Areas of Specialization
  • Ecological effects of environmental stressors

  • Improving the science supporting numeric nutrient criteria development
  • Phytoplankton production and bloom dynamics
  • Coastal oceanographic processes
Current Research
  • Nutrient Management for Sustainability of Aquatic Ecosystems: Building a Locally Applicable Management Tool Box for Application across the U.S. - This task is centered on the need to develop standardized approaches and solutions to assist States with moving from narrative to numeric nutrient criteria. A significant portion in this task is focused on coastal receiving waters with the objective to improve the ability to protect water quality and designated uses in downstream estuarine/coastal receiving waters. The task will also initiate coordinated research on freshwater systems and will develop approaches to protect designated uses in these water bodies. The longer term aim to develop decision support tools for sustainable nutrient management that addresses the environmental, economic and social/human health aspects of sustainability.
  • Modeling the Linkage Between Discharge and Nutrients from the Mississippi River Basin to Gulf of Mexico Hypoxia - This task will develop a modeling framework for predicting how nutrient management decisions and future climate change scenarios will impact the size, frequency, and duration of the low oxygen (i.e., hypoxia) area that forms every summer on the continental shelf of the northern Gulf of Mexico. The modeling framework includes a northern Gulf coastal ocean model and a Mississippi River Basin model. The coastal ocean models consist of state-of-the-art linked hydrodynamic (EPACOM), eutrophication (GEM and GoMDOM), and nutrient air deposition (CMAQ) models. The Mississippi River Basin model will link a suite of coupled atmospheric models to an existing watershed and water quality model such as SWAT, LSPC, NEWS, or SPARROW.
