일본 원자력환경정비기구는 도쿄에서 약 2,000km 떨어진 미나미토리시마를 원자력 폐기물 처분장으로 적합한지 판단하기 위해 지질학적 문헌 조사를 실시할 예정이다.
미나미토리시마는 오가사와라 제도에 위치해 있다. 이 외딴섬이 원자력 폐기물을 수용할 수 있는지 판단하기 위한 문헌 기반의 지질 조사가 시작될 예정이다.
이번 조사는 일본의 방사성 폐기물 관리 노력의 초기 단계에 해당한다.
향후 일정이나 다음 단계에 대한 구체적인 내용은 아직 발표되지 않았다.
Japan has identified an enormous underwater rare earth deposit 6,000 meters deep near Minamitorishima, the remote Pacific atoll central to its accelerated deep-sea mining plans. Detailed in a recent WIRED report, the find—building on equipment installation earlier this year—bolsters Tokyo's drive for independence from Chinese supplies of these critical manufacturing materials.

Japan plans to start a Minamata disease survey on residents along the Shiranui Sea coast in Kumamoto and Kagoshima prefectures as early as this year. The survey marks the first under a special law that took effect in 2009.
China's Ministry of Natural Resources has published an atlas from two decades of marine geological surveys, mapping the location, concentration, and distribution of dozens of elements in seabed sediments, including rare earths, iron, manganese, and copper. State broadcaster CCTV reported the atlas as a 'master navigation map' for marine development and conservation, based on over 20,000 observation points. Researcher Dou Yanguang from the Qingdao Institute of Marine Geology said it enables precise targeting of resources and identification of sensitive ecological zones.
