|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
