| Outline of Final Research Achievements |
Atmospheric aerosols, such as desert dust and polluted particulate matter (PM2.5), are transported from continental Asia to surface seawaters of the western Pacific Ocean, and provide a major source of nutrients and trace metals to the marine environments. Supplementing seawater with aerosols possibly change in seawater nutrient composition as well as the marine microbial community. Shipboard experiments in the Pacific Ocean involved the recovery of oligotrophic oceanic water by supplementation with aerosol particulates obtained from the snow-cover mountain. Initial increases in nitrates due to the aerosol addition were followed by a decrease correlated with the phytoplankton (diatoms) increase. The bacterial community also changed with apparent increases in the rates of heterotrophic bacteria in aerosol addition seawater. Our findings provide empirical evidence revealing the aerosol impact on oceanic seawater microbiology by alleviating nitrogen limitation in the organisms.
