Description: Investigation into the possible origin of these enigmatic wetland depressions scattered across the Eastern U.S. coastal plain from southern New Jersey to northern Florida.
The mosaic of images that began the C-bay-origin debate. The Age and Tropic History of Lake Waccamaw, North Carolina Sediment cores were collected in Lake Waccamaw, a Bay Lake in southeastern North Carolina. The cores were analyzed for information that might be relevant to concerns about the age and trophic status of the lake which is home to several endemic species. Analysis of the diatoms and sponge spicules in the sediments revealed that the lake has always been nearly eutrophic. Analyses of sediment carbon and phosphorus content also support this view. The sediment record indicates that Lake Waccamaw has had periods of shallowing followed by deeper phases. Our interpretation of the geologic history of the Lake Waccamaw area, the sediment record, and the relevant data of others is that Lake Waccamaw is a relatively young lake, probably around 15,000 years old or less. The presence of endemic fauna in the lake is probably a result of the lake's unique chemistry and productivity and not the result of a long period of reproductive isolation from other populations.
