Makrozooplankton at ALOHA Station during cruise HOT-99

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.

网络以约1节的速度从水面牵引至约175米深处，牵引时间约为20分钟。利用1平方米（3米长度）的 Nitex网眼网（网眼尺寸为202µm）进行斜向牵引，收集浮游动物（游泳能力较弱，直径大于200µm）。
