Interesting link, tyvm OP.
I've been following the tagging program at Ocearch for a few years. Great Whites are one of my primary interests, I've been studying them since I was in single digits, ever since I saw one pulled from the St. Lawrence river network in Ontario, Canada back when I was a kid. It had made its way in from the ocean somehow, and survived at least a day or two in the river.
http://www.ocearch.org/Paul Walker, the actor who recently was killed in that Porsche crash had a degree in marine biology, and was specifically interested in the white sharks as well, and had worked with the Ocearch program, helping tag and document great white behavior. It's pretty interesting data they're putting together on the white sharks. Recently, when a large pod of killer whales was spotted in an area where a lot of tagged white sharks frequent during that time of year, every tag once it resurfaced showed that the white sharks dove deep and rapidly left that area, like 1000ft or more, when the orcas were in the area. Interesting stuff.
Last year's "shark week" had an episode where a group of biologists were trying to tag a white with a beacon, and have a torpedo like "shark cam" follow that beacon, getting autonomous video of a sort. It worked great, and they were able to identify the shark by its markings (usually the rear side of the dorsal fin, it's like fingerprinting for humans in a way) - it was the same one that was in the famous picture/video that stalked the guy in a kayak near Boston's waters. A big fat 17 foot female, probably at least 3000 pounds. When they harpooned/tagged it initially, it was so PO'd that it thrashed itself almost completely clear of the water, quickly reversing course and taking off before settling back down.
Near the top of the bucket list is cage diving in Guadalupe - it's got super clear waters and a ton of large white sharks during the right time of year, and a couple of fantastic ships/boats that do the tour.
