Spearman's rank correlations and corresponding P values for relationships between vertical velocity of Ascent 1 (linear ascent) and Ascent 2 (transition point ascent) with respect to environmental variables

Ascent phase vertical velocity	Dive maximum depth	Dive minimum temperature	Dive minimum oxygen
Ascent 1 (n = 289)	r s = 0.6516 P < 2.2 × 10−16	r s = −0.5868 P < 2.2 × 10−16	r s = −0.1858 P = 0.001515
Ascent 2 Segment 1 (n = 224)	r s = 0.7658 P < 2.2 × 10−16	r s = −0.7064 P < 2.2 × 10−16	r s = −0.6125 P < 2.2 × 10−16
Ascent 2 Segment 2 (n = 224)	r s  = 0.4318 P < 1.38 × 10−11	r s  = −0.3134 P < 1.70 × 10−6	r s  = −0.1895 P = 0.0044
