  • Title: Plant-mediated methane transport in emergent and floating-leaved species of a temperate freshwater mineral-soil wetland
  • Methane flux from freshwater mineral-soil (FWMS) wetlands and its variability among sites is largely modulated by plant-mediated transport. However, plant-mediated transport processes are rarely resolved in land surface models and are poorly parametr (read full)

  • Title: Outgoing Near-Infrared Radiation From Vegetation Scales With Canopy Photosynthesis Across a Spectrum of Function, Structure, Physiological Capacity, and Weather
  • We test the relationship between canopy photosynthesis and reflected near-infrared radiation from vegetation across a range of functional (photosynthetic pathway and capacity) and structural conditions (leaf area index, fraction of green and dead lea (read full)

  • Title: Long-term carbon flux and balance in managed and natural coastal forested wetlands of the Southeastern USA
  • Wetlands store large C stocks and play important roles in biogeochemical C cycling. However, the effects of environmental and anthropogenic pressures on C dynamics in lower coastal plain forested wetlands in southern U.S. are not well understood. We (read full)

  • Title: Paired CH4 concentration and stable isotope measurements identify concentration spikes and source attribution at a hydraulic fracturing field in West Virginia
  • Hydraulic fracturing (hydrofracking) for natural gas has increased rapidly in the area of the Marcellus Shale in the last thirty years and estimates of CH4 emissions from hydrofracking operations are still uncertain. Previous studies on CH4 emissions (read full)

  • Title: Carbon sequestration and biodiversity co-benefits of preserving forests in the western United States.
  • Forest carbon sequestration via forest preservation can be a viable climate change mitigation strategy. We identify forests in the western conterminous United States with high potential carbon sequestration and low vulnerability to future drought and (read full)

  • Title: From NEON field sites to data portal: a community resource for surface–atmosphere research comes online
  • The National Ecological Observatory Network (NEON) is a multidecadal and continental-scale observatory with sites across the United States. Having entered its operational phase in 2018, NEON data products, software, and services become available to f (read full)

  • Title: Atmospheric measurements of the terrestrial O2 : CO2 exchange ratio of a midlatitude forest
  • Measurements of atmospheric O2 have been used to quantify large-scale fluxes of carbon between the oceans, atmosphere and land since 1992 (Keeling and Shertz, 1992). With time, datasets have grown and estimates of fluxes have become more precise, but (read full)

  • Title: The eddy-covariance storage term in air: consistent community resources improve flux measurement reliability
  • In the widely-used eddy-covariance (EC) technique, it is often assumed that the air storage term, i.e. the change of below-turbulence-sensor scalar abundance, is negligible or comprises a small part of net surface-atmosphere exchange (NSAE). Previous (read full)

  • Title: Disentangling the effects of temperature and substrate availability on soil CO2 efflux
  • Soil respiration (Rs), the largest carbon emission flux in ecosystems is usually modelled as an empirically parameterized function of temperature (Ts), and sometimes water availability (Ɵ). The likely contribution by other factors, such as carbohydr (read full)
