Example data records for dive profile and pitch.

<p>Dive profile with gliding and stroking periods are indicated in green and blue, respectively. Red circles indicate feeding events. Examples are taken from an adult male during (a) early feeding season (Mn11_H607_1; tissue density = 1037.0 kg m^-1) and (b) late feeding season (Mn11_H607_2; 1031.2 kg m^-1), (c) a pregnant female (Mn11_H002; 1026.5 kg m^-1) and (d) a calf (Mn10_139a; 1040.8 kg m^-1).</p

Relationship between gliding patterns and relative tissue density.

<p>The y-axis indicates differences in the percentage of time spent gliding during ascent and descent phases of non-feeding dives by each whale. Vertical and horizontal error bars show standard deviation and 95% credible interval range, respectively. A relative tissue density of >1 indicates that tissue density was denser than surrounding seawater.</p

The number of 5-s sub-glides in relation to tag duration and 95% CI range.

<p>Number of 5-s sub-glides that could be used for the hydrodynamic glide model in relation to tag duration (a) and the range of 95% credible interval for tissue density estimates (b). Magenta circles and blue crosses indicate data from Gulf of St Lawrence and Antarctica, respectively. A solid line shows a regression line: log(y) = -0.0062x + 0.90.</p

Tissue density estimates from the best model with the lowest DIC.

<p>The top panel shows posterior distribution of individual body tissue density for each tag deployment. Blue and magenta lines indicate whales from Antarctica and the Gulf of St Lawrence, respectively. Box plots in the bottom panel show median and interquartile range of tissue density estimates from each location.</p

Prior and posterior distributions from the model with lowest DIC (Table 3).

<p>Prior and posterior distributions of tissue density (a, b, c), drag term (d, e, f) and diving gas volume (g, h, i) are shown in each panel. Solid green and black lines indicate the prior and posterior distributions, respectively. Dashed green lines show the estimated global distribution that can be interpreted as the population distribution for that parameter. The left and middle panels show global parameters (a, b, d, e, g, h) and the right parameters show individual and dive-specific parameters.</p
