中文摘要
这项工作是为了提高我们对海洋雪在(寡营养)北太平洋中央环流中的作用的理解,在那里关于这类问题的数据尤其缺乏。ALOHA站的Souba海水样本将从聚集过程本身的角度进行评估:海洋雪的组成、丰度、大小和结构。宏观聚集率和海洋雪停留时间将使用234:238U不平衡技术独立估计。数据分析将受到高质量的生物、化学和物理水柱数据的限制。
英文摘要
This work is to improve our understanding of the role of marine snow in the (oligotrophic) North Pacific Central Gyre where data regarding such questions is especially lacking. Souba samplings of seawater at station ALOHA will be evaluated from the perspective of the aggregation process itself: marine snow composition, abundance, size and structure. Macro-aggregation rates and marine snow residence times will be independently estimated using 234Th:238U disequilibria techniques. Analysis of data will be constrained by high quality biological, chemical and physical water column data.
