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!

This channel is a series of short films and time lapse photography of coastal Georgia, many of which are of the salt marsh. I named the channel "salt marsh watch" because many of the films are of the expansive, tidal salt marsh wetland, which makes up nearly 1/3 of all the salt marsh found on the east coast of the U.S. If not specifically of the marsh, then they are either about the fate of the salt marsh under sea-level rise, or of lives and livelihoods that are intimately tied to the salt marsh.

I decided to shoot these partially for fun and partially for use in outreach efforts for my PhD research on vulnerability to sea-level rise. Throughout my graduate school time, I'll continue to add new (and hopefully better) pieces, so keep coming back to check them out.
