem’s …
