What is a minelayer ship?

Definition of minelayer : a naval vessel for laying underwater mines.

What type of mine is used with the volcano?

The system uses prepackaged mine canisters which contain multiple anti-personnel (AP) and/or anti-tank (AT) mines which are dispersed over a wide area when ejected from the canister.

Are there any ww2 sea mines still active?

Although the known mine danger areas in the Gulf have been swept extensively, lookouts on warships are still trained to spot floating mines, just in case. Live naval mines from World War II are still occasionally found in the North Atlantic and the Baltic Sea, and are also destroyed.

Is laying mines illegal?

Anti-personnel landmines are prohibited under the Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on Their Destruction (or Mine Ban Convention), adopted in 1997. More than 150 countries have joined this treaty.

Is laying mines a war crime?

Placing minefields without marking and recording them for later removal is considered a war crime under Protocol II of the Convention on Certain Conventional Weapons, which is itself an annex to the Geneva Conventions.

What are mine layers called?

“Minelayer” lasted well past the last common use of “mine planter” in the late 1940s. An army’s special-purpose combat engineering vehicles used to lay landmines are sometimes called “minelayers”.

What is naval minesweeper?

U.S. Navy minesweepers are relatively small naval warships designed to counter the threat of sea mines. They have two primary purposes in naval warfare. One is to clear waterways of mines to protect the nation’s warships and merchant shipping.

Do volcanoes shoot diamonds?

The answer lies in rare and unusual volcanoes called kimberlites. These deeply-seated volcanic eruptions can sometimes pick up diamonds, along with other minerals and rock fragments, and blast them to the top. Think of kimberlites as elevators that diamonds use to ride up to Earth’s surface!

Does lava create diamonds?

From Russia, With Carbon. A recent paper by Galimov and others in American Mineralogist details the tiny diamonds they found in lavas from Tolbachik. These crystals are less an a 0.03 inches and mostly found in the rocks made during the lava fountain phase of the eruption.

A WWII-era sea mine could definitely explode. Mines used in more recent wars are often set to deactivate, with clocks that can either interrupt the firing circuit or detonate the mine, but older models have no such “off” switch.

Does the Navy still use minesweepers?

Today, the only active minesweeper class is the Avenger class, which is a part of the MCM ship designation. In January 2022, the U.S. Navy was operating eight active Avenger-class minesweepers. These ships were built with significantly lower acoustic and magnetic signatures to avoid detonating sea mines.

Does lava contain gold?

The fact that active volcanoes produce gold is not that surprising, Dr. Noble said. Significant quantities of gold are also being found along mid-ocean ridges, where so-called “black smokers” emit magma from beneath the ocean floor. Such spots are loaded with minerals, he said.
