Return of the phantom stranger

It's always fascinating and exciting to see footage of marine life that you would never get to see in real life. In this instance the MBARI have some of the best recorded footage of the ghost shark known as a pointy-nosed blue chimaera.

Sonic Attack

Could this be the start of underwater transmissions, texts, sound and music? Maybe radio location for missing divers? Or do you think that the the underwater world has no place for man made signalling? What effect, if any, would it have on marine life?

"It's easy to take modern wireless communication for granted above ground, but it's useless in areas where the signals can't propagate, like underwater or in caves. DARPA might have a better way: its AMEBA (A Mechanically Based Antenna) team is developing portable ultra-low-frequency (1Hz to 3kHz) and very low frequency (3kHz to 30kHz) transmitters that could penetrate materials like water and stone with basic data. Scuba divers could send text messages to each other, for instance, while search and rescue teams could still contact the outside world while they're in tunnels."

Fisherman's blues

There's a first time for everything. Despite not having been in the water for the last few weeks due to the weather or more exactly the wind, I still managed to end up with a perforated eardrum and an ear infection in the middle of the day while at work. Don't ask me how it happened, I have no idea.

So lots of time spent at the doctors, then even more time at the specialists and all I have to show for it is a ton of drugs and no hearing. Just in time for the holiday season. Hooray. At least I got to see pictures of the aforementioned perforation. It's not a pretty sight looking at the inside of your own ears. Like looking at the moon's surface. Only pinker. And slightly moister. Also having the inner ear reconstructed about 8 years ago makes this a little awkward for the healing process.

Hopefully I'll be good to go in time for the traditional Xmas dive. Or maybe New Year.......

And now for the boring bit if anyone has ever wondered what a perforated eardrum is......
