Submarine Mass Movements and Their Consequences
Yasuhiro Yamada,Kiichiro Kawamura,Ken Ikehara,Yujiro Ogawa,Roger Urgeles,David C. Mosher,Jason D. Chaytor,Michael Strasser,Michael Strasser +8 more
TL;DR: Weimer et al. as discussed by the authors showed that 30% of the World's population lives within 60 km of the coast, and the hazard posed by submarine landslides is expected to grow as global sea level rises.
Journal ArticleDOI
Transgressive and highstand systems tracts and post-glacial transgression, the East China Sea
Yoshiki Saito,Hajime Katayama,Ken Ikehara,Yoshihisa Kato,Eiji Matsumoto,Kazumasa Oguri,Motoyoshi Oda,Mariko Yumoto +7 more
TL;DR: In this paper, the Late Pleistocene-Holocene depositional sequence on the shelf in the East China Sea (ECS) is interpreted on the basis of the analyses of four sediment cores and high-resolution seismic reflection sub-bottom profiler records along a NE-SW across-shelf transect.
Journal ArticleDOI
Abrupt ventilation changes in the Japan Sea over the last 30 ky: Evidence from deep-dwelling radiolarians
TL;DR: In this article, the modern depth distribution of radiolarian species and their relation to water masses was elucidated from the study of plankton tows and surface sediments, and seven sediment cores located in water depths ranging from 807 to 3613 m, indicating changes in waterventilation strength in this marginal sea.
Journal ArticleDOI
Rock-magnetic changes with reduction diagenesis in Japan Sea sediments and preservation of geomagnetic secular variation in inclination during the last 30,000 years
TL;DR: A rock-magnetic and paleomagnetic study was conducted on a sediment core of about 4.4 m long taken from the northeastern part of the Japan Sea, which was dated by nineteen radiocarbon (14C) ages.
Journal ArticleDOI
Orbital-scale stratigraphy and high-resolution analysis of biogenic components and deep-water oxygenation conditions in the Japan Sea during the last 640 kyr
TL;DR: In this article, the authors constructed an orbital-scale stratigraphy of the sediments covering the last 640kyr by comparing the SPECMAP ∂18O curve and the ∂ 18O curve of planktonic foraminifera (∂18Opf) in the Japan Sea together with the combination zones of dominant planktonics foraminifa species.
