Shark Tracker
Also, I barely swim in the Atlantic ocean, the Ocearch Shark/Turtle/Wahle/Dolphine and some other species Tracker shows you recent movements of individuals out of the above-mentioned species.
The probably coolest feature is the fact, the tracked animals are known by name and the fact…
…you can drill down into the travel activity (let’s ignore the GDPR for a moment) of each animal as well, keep a favourite list and so on.
Unfortunately, it looks like the data is not publicly available. I just think about some ideas of how to process the data and predict movements and so on using some nice algorithms. If you want to access the data, you need explicit permission to do so.
