We are pleased to announce the publication of the following article
regarding the development of a new multi-sensor suction-cup biologger for
small cetaceans.

Pearson HC, Jones PW, Srinivasan M, Lundquist D, Pearson CJ, Stockin KA,
and Machovsky-Capuska GE (2017) Testing and deployment of C-VISS
(cetacean-borne video camera and integrated sensor system) on wild
dolphins. Marine Biology 164:42. doi:10.1007/s00227-017-3079-z

Abstract:
Multi-sensor biologgers are a powerful method for studying individual
behaviors of free-ranging species, yet the challenges of attaching
non-invasive biologgers to agile, fast-moving marine species have
prohibited application of this technique to small (<5 m) cetaceans.
Integration of video cameras into such biologgers is critical to
understanding behavior from the animal’s perspective; however, this
technique has not been applied to small cetaceans. We examined the
feasibility of remotely deploying a cetacean-borne video camera and
integrated sensor system (“C-VISS”) on small cetaceans. We deployed C-VISS
on eight free-swimming dusky dolphins (Lagenorhynchus obscurus) off New
Zealand (42°25′15″S 173°40′23″E) from December 2015 to January 2016,
collecting a total of 535 min of video footage (average = 66.8 ± 91.10 SD,
range 9–284). Dolphins were observed to show limited reactions to biologger
attachment attempts and deployments. Social and environmental parameters
derived from video footage include conspecific body condition, mother-calf
spatial positioning, affiliative behavior, sexual behavior, sociability,
prey, and habitat type. The ability to record behavioral states and
fine-scale events from the individual’s perspective will yield new insights
into the behavior, socioecology, conservation, rehabilitation, and welfare
of small cetaceans.
