The intent of these data is to make single-beam bathymetry, subbottom profiles, magnetic, gravity, side-scan sonar and historic seismic reflection and refraction data available to the public for a wide variety of uses such as research and Earth Science analysis. These data are not intended to be used for navigation. Nautical charts produced and certified by NOAA should be used for navigational purposes.
