WetlandNNI: Quantification of hydrologic interception of nitrogen (National Nutrient Inventory) by conterminous U.S. wetlands (1987-2017)
(DATA/SOFTWARE) [Published : Oct 03, 2025]
Wetland restoration can be an effective tool in nutrient reduction strategies. However, to be effective as a strategy, restored wetlands must be geographically positioned where (1) soil and hydrologic conditions promote wetland persistence post-restoration and (2) interception of...
Biological Condition Gradient (BCG) and Ecosystem Services Gradient (ESG): Companion Tools for Assessing the Condition of Our Aquatic Resources and Valuing Their Benefits
(PRESENTATION) [Presented : Sep 09, 2025]
The Ecosystem Services Gradient (ESG) framework parallels the Biological Condition Gradient (BCG) as a way of visualizing current conditions within the context of the full range of potential biological condition, from highest quality to highly degraded. The steps to building and ...
Air Sensor Data Unifier: R-Shiny Application
(JOURNAL) [Published : Aug 30, 2025]
Data is needed to understand local air quality, reduce exposure, and mitigate the negative impacts on human health. Measuring local air quality often requires a hybrid monitoring approach consisting of the national air monitoring network and one or more networks of air sensors. H...
