Pop-up satellite tags (PSATs) can be effectively utilized to study aquatic animals, and their usage has been increasing in recent decades. After releasing tagged study animals, PSATs record and ultimately transmit various time-stamped data measurements (e.g., light levels, pressure, temperature, acceleration, etc.) via the ARGOS satellite system to end users. This technology has allowed researchers to answer important behavioral and ecological questions over various spatio-temporal scales in freshwater, estuarine and marine habitats. Utilized in numerous studies globally, and applied to a diverse and expanding array of species, researchers must continually adapt to overcome emerging challenges unique to the operational constraints of a particular study. This symposium is intended to provide a platform for researchers to share their PSAT experiences, with the goal of discussing encountered challenges and applied solutions that will ideally benefit and inform ongoing and future PSAT projects. Presentation and discussion on experimental design, capture methods, tagging techniques and attachment mechanisms, data auditing, geolocation techniques, analysis, presentation, and results interpretation including evaluation of tag retention and data return rates are encouraged. Promoting a greater understanding of these and other challenges associated with the utilization of PSATs through the collective experience of participating Symposium researchers will directly benefit new and future users of this technology.
