Appendix C. Mean and variation in environmental variables among sites in each region.

Table C1. Mean (A) and variation (B) in environmental variables among sites in each region. Environmental variables include dissolved oxygen (DO), temperature (T), salinity (Sal), and relative chlorophyll levels (CHL). Data from the 12-month sampling are shown. Variation is expressed as the coefficient of variation, CV. Variation among racks within a site was negligible and variation among sites (shown) did not consistently vary with latitude.
