Table 4 Mean change in depth for non-exposure and exposure dive inversions

Seal	Mean change in depth for non-exposure inversions (m)		Mean change in depth for exposure inversions (m)		Anderson–Darling k-sample test
G5449	14.875 (±13.997)	n = 283	70.5	n = 1	n/a
G6110	16.749 (±16.293)	n = 8	186	n = 1	n/a
G6651	24.867 (±39.981)	n = 30	96.36 (±59.23)	n = 7	p = <0.001

Dive inversions are defined by a change from ascending to descending >3 m over 4 s, for all dives deeper than 100 m. Standard deviation is given in parentheses, and n is given for each. Results from an Anderson–Darling k-sample test comparing the change in depth of an inversion from ascending to descending, normalized by maximum depth of dive, for exposure inversions of seal G6651 to non-exposure inversions from seal G5449 (n = 283) are given
