The analytical laboratories reviewed and the flagged data, corrected a few samples that contained misidentification problems, and commented on the rest of the data. The laboratories verified that most of the data we flagged were analytically correct with "no reasons to doubt the veracity of the data". As analysts, we retained the flags on these data and did not include them in "over-arching" analyses such as trends or summary statistics; however, these data can be used in case studies and other analyses using individual samples. Specific data validation findings are summarized in Appendix A. The tables list the species that were flagged and provide reasons why the data were flagged.
