Inferring cetacean population densities from the absolute dynamic topography of the ocean in a hierarchical Bayesian framework. [PDF]

open access: yesPLoS ONE, 2015
We inferred the population densities of blue whales (Balaenoptera musculus) and short-beaked common dolphins (Delphinus delphis) in the Northeast Pacific Ocean as functions of the water-column's physical structure by implementing hierarchical models in a
