Thanks to Marta for bringing this awesome shark expedition site to my attention. Ocearch is a serious tagging operation that catches Great Whites, hauls them onto a submersible sling, and then measures, tags, and samples these magnificent beasts before releasing them back to the sea.
They are currently having great success off of Cape Cod and have tagged two big sharks in the past week or so.

Once tagged, the sharks can be tracked online.
