    dct:description """An Innerspace 456 single-beam echosounder in conjunction with a Trimble® differential Global Positioning 
System (DGPS), HYPACK® navigation software, and Ashtech Z-Xtreme and Trimble® R8 Global Navigation 
Satellite System (GNSS) receivers was used to survey 7 chutes and 3 backwaters on the Missouri River 
yearly from 2011-13. These chutes and backwaters are located on the Missouri River between Newcastle, 
Nebraska and Rulo, Nebraska in the States of Nebraska, Iowa, and Missouri.  Surveys of chutes consisted 
of topographic and bathymetric data collected along transects spaced 30.48 m apart from high bank to high 
bank.  Surveys of backwaters consisted of topographic and bathymetric data collected along a transect grid 
of 76.2 m spacing. The data were collected by the U.S. Geological Survey in cooperation with the U.S. Army 
Corps of Engineers (USACE) Omaha District as part of the Missouri River Habitat Assessment and Monitoring 
Program.""" ;
