Reef manta ray state-space modelled satellite tracking data

This dataset contains state-space modelled satellite tracking data for reef manta rays (Mobula alfredi) used in Trevail et al. (in press), Journal of Applied Ecology. Between 2015 and 2024, 23 manta rays (12 adults, 8 juveniles, 5 unknown maturity) were tracked within their foraging grounds using towed Argos satellite tags (5 SPOT-253C, 8 SPOT-253G, 10 SPLASH10-F Fastloc®, Wildlife Computers). To correct location errors and regularise positions in raw Argos position estimates, a 5- and 6-hour time step hierarchical Bayesian state-space model (hDCRW) was applied using the bsam R package with MCMC sampling via JAGS (Jonsen et al., 2013).本数据集包含用于Trevail等人即将发表于《应用生态学杂志》（Journal of Applied Ecology）的研究的礁蝠鲼（Mobula alfredi）状态空间模型卫星追踪数据。2015至2024年间，研究人员在23头礁蝠鲼（其中成体12头、幼体8头、成熟状态未知5头）的觅食场域内，使用拖拽式Argos卫星标签开展追踪工作，所用标签包括5台SPOT-253C、8台SPOT-253G及10台SPLASH10-F Fastloc®，均由Wildlife Computers公司出品。为校正原始Argos位置估算结果中的定位误差并统一点位的时间间隔，研究团队采用bsam R软件包结合基于JAGS的马尔可夫链蒙特卡洛（Markov Chain Monte Carlo, MCMC）采样方法，应用了5小时与6小时时间步长的分层贝叶斯状态空间模型（hDCRW）（Jonsen等，2013）。
