The overriding aim is to better protect local or regional turtle populations that may be in danger of extinction. Between 8 marine turtles migrating across the oceans are tracked via the ARGOS satellite system in order to determine their trajectories and identify their geographical distribution the data are then correlated with other sources to analyze their behavior at sea or on land. Marine biologists have a harder time of it. Symbolically important and enigmatic animals, marine turtles fascinate both the scientists investigating them and the general public. Z OOLOGISTS ROUTINELY track animals, from albatross to zebra, using global-positioning-system ( GPS) tags which then return their data via satellite. Modeling of both PTT and GPS-t data resulted in tracks with over 79 of predicted locations less than 5 km from the GPS location (aver-age location error: 3.2 0.1 and 1.7 0.1 km, respectively). In spite of the apparent difficulty of observing these animals, extremely robust and reliable Argos transmitters can record for many months the depth and temperature of the water through which they move and transmit this information to specialists on land who can then either directly track or reconstruct an animal’s trajectory. Some strike us as fearsome, others as fascinating, others again we know little about, and some we fish, often intensively. 2019 Dec 7(1):1-7.There is a vast range of pelagic species below the surface of the seas and oceans. Best practice recommendations for the use of external telemetry devices on pinnipeds. Horning M, Andrews RD, Bishop AM, Boveng PL, Costa DP, Crocker DE, Haulena M, Hindell M, Hindle AG, Holser RR, Hooker SK, Hückstädt LA, Johnson S, Lea MA, McDonald BI, McMahon CR, Robinson PW, Sattler RL, Shuert CR, Steingass SM, Thompson D, Tuomi PA, Williams CL & Womble JN. For 8 different GPS collars models used for animal tracking, Villepique et al. We conclude with four desired future directions for the use of ETDs in technology development, validation studies, experimental designs and data sharing. Over recent years, a major breakthrough in marine animal tracking has occurred with the advent of Fastloc-GPS that provides highly accurate location data even for animals that only surface briefly such as sea turtles, marine mammals and penguins. DiGiovanni serves as Pacific Marine Mammal Centers chief scientist. These recommendations were developed specifically for pinnipeds however, they may also be applicable to studies of other marine taxa. The tracking device, either a splash or spot tag linked to wildlife computers, sends a signal for approximately 80 days to researchers at PMMC and to Robert DiGiovanni of the Atlantic Marine Conservation Society, our collaborating research organization, for analysis.

This equipment makes it possible for Wildlife ACT’s monitors to track these animals daily, which means that if they are injured, sick, trapped in a poacher’s snare, or. These include radio, GPS and satellite collars.

Continued improvement of best practices is critical within the framework of the Three Rs (Reduction, Refinement, Replacement) these best practice recommendations provide current guidance to mitigate known potential negative outcomes for individuals and local populations. To track endangered species like Cheetah, African Wild Dog, Rhino and Leopard, various forms of tracking collars are used. We identify 15 best practice recommendations for the use of ETDs with pinnipeds that address experimental justification, animal capture, tag design, tag attachment, effects assessments, preparation, and reporting.

However, ETDs have limited retention times and their use may result in negative short- and long-term consequences including capture myopathy, impacts to energetics, behavior, and entanglement risk. ETDs are less invasive and easier to apply than implanted internal devices, making them more widely used.

This fundamentally limits access by researchers to critical parts of pinniped life history and has spurred the development and implementation of a variety of externally attached telemetry devices (ETDs) to collect information about movement patterns, physiology and ecology of marine animals when they cannot be directly observed. Pinnipeds spend large portions of their lives at sea, submerged, or hauled-out on land, often on remote off-shore islands.
