These data were collected in the Atlantic Ocean at numerous stations in the surf zone on Nov 18, 2016. Data were collected with a WetLabs ECONTU optical backscatter sensor mounted  on the Coastal Research Amphibious Buggy (CRAB) along with other acoustic 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";
