Accelerating Electronic Tag Development for Tracking Free-Ranging Marine Animals at Sea
Abstract:
The work is focused on improving and testing the use and application of existing electronic tags and developing new, more complex hardware and software. For currently available archival and satellite tags we are 1 testing performance and durability, 2 improving light based geolocation estimates using sea surface temperature, 3 determining whether light levels recorded by archival tags can be used to estimate chlorophyll alpha concentrations, 4 examining the use of stomach temperature tags to document feeding behavior, and 5 testing light based geolocation for use on birds. New tag technologies under development include a conductivity, temperature, depth CTD sensors for both archival and satellite tags and a GPS tag. Refine and develop electronic tagging technologies for Tagging of Pacific Pelagics TOPP, a pilot program of the Census of Marine Life CoML. The tags under development will enable the project to address more complex questions about marine predators and their environment and collect high quality environmental data for integration into oceanographic databases.
