Figure 5.

The expired air temperature of exhaled air as a function of ambient temperature, as measured in a northern elephant seal (blue circle markers) (22), a grey seal (blue triangle markers) (15), and computed by the present model using geometric data from Eb (bearded seal) (orange markers). Lines were fitted to experimental and modeled data by linear regression, giving $0.6T_{\text{amb}}+12.7$ (blue solid line), $0.46T_{\text{amb}}+24.5$ (blue dashed line), and $0.42T_{\text{amb}}+16.7$ (orange line), respectively.
