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 ECOBB3 optical backscatter sensor mounted on the Coastal Research Amphibious Buggy (CRAB) along with other acoustic sensors. The ECOBB3 measured optical backscatter at 470 nm, 532, nm, and 700 nm. 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 2 Hz continuously while the CRAB was in the water. A .nc file was created for each station.\n"; :history = "USACE/FRF"; :source = "In situ observations from BB3_Crabmmddyy.mat"; :sourceUrl = "(local files)"; :standard_name_vocabulary = "CFv25"; :Metadata_Conventions = "Unidata Dataset Discovery v1.0, CF-1.6"; :metadata_link = "N/A"; :Conventions = "CF-1.6"; :creator_name = "USACE/CHL/COAB"; :creator_url = "http://www.frf.usace.army.mil/"; :creator_email = "frfwebmaster@usace.army.mil"; :license = "These data may be redistributed and used without restriction.
