en: The carbon captured by living organisms in oceans is stored in the form of sediments from mangroves, salt marshes and seagrasses. We evaluated the blue carbon sinks by gastropod Cerithidea cingulata in river mouth tidal flat. We determined oxygen consumption of C. cingulata in the air and water conditions. Oxygen consumption grew with increasing temperature and shell length in both conditions. Approximately 80% of the carbon biomass was an inorganic carbon from shell origin. We calculated that the amount of carbon source as respiration and dead was 26 kgC/year, sink as production, shell formed, shell buried was 40 kgC/year in this muddy tidal flat. These results indicated that C. cingulata plays a role for contribution to sink the blue carbon

en: The Amagasaki Canal is an enclosed waters located in innermost recesses of Osaka Bay. In this areas, we confirmed that the canal have been polluted and increased the sedimentation of organic matter because the canal is sheltered waters with artificial vertical structures and is affected by waste water from factories. According to the consumption of oxygen by the organic mud, there is anoxic water in the bottom of the canal. In this study, a field experiment for clarify the adjustability of the new aeration technique was executed. A basic performance of the diffused aeration based on microscopic bubble was evaluated. Consequently, the control methods for the system and affectivity for attached organism were clarified.

en: Many coastal structures, especially embankment and revetment, were damaged seriously by Tsunami of Tohoku Earthquake occurred at March 11, 2011. However, many Gentle Slope-type Revetments were not broken and remain the function of disaster prevention. In this study, we focused generation mechanism of robustness of Gentle Slope-type Revetments to overflowing tsunami on the basis of field observation in Miyagi Prefecture and numerical analysis.The field observation revealed that almost no Gentle Slope-type Revetments were broken. Numerical results suggest that the robustness of the Gentle Slope Revetments is due to the decrease in the water surface elevation of the overflow and the landside scour depth.

en: Styela plicata inhabits the area along the shore, it is filter feeder and attaches to the surface of coastal structure wall. This study aims to clarify influence of water temperature and salinity on suspended solids feeding activity of S. plicata. When water temperature decreased from 20℃ to 10℃, the amount of filtered water and food consumption of S. plicata decreased to about half. On the other hand, both made a little difference when water temperature increased from 20℃ to 25℃. In addition, the amount of filtered water and food consumption of S. plicata increased in proportion to wet weight, but when salinity decreased from 30 psu to 20 psu, both decreased, and there were not the relations with the wet weight, and it was with a constant value.

en: The Amagasaki Canal where is an enclosed waters have been polluted and occurred eutrophication and hypoxic condition chronically. According to restore water environment in the canal, design of new restoration plant and substantiative experiment are preceded by the Amagasaki Sea Blue Project. In this study, long-term field experiment of water quality improvement technique using algae was examined. Water of sea bottom drawn from the canal and flow into the experimental small channel. This study focused on reduction of nutrients concentration and aeration with the photosynthesis by algas which was luxurianced naturally. As a result, it is found that the technique was very effective in daytime and summer in particular and disposal of exuberant algae will be required for isolation from material circulation in the canal.
