These data are JPEG files of seismic reflection profiles (collected in 2006; published by Twichell and others, 2007) that are adjacent to vibracores collected by the U.S. Geological Survey during a 2007 cruise within Apalachicola Bay, Florida. These data are included to give the vibracores greater stratigraphic context. JPEG format is universal and yields an easily browseable pictorial view of the seismic profiles. Each profile image is hotlinked to its corresponding trackline navigation contained within a polyline shapefile (Seismic_Cores_INT.shp). These images also have representations of vibracore locations, which show the calculated core penetration depth on the profile. Core depth was determined by assuming a constant speed of sound in sediment and seawater of 1500 m/sec.
