Revised and reposted November 18, 2016

In November 2016, tables 1–11 and Appendix 3 tables 3–2 through 3–15 were made available for download from the 
U.S. Geological Survey Science Base Catalog at http://dx.doi.org/10.5066/F7HQ3X18, and downloadable files of 
the tables were removed from the U.S. Geological Survey page in the Publications Warehouse for Data Series 997 
at http://dx.doi.org/10.3133/ds997. The PDF file of Data Series 997 has been revised, so that text on 
pages iv–v, 35, and 55 directs the reader to the tables at http://dx.doi.org/10.5066/F7HQ3X18. In addition, the 
words “version 1.1, November 2016” on the front cover, the title page, the page of publishing information about 
the report, and the back cover indicate this revised release of Data Series 997.
