Characterization of postdive recovery using sound recordings and its relationship to dive duration, exertion, and foraging effort of southern elephant seals ( Mirounga leonina)
Abstract It is notoriously difficult to measure physiological parameters in cryptic free‐ranging marine mammals. However, it is critical to understand how marine mammals manage their energy expenditure and their diving behavior in environments where the predation risks are low and where survival is...

Abstract It is notoriously difficult to measure physiological parameters in cryptic free‐ranging marine mammals.
