  • Aside from rich fishing resources, the Atlantic Ocean also has an abundant number of natural petroleum deposits and gas fields.
  • There are four trenches in the Atlantic that go way beyond the ocean’s depth average of 10,000 feet. These are the Puerto Rico trench, the Laurentian Abyss, the Romanche Trench, and the South Sandwich Trench.

  • The Atlantic Ocean played a huge role in the history of intercontinental communications. The first telegraph cables were laid here in 1866, thereby linking Europe and North America together. Telegraph was the fastest form of communication during that period.
