Count Component Title Abstract
1 Water Column Sonar Data Collection The collection and analysis of water column sonar data is a relatively new avenue of research into the marine environment. Primary uses include assessing biological abundance, species identification,and habitat characterization. It is also useful for evaluating underwater gas seeps, characterizing the seafloor and bathymetry. The NGCD is collection and archiving of this data from a number of sources including the NOAA and academic fleets, and making the data available to researchers and the public around the world.

          1 The primary data in this collection consists of raw instrument files that were submitted to NGDC for archive. in addition, ancillary files such as water column profile data are also included. these files were submitted to NGDC through hard drive delivery, R2R or ftp. When possible, checksum values are compared to verify file integrity before being added to the archive. No other processing or quality control steps are applied ot data.
