Research Project: Investigating Factors that Influence Hypoxia and Denitrification in Aquatic Agroecosystems

Location: Water Quality and Ecology Research

Project Number: 6060-13660-009-002-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2017
End Date: Aug 31, 2022

The objective of this cooperative research project is to conduct research on the assessment of microbial processes that improve water quality and mitigate agricultural contaminants from non-point source pollution in aquatic agroecosystems.

Field and laboratory experimentation will be used to assess the influence of environmental drivers on denitrification and hypoxia. Seasonal denitrification and sediment oxygen demand measurements will be made using continuous-flow incubations of sediment cores from different habitats to ascertain nitrogen removal from aquatic agroecosystems. Field experimentation will be used to assess net ecosystem production under manipulated hypoxic conditions.
