    dct:description """Hydrographic survey data were collected from May 22 through 
June 10, 2015, using an acoustic Doppler current profiler (ADCP) 
coupled with an RTK-GNSS rover. The collected hydrographic data 
consisted of three elements—riverbed elevations derived from 
bathymetry, depth-averaged streamflow velocity, and instantaneous 
discharge measurements. Hydrographic data were collected as the 
boat moved across the river at planned cross sections distributed 
throughout the reach. Data collection software integrated and stored 
the depth and velocity data from the ADCP and the horizontal and 
vertical positioning data from the GNSS data in real time. Data 
processing required computer software to extract bathymetry and 
velocity data from the raw ADCP and GNSS files and to summarize 
and map the information. Streamflow was measured to document 
the streamflow of the river at the time of the survey, and the variation 
of streamflow around Grande do Pecado Island.""" ;
