    dct:description """The goal of this study was to complete a comprehensive evaluation of a low-dose copper treatment for zebra mussel (Dreissena polymorpha Pallas 1771) suppression. The treatment objective was to maintain an average copper concentration of 60 µg/L in waters above the thermocline for 10 consecutive days. The study was conducted in Lake Minnetonka (Hennepin County, Minnesota) and the copper treatment was applied to St. Albans Bay (66.3-ha). Robinson Bay (37.2-ha) was used as an untreated control reference site. Five locations were identified as sampling sites throughout each bay and marked with a buoy. Test animals were held, and samples were collected in the vicinity of these sampling buoys before, during, and after treatment. 
The datasets included are as follows:
Alkalinity and Hardness
Benthic Invertebrate Sampling Results
Biotic Ligand Model Data
Chlorophyll A
Copper Data
Mortality
SCUBA Zebra Mussel Survey
Secchi Disk and Light Intensity Data
Test Animal Condition Data
Thermocline Data
Tissue Copper Residue Summary
Water Chemistry
Zebra Mussel Settlement
Zooplankton Sampling Summary""" ;
