The Challenger Deep in the Marianas Trench is the deepest point in the world that we're aware of so far, plunging nearly 11 kilometers beneath the waves.
The names of these islands became well-known: Tarawa in the Gilbert Islands. Truk in the Marshall Islands. Saipan in the Marianas, and other islands including Guam and Tinian.
From April 20th to July 10th, NOAA, the National Oceanic and Atmospheric Administration, is on a mission to explorethe Marianas Trench in the western North Pacific Ocean.
That having been said, in terms of concrete results, the early air war here from the Marianas, the bombing of Japan, somewhat underwhelming in terms of results.
When darkness fell, the Flying Fish, the submarine, surfaced and sent out her message, quote, the Japanese fleet is heading for the Marianas, end quote.
