2004-07和2004-09-10,在菲律宾海西部海区进行了水体现场多参数综合垂向测量和海水取样分析,对菲律宾海水体光衰减作用、悬浮颗粒及颗粒有机碳的相关关系和空间分布变化特征进行了分析讨论。结果表明菲律宾海光衰减系数C与悬浮颗粒浓度、颗粒有机碳与颗粒光衰减系数c,呈显著的线性相关关系,上层水体颗粒有机碳和叶绿素a的比值约为200~3500,浮游植物现存量与颗粒有机碳现存量变化趋势一致。
Multi-parameters of sea water were in-situ measured vertically and water samples were collected in the Western Philippine Sea in 2004. Based on these data and samples, the spatial distributions of and the correlations among seawater light attenuation, suspended particle and particulate organic carbon (POC) are discussed. It is shown that in the study area both between the light attenuation coefficient c and the total suspended matter (TSM) and between the POC and the particle light attenuation coefficient cp show remarkable linear correlations. The ratios of POC to chlorophyll a in the upper waters of the Philippine Sea range from 200 to 3 500 and the changing tendency of the standing crop of phytoplankton is consistent with that of POC.
