In the study area, discharge from the Shin River was one of the sources of nutrients, which were mainly detected in the low salinity surface water around the mouth of the river. Compared with dissolved inorganic nitrogen and silicate, phosphate was remarkably deficient throughout the study area and was likely to be a limiting factor for primary production. Concentration of chlorophyll-a was high in the riverine plume front near the river mouth. Furthermore, by analysis of relation between chlorophyll-a concentration and salinity, primary productivity at the surface was considered to be high in this area. It seems likely that Shin River contributes partly to the supply of organic matter at Igarashi Beach through the primary production enhanced by nutrients in its water.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan
