The results of size-fractionated productivity showed that the contribution of picoplankton to total productivity was the largest in the Southern Atlantic ocean and Drake Passage,that of nanoplankton and netplankton were approximate.

• 分级初级生产力的结果表明 ,在南大西洋和德雷克海峡对总初级生产力的贡献以微微型浮游生物为最大 ,微型浮游生物和小型浮游生物的贡献大致相当。
