Rising seas clearly evident along South Carolina coast
Living in a coastal town or city with seawalls and docks on the waterfront, it can be difficult to notice the sea level rise by increments each year. But effects of higher sea level are very clear down a winding dirt road in Georgetown County where acres of what was once a forested wetland have morphed into a salt marsh of dead trees jutting toward the sky.
"When you go into the field, you really see a lot of trees dying. That's the first thing that catches your eye," said Alex Chow, who teaches biosystems engineering at Clemson University's Baruch Institute of Coastal Ecology and Forest Science located at Hobcaw Barony, a 17,500-acre wildlife refuge northeast of Georgetown.
Chow and two other colleagues at the institute used aerial photos to map how the salt water has advanced into freshwater Strawberry Swamp from nearby Winyah Bay. Their study found that over the past six decades, the amount of salt marsh in the area has increased from about 4 acres to more than 16 acres. The study was published in December in "Wetland Science and Practice," the quarterly journal of the international Society of Wetland Scientists.
"Over long periods — and what we looked at is over 60 years — the maritime forest retreats at approximately the same rate sea level rises," said Tom Williams, a professor emeritus of forestry and natural resources who is a co-author.
