    dct:description "This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from 18 Texas reservoirs during August through October, 2016. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with USGS research efforts and publications available to the public. The dataset includes all routine and quality assurance/quality control samples collected at each of the sites. Phytoplankton were identified to the lowest possible taxonomic level and abundance (density reported as both natural units and cells) and biovolume are reported." ;
