How's the deepsea diver?

The diver made another discovery.

So Diver A plays the scarf whistle or Diver B plays the sargassum whistle to request a toy from whoever has it.

The pilot made this great observation That's hot.

Well, the diver who went down to inspect the bottom of the ship... came across the hull of another boat a little sailboat.

So Diver A and Diver B both have a wearable computer and the dolphin hears the whistle as a whistle, the diver hears the whistle as a whistle in the water, but also as a word through bone conduction.

And of course there're multiple displays, to get the information to the diver.

And there are multiple displays, to get the information to the diver.

You can see the skydiver with the red suit, he's in a stand up position.

The diver here has a rope toy, and I'm on the keyboard on the left, and I've just played the rope key, and that's the request for the toy from the human.

When the diver carries many diving cylinders, especially those made of steel, lack of buoyancy becomes a problem.

Now, instead of pushing a keyboard through the water, the diver's wearing the complete system, and it's acoustic only, so basically the diver activates the sounds on a keypad on the forearm, the sounds go out through an underwater speaker, if a dolphin mimics the whistle or a human plays the whistle, the sounds come in and are localized by two hydrophones.

What we hope will happen is that the dolphin mimics the whistle, and if Diver A has the sargassum, if that's the sound that was played and requested, then the diver will give the sargassum to the requesting dolphin and they'll swim away happily into the sunset playing sargassum for forever.

The BCD is used to compensate for the compression of a wet suit, and to compensate for the decrease of the diver's mass as the air from the cylinder is breathed away.

It is said that loons have been caught in the New York lakes eighty feet beneath the surface, with hooks set for trout though Walden is deeper than that.

At length having come up fifty rods off, he uttered one of those prolonged howls, as if calling on the god of loons to aid him, and immediately there came a wind from the east and rippled the surface, and filled the whole air with misty rain, and I was impressed as if it were the prayer of the

Wingsuit jumping is the leading edge of extreme sports an exhilarating feat of almost unbelievable daring, where skydivers soar through canyons at over 100MPH. Ueli Gegenschatz talks about how he does it, and shows jawdropping film.

So, a diver with a 3 litre oxygen cylinder filled to 200 bar who leaves 25 in reserve will be able to do a 450 minute 7.5 hour dive (3 L 200 bar 0.75 1).

Using the same type of equipment as scuba diving, the diver breathes from compressed air cylinders, which float on a free floating raft at the surface, allowing the diver only 20 30 feet (6 9 m) of depth to travel.

Open circuit The gas endurance of open circuit demand scuba depends on factors such as the capacity (volume of gas) in the diving cylinder, the depth of the dive and the breathing rate of the diver, which is dependent on exertion, fitness, physical size of the diver, and experience among other factors.

In technical diving, the diver may carry different equipment for different phases of the dive some breathing gas mixes may only be used at depth, such as trimix and others, such as pure oxygen, which only may be used during decompression stops in shallow water.
