摘要: |
在1984—1985年胶州湾海洋初级生产力调查期间,作者观测了两个测站海水透明度和水下照度。结果表明,入射可见光中,平均有37.8%被海表面反射掉;垂直消化系数(λ0-9)与透明度的关系为: λ0-9=1.19╱Ds。真光层的下限深度:D1%=3.49Ds,即D1%=4.13╱λ。赛克圆盘可见下限深度处的照度平均是海表面照度的20.39% |

AN ANALYSISOF ANNUAL OBSERVATION DATAON TRANSPARENCY AND SUBMARINE ILLUMINANCE AT TWO STATIONS INJIAOZHOU BAY |

Abstract: |
We observed the Secchi disc depth and submarine illuminance during the investigation of primary productivity in jiaozhou Bay in 1984-1985. The results indicate that the reflection loss by sea surface of the sun light is 37.8% on an average and the vertical extinction coefficient λ0-9=1.19╱Ds where D2 represents the depth of Secchi disc; and the lower limitdepth of euphotic zone D1%=3.49Ds, that is to sat, D1%=4.13╱λ. The illuminance at theSecchi disc depth is 20.39% of that on sea surface on the average. This value approaches to that observed in Bohai Sea (Fei Zunle, 1984). |
