High-Tech Monitoring Of a National Marine Sanctuary

摘要

When it took to the seas in 1862, the USS Monitor was a paragon of advanced technology. The Civil War ironclad was nearly impervious to artillery fire with its thick metal shell. Its rotating gun turret allowed the crew to shoot from any direction, negating the need to turn broadside before a battle. Much of its body was underwater, taking away from the enemy's target area. And just the sight of it was fearsome- engine-propelled submarines were not yet patrolling the seas, so sailors had not seen anything like it.
