Abstract:
The number of scientific papers resulting from biologging instruments deployed on marine mammals is increasing
as improved technologies result in smaller devices and improved sensor-, storage- and transmission capabilities.
I undertook a comprehensive review of papers resulting from biologging deployments on free-ranging marine
mammals between 1965 and 2013 (n = 620) to summarise where (e.g. on which species, as well as in which
geographic areas) deployment efforts were focused, the impacts of the resulting papers, and where there are
shortcomings in the literature. Species-, sex- and age-class biases were evident in terms of animals instrumented.
Also, large proportions of the papers resulted from deployments on a small number of species (particularly among
the pinnipeds) and were more often on adult females than other demographic classes. The mean impact of papers
(as assessed using journal impact factors and numbers of citations) was consistent over time, and was influenced
by the number of species studied, sample sizes and instrument capabilities. I found a paucity of papers addressing
device influences on animals, as well as studies with explicit conservation and/or management implications. This
review aims to increase awareness of marine mammal biologging data already collected, stimulate appropriate
further studies, and encourage the reuse of existing data.
