A quick "snapshot" of the tidal flow in a Georgia salt marsh replete with smooth cordgrass (Spartina alterniflora) and marsh fiddler crabs (Uca sp.) scurrying about over the mud. Location is a few miles north of Darien, GA off of Buzzard Roost Creek. This captures about one quarter of a full tidal cycle. Georgia has semi-diurnal tides, meaning that there are two high tides everyday occurring about 12.5 hours apart.
I shot this as a series of photographs over a period of about three hours (166 minutes) at ten second intervals using a GoPro Hero3 Black Edition mounted to a tripod that I stuck in the mud. I stitched the nearly 6 GB of photos into this time lapse video at 30 frames per second in GoPro's Cineform Studio. I used a dock to access the site. Due to the short battery life, I had to replace the battery twice during the three hours. This meant carefully replacing the battery over the rising water. The second time, the water was only a few inches below the camera case. Precarious!
