Scientists aim to reach the Earth's mantle with an undersea drill Endgadget Mariella Moon
We'd know a lot more about what's under the Earth's crust if Jules Verne's Icelandic volcano weren't but a figment of his imagination. Japan's Agency for Marine-Earth Science and Technology's (JAMSTEC) largest drilling ship called "Chikyu" is very real, though, and a group of international researchers plan to use it to drill into the Earth's mantle for the first time.
The JAMSTEC-led team will conduct a two-week preliminary study in the waters off Hawaii this September to determine if that's where their Chikyu should drill. If the location doesn't work, they'll look at their other choices in the waters off Costa Rica and off Mexico. All three are in the ocean, because the continental crust is twice as thick as the oceanic crust.
