Climate Change Experiment Fast-Forwards the Chesapeake Bay to the Year 2100 [News article and audio]
The Biogeochemistry Lab studies element cycles to understand how ecosystems respond to global-scale changes such as sea level rise, warming, elevated carbon dioxide, nitrogen pollution and invasive species.
Our holistic approach integrates the responses of both plants and microbes, the two dominant life forms regulating the capture and release of energy in organic compounds.
We operate the Smithsonian's Global Change Research Wetland, and NSF-LTREB facility dedicated to unraveling the complex ecological processes that confer stability on coastal marshes as they respond to global environmental change. Other research themes include methane emissions from wetlands and upland forests, and carbon sequestration in blue carbon ecosystems.
Research investigates wetland plant response to rising carbon dioxide levels;in Nature Climate Change
A recent study, based on experiments at the Global Change Research Wetland, suggests that morphological responses to carbon dioxide and nitrogen supply by Schoenoplectus americanus influences the capacity of marshes to gain elevation at rates that keep pace with rising sea levels. Sam Illingworth composed a wonderful poem inspired by the article on The Poetry of Science.
SERC and international collaborators publish on wetland carbon storage in Nature
The Biogeochemistry lab's Patrick Megonigal and James Holmquist were co-authors on a recent global synthesis of carbon storage in coastal wetlands. They demonstrate that wetlands experiencing rapid sea level rise store more carbon than wetlands under stable sea level conditions, suggesting a mitigation effect coastal wetlands have on global environmental change.
