摘要
通过对2001年4月中亚强沙尘暴过程在中国、韩国、日本和北美大陆地面PM10观测结果进行统计分析，推算出了北太甲洋PAPA地区的沙尘沉降通量，结合同期PAPA地区的海洋表层有机碳和叶绿素观测结果，探讨了北太平洋沙尘与海洋生物兴衰的关系．结果表明，本次强沙尘暴过程可以给PAPA地区带去大约3．1-5．8μg／m^3的风成Fe元素，它激发了海洋生物泵。引起海洋浮游植物的快速繁盛．
Through a statistical analysis on the surface PMto measurements in China, Korea, Japan and North America during a strong dust storm event from mid-Asia in April 2001, dust deposition fluxes were calculated for the PAPA region in North Pacific. Combining the dust depositions with the coinstantaneous observations of POC （Particle Organic Carbon） and chlorophyll from the PAPA-sea surface, the relationship between continental dust and marine phytoplankton was discussed. The results showed that the strong dust storm could transport about 3.1 -5.8μg/m^3 aeolian Fe from mid-Asia to PAPA region triggering the biology pump and raising the productivity of phytoplankton.
