Chimney Pole Marsh Erosion-Camera Images and Video 2009-2012

This data consists of a time series of image and video files showing erosion at the western edge of Chimney Pole Marsh, in Northampton Co. Virginia. Images depict the edge of a salt marsh as it erodes. Images and videos have a time stamp (YYYYmmdd_HHMMss) embedded in their file name and also in the upper left of the images themselves. All dates and times are in Eastern Standard Time. Images and videos are taken once ever 30 minutes at 25 and 55 minutes after the hour. Still image JPEG (.jpg) files are 1600x1200 pixels in size. Videos are encoded as MPEG-4 (.mp4) files with a resolution of 400x304 at 8.05 frames per second. They were collected by a 2 mega-pixel Vivotek IP7161 security camera attached to a post (approximately 3-m above the marsh surface). The camera was removed when the marsh was sufficiently eroded that the camera platform was imperiled. There are some gaps in the data caused by network and electrical problems.
