The Mariana Trench in the Pacific ocean descends to a staggering depth of almost 11km.
The Center for Coastal and Ocean Mapping used a multibeam echosounder on a hydrographic ship to take the measurements which are some of the most precise ever made and indicate a depth so deep that the bottom extends further down below sea level than Mount Everest extends above it. "We mapped the entire trench, from its northern end at Dutton Ridge, all the way to where it becomes the Yap Trench in the south," said Dr. Jim Gardner.
"US scientists have mapped the deepest part of the world's oceans in greater detail than ever before."
