Robots to replace Navy's mine-hunting dolphins

Robots to replace Navy's mine-hunting dolphins
Sunday 02 December 2012

Some dolphins used by the US Navy to track down mines will soon lose their jobs to robots but they will be reassigned, not retired.

Starting in 2017, 24 of the Navy's 80 military-trained dolphins will be replaced by a 12ft unmanned torpedo-shaped vehicle, according to the newspaper U-T San Diego.

The military said the machines can do some of the same mine-hunting duties as the dolphins. And they can be manufactured quickly, in contrast to the seven years it takes to train a dolphin.

But the dolphins will not be relieved of all duties. They will be used along with sea lions for port security and retrieving objects from the sea floor, the newspaper reported.

2. The devices probably look quite a bit like this "spy torpedo" captured by...

...the North Koreans (I use the term "captured" very loosely, BTW) in 2004:

a drone/robot that was swimming like a fish...modeled after a tuna.

It was awesome and kinda creepy at the same time.

tesla had plans to make submersable drones. and i find it very annoying that the dolphins were used for mine detction and removal. reminds me of the day of the dolphin movie. am glad that the navy is moving a way from using the dolphins.

9. Could it be that the Navy finally accepted the Persian Gulf is NOT good Dolphin waters??

During the Start of the Gulf War, I remember reading that the US Navy Dolphins were having problems adjusting to the Persian Gulf. The reason is the Persian Gulf is less salty then the rest of the ocean, given it narrow shape, tight exit to the ocean and massive flow of fresh water from the Euphrates and Tigris Rivers in Iraq and the various rivers flowing into it from Iran.

The Dolphins had a hard time adjusting to the lack of Salt. Dolphins are sea creatures built around "normal" salt levels. In areas where salt is less due to river input, they can swim for a while, then have to move out. Salt water animals keep pumping salt OUT of they body, due to the massive influx from the sea they are swimming in. Fresh water fish and other animals have a body system the keeps salt INSIDE their body, since they is little if any salt in the water they swim in. Some fish do operate in both types of water, but only for short periods of time (Salmon up the rivers to spawn and then down rivers to the sea is the most commonly known type of both fresh and salt water fish). The Fresh water Dolphins of the Yangtze (now believed extinct) and the Amazon are believed to be descendant from ocean going dolphins, but have lost they ability to operate in salt water, for they operate in fresh water.

Please note, the article I read did NOT say the Dolphins were NOT doing what they were trained to do, but that they were getting sick due to the reduce level of salt in the waters of the Gulf and what the Dolphins needed were frequent removal to areas further out in the ocean to recover.

I suspect the problems with Dolphins adjusting to the level of Salt in the Water is the reason for the shift, the other sea of concern right now is the Black Sea, and it is even worse, it is a salt water top over a fresh water bottom. Now the Black sea has dolphins, but I can NOT find a site that say they interbreed out side of the Black Sea, i.e. while the same type of dolphins as elsewhere, how much have they adopted to the special conditions of the Black Sea, On the other hand all are small enough to travel the Bosporus and the Straits of the Dardanelles to mix with other dolphins, so may NOT be a problem for the Dolphins of the Black Sea for the same reason it is not a problem for native Dolphins of the Persian Gulf (i.e. the Dolphins when they start to get sick due to the lack of salt, just go out to the deep ocean and leave they bodies adjust).

My point is the time off task needed for the Dolphins may be the real reason for the change, the Robot does NOT have to be pulled back to deep ocean after a couple of weeks in the Persian Gulf.

10. I for one am very pleased that the Navy

will not be using dolphins for this crappy job. Robots with all their developmental problems are much better for the job.
