Argos satellite tracking makes it possible to follow the paths of tagged animals. This tracking data is invaluable, but sometimes it raises more questions than it answers. Why is the animal making a detour – or even a loop? Does it stay here or there for feeding, or for another reason? If it turns back, could it be due to water temperature?… Over the longer term, comparing tracking data with ocean data can help biologists understand the behavior of the tracked species, and ultimately contribute to their protection.
Below, Argos tracks of one young male elephant seal followed by IMOS, are overlaid on SST (top) and Chlorophyll-A (bottom) maps.

03.08.2020 Animal tracking applications Tracking bottlenose dolphins by night in narrow channels
Dolphins do have a nightlife, but visual observation techniques cannot fully capture this. Also, coastal populations of dolphins sometimes occupy complex, labyrinthine habitats. Here too line-of-sight techniques fall short. Satellite telemetry doesn’t distinguish between night and day, and, as we will see, can track animals through an aquatic…
