Global Plankton Database: inventory and data for cruise ML14

Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 0.125 mm. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through standard depths (0-10, 10-25, 25-50, 50-100, 100-200, 200-300, 300-500, 500-1000 m) and closed at the upper depth level. Depth of tow was evaluated by wire paid out and the angle of wire inclination. The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and processed on return to the laboratory. All of copepods were identified to genus level, other taxanomic groups - to type, class, order and family levels.

中型浮游动物（Mesozooplankton）样本采用环径36 cm、网目尺寸0.125 mm的开合式JUDAY网采集。该网具采用南森机械锁定系统（Nansen mechanical lock system）作为开合机构，可沿垂直方向在预设标准水层（0-10 m、10-25 m、25-50 m、50-100 m、100-200 m、200-300 m、300-500 m、500-1000 m）间拖曳，并在上层水层位置闭合。拖曳深度通过放出的钢缆长度以及钢缆倾斜角度进行测算。采集得到的10-20 ml样本经3%-4%缓冲甲醛溶液固定，返回实验室后开展后续处理。所有桡足类（Copepods）均鉴定至属级分类阶元，其余分类类群则分别鉴定至型、纲、目及科级分类阶元。
