About Angel

The Story Behind the Name: Angel Li is the glue that holds this virtual experience together. He is the mastermind behind the complicated satellite tracks seen here. Not only does he keep the entire Rosenstiel School of Marine and Atmospheric Sciences website going, but he also builds and manages the SRC website too. We would like to thank him for his ongoing efforts to connect our work with the general public. Angel is as invaluable of an asset to our team as this shark is to our ocean.

Satellite Tagging: Angel was carefully tagged with the latest in satellite tag technology providing us with the first opportunity to follow the long term movements of these threatened species. Please keep checking back frequently to follow Angel’s movements, which will be updated every few days as his satellite tag continues to send us real-time tracking data.
