Ice Shelf Rift Time-Lapse Photography
Entry ID: macayeal_rifttime-lapse_photography_0229546

Abstract: From November 2004 to March 2005 an automated "web cam" was operated on the southward facing lip of a large ice-shelf rift to produce a photographic record of processes active in ice-shelf rift systems. four times each day, the camera took a photograph in 4 repeating directions. The data here consists of jpeg images (each about 45kbytes).
