USGS Science Center: USGS water resources and biological research offices are usually divided by state and are called science centers. You can find a list and descriptions of science centers on the USGS home page at http://water.usgs.gov/.
Project: Each biological community sample in BioData belongs to one and only one project. Typically data collected for a single Project has consistent objectives, design, and methods.
NAWQA study unit: In the beginning cycles of the National Water Quality Assessment Program (NAWQA), the United States was divided into river basins, or study units, in order to collect consistent data on a watershed scale across the country. Some of the study units may cross state boundaries. For additional information and further descriptions of NAWQA study units refer to http://water.usgs.gov/nawqa/nawqamap.html.

USGS Science Center provides a 'starts with' search box to help limit the list of options
Project provides a 'contains' search box that REQUIRES (see below) at least 2 characters to view a list
NAWQA Study Unit also provides an optional 'contains' search box; if used, it still requires two characters
