Pearson’s correlation coefficients for relationships between combinations of different running means and thresholds for mean ODBA (light colours) and VeDBA (dark colours) with ${s\dot{\mathrm{V}}O}_2$ (ml min⁻¹ kg⁻¹; A–C) and for total ODBA (light colours) and VeDBA (dark colours) with sVO₂ (ml kg⁻¹; D–F). Data presented separately for (A and D) large females diving (N = 4 animals; n = 130 trials); (B and E) male fur seals and sea lions swimming transitionally (N = 5 animals; n = 86); C and F female and juvenile fur seals and sea lions swimming transitionally (N = 4 animals; n = 47 trials).
