许多最近的研究在海洋调查了溶解的铝(艾尔) 的滋养类型的侧面。溶解艾尔的重要清除能在浮游植物花蕾期间发生，但是机制仍然保持不清楚。在南部的黄海(SYS ) 的溶解艾尔的分发在冬季被调查并且触发 2009。在春天采样巡航期间在格子车站跟随大小，超过 100 h 的二漂流锚调查被进行在春天浮游植物花蕾(SPB ) 期间跟踪溶解艾尔集中的变化。在 SYS 的溶解艾尔的集中在 4 月在三月和 1020 nmol/L 在 2 月从 40 nmol/L 减少了到 30 nmol/L，当时 Chl 的集中一增加了从 < 在三月到的 2 g/L > 在 4 月的 4 g/L。在 SYS 的溶解艾尔的集中与浮游植物花蕾的发展显著地减少了，它显示了从水列的溶解艾尔的生物清除。溶解艾尔的比例由不同浮游植物种类从水列清除了在二个漂流的车站不同，与比 dinoflagellates 的硅藻表明的更大的移动效率。从 Chl 收集的浮游植物样品最大的层与踪迹金属被洗干净试剂(oxalate-EDTA-citrate，作为盐答案缩短， Tovar-Sanchez 等， 2003 ) 启用清除表面(细胞外) 并且与要区分的浮游植物联系的细胞内部的艾尔水池。39 被发现到百分之 96 彻底的艾尔在内部水池被存在，它显示生物吸收是清除的重要方法在 SYS 在浮游植物花蕾期间溶解了艾尔。

英文摘要：

Many recent studies have investigated the nutrient-type profiles of dissolved aluminum （A1） in the ocean. Significant scavenging of dissolved A1 can occur during phytoplankton blooms, but the mechanism remains unclear. The distribution of dissolved A1 in the southern Yellow Sea （SYS） was investigated in winter and spring 2009. Following measurements at grid stations during the spring sampling cruise, two drifting anchor surveys of more than 100 h were conducted to trace the variation of dissolved AI con- centration during the spring phytoplankton bloom （SPB）. The concentration of dissolved A1 in the SYS decreased from 40 nmol/L in February to 30 nmol/L in March and 10-20 nmol/L in April, while the concentration of Chl a increased from 〈 2 ~tg/L in March to 〉 4 I.tg/L in April. The concentration of dissolved A1 in the SYS decreased significantly with the development of the phyto- plankton bloom, which indicated biological scavenging of dissolved A1 from water column. The proportion of dissolved A1 scav- enged from water column by different phytoplankton species differed at the two drifting stations, with greater removal efficiency demonstrated by diatoms than dinoflagellates. Phytoplankton samples collected from the Chl a maximum layer were washed with trace metal clean reagent （oxalate-EDTA-citrate, abbreviate as oxalate solution, Tovar-Sanchez et al., 2003） to enable the sur- face-scavenged （extracellular） and intracellular A1 pools associated with phytoplankton to be differentiated. Thirty-nine to ninetysix percent of the total A1 was found to be existed in the interior pools, which indicated that biological absorption was the important way to scavenge dissolved A1 during phytoplankton blooms in the SYS.
