Introduction: Episode 2: At the Water's Edge: The Salt Marsh (03:28)

FREE PREVIEW

Salt marshes stretch for miles before reaching the sea. They function as nursery grounds for various species, a buffer during storms, and a filtration system; change is constant. Scientists study salt marshes and seek to understand their response to climate change.

U.S. Southern East Coast (05:17)

Georgia has approximately 350,000 acres of salt marsh; most of its barrier islands remain undeveloped. Experts study the marsh, including plant productivity and invertebrate numbers, to understand long-term change. Smooth cordgrass is the dominant grass species.

Sapelo Island (05:07)

Scientists study salt marsh productivity; they use high-tech instruments to study the movement of carbon. Salt marshes, mangroves, and seagrass beds can vary carbon at higher rates than upland forests. Researchers investigate above and below ground biomass.

Tybee Island (02:28)

Rising sea levels pose a threat to humans living on the edges of salt marshes. Scientists work with city officials to protect the backside of the island from flooding. They examine a sediment core sample.

Florida Salt Marsh (09:26)

Scientists study various fish that spend time in the marsh, including the saltmarsh topminnow and alligator gar. Pensacola Bay has five genetically distinct groups of topminnow. Scientists use acoustic tags to obtain gar population and spawning information; receivers also provide information on Gulf sturgeon.

Description

Along scenic coastlines in the South, waves of mesmerizing green and golden grass stretch to the horizon. This is the salt marsh - a part liquid, part solid landscape that is teeming with life. How do scientists study the salt marsh? And how resilient is it to climate change?
