Blair Thornton,Tomoko Takahashi,Takumi Sato,Tetsuo Sakka,Ayaka Tamura,Ayumu Matsumoto,Tatsuo Nozaki,Toshihiko Ohki,Koichi Ohki +8 more
TL;DR: In this article, a deep-sea laser-induced breakdown spectrometer (ChemiCam) was deployed to perform in situ multi-element analysis of both seawater and mineral deposits at depths of over 1000m.
Journal ArticleDOI

Yutaro Takaya,Kazutaka Yasukawa,Kazutaka Yasukawa,Takehiro Kawasaki,Koichiro Fujinaga,Koichiro Fujinaga,Junichiro Ohta,Junichiro Ohta,Junichiro Ohta,Yoichi Usui,Kentaro Nakamura,Jun-Ichi Kimura,Qing Chang,Morihisa Hamada,Gjergj Dodbiba,Tatsuo Nozaki,Koichi Iijima,Morisawa Tomohiro,Kuwahara Takuma,Ishida Yasuyuki,Takao Ichimura,Masaki Kitazume,Toyohisa Fujita,Yasuhiro Kato,Yasuhiro Kato,Yasuhiro Kato +25 more
TL;DR: The enormous resource amount and the effectiveness of the mineral processing are strong indicators that this new REY resource could be exploited in the near future.
Journal ArticleDOI
Uranium isotope systematics of ferromanganese crusts in the Pacific Ocean: Implications for the marine 238U/235U isotope system
Kosuke T. Goto,Ariel D. Anbar,Gwyneth W. Gordon,Stephen J. Romaniello,Gen Shimoda,Yutaro Takaya,Ayaka Tokumaru,Tatsuo Nozaki,Katsuhiko Suzuki,Shiki Machida,Takeshi Hanyu,Akira Usui +11 more
TL;DR: In this article, the authors investigated the spatial variation of δ238U in modern ferromanganese (Fe-Mn) crusts by analyzing U isotopes in the surface (0-3mm) layer of 19 Fe -Mn crusts collected from 6 seamounts.
Journal ArticleDOI
Discovery of extremely REY-rich mud in the western North Pacific Ocean
Koichi Iijima,Kazutaka Yasukawa,Kazutaka Yasukawa,Koichiro Fujinaga,Koichiro Fujinaga,Kentaro Nakamura,Shiki Machida,Yutaro Takaya,Junichiro Ohta,Satoru Haraguchi,Yoshiro Nishio,Yoichi Usui,Tatsuo Nozaki,Tatsuo Nozaki,Tatsuo Nozaki,Toshitsugu Yamazaki,Toshitsugu Yamazaki,Yuji Ichiyama,Akira Ijiri,Fumio Inagaki,Hideaki Machiyama,Katsuhiko Suzuki,Yasuhiro Kato,Yasuhiro Kato,Yasuhiro Kato +24 more
TL;DR: In this article, the geochemical society of Japan has proposed that rare-earth elements and yttrium are essential elements for products with advanced and green technologies, because of the magnetic and optical properties of REY that result from the characteristic configurations of electrons in these elements.
Journal ArticleDOI
Post-drilling changes in fluid discharge pattern, mineral deposition, and fluid chemistry in the Iheya North hydrothermal field, Okinawa Trough
Shinsuke Kawagucci,Junichi Miyazaki,Ryota Nakajima,Tatsuo Nozaki,Tatsuo Nozaki,Yutaro Takaya,Yasuhiro Kato,Yasuhiro Kato,Takazo Shibuya,Uta Konno,Yuzuru Nakaguchi,Kenta Hatada,Hisako Hirayama,Katsunori Fujikura,Yasuo Furushima,Hiroyuki Yamamoto,Tomo-o Watsuji,Jun-ichiro Ishibashi,Jun-ichiro Ishibashi,Ken Takai +19 more
TL;DR: The Integrated Ocean Drilling Program (IODP) Expedition 331 investigated the Iheya North hydrothermal field in the Okinawa Trough Several post-drilling underwater vehicle investigations were conducted over 2 years to identify postdrilling changes in fluid discharge pattern, mineral deposition, and fluid chemistry as mentioned in this paper.
