At a considerable distance, I'd guess. Wonder if they shoot it with an underwater version of a tranquilizer gun, like the ones used on bears?

Good question, Chuck. I'm also wondering what portion of the great white population is tagged. If it's a small portion, a reading that says there are no sharks in the area won't indicate any real safety.

I'm curious how anyone places a tracking tag on a great white.

Nice article, Elizabeth. Since this tracker tracks tagged sharks, is there a good number of sharks that are tagged. Is there in ongoing effort to tag more sharks?

Thanks for the reference links, Ann.  I look forward to watching them.

Obviously this device has proven itself to be extremely durable and robust.  I didn't realize that it had such pedigree.

Clinton, the Wave Glider is an amazing machine. We included it in our Nautical Robots slideshow:
http://www.designnews.com/author.asp?section_id=1386&doc_id=246206&image_number=3
It's won world distance records for unmanned devices, traveling more than 3,200 nautical miles across the Pacific Ocean. I think it recently broke that distance record. You can check out its specs here:

Elizabeth,

Nice article. 

The amount of punishment this device will experience out on the open sea will be tremendous.  Did they mention any of the provisions or features they included to help it survive?  For example, how does the craft right itself after being flipped by waves?

I'm with you @Jennifer! 
 
I was totally tongue-in-cheek with a dash of devil's advocate. As a sensors guy, I love this story. I'm especially jazzed about the "Bue Serengeti Initiative". It is difficult to make effective policy and manage resources effectively if all you have to base it on is intuition and gut feeling --- hard data is always the answer.  =]

@williamlweaver - based on the world we live in today, you are probably not too far off when you say the great whites will be filing a suit regarding privacy. I'm sure there is an activist group out there who thinks this is just plain wrong/inhumane.

I, however, applaud this effort and hope to see it expanded. We sure could use it up here in Massachusetts.

Why should the location of 7 Billion Humans be the only thing that is tracked? Let's start tracking all of the planet's organisms. That is of course until the Great Whites file a class action law suit for privacy violations. ...why else would Lawyers be called "sharks"?
