The Ocean Depths
The greatest depths known of the sea is in the South Atlantic Ocean, midway between the island of Tristan d’Acunha and the mouth of the Rio de la Plata. The bottom was there reached at a depth of 40,236 feet, or eight and three-quarter miles, exceeding by more than 17,000 feet the height of Mount Everest, the loftiest mountain in the world. In the North Atlantic Ocean, south of Newfoundland, soundings have been made to a depth of 4580 fathoms, or 27,480 feet, while depths equalling 34,000 feet, or six and a half miles, are reported south of the Bermuda Islands. The average depth of the Pacific Ocean between Japan and California is a little over 2000 fathoms; between Chili and the Sandwich Islands, 2500 fathoms; and between Chili and New Zealand, 1500 fathoms. The average depth of all the oceans is from 2000 to 2500 fathoms.
