Abundance of mesozooplankton taxa during Polarstern cruise ARK-II/2 (PS05, MIZEX)

Abundances of the life stages of zooplankton taxa were calculated in the Arctic Ocean during Polarstern cruise ARK-II/2. Samples were collected in vertically hauled nets with a Multinet midi (Hydrobios, Kiel), which is equipped with five nets (mesh size: 200 µm). The water volume filtered was measured with a flowmeter attached in the net. Further details on sampling and analysis methodology can be found at Smith et al. (1986). The zooplankton samples were taken as part of the international Marginal Ice Zone Experiment (MIZEX) that was designed to study the atmospheric, oceanic, and ice interactions in the Fram Strait region of the Greenland Sea.

本数据集基于极星号（Polarstern）科考船ARK-II/2航次在北冰洋的采样数据，测算得到各浮游动物类群不同生活史阶段的个体丰度。采样采用基尔Hydrobios公司制造的Multinet midi垂直拖网系统完成，该系统搭载5个网体，网目尺寸为200微米。网体配套的流量计可测得过滤水体的体积。有关采样与分析方法的详细细节可参见Smith等（1986）的研究文献。本次浮游动物采样隶属于国际边缘冰区实验（Marginal Ice Zone Experiment, MIZEX）项目，该项目旨在探究格陵兰海弗拉姆海峡区域的大气、海洋与海冰相互作用过程。
