Abstract:
The integration of biotelemetry and Slocum electric gliders presents new opportunities and challenges for interpreting the relationship between acoustically telemetered animals and the environment. Slocum gliders are able to stay in the field for extended periods (> 90 days) while collecting high-resolution data that can be used to reconstruct subsurface habitats. Here we present several case studies that compare integrated and externally mounted acoustic receiver technologies aboard Slocum gliders, compare detection efficiency between coastal arrays and Slocum gliders, investigate signal detectability in coastal habitats, and identify habitat associations of migrating species. Our studies leverage several ongoing tagging efforts, and would not be possible without a highly collaborative biotelemetry community. Slocum gliders are a robust technology that augments existing biotelemetry arrays and enable dynamic sampling of environments that extend beyond the feasibility of stationary arrays. The platforms are ideal for integrating biotelemetry into ocean observing and can provide ecologically relevant habitat associations that assist in the management of telemetered species.
