Table 4. Coefficient of determination and model significance comparison between the full, forecast, and year-removal validation models.

	Full Model		Forecast Model		Year Removal Validation		Ratio: Forecast to Full Model
	R2	P-value	R2	P-value	R2	P-value
Humpback Arrival (n = 24)	0.662	P<0.001	0.458	P<0.001	0.471	P<0.001	0.599
Humpback Departure (n = 24)	0.681	P<0.001	0.681 No variables removed	P<0.001	0.588	P<0.001	1.0
Blue Arrival (n = 23)	0.770	P<0.001	0.263	P<0.050	0.574	P<0.001	0.342
Gray-North Departure	0.701	P<0.001	0.290	P<0.050	0.579	P<0.001	0.414
