Makrozooplankton at ALOHA Station during cruise HOT-55@en

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.拖网以约1节的速度进行斜向拖曳，作业水深范围为表层至约175米，单次拖曳时长约20分钟。本次采样使用面积1平方米、长3米且网目尺寸为202微米的Nitex网布拖网进行斜向拖捕，以采集浮游动物（Zooplankton，即游泳能力较弱、粒径大于200微米的生物）。
