Makrozooplankton at ALOHA Station during cruise HOT-128

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 420µm mesh Nitex netting.

网络以约1节的速度斜向牵引，从水面至约175米深处。牵引时间约为20分钟。利用1平方米（长度为3米）的网具，其网眼尺寸为420微米的Nitex网布，通过斜向牵引收集浮游动物（游泳能力较弱，直径大于200微米）。
