Article Performance Comparison of Argos and Iridium Tracking Technologies for Sea Turtle Movement Ecology Studies(MDPI, 2025-12-15) Casale, Paolo; Figgener, Christine; Arendt, Michael; Broderick, Annette C.; Ceriani, Simona A.; Kaska, Yakup; Plotkin, Pamela; Luschi, PaoloSatellite tracking has dramatically improved research on wide-ranging large marine vertebrates such as sea turtles. Traditionally, sea turtle tracking has relied on Argos-based satellite telemetry tags, which estimate location via Doppler shift and can also transmit sensor data. GPS-equipped Argos satellite tags represented a significant evolution, offering higher location accuracy. More recently, GPS-equipped satellite tags transmitting via the Iridium satellite network have become available for sea turtle tracking, and this study aims to assess whether they offer additional advantages. The performance of three satellite tag types-Argos-only, Argos-GPS, and Iridium-GPS (Iridium)-was assessed using data on 116,074 positions from 48 sea turtles representing five species and multiple ocean basins. Performance was evaluated using three indicators: the proportion of days with location data, the duration of gaps between locations, and the number of positions per day. Bayesian generalized linear mixed models assessed the effect of satellite tag type, technical settings, species, and activity (migration, foraging, internesting). Results indicate that Iridium satellite tags generally perform similarly to both Argos-based satellite tags, but performance improves significantly when programmed with high-frequency GPS acquisition (>24 positions/day), a result made possible by their tenfold higher transmission capacity compared to Argos. This capacity also enables transmission of more sensor data. Performance, however, varied by species and activity. These findings highlight the potential of Iridium tags to enhance fine-scale movement studies by improving the spatial and temporal resolution of sea turtle tracking, with important implications for ecological research and conservation planning.Conference Object Increasing nesting activity of loggerhead turtles (caretta caretta) on Dalyan Beach, Turkey during 2008-2014 nesting seasons: an encouraging trend(2015) Kaska, Yakup; Sezgin, Çisem; Secme, Mücahit; Sarı, Fikret; Başkale, Eyüp; Sözbilen, Doğan; Ulubeli, Sevay Ayşe; Düşen, Serdar; Mutlu, Doğukan; Eryiğit, Ahmet; Ergun, GunerConference Object Are Nesting Loggerhead Turtles Changing Their Reproductive Schedules on Dalyan Iztuzu Beach, Turkey?
