Global Plankton Database: inventory and data for cruise PV29

Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh sizes of 125 µm. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through depths (0-10, 10-25, 25-50, 50-100, 100-200 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.
