Comparison of mean bleaching variance described by DHW versus DHW-V ^ at NWHI locations. REA obs and TOW obs in the upper panel indicate observations from the rapid ecological assessments at fixed transects and towed-diver benthic survey video analysis, respectively; Obs in the lower panel represents mean of all observations of all methods at each location. Predictions based on regression of DHW are given with dashed lines. Predictions based on regression of DHW and fifth root of lagoon and backreef volume (V"^) are given with solid lines. Table 2. Variance, F-, and p-statistics for the regression analysis of mean bleaching observations for each reef in the NWHI from Necker to Kure. REA and TOW indicate observations from the rapid ecological assessments at fixed transects and towed-diver benthic survey video analysis, respectively; mean represents mean of all observations of all methods at each location. The upper portion is regression statistics using DHW alone; the lower is multiple regression of DHW and the fifth root of lagoon and backreef volume, as explained in the text.
