Dredging is an excavation activity usually carried out underwater, in shallow seas or freshwater areas with the purpose of gathering up bottom sediments and disposing of them at a different location. This technique is often used to keep waterways navigable. It is also used as a way to replenish sand on some public beaches, where sand has been lost because of coastal erosion. Dredging is also used as a technique for fishing for certain species of edible clams and crabs (see fishing dredge).
See him shining red and gold, rocket boots to make him fly
To defend the innocents dedicates his life
Evil ones all around, till he crush 'em to the ground
An avenger made of steel, he's the Iron Man
[bridge]
He's invincible
Man-machine for war
[chorus]
Under the armor you know there's a man
His greatest weapon his brain
Fightin' with weapons he did by himself
No one can stand in his way
He can be invisible, he has got repulsor rays
Honorable, strong and brave, technologic knight
Without fear he always fights for the justice and the peace
Armored and dangerous, he's the Iron Man
[bridge]
[chorus]
See him shining red and gold, once again he flies around
He's in search of criminals, nowhere they can hide
Hearing his metallic voice, they will sweat and tremble with fear
Knowing they cannot escape from the Iron Man
