Water Column Sonar Data Collection

browse graphicImage of water column sonar data collected on the NOAA ship Okeanos Explorer
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 goals of this collection are to archive water column sonar data collected on NOAA, academic and international fleets, and to make the data available to researchers and the public around the world.

Processing Steps
  • 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.
