The ORNL DAAC is pleased to announce the release of a new dataset associated with The North American Carbon Program (NACP) by Wardrup, J., et al (2021):
This dataset provides estimates of soil organic carbon (SOC) in tidal wetlands for the northeastern United States. The data cover the period 1998-2018. Northeastern U.S. tidal wetlands and bordering areas were harmonized from government agencies; U.S. Department of Agriculture - Natural Resources Conservation Service (USDA-NRCS), National Cooperative Soil Survey (NCSS), USDA-NRCS - Rapid Carbon Assessment (RaCA), U.S. Environmental Protection Agency - National Wetland Condition and Assessment (EPA-NWCA), and published studies. Point data for carbon stocks at four soil depths are included. SOC for the four depths was predicted for eight regional zones using regression models driven by environmental covariates. A Random Forest (RF) Ranger method and a Quantile Regression Forest (QRF) model were used to estimate parameters. Predictions and uncertainties are available at a 3 m resolution.
The North American Carbon Program (NACP) is a multi-disciplinary research program designed to obtain scientific understanding of North America's carbon sources and sinks and of the changes in carbon stocks needed to meet societal concerns, and to provide tools for decision makers. NACP began in 2002 and continues to date. The NACP data collection contains continental carbon budgets, dynamics, processes, and management of the sources and sinks of carbon dioxide, methane, and carbon monoxide in North America and in adjacent ocean regions.
Additional data from NACP and other relevant links can be found on the ORNL DAAC's NACP Project Page.
