Mesozooplankton average mass during Professor Vodyanitskiy cruise PV30_1, Part III@en

Mesozooplankton was collected in vertical hauls covering three layers: 0 m - upper border of thermocline, the layer of thermocline, lower border of thermocline - 200 m with Juday net with mesh size 0.145 mm and a mouth area of approximately 0.1 m**2. Depth of tow is evaluated by wire paid out and the angle of wire inclination. Nansen's closing device.本研究采用网目尺寸为0.145 mm、口门面积约0.1 m²的裘迪网（Juday net），通过垂直拖网采集中型浮游动物（Mesozooplankton），拖网覆盖三层水体：0 m至温跃层（thermocline）上边界、温跃层本体、温跃层下边界至200 m水深。拖网作业的水深通过放出的缆绳长度及缆绳倾斜角度进行评估，作业过程搭载南森式闭锁装置（Nansen's closing device）。
