Metadata for the BBS provides specific information on the analysis programs and summary information. Metadata on digitized maps and route paths are described here. These data sets are designed to provide public access to analysis results from BBS data. A statement regarding the elements of the website, and a general discussion of the methods, is available at http://www.mbr-pwrc.usgs.gov/bbs/bbs.html. Analysis of survey data can be controversial, and any user of the information should recognize that alternative approaches exist. These programs provide results based on methods that have been accepted in the published literature for many years, but also provide alternative approaches to analysis. Users also have access to actual data from the survey, at http://www.pwrc.usgs.gov/bbs/. Standard disclaimers for use of information are also provided http://www.mbr-pwrc.usgs.gov/bbs/disclaim.html. Information regarding the function of individual elements of the website are available throughout the site, and include help files.
