Diatom counts were entered into the North American Diatom Ecological Database (NADED) at the ANS. Original data were recorded on paper forms or stored electronically on computer floppy disks. The taxa included in each count were reviewed carefully, and were changed when necessary to make them consistent with taxonomic nomenclature used at the ANS during the mid1980s. In many cases this required the additional effort of examining original slides and making partial recounts of some slides. The number of diatom valves or cells counted varied among samples, ranging relatively evenly from about 100 to 2500.

3), shows that hardness, pH, alkalinity and chloride explain more of the variability among samples than any other factors at the scale of the eastern US (Table 4). These variables correlate most strongly with the first axis. SRP, turbidity and Si correlate most closely with the second axis. Temperature and turbidity are most closely associated with the third axis. The chemistry variables included in the analysis were the 16 significant variables in the forward selection analysis described above, but excluding Ca and Mg because they had a high VIF (>20).
