Makrozooplankton at ALOHA Station during cruise HOT-121

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.

数据采集过程中，网络以约1节的速度斜向拖曳，从水面至约175米深度。拖曳时间约为20分钟。利用1平方米（3米长度）的斜向拖曳网（202微米尼特克斯网眼）收集浮游动物（游泳能力较弱，直径大于200微米）。
