SC coast spotlighted in study of marshlands

CHARLESTON, S.C. (AP) - A study of the damage rising sea levels can do to marshlands is focusing on South Carolina tidal creeks.

The Post and Courier of Charleston reported Sunday that researchers from Boston University looked at the Cape Romain National Wildlife Refuge for their study.

Along Horsehead Creek east of McClellanville, the winding tidal creeks have turned into straight rushing rivers eroding sediment - the area marsh grasses need to grow.

As those grasses disappear, more ocean water floods in the area filling it with creek instead of marsh.

Salt marshes act as nurseries for sea life providing safe havens and feeding for shrimp and other creatures in their infancy. The marshes also act as a filter to keep waters clean.

South Carolina has about 400,000 acres of coastal marshes.
