Table 6. From the 1998, 1999, 2002 and 2004 aerial surveys, for each species group, estimates of (A) g(0)_leading, and (B) ESHW (in meters) and significant covariates; all were derived in the original analyses. The “teams” are the single and leading legs (SL), trailing legs (trail), and duplicates (dup). The covariates are: Beauf = Beaufort sea state, WTemp = sea surface water temperature, Wind = wind speed, Size = group size, Behav = behavior category, Cue = cue category, Depth = bottom depth, ObserverGrp = observer group, Slope = bottom slope, Period = first or second period, None = no covariate found significant.
