Question from A Budding Scientist:
What do tagged animals tell us about the ocean? And when you get this information, what do you do with it? How is it used?
The tracks and the way they move around the ocean tells us where the important regions are. That is places where the animals look for food. The tags on the animals also provide us with information of the temperature of the water over the range the animals dive through. These data are important in understanding climate change and other climate related oceanic processes.
Finally, the data are recovered from the animals and put into the context of movements patterns of other individuals of the same species. This helps us understand what areas of the ocean are important for that species in general, as individual animals have their own tendencies. Lastly, we compare the tracks of all the species we have tagged in an effort to determine what areas of the ocean are important to a larger group of animals.
