Blue carbon ecosystems—tidal marshes, mangroves and seagrasses—are hotspots of carbon sequestration in oceans.
Though there is a great deal of interest in how rising CO2 and nitrogen impact ecosystems together, very few long-term field studies have manipulated both.
The first experiment on the marsh, and the longest-running of its kind in the world, began in 1987 under the guidance of plant physiologist Bert Drake.
The Global Change Research Wetland is dedicated to unraveling the complex ecological processes that confer stability on coastal marshes as they respond to global environmental change.
Since the 1960s, a non-native lineage of the common reed, Phragmites australis (commonly called Phragmites), has been taking over wetlands across North America.
Warming and elevated CO2 experiment in the Global Change Research Wetland. Heat lamps warm the plants from above, while cables heat the soil.
Methane (CH4) is a powerful greenhouse gas. Wetlands rank among the world’s largest methane emitters.
