Broadband acoustic backscattering measurements from the Connecticut River

These data included broadband echosounder data measured as part of the ONR Under Sea Remote Sensing (USRS) project. These observations data
acquired around the ebb plume from of the Connecticut River using a downward-looking pole mounted system and a Remus 100 vehicle. The downward-looking, pole samples were recorded during transects with R/V Dawn Treader, which was equipped with Simrad ES70-7C and ES120-7C split beam transducers. The Remus 100 vehicle was equipped with upward-looking echosounders (Simrad model ES200-7CDK split beam and ES333-7CDK single beam) operated in an upward looking configuration from a REMUS 100. All measurements are associated with transects of the ebb plume front and are dominated by scattering from bubbles entrained in the vicinity of the front and scattering from turbulent mixing and stratification at the base of the river plume.
