Pretty cool image, looks like a lake inside a lake. (Check out the diver to the left)

Apparently it´s fresh water 29 meters down, then 1m hydrogen sulphide (top layer that looks like a lake)
and then below that it´s 30-60 METERS of saltwater.
Looks like it´s only about knee-high water there, not 30 plus

Inside of a grenade. Never seen that before.

Anyone know how the mechanism works? What is the turquoise stuff for example?

Inside of a grenade. Never seen that before.

Well, this seems to be an M62a2 fragmentation grenade. It's described as an "impact" grenade and meant to go off when it strikes something hard. If it doesn't "impact" it will go off in four seconds[or so].

So what happens? This is a tough one. The ubiquitous "pin"[seen behind the safety lever] holds down the safety lever. The grenade is held securing the lever which flies off when the grenade is lofted. Once the lever is gone, a spring[the white circle around the hinge pin] rotates the striker[white thing under the lever] and is flipped into contacting the primer for the thermal charge. The primer is above the turquoise thermal charge. The thermal charge has two tasks, first it must set the impact switch so it can go off and if there is no impact it must continue to to force the situation where a detonation will happen.

Firstly the thermal charge expands its container, this puts a pressure on the log rod going down the center which already has a preloaded spring pushing on it. the slanted lower end of this rod provides an action similar to that of common "automatic" center punch used for locating a place to drill a hole. There is a locking device, a safety, that's located under the spring and around the rod that prevents it from just doing it's thing until the spring is compressed by the action of the thermal charge.

On impact, the long rod "jostles"[like that?] the firing pin in the detonator[the short rod above the red stuff]. The red stuff is a primer that sets off the real charge that fills the inside of the grenade. This explosive force makes the square shaped wire that is coiled around the inside of the shell blow out and away. The coiled wire is serrated and the wire breaks apart at many of these separating it into hundreds of fragments.

If there is no impact, the thermal charge will eventually create a force large enough for the long rod to move the rod in the impact switch enough to cause a detonation.
