The average bottom water temperature (BWT) from 2010 to 2014 differed among the sea regions, for example, in January,it was lowest at Harima Nada and Bisan Seto (7.3-10.0℃) and highest in Kii Suido and Bungo Suido (11.5-14.4℃).BWT ranged from 15.0 to 23.3℃ in May and July, and from 22.5 to 25.2℃ in October. The spatial distribution of cold- or warm-water bodies corresponded well to those of high-salinity waters, indicating penetration of the Kuroshio Current from the Pacific Ocean. BWT increased significantly from the 1980s to 2010s in most sea regions and seasons.The overall mean increase in BWT was the largest in October (+5.82℃ 100-yr^<-1>), especially in Osaka Bay and Hibiki Nada (+9.25 and +9.10℃ 100-yr^<-1>, rspectively). Hypoxic bottom water (dissolved oxygen [DO] < 4.0 mg l^<-1>) occurred mainly in inner Osaka Bay in May, July, and October. From the 1980s to 2010s, the bottom DO gradually increased in five sea regions in July, but decreased in Kii Suido and Osaka Bay in October, which may partly be due to the rising BWT in autumn. The chlorophyll a concentration d creased significantly from the 1980s to 2010s in two to eight regions in January, May, July, and October. By contrast, chlorophyll a increased significantly in Harima Nada (January, July, and October), Bisan Seto (January and May), and Bingo Nada (January).","subitem_description_type":"Abstract"}]},"item_10008_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本報文は、過去の行政調査データを用いた1981～2015
