Short Biography

Greg Noe has been an ecologist with the U.S. Geological Survey's National Research Program in Reston, VA since 2002. Dr. Noe’s research centers on wetland ecosystem ecology, focusing on the interactive influences of geomorphology, hydrology, climate, and biology on nitrogen and phosphorus biogeochemistry in fluvial ecosystems, as well as plant community ecology and restoration ecology. His dissertation research identified the complex controls on annual plant germination in the salt marshes of southern California. This was followed by post-doctoral research on phosphorus biogeochemistry and enrichment effects in the Florida Everglades. When joining the USGS, he started a research program on nutrient cycling, transport, and retention in wetlands associated with flowing waters. This work includes quantifying nutrient retention by riverine floodplains from site to watershed scales with study sites located in Maryland, Virginia, Pennsylvania, West Virginia, North Carolina, and Louisiana; the effect of sea level rise and salinification on tidal freshwater forested wetland ecosystem resilience in Virginia, South Carolina, and Georgia; phosphorus and sediment transport research in the Florida Everglades; and studies of nutrient dynamics and trapping in created mitigation bank wetlands located in Virginia and stream restoration projects in North Carolina. He is currently serving on the editorial board of Wetlands and previously of Wetlands Ecology and Management, is the past Chair of the South Atlantic Chapter of the Society of Wetland Scientists, the recipient of the President's Service Award from the Society of Wetland Scientists, and has served on the program committees of national and international scientific conferences.

Wetland Ecosystem Ecology and Biogeochemistry

Image of Current Focus for Wetland Ecosystem Ecology and Biogeochemistry

My research is motivated by the need to understand the fundamental controls on how wetlands influence water quality.

I quantify the interactive influences of geomorphology, hydrology, climate, and biology on nitrogen, phosphorus, and carbon biogeochemistry in fluvial ecosystems, as well as plant community ecology and restoration ecology.


Current focus areas:

How floodplains retain nitrogen, phosphorus, and sediment loads in the watershed of the Chesapeake Bay

Models to predict wetland water quality functions

The response of tidal freshwater swamps to sea level rise

Optimizing the design of created and restored wetlands to improve their functioning

The influence of flow on phosphorus and sediment transport and cycling in the Everglades
