Zooplankton abundance based on RMT1 net during SIPEX winter-spring transition

Zooplankton were collected during the winter-spring transition with an RMT8+1 net during the SIPEX voyage in 2007. Only the RMT1 data are presented here. The net was deployed on an oblique tow from the surface to 200 m. The catch in each cod-end was preserved in 5% borax-buffered formaldehyde. The samples were subsplit in the laboratory with a Folsom splitter if needed and examined under a Leica M12. Species were examined to the lowest taxon possible - to species for copepods and euphausiids and to higher levels for other taxa.

2007年SIPEX航次（SIPEX voyage）期间，研究人员于冬春转换期采用RMT8+1型网（RMT8+1 net）采集浮游动物（Zooplankton）。本数据集仅收录RMT1采样数据（RMT1 data）。该网以从海面至200米的斜向拖网方式布放。每个网囊（cod-end）内的捕获样品均保存于5%硼砂缓冲甲醛溶液（5% borax-buffered formaldehyde）中。实验室内如需分样，则使用Folsom分样器（Folsom splitter）进行分样，并借助徕卡M12（Leica M12）体视显微镜开展镜检。物种鉴定尽可能推进至最低分类单元（taxon）：其中桡足类（copepods）和磷虾类（euphausiids）鉴定至物种水平，其余类群则鉴定至较高分类阶元。
