These data were collected in the Atlantic Ocean at numerous stations in the surf zone in Nov 2016, Jan 2017, Apr 2017, Sep 2017, and Oct 2017. Data were collected with a Sequoia Scientific LISST-ABS acoustic backscatter sensor mounted  on the Coastal Research Amphibious Buggy (CRAB) along with other acoustic and optical sensors. The CRAB occupied numerous stations near the break point in the surf zone on each field day.   Stations were typically occupied for 30 minutes. Data were sampled at 1 Hz continuously while the CRAB was in the water. A .nc file was created for each station.\n";
