This shapefile represents the trackline along which seismic profile data collected aboard the R/V RAFAEL during USGS field activities 05001 and 06001 in Apalachicola Bay and St. George Sound, Florida. The seismic data that were collected from the R/V RAFAEL were acquired differently in 2005 than in 2006. During the first seven survey days of the 2005 field season (Julian days 076-083) a Knudsen 320 b chirp profiler (3.5-12 kHz) was used and during the remaining part of the 2005 season a towed Edgetech FSSB 424 (2-24 kHz) system was used. In 2006, the Edgetech FSSB 424 was used for the entire field season, but it was mounted on a pole rather than being towed on a cable. In 2005 both the Knudsen and Edgetech seismic data were logged in SEG-Y format using Delph Seismic +. In 2006 the Edgetech seismic data were logged in SEG-Y format using SBLogger. The purpose of these data is to manage the filenames and geographic locations of seismic profile images that are hyperlinked to each trackline.
