Zooplankton wet weight (MR19-03C)

Zooplankton samples were collected by vertical haul of Quad-NORPAC nets at 58 stations in the Pacific sector of the Arctic Ocean. The Quad-NORPAC net (mesh sizes: 335, 150 and two of 63 micrometre [one is for a fixed sample and the other has a large-sized cod-end to collected fresh samples for incubation], mouth diameter: 45 cm) was towed between the surface and the depth of 150 m (or the bottom - 10 m at stations where the bottom was <150 m) at all stations.

在北冰洋太平洋扇区的58个调查站位，采用垂直拖网作业方式采集浮游动物样本，所用网具为Quad-NORPAC网（Quad-NORPAC）。该网具的网目尺寸分别为335、150以及两种63微米规格：其中一种用于制备固定样本，另一种配备大型囊网（cod-end）以采集鲜活样本用于培养实验，网口直径为45厘米。所有站位的拖网作业均在表层至150米水深区间开展；若站位所在海域水深小于150米，则拖曳至距海底10米处停止。
