What one marsh tells us about rising CO2

Posted by KristenM on October 27th, 2009

In the world of unassuming marshes, the Kirkpatrick Marsh stands apart. Smithsonian plant physiologist Bert Drake has studied this wetland for more than two decades. It’s located in Maryland, along the Rhode River, a sub-estuary of the Chesapeake Bay. Drake and his colleagues have used this community of grasses and sedges to explore whether plants have the potential to become a carbon source or a carbon sink. Watch the audio slideshow below, for a tour of the field experiment.

You can read more about Drake’s experiment on the Smithsonian Environmental Research Center’s Web site.
