Publikováno v: Quaternary Research. 88:430-445

The Sea of Japan (also termed the East Sea) has a circulation system isolated from the Pacific Ocean and East China Sea. The East Asian winter monsoon drives the circulation system and cools the Tsushima Warm Current (TWC) to form the Japan Sea Inter

Radiolarian Assemblages in Surface Sediments of the Japan Sea

Autor: Mayumi Hoshiba, Yasumi Yamada, Isao Motoyama, Takuya Itaki

Publikováno v: Paleontological Research. 20:176-206

Radiolarian assemblages in 69 surface sediment samples from the Japan Sea were moderately diversified, consisting of about 100 taxa in total, although only a few species accounted for a large proportion of most assemblages. First, the assemblages wer

Variation in the eastern North Pacific subtropical gyre (California Current system) during the Middle to Late Miocene as inferred from radiolarian assemblages

Autor: Shin-ichi Kamikuri, Isao Motoyama

Publikováno v: Marine Micropaleontology. 155:101817

The California Current has influenced the primary productivity along the California margin, which plays a significant role in global carbon cycles. Although previous studies have explored the response of the California Current to climate change since

This study, based on 3.5 kHz SBP, 3D seismic data and long piston cores obtained during MD179 cruise, elucidated the timing and causes of pockmark and submarine canyon formation on the Joetsu Knoll in the eastern margin of the Sea of Japan. Gas hydra
