摘要

摘要: 2004年秋季在菲律宾海取得了微微型生物颗粒样品和光衰减剖面资料,然后对三种常见的微微型颗粒(原绿球藻,聚球藻和自养真核细胞)丰度及其光学性质做了初步分析和估算。研究结果表明,菲律宾海原绿球藻的丰度最高,其次为聚球藻,自养真核细胞的丰度最低。3种微微型颗粒的光散射系数同水体剖面的光衰减系数(cp)具有明显的相关关系。3种微微型颗粒的散射作用仅占总光衰减系数的5.1%,其中原绿球藻、自养真核细胞和聚球藻分别占2.6%,2.2%和0.3%。

Abstract: The pico-planktonic particles and optical beam attenuation profiles were sampled for the upper water columns of the Philippine Sea in autumn 2004.Three typical species, Prochlorococcus, Synechococcus and autotrophic eukaryotes were determined by flow cytometry techniques, and their abundances and optical scattering properties were subsequently examined.Results indicate that Prochlor ococcus is one most abundant population, then the Synechococcus, and the abundance of autotrophic eukaryotes is relatively lowest.The bulk optical scattering coefficients of three particles correlate with the beam attenuation coefficients of the water column.Among these three populations, the autotrophic eukaryotes and Prochlorococcus are the most significant contributors to the beam c_p(2.2% and 2.6%, respectively) via scattering, and only 0.3% can be attributed to Synechococcus.Only 5.1% of beam c_p can be accounted for by the bulk scattering of three particles.
