| 内容記述 | Dissolved organic carbon (DOC) and particulate organic carbon (POC) in sea water of the western North Pacific Ocean and Seto Inland Sea which were determined during 1969-1975 are summarized synthetically. In the western North Pacific, DOC was determined at 4 stations. Considerable differences of DOC among water areas were not observed and the mean value of surface waters up to 100m deep of these 4 stations was 1.10±0.22 mgC/1 (mean±s.d.). In Hiuchi Nada, central part of Seto Inland Sea, the mean values of DOC and POC through four surveys carried out in 1969, 1970, and 1975 were 1.45±0.22mgC/1 and 0.270±0.118 mgC/1, respectively. For the calcuration, the values obtained in sea water polluted with pulp wastes and red tides were omitted. DOC in the inner part of Osaka Bay was more than 2mgC/1, but in central water area, DOC and POC were maintained to nearly the same levels to that of Hiuchi Nada. DOC is usually mainetained in the range of 1.0 to 2.0 mgC/1 in both coastal and open sea water except the polluted or heavily eutrophicated water areas. The regulation of DOC concentration in sea water is achieved by bacterial mineralization activity which is elevated exponentially with the increase of DOC and POC. But POC concentration which is affected by productivities of phytoplankton fluctuates seasonally and locally. The rations of DOC to POC are lower in coastal water than in open sea water, ranging 4-9 in the former and 10-30 in the later, respectively. | |||||||||||||||||

| 内容記述 | 西部北太平洋および瀬戸内海の有機物濃度を1969年から75年にかけて溶存有機炭素(DOC), けん濁有機炭素(POC)として測定した. その結果, 一部の過栄養海域, 赤潮域を除けば, 外洋表層水, 内湾水ともにDOC濃度は1?2mgC/1の範囲にあることが明らかとなった. これは有機物の供給量の増大にともなって微生物の無機化活性が指数関数的に増大することに起因するものと考えられる. 一方POC濃度は海域, 季節間の変動がDOCに較べて大きい. 富栄養化水域ではPOC濃度が高く, DOC/POCが小さくなる傾向が認められた. | |||||||||||||||||
