Makrozooplankton at ALOHA Station during cruise HOT-53

Nets are towed obliquely at approx. 1 knot, from the surface to approx. 175 m. Towing time is approx. 20 minutes. Zooplankton (weak swimmers >200µm) are collected using oblique tows of a 1 m**2 net (3m length) with 202µm mesh Nitex netting.

该数据集的浮游动物样品采集采用斜拖网作业方式：以约1节的航速，将网具从表层斜向下放至约175米水深，单次拖曳时长约20分钟。本次采样使用网口面积1平方米、网身长3米、网目孔径为202微米的尼替克斯（Nitex）网布制作的网具，采集游动能力较弱、粒径大于200微米的浮游动物（Zooplankton）。
