| Research Abstract |
Sediment traps were moored in Japan Sea and Western North Pacific. Settling particulate matter (Marine Snow) were collected and analyzed chemical components. At both areas, particulate matter fluxes were large in spring season, while small in winter season. Biogenic opal was dominant in large particulate flux periods, and aluminosilicate materials were dominant in small particulate flux periods. Change of chemical elements during 15 years was suggested change in transport processes of land -origin particulate materials in the Japan Sea deep water.
