Note that the sharks tagged in this article are very small compared to great whites, so tagging them is possible and a lot less dangerous. I think Scott's point is well taken--there's a huge amount that we don't know about the ocean and its ecosystems, and perhaps robotics will help us learn more.

I like the concept. If enough variety of species could be made "trackable", then interspecies interactions as well as environmental responses might give us a wealth of information.  It seems we know more about the inner workings of atoms than we do about ocean ecosystems.

Chuck, I think you just identified the problem with tracking sharks in order to ensure beach safety. I would guess that even a strong effort to tag sharks would leave countless sharks untagged.

If the Great Whites need to be tagged, I'm afraid I won't be able to volunteer for the job, Rob. I'm busy that day.

Hi Rob, Thanks for the comment. It may be possible with today's tech but hopefully someone reading this post can shed some light on the answer.

Good question about whether it could be used to track jellyfish, MrDon. My guess is that it would be difficult to tag a jellyfish -- their tissue seem too fragile. But it may depend on the nature of the tag.

Hi Ann, I didn't think about how researchers would tag jellyfish because of their fleshy bodies when discussing the application. Good Question!!!

mrdon, that's an interesting question about tagging jellyfish. The jellyfish's flesh would have to be solid enough--and they would have to be capturable without harm to them or us--to be tagged in the first place. The researchers in this project designed a special sling to hold sharks while they were tagging them. I'd bet tagging jellyfish is a lot harder. Does anyone know if there's already a tagging system for these slippery critters?

Hi Rob, I agree. I wonder if this robot can track the Box Jellyfish which has been a plague to Australian Beach goers for years? Also, does the torpedoe shape of the robot seem threatening among onlookers, especially the Coast Guard, while it tracks Sand Tiger Sharks? As always, very nice article Ann!

I agree, Elizabeth, there are tons of applications for this type of sea tracking. It would be interesting if there were a widespread effort to tag great whites. That would be the only way to help avoid beach attacks.

Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
