Science & Technology: Expedition to Drill Into Earth's Mantle for First Time

Aiming for the world’s first-ever direct excavation of the Earth’s mantle (see below), an international research group led by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) will conduct a preliminary study in the waters off Hawaii in September, The Yomiuri Shimbun learned Tuesday.

The area is considered to be a leading candidate site for the drilling. The research group, including researchers from Japan, the United States and the Europe, plans to intensively investigate the underground structure of the area to find a suitable spot for drilling.

JAMSTEC and its partners aim to realize the excavation of the mantle in the early 2020s — at the earliest — using Japan’s deep-sea scientific drilling vessel Chikyu.
