提出该海域叶绿素—a含量的分布:调查区西部最高,>0.8mg/m~3,出现了两个高值区:中部是0.4～0.8mg/m~3;东部和最南部最低,<0.4mg/m~3。此分布同水团密切相关。调查区内叶绿素—a变化范围是0.2～18.7mg/m~3。在垂直分布上,叶绿素—a同跃层密切相关,呈现出三种分布类型。在不同的断面或同一断面上,由于环境条件的不同,叶绿素—a含量在断面上显示出不同的分布格局。叶绿素—a含量分布还与黑潮次表层水涌升有关。
The content of chlorophyll-a in the sea area is the highest in the study area, which is the highest in the survey area> 0.8mg / m ~ 3. There are two high value areas: the middle is 0.4 ~ 0.8mg / m ~ mg / m ~ 3. This distribution is closely related to the water mass. The range of chlorophyll-a in the survey area is 0.2 ~ 18.7mg / m ~ 3. In the vertical distribution, chlorophyll-a synchronicity is closely related, showing three distribution types. In different sections or the same section, due to the different environmental conditions, chlorophyll-a content in the cross section showed a different distribution pattern. Chlorophyll-a content distribution is also related to Kuroshio sub-surface water surge.
